16. AbstractThe Weather Message Switching Center Replacement (WMSCR) will serve as the FederalAviation Administration (FAA) gateway for the receipt and distribution of weatherdata and Notice to Airmen (NOTAM) within the National Airspace System (NAS).

In December 1981, the FAA chartered a comprehensive NAS Plan for modernizing andimproving air traffic control (ATC) and airway facilities through the year 2000.As part of the NAS Plan in 1983, the Air Traffic Service operation and requirementsfor the WMSCR were published.

The purpose of the WMSCR system is to replace the current Weather Message SwitchingCenter (WMSC) system in Kansas-City, Missouri. It will support all functionsrelated to weather processing presently performed by the WMSC. In addition, theWMSCR will collect NOTAMs from the Automated Flight Service Station (AFSS)environment for processing by the Consolidated NOTAM System Processor (CNSP) andwill store and distribute the processed NOTAMs received from the CNSP.

The WMSCR will be comprised of two identical nodes and the National Weather ServiceTelecommunications Gateway (NWSTG) WMSCR Interface Device (NWID). The nodes willbe located at the National Aviation Weather Processing Facility (NAWPF) sites atSalt Lake City, Utah and at Atlanta, Georgia. The NWID will be located atLeesb,", Virginia. Each node will have the capability of servicing the entiregeograpaical airspace system 24 hours a day, 7 days a week.

EXECUTIVE SUMMARY

As part of the National Airspace System (NAS) Plan, the Weather Message SwitchingCenter Replacement (WMSCR) system will replace the current Weather MessageSwitching Center (WMSC) system in Kansas City, Missouri. In December 1981, theFederal Aviation Administration (FAA) chartered a comprehensive NAS Plan formodernizing and improving air traffic control (ATC) and airway facilities (AF)through the year 2000.

The WMSCR will support all functions related to weather processing presentlyperformed by the WMSC, and store and distribute processed Notice tc Airmen (NOTAM)received from the Consolidated NOTAM System Processor (CNSP). The WMSCR Systemwill rely on the NAS Data Interchange Network Packet Switched Network (NADIN PSN)for the majority of communications support. The WMSCR functions as the FAA gatewayto and from the National Meteorological Center (NMC) via the National WeatherService Telecommunications Gateway (NWSTG). Therefore, the WMSCR will be the sourceof weather products for the NAS.

The WMSCR system consists of two identical nodes and the NWSTG WMSCR InterfaceDevice (NWID). The nodes will be located at the National Aviation WeatherProcessing Facility (NAWPF) sites in Salt Lake City, Utah and in Atlanta, Georgia.The NWID is to be installed at Leesburg, Virginia. Each node will providegeographical redundancy and will increase operational availability. Each WMSCRnode serves approximately half the system. If one node fails, the surviving nodeassumes complete system operation.

The WMSCR will be capable of continuous 24-hour-a-day, 7-day-a-week operation. Itis planned to become operational in 1992, and the system lifetime is anticipated tobe at least 10 years.

i, INTRODUCTION.

As part of the National Airspace System (NAS) Plan, the Weather Message SwitchingCenter Replacement (WMSCR) system will replace the current Weather MessageSwitching Center (WMSC) system in Kansas City, Missouri. The WMSCR will performall current weather data handling functions of the WMSC. In addition, the WMSCRwill collect Notice to Airmen (NOTAM) from the Automated Flight Service Station(AFSS) environment for processing by the Consolidated NOTAM System Processor (CNSP)and will store and distribute the processed NOTAMs received from the CNSP.

The WMSCR system will rely on the NAS Data Interchange Network Packet SwitchedNetwork (NADIN PSN) for the majority of communications support. The WMSCRfunctions as the Federal Aviation Administration (FAA) gateway to and from theNational Meteorological Center (NMC), via the National Weather ServicuTelecommunications Gateway (NWSTG). Therefore, the WMSCR system will be the sourceof weather products for the NAS.

The WMSCR system consists of two identical nodes and the NWSTG WMSCR InterfaceDevice (NWID). The nodes will be located at the National Aviation WeatherPr-ocessing Facility (NAWPP) sites at Salt Lake City, Utah, and at Atlanta, Georgia.The NWID is to be installed at Leesburg, Virginia.

Each node will provide geographical redundancy and will increase operationalavailability. Each WMSCR node serves approximately half the system. If one nodefails, the surviving node assumes complete system operation.

