Preface

Hazard Avoidance is a primary tenet for safety of flight in todays busy airspaceenvironment and one of the most important safety devices you can add to your aircraft isfor avoiding other aircraft. That device is the Traffic Advisory System (TAS). TAS is a

lighter-weight and more-affordable derivative of the highly successful Traffic Alert andCollision Avoidance Systems (TCAS), which were mandated for all Air Transport-category aircraft and are also found on virtually all Corporate-class turbine aircraft.Seeing and avoiding other aircraft is paramount to safety of flight, and even if you areconfident you are seeing all the traffic, it doesnt mean they can see you. Technologyhas advanced and prices have been significantly reduced to the point that now, theseaffordable TAS systems are available for virtually any general aviation aircraft, providingyou with a second set of eyes in the cockpit to help you fly more safely.

This white paper will show you the significant safety enhancement provided by TAS, andwhy Avidynes TAS600 Series provides the best performance and the best value for yourgeneral aviation aircraft.

Choosing a Traffic System

Introduction

Air Transport category aircraft have been mandated to have operational Traffic CollisionAvoidance Systems (TCAS) for over 25 years as a result of the 1986 Airport and Airway

Safety Expansion Act. This advanced technology has all but eliminated mid-aircollisions among this class of aircraft. However, there has been little evidence ofimprovement in the general aviation sector, where on average, mid air collisions occurapproximately 16 times per year, resulting in multiple fatalities.

Mid-air collisions are a growing concern throughout the world. High air traffic volume,once only a concern around congested metropolitan airports, is elevating the risk of mid-air collisions. In addition, the expansion of regional hubs, along with increasing use ofhelicopters in emergency medical service, electronic news gathering, fire control, andparamilitary operations including national security forces is creating higher risk for mid-air collisions.

Pilots Responsibility to See and Avoid

Critical to safe flight is the accurate and timely pilot awareness of potential threat aircraft.Combining visual and aural alerts provides a higher degree of accurate decision makingin high workload situations within the modern flight deck. Dependence on ATC does not

guarantee separation. Responsibility for collision avoidance rests solely with the pilot incommand (PIC).

Federal Aviation Regulations (FAR 91.113) states:When weather conditions permit, regardless of whether an operation is conducted underinstrument or visual flight rules, vigilance shall be maintained by each person operatingan aircraft so as to see and avoid other aircraft.

Understanding the PIC and the Air Traffic Controller (ATC) responsibility is also criticalas detailed inAirmans Information Manual (AIM) Section 5-5-8 and Section 5-5-10:

See and Avoid

Pilot1. When meteorological condition permit, regardless of type of flight plan or whether ornot under the control of the radar facility, the pilot is responsible to see and avoid othertraffic, terrain, or obstacles.

Controller1. Provides radar traffic information to radar identified aircraft operating outside positivecontrol airspace on a workload permitting basis.

2. Issues safety alerts to aircraft under their control if aware the aircraft is at an altitudebelieved to place the aircraft in unsafe proximity to terrain, obstructions, or other aircraft.

Traff ic Advisories (Traff ic Inform ation)

Pilot1. Acknowledges receipt of traffic advisories2. Informs controller if traffic in sight3. Advises ATC if a vector to avoid traffic is desired4. Does not expect to receive radar traffic advisories on all traffic. Some traffic may notappear o the radar display. Be aware that the controller may be occupied with higher

priority duties and unable to issue traffic information for a variety of reasons.5. Advises controller if service is not desired.

Controller

1. Issues radar traffic to the maximum extent consistent with high priority duties except inClass A Airspace.2. Provides vectors to assist aircraft to avoid observed traffic when requested by the

pilot.3. Issues traffic information to aircraft in the Class B, Class C, Class D surface areas forsequencing purposes.

Clearly, the PIC is solely responsible for collision avoidance.

A Review of Statistical Data on Mid Air Collisions

A recent review1 of accident statistical data suggests that

1. On average, NASA receives 577 pilot reports of near in-flight collisions each year. 12. On average, there are 15.6 midair collisions each year in US civil aviation. 1

3. Private pilots on VFR flights spend about 50% of their time on outside traffic scanduring cruise, and only 40% during arrival & departuremeaning VFR pilots arespending 50%-60% of their time with their heads down! 1

4. The risk of traffic conflicts are actually greatest between a fast moving and a slowmoving aircraft.

5. Failure to see and avoid is cited as the probable cause for 94% of all in flightcollisions. 1

Equally compelling is that in several mid-air accidents, the NTSB determined that theprobable cause was the inherent limitations of the see and avoid concept, andunderscoring the need for low-cost proximity warning and conflict detection systems.