The WMSCR will be capable of continuous 24-hour-a-day, 7-day-a-week operation. Itis planned to become operational in 1992.

1.1 PURPOSE.

The purpose of the Operational Test and Evaluation (OT&E)/Integration Test Plan isto provide the overall test philosophy and approach as well as to define thetesting activities necessary to ensure the integration of the WMSCR system withinthe NAS environment. To accomplish this objective, the WMSCR, an end-statesubsystem, must be operationally integrated with existing NAS subsystems.

The OT&E/Integration Test Plan defines the overall planning, coordination, criteriaand general methods for the WMSCR OT&E/Integration test activities. These testactivities include detailed testing requirements to verify the NAS-SS-1000requirements, Volumes I to V, as applicable, Air Traffic Service (ATS) operationalrequirements and NAS Interface Requirements Document (IRD) system-levelrequirements. The WMSCR NAS system-level requirements are cross-referenced in theWMSCR Test Verification Requirement Traceability Matrix (TVRTM). (See appendix A.)

Detailed *e.,- procedures will be prepared as a separate document in accordance withFAA Standard 024a, Preparation of Test and Evaluation Documentation.

3. T&E PHILOSOPHY.

The WMSCR overall test and evaluation (T&E) philosophy will verify operati ,)-

requirements at the system and subsystem levels in accordance with NAS-SS-'.....Volumes I througi. V, as applicable, and the WMSCR Master Test Plan (MTP)Verification R-quirement Traceability Matrix (VRTM). The success criterida forthese requ" ments will be detailed in the OT&E/Integration test procedures.

Additionally, the T&E philosophy will verify the WMSCR system capabii't-., toproperly interface and function with other NAS subsystems and to ensure that theWMSCR will be operationally effective and suitable when implemented into the NAS-

FAA Order 1810.4A delegates the responsibility for OT&E/Integration testing to IheEngineering Test and Evaluation Service, Communications/Navigation/SurveiilanceDivision, ACN-200, Weather and Remote Maintenance Monitoring Systems Branch,ACN-250, at the FAA Technical Center.

At the present time, a WMSCR system is not scheduled for delivery to the FAATechnical Center; therefore, the WMSCR/OT&E Integration test will be conducted byACN-250 at the designated operational test sites. In accordance with the MTP andFAA Order 1810.4A, the subsystems identified in this test plan will be tested.Where the actual subsystem is not available, emulation of that NAS subsystem willbe used, except in those cases where the subsystem has not yet been baselined. Inthese particular cases, the NAS-SS-1000 requirements will be deferred.

ACN-250 is tasked by the Weather and Flight Service Station Engineering Division,Weather Processors Branch, ANW-130, to accomplish the WMSCR OT&E/Integration test.ACN-250 will support ANW-130 in the monitoring of the Factory Acceptance Test (FAT)and Site Acceptance Test (SAT). In addition, ACN-250 will monitor OT&E/Shakedowntest. In agreement with ANW-130, operational and NAS requirements that may beverified during the conduct of the FAT and SAT test activities will not beduplicated during OT&E/Integration test.

4. T&E APPROACH AND CONCEPT.

To determine the overall interoperability of the WMSCR System within the NASenvironment, integration testing requires an environment as near operational aspossible. The TWMSCR OT&E/Integration test will include verification to determinethat the hardware/software will perform in a NAS environment and in accordance withNAS system-level and subsystem-level operational requirements.

A building block approach will be employed in the implementation of the AMSCROT&E/Integration test process. This approach provides an orderly sequencp of tes-sthat establishes a baseline for subsequent WMSCR OT&E/Integration testiz

The WMSCR OT&E/Integration test approach will be guided by the ISO/OSI 7498 OpenSystem Interconnect (OSI) Model. (See figure 4-1.)

The following sequences will be used as a reference point to construct a testbaseline for the operational WMSCR System. This baseline will include gathering aweather and NOTAM information database that will be used in conjunction with thedistribution and communications functions addressed in paragraph 4.1.

a. The initial WMSCR Integration test will begin with a subset of WMSCRoperator functions which will include start-up procedures, diagnostics and systemconfiguration parameters.

b. WMSCR to NWSTG - This test will obtain and verify an operational database,in accordance with Federal Coordinator for Meteorological Service Standards(FCM-S2) and World Meteorological Organization (WMO) weather format standards.After obtaining a valid weather database, the WMSCR operator console will beexercised.

c. WMSCR to AWP - This test will verify that WMSCR sends and receives weatherto/from the AWP and NOTAM data to/from the CNSP via the AWP.

d. WMSCR to Coded Time Source (CTS) - This test will verify synchronizationwith the coordinated CTS.

e. WMSCR to CNSP - This test will verify that the WMSCR can receive and storeprocessed NOTAMS from the CNSP.

f. To complete the first building block of testing, the WMSCR OT&E/Integrationtest will complete the WMSCR to NADIN X.25 protocol conformance certificationprocess as described in the NADIN II System Specification, FAA-E-2770b,paragraph 3.7.7.3. This will enable the WMSCR to connect to the NADIN PSN usersfor further testing.

Upon successful verification of the NAS requirements for the above sequences, tJMSCROT&E/Integration testing will verify the interface requirements of the users thatemploy the NADIN PSN as an intermediate pathway.

The WMSCR OT&E/Integration testing supports string testing through the NADIN PSN tothe end-state subsystem; however, the OT&E/Integration testing does not assumeresponsibility for the success or failure of that string.

The WMSCR/NADIN PSN users by design have common interface characteristics.The testing of WMSCR/NADIN PSN users will verify the general requirements of eachWVMSCR node to distribute weather and NOTAM information to each of the users. Thereare unique weather and NOTAM requirements for each subsystem/user that will betested. The WMSCR also collects data, such as observations, forecasts, andwarnings from the WMSCR/NADIN PSN users, which are stored and further distributed.The WMSCR/NADIN PSN users can selectively request data from the WMSCR.

4.1 TEST CONFIGURATIONS AND CATEGORIES.

The WMSCR OT&E/Integration test will employ five configurations which representlogical groups to operationally test the WMSCR system into the NAS environment.The configurations will validate the communications function, (OSI layers 1-3).This function will provide for the acquisition and dissemination of weatherproducts and NOTAM information over the interfacing communications network anddedicated circuits. The test configurations are as follows:

7

a. Test Configuration #1 will test the communications function of those NAS

subsystems/users that are directly connected to a WMSCR node.

b. Test Configuration #2 will test the communications function of those NASsubsystems which interface to the WMSCR node as WMSCR/NADIN PSN users.

c. Test Configuration #3 will test the communications function of those NASsubsystems which interface to the WMSCR node as WMSCR/NADIN MSN users.

d. Test Configuration #4 will test the communications function of those NASsubsystems which interface to the WMSCR node as WMSCR/NADIN APAD users.

e. Test Configuration #5 will test the communication functions for the totalsystem network of WMSCR subscribers/users.

Withia each test configuration are test categories which represent the WMSCRsubsystems/users. Each category will test the WMSCR processing and distributionfunction for weather and NOTAM message types and operational interfacerequirements. The test categories will provide a uniform interface for testingdata formats and procedures for all communication circuits (OSI layers 4 and 7)independent of the data types, protocols, and formats in use on the circuit.

Throughout the OT&E/Integration test plan, TVRTM requirements are shown by theassigned TVRTM requirement number (xxxx). The same requirement number may appearin more than one test configuration/category. If a requirement is listed in more:han one test configuration/category, then the requirement is partly satisfied byeach test configuration/category that the requirement is assigned to.

For ease of identification, a letter has been assigned to each test category(e.g., Category A, Category B). These test configurations and test categories areorganized to allow testing of common requirements. (See figure 4.1-1.) They are asfollows:

Test Configuration #1: The subsystems/users directly connected to the WMSCR nodeinclude the following:

Category Subsystem/User

A WMSCR operator

Test Configuration #2 will begin after the completion of the NADIN X.25 protocolconformance certification process. The WMSCR/NADIN PSN users (category Fthrough R), by design, have common interface characteristics. (See figure 4.2-2.)

The objectives of this test configuration are to verify the following:

a. The network layer requirements will verify:

1. The procedures for establishing, maintaining, and clearing of thenetwork connection by means of transferring packets across the Data TerminalEquipment/Data Circuit-Terminating Equipment (DTE/DCE) interface.