Researchers with the U.S. Department of Defense found that, the second leading causeof death in military helicopters is mid-air collisions, after CFIT. In this study,researchers specifically stated that TSO C147-certified Traffic Awareness Systems(TAS) provide the best technology and are the least expensive option for preventionof mid-airs. 2

Advisory Circular 90-48C suggests that the total time required by a pilot to identify anapproaching aircraft, recognize a collision course, decide on action, execute that action,and allow the aircraft to respond as around 12.5 seconds. (TAS systems provide a hugebenefit with up to 30 seconds of warning time, more than twice the time required).

An MIT-Lincoln Lab study3 showed that VFR pilots given a TCAS-type traffic advisory

were able to visually acquire traffic 85% of the time, compared with 56% when no trafficadvisory was available. And thats in severe-clear VFR. (Of course, the presence of atraffic display allows pilots to see transponder-equipped traffic virtually 100% of thetime on their display). This study concluded that the ability of pilots to visually detectaircraft on near-collision courses is not great, and suggested that [See & Avoid] is adangerously flawed method for separating high- and low-performance aircraft.

Mitigation strategies include having reliable altitude encoding transponders activated atall times on all aircraft, and affordable and reliable collision avoidance technologies in allgeneral aviation aircraft, as the NTSB recommended in 1987.

Its clear that todays on-board traffic avoidance systems -- which have become more

and more affordable -- provide you with a second set of eyes in the cockpit for theadded measure of safety you need in todays busy airspace.

Traffic Collision Avoidance System (TCAS)

TCAS is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions between aircraft. It monitors the airspace around an aircraft for other aircraftequipped with an active transponder--independent ofair traffic control--and warns pilotsof the presence of other transponder-equipped aircraft which may present a threatofmid-air collision. By interrogating their transponders, it analyzes the replies todetermine range, bearing, and if reporting altitude, the relative altitude of the intruder.Should the TCAS system determine that a possible collision hazard exists, it issuesvisual and audio advisories to the crew for appropriate vertical avoidance maneuvers.

TCAS II is designed for Air Transport category and larger corporate jet aircraft. TCAS IIissues a Traffic Advisory (TA), Traffic, Traffic, in the event that an intruder aircraftcomes within 35-40 seconds of imminent collision, and pilots are instructed to maintainvisual separation from the traffic. In the event the intruder traffic closes within 20-30seconds of imminent collision, TCAS II issues a Resolution Advisory (RA), such asClimb, Climb Descend, Descend or Monitor Vertical Speed. The desired climb rate

directed by the RA is typically displayed on a RA/IVSI (Vertical Speed Indicator) that ispart of the TCAS II system.

TCAS I is a relatively lower-cost traffic avoidance system designed for Turboprop andlight get aircraft. TCAS I monitors the traffic situation around the host airplane and offersinformation on the approximate bearing and altitude of other aircraft , and issues a TATraffic, Traffic in the event that an intruder aircraft comes within 30-45 seconds ofimminent collision. The TA warns the pilot that another aircraft is in near vicinity, butdoes not offer any suggested remedy; it is up to the pilot to decide what to do, usuallywith the assistance of Air Traffic Control.

TCAS II Active interrogating system issuing traffic alerts (TA) and resolutionadvisories (RA) Meets TSO C119

Traffic Advisory System (TAS)

Traffic Advisory Systems (TAS) are a lower cost version of TCAS I that were designedfor general aviation aircraft. Just as with TCAS I, TAS systems actively interrogate othernearby aircraft and provide Traffic Advisories (TA) in the event that an intruder aircraft iswithin 30 seconds of imminent collision.

The four most popular TAS systems available for general aviation aircraft are theAvidynes TAS600 Series, the Garmin GTS800 Series, the L3 Skywatch systems, andHoneywells KTA-870 system. Each of these systems is designed to meet theperformance guidelines of TSO-C147. These systems detect intruder aircraft based onfor traffic advisory systems.

TAS systems include a main Processor and either a top and bottom antennaconfiguration (TAS600, GTS8XX, and KTA-870) or single top-only antenna set-up(Skywatch). It is worth noting that all TCAS I and TCAS II systems utilize top and bottomantennas for optimum traffic coverage and minimal shadowing effects of the fuselage.

Meets FAA TSO-C147 specificationsNot dependent on third party interrogationActively Interrogates threat aircraft transponders for reply Provides real-time collision alerts Provides up to a 30-second warning at up to 1200 knot closure(same as TCAS I)

Traffic Information Services (TIS)

TIS is a request/response technology providing passive datalinked information to aircraftequipped with early versions of Mode S transponder to receive ground based broadcastof nearby potential threat traffic.

Traffic Information Service (TIS) was designed to provide information to the cockpit viaground based data link. TIS was intended to improve the safety and efficiency of "seeand avoid" flight through a display that informs the pilot of nearby traffic and potentialconflict situations. It was explicitly explained that TIS was NOT intended to be used as acollision avoidance system per se, and does not relieve the pilot responsibility to "seeand avoid" other aircraft.