2. The data routing, circuit multiplexing, flow control, and error recoveryfor packets transmitted across the DTE/DCE interface.

b. The data link layer requirements will verify:

1. The reliable, error free, and efficient exchange of data in spite oferrors which may occur in transmission.

2 The LAPB and multilink procedure as specified in NAS-IR-43020001.

(1003)


This configuration supports data exchange with the NADIN Message Switching Network(MSN) users connected to the NADIN 1A message switch. The objective of this testconfiguration is to verify the following:

a. The network connection to the NADIN PSN gateway product distribution, datatransfer, product transmission from the NADIN MSN users to the WMSCR, andtermination of call after completion of message transmission.

Since the interface between the WMSCR and the NADIN MSN users will be implementedthrough the NADIN PSN (see figure 4.2-3), the data link and physical layers havebeen previously tested.

The Asynchronous Packet Assembler/Disassembler (APAD) are part of the NADIN PSN andappear to WMSCR as packet network users. (See figure 4.2-4.) The APADs disgributealphanumeric weather and NOTAM data to the users through 1200-9600 bits per second(bps) asynchronous circuits. The objectives of this test configuration are toverify the following:

a. The establishment of a call from the WMSCR system to each NADIN AsynchronousPAD device using the X.25 procedures specified in NAS-IR-43020001;

b. The CCITT RECOMMENDATION X.29 procedure for Exchange of Control Informationand User Data between a Packet Mode DTE and a Packet Assembly/Disassembly (PAD)Facility.

(1003)

Test Confipuration #5:

Test configuration #5 consists of a network of all available systems that willsimultaneously test the exchange of weather products with the community of WMSCRusers.

(1003) (2020) (2021)

4.3 DETAILED TEST CATEGORIES.

Each test configuration has test categories which represent the WMSCRsubsystems/users. These categories verify the WMSCR collection and disseminationof weather and NOTAM products across the operational interface. Each categoryincludes a listing of the operational interface products.

The five primary functions to be tested in each category will be the applicationlayer, the establishment of an application connection, product distribution,product request/reply, and error recovery. With the exception of categories A, C,and D, the functional characteristics of the WMSCR users are organized inaccordance with the ISO 7498 reference model. Categorie3 A and D use the DECNETarchitecture model which is functionally similar to the ISO 7498 reference model.

a. Application Layer: The application layer contains the parts of theapplication process that are responsible for performing information transfer.This layer defines the procedures for the exchange of weather and vector graphicproducts. The application layer directly uses the services provided by theunderlying transport layer to transmit and receive the Application Data Unit(ADU). The ADU is the format used to transfer all data between the WMSCR andsubsystems/users as specified in figure 4.3-1. An ADU consists of two parts, aheader and an information portion. The ADU encapsulates the weather and vecto-graphic messages that are described in the following category descriptions.

b. Establishment of the Application Connection: Where applicable, the WMSCRsystem establishes an application connection by requesting a transport connectionto the intended WMSCR subsystem/user through the transport layer. This transportconnection will be verified to identify the source and destination reference numberassociated directly with the application connection being established.

c. Product Distribution: The product distribution (PD) function of theapplication layer of the WMSCR node is to disseminate a predetermined set ofproducts to each user. The PD function of the application layer of a .ISCRsubsystem/user is to disseminate a predetermined set of products to a WMSCR node.This test configuration will capture this exchange by recording the ADU andverifying that the identifier for the product distribution is in the field of :heADU header for the two ADU types.

d. Product Request/Reply: The product Request/Reply capability allows theusers to access the data stored in the WMSCR dynamic weather and NOTAM database(s.The Request/Reply transactions are contained within an ADU unit and will berecorded and verified for all testing categories.

e. Error Recovery: In the event of unsuccessful data delivery or networkfailure, the application layer will inform the subsystem of the failure.

4.4 SUBSYSTEM AVAILABILITY.

Currently the OT&E/Integration test plan addresses the NAS end-state system(see figure 4.4-1) and expansion to non-NAS external users. However, the finaltest configurations and categories may be tested with interim operationalsubsystems.

Configurations I through 5 are grouped by common testing requirements and,therefore, the replacement of subsystems with an interim operational subsystem willnot effect the configuration testing requirements.

Furthermore, because the WMSCR has an on-line capability to tailor productdistributions to individuals or groups of users, a replacement subsystem will noteffect the category validation of the product distribution function. For example,the Service A user, whether it is a NAS end-state user or an interim user willreceive the same Service A product distribution.

Currently there is a NAS Change Proposal (NCP) in progress to change the NAS end-state configuration. The WMSCR to other WMSCR will change from a NADIN permanentvirtual circuit (PVC) to a dedicated circuit and the CNSP will change from adedicated circuit to a PVC. However, the product exchanged via a dedicated circuitor a PVC vi.l not effect the validation of the products exchanged.

If the NADIN PSN is not available prior to the start of OT&E/Integration testing, acommercial packet switching network service could provide an alternative to theNADIN PSN for testing of all configurations except for NADIN MSN Gateway users.NADIN MSN Gateway user requirements would be deferred until NADIN II becomesavailable.

4.5 CRITICAL REQUIREMENTS.

The flow of weather and NOTAM data is the critical requirement for the IWMSCRSystem. The dedicated interfaces that support this flow are considered critical.These interfaces include the following test categories:

Category B - WMSCR/NWSTGCategory C - WMSCR/AWPCategory D - WMSCR/CTSCategory E - WMSCR/CNSPCategory F - WMSCR/Other WMSCR

4.6 VERIFICATION METHODS.

Methods of verification used to test the requirements identified in the TVRTM,appendix A, are taken from the NAS-SS-1000 and are defined as follows:

a. Test (T). Test is a method of verification wherein performance is measuredduring or after the controlled application of functional and/or environmentalstimuli, Quantitative measurements are analyzed to determine the degree ofcompliance. The process uses laboratory equipment, procedures, items, and/orservices.

b. Demonstration (D). Demonstration is a method of verification wherequalitative determination of properties is made for an end-item including softwareand/or the use of technical data and documentation. The items being verified areobserved but not quantitatively measured in a dynamic state.

c. Inspection (I). Inspection is a method of verification to determinecompliance without the use of special laboratory appliances, procedures, orservices, and consists of a nondestructive static-state examination of thehardware, software, and/or the technical data and documentation.

d. Analysis (A). This method of verification consists of comparing hardwareor software design with known scientific and technical principles, procedures, andpractices to estimate the capability of the proposed design to meet the mission andsystem requirements.

4.7 NAS QUALIFICATION STATUS.

If a NAS end-state requirement still exists at the time of OT&E/Integration testingand cannot be tested by live or simulated means, a "Q" will be assigned to thisrequirement. This "Q" status means the subsystem does not presently exist in theNAS; therefore, the requirement will be deferred and tested at a future date.

7.2 OPERATING AND CONTROL DOCUMENTS.

7.2.1 Monitoring/Verifying of Development Test and Evaluation (DT&E).

As stated in section 3.0, when test results of lower-level testing (i.e., FAT/SAT)may be used to satisfy operational or NAS requirements, these requirements will notbe duplicated. When this is the case, the Contractor Test Case identificationnumber and supporting documentation for traceability for the verification of thisTVRTX i:equirement will be noted in the OT&E/Integrarion Test Procedures.

7.2.2 Test Procedures.

The WMSCR OT&E/Integration Test Procedures will contain step-by-step instructionsfor conducting the verification of requirements associated with each testconfiguration and category. To facilitate traceability, each test procedure(where applicable) will include the OT&E VRTM requirement number and the NAS IRDrequirement number.

A protocol analyzer will be used to nonintrusively capture data transferred acrossthe operational interface between the WMSCR and the subsystems and, therefore, willbe an integral part of the test procedures. The test procedures will provide thepass/fail criteria. The protocol analyzer will provide visibility into thefollowing:

a. The physical layer - X.21bis, voltage/signaling levels,b. The data link layer - frame format and error recovery,c. The network layer - addressing, PVC and Switched Virtual Circuit (SVC),d. The transport layer - establish a connection with the user and delivery,e. The application layer - ADU format and product distribution.

From this data the pass/fail of the requirement will be determined.

In conjunction with field personnel, WMSCR operator test procedures will bedeveloped to include:

a. The Service A product mix for External users,b. Table of catalog numbers for WMSCR product distribution,c. ICAO addressing for MSN users.

7,2.3 Test Log.

A Test Conduct Log (see appendix B) will be prepared for each test category.

7.2.4 Test Observer/Monitor Record.

Test observer/monitor notes will be recorded on the Test Observer/Monitor Record(see appendix B) and sigTed by the observer.

41

7.2.5 Test Discrepancy Reports.

The test manager is responsible to ensure that all discrepancies observed duringthe tests are documented. The form located in appendix B should be used todocument test discrepancies.

a. Program Technical Report - Form 6100.1 is initiated when a problemis related to a non-WMSCR subsystem/equipment maintenance-type discrepancy.FAA-OR-1l00.45A, Program Te-li-iml Report Procedures, delineates the pur--ze anduse of this form.

Any additional equipment needed will be defined inthe test procedures.

9.2 DATA ANALYSIS.

Data analysis for test categories will be accomplished by comparison of actual testoutput data to the success criteria defined in the test procedures. The requireddata will be gathered from recording devices, (e.g. protocol analyzer), printedoutputs, monitor displays, etc., by designated test team personnel during testing.

42

The protocol analyzer will be positioned to capture the data on the circuit betweenthe WMSCR and NADIN PSN users (configurations 2 through 5). Analysis of this datacaptured at the operational interface will be the basis for pass/ fail criteria forthe WMSCR.

The analysis of the data captured will produce a hard copy report of those weatherproducts after the supervisory frames and unnumbered frames of the OSI model areremoved. This group represents a sample of weather products captured across theoperational in-erface within a giver time int:aal. Statistical samplir.gtechniques will be applied to verify the weather sample meets the 24 hour productdistribution. The weather product sampling analysis will be based on the followingcriteria:

a. The composition of the weather distribution (frequency),b. The format of the weather product (ADU),c. The size of the weather product,d. The confidence level of 95 percent.

9.3 TEST SITE CONFIGURATION.

The WMSCR OT&E/Integration test will be conducted by ACN-250 at the designatedoperational test sites. These test sites include the Air Route Traffic ControlCenter (ARTCC) at Leesburg, Virginia, the NAWPF in Atlanta, Georgia, and Salt LakeCity, Utah.

GLOSSARY OF TERMS

Addresses - A special sequence set of bits or characters assigned to a specificterminal within a communications network, or on a multiterminal circuit, for thepurpose of routing messages to a specific destination(s).

Analysis - This method of verification consists of comparing hardware or softwaredesign with known scientific and technical principles, procedures, and practices toestimate the capability of the proposed design to meet the mission and systemrequirements (NAS-SS-I000, Vol 1).

Application Data Unit - The Application Data Unit (ADU) is the data unit associatedwith the highest layer of the (ISO/OSI) model. It consists of the presentationlayer (or next lower layer) and the application header.

Application Layer - Layer 7 of the OSI model. Provides access to the OSIenvironment for users and also provides distributed data processing services.

Asynchronous User - Asynchronous users are a group of WMSCR subscribers connectedvia a protocol converter located at each of the NADIN II packet network nodes.These users consist of airlines and commercial subscribers of the "604" service.Each asynchronous subscriber receives deta in 7-bit ASCII code with parity inasynchronous format (one start bit and one stop bit). The asynchronous protocol isoutput-only with no error-checking protocol.

Circuit - A communications pathway between two systems or subscribers. A circuitcan be a physical pathway consisting of copper wire, microwave equipment, and thelike. It can be a conceptual entity representing the pathway over a communicationutility such as a packet switch network.

Data Circuit-Terminating Equipment - (DCE) In a data station, the equipment thatprovides the signal conversion and coding between the data terminal equipment (DTE)and the line. The DCE may be separate equipment or an integral part of the DTE orof intermediate equipment.

Data Link Layer - Layer 2 of the OSI model. Provides for the reliable transfer ofinformation across the physical link. Sends blocks of data (frames) with thenecessary synchronization, error control, and flow control.

Data Terminal Equipment - (DTE) That part of a data station that serves as a datasource, data sink, or both.

Dedicated Link - A connection between two systems that is dedicated to thatpurpose. This is as opposed to a link that uses a communications utility such asthe NADIN II packet switch network.

Demonstration - If a requirement is validated by test during first articlequalification testing and the requirements has enough significance that it is"retested" during acceptance test. -hen this acceptance testing can be indicated inthe Verification Requirement Trac_-Jility Matrix (VRTM) as a demonstration. Ingeneral, software functional requirements are validated by demonstration since thefunctionality must be observed through some secondary media.

External Interfaces - Interfaces between the NAS and systems and subsystems outsidethe NAS (NAS-SS-I000, Vol 1).

FCM-S2 Format - Federal coordinator for Meteorologist Services and SupportingResearch, standard formats for weather data exchange among automated weatherinformation systems. The Weather Message Switching Center Replacement ( T MSCR) willhandle vector graphics using FCM-S2 formats.

Functional Interface - Interfaces which interact across non-material boundaries andare described in terms of information transfer characteristics described in theInternational Standards Organization/Open System Interconnect (ISO/OSI), SevenLayer Model, (NAS-SS-IO00, Vol 1).

Functional Requirement - Type of requirement that describes what the system must doto satisfy the operational requirements. A functional requirementmust have an action verb and should have well defined inputs and outputs(NAS-SS-lO00, Vol 1).

Header - The initial part of a product which contains fields that define thecontents. Both World Meteorological Organization (WMO) and International CivilAviation Organization (ICAO) formatted messages have headers.

Inspection - Inspection is a method of verification to determine compliance withoutthe use of special laboratory appliances, procedures, or services, and consists ofnondestructive static-state examination of the hardware, software, and/or technicaldata documentation (NAS-SS-IO00, Vol 1).

Interface - A common functional and/or physical boundary where hardware/ softwarepersonnel interact (i.e., hardware end item with personnel)(NAS-SS-100, Vol 1).

Interface Control Documents - ICDs shall specify and control the design ofinterfaces between subsystems (NAS-SS-100, Vol 1).

Interface Requirement Documents - IRDs shall specify and control the requirementsfor interfaces between subsystems (NAS-SS-1000, Vol 1).

ISO/OSI Model - The ISO/OSI model is a seven-layer organizational mechanism fordefining the procedures and formats for data exchange between two interconnectingsystems.

Man-Machine Interface - Interfaces that encompass man-man/man-machine interactioninvolved in the command, control, operation, and maintenance of subsystems or enditems (NAS-SS-IO00, Vol 1).

Network Layer - A specific interface level in the design of a network architectureprovided by a set of operating procedures (protocols) based on a design standard,that will support compatibility between equipment providing data communications andinformation transfer services between two or more data terminal equipments and twoor more data r..mmunications equipments.

Operational Effectiveness - Operational effectiveness is the degree of successfulaccomplishment in meeting operational and technical requirements of a subsystemused by representative operational personnel. This is evaluated in the context ofthe organization, doctrine, tactics, and environment anticipated for the plannedoperational employment of the subsystem.

Operational Interface - Type of interface which interacts across a system boundaryand defines the information and services exchanged. Operational interfaces arespecified as part of the operational requirements and in the development ofoperations concept (NAS-SS-1000, Vol 1).

Operational Requirement - Type of requirement that qualifies and quantifies theservices and products which must be provided to NAS users and NAS specialists.Operational requirements should be directly related to the NAS mission and may beimpacted by a predetermined operations concept (NAS-SS-IO00, Vol 1).

Operational Suitability - Operational suitability is the capability of a subsystemto be satisfactorily integrated and employed for field use. Considerations aregiven to subsystem operation by field personnel for compatibility, reliability,human performance factors, maintenance and logistics support, safety, and trainingrequirements.

Operational Test and Evaluation (OT&E) - OT&E is test and evaluation conducted toevaluate the subsystem operational effectiveness and suitability includingcompatibility, interoperability, degraded operations, survivability,maintainability, and supportability. The OT&E also identifies deficiencies in NAShardware, software human performance factors, or operational concepts. Itencompasses an interactive process of risk reduction demonstrations and analysisand assures that NAS functionality as it existed prior to installation of a newsubsystem is not degraded.

Physical Layer - Layer I of the OS model. Concerned with transmission ofunstructured bit stream over physical medium. Deals with the mechanical,electrical, functional, and procedural characteristics of accessing the medium.

Presentation Layer - Layer 6 of the OSI model. Provides independence ro theapplication processes from differences in data representation (syntax).

Session Layer - Layer 5 of the OSI model. Provides the control structure forcommunication between applications. Establishes, manages, and terminatesconnections (sessions) between cooperating applications.

System Level - This level of verification is conducted at the FAA Technical Centeror key site. The verification will determine if the hardware to be deployed forsite installation will perform in a NAS environment and in accordance with the NASSystem Level Operational and Functional Requirements.

Transport Layer - Layer 4 of the OSI model. Provides reliable, t.aasparenttransfer of data between end points. Provides end-to-end error recovery and flowcontrol.

WMO Format - A format for the exchange of alphanumeric information.

X.25 - A standard defining procedures in the lower three layers of the ISO/OSImodel. These standards are used by the NADIN II Packet Network.