TIS service was provided by the terminal Mode S systems that were paired with ASR-8/9digital primary radars. These systems, many of which are now being phased out, wereinstalled in locations with high-density traffic. Theoretically, the service was availablewithin 55 NM of the sites. This maximum range varied greatly by radar site and wasalways subject to "line of sight" limitations, making it unavailable when flying near the"floor" of radar coverage and at low altitudes in many areas of the country, particularly inmountainous regions. Because TIS used ground-based radar, the accuracy of TIS datawas dependent on the distance from the radar providing the service. At longer distancesfrom the radar, TIS cannot accurately determine relative bearing/distance information onintruder aircraft that are in close proximity.

In April, 2005, the Federal Aviation Administration (FAA) issued a decision paper,Discontinuation of Mode S Traffic Information Service (TIS) at Sites Where ASR-7/8Radars Are Replaced by ASR-11. In the paper, the FAA stated that the safety benefits ofTIS did not warrant the cost to continue providing the services at 23 sites slated for the

ASR 11 upgrade as part of the ADS-B Next Gen program. This reduction plan would

eliminate TIS coverage from 107 radar sites to 84 by 2012.

Essentially, TIS is being phased out in favor of ADS-B.

TIS Overview Utilizes Mode-S transponders only (TIS not available outside continental US) Datalink information received from select Approach Radar facilities only Available within 55nm of Terminal Mode S Radar Sites Not available on enroute radars Information susceptible to data loss due to line-of-sight reception Information delayed 5-15 seconds based on radar interrogation sweep Not intended specifically for use as collision avoidance

ADS-B Out equipment mandated in US by January 1, 2020

ADS-B, which consists of two different services, ADSB Out and ADSB In, is designedto replace radar as the primary surveillance method for controlling aircraft worldwide. Inthe United States, ADS-B is an integral component of the NextGen National Airspacestrategy for upgrading/enhancing aviation infrastructure and operations.

ADS-B Out equipment is mandated in the U.S. by January 1, 2020 for all aircraftoperating in Class A, B, and C airspace, or in Class E airspace areas at or above 10,000feet MSL over the 48 contiguous United States and the District of Columbia, excludingthe airspace at and below 2,500 feet above the surface.

There is currently no mandate for ADS-B In.

While we are several years away from needing to comply with the mandates, it iscomforting to know that all Avidyne TAS600 Series Active Surveillance Traffic Systemsare fully upgradeable to ADS-B In.

Choosing a Traffic System

When Choosing a Traffic System for your aircraft, safety is the foremost concern. Youwill also be considering price, functionality, weight, installation costs, and upgradeability.

TAS provides the best value for General Aviation aircraft. Just as with TCAS, TASsystems are transponder based. If a nearby aircraft has a transponder that is notfunctioning or is in the OFF position, then the TCAS/ TAS system will not detect thethreat aircraft.

Non-Threat Other Traffic (OT)Open White (or Cyan) DiamondAltitude is greater than 1200 feetDistance is beyond 6 nm range, not yet a threat

Arrow denotes climb (or descent) of 500 feet per minute orgreater

Proximity Alert (PA)Filled White (or Cyan) DiamondAltitude is within 1200 feetDistance within 6 nm range, not yet a threat

Arrow denotes climb (or descent) of 500 feet per minute orgreater

Traffic Alert (TA) TAS (& TCAS I)TA is indicated as a yellow circleTraffic with calculated intercept course for altitude anddirection becomes a TAAutomated voice alert based on time to closure rateTA maximum alert is 30 seconds for TCAS I and TAS, 45

Seconds for TCAS IITA not available with TIS

TAS and TCAS I systems provide three levels of alert. The first level of alert is indicatedon the display as an open diamond shape, with the altitude separation indicatedbetween the host and threat aircraft and an arrow indicating if the threat aircraft isclimbing, descending, or at the same altitude. This is referred to as Other Traffic (OT).OT is not an immediate threat but is within the surveillance area and the pilot should beaware of existing traffic.

The second level is the Proximity Alert (PA) which is displayed with the same informationas OT, with the exception that the diamond is now a solid shape on the traffic display.

Both OT and PA alerts are typically cyan on a color display or white on a monochromaticdisplay.

The third level is the Traffic Alert or TA. Traffic with a calculated intercept course foraltitude and direction become a TA. When a TA is encountered, the intruder traffic isindicated as a yellow circle. The pilot is also alerted by an automated voice alert thatsays Traffic! Traffic! or Avidynes Heads-Up Audible Position Alerting announces thethreat traffics clock position, relative altitude and distance. The alert is based on time toclosure rate. The maximum alert is 30 seconds at a maximum 1200-knot closure, whichcalculates to a ten-mile distance.


17/27

If the target aircraft is higher than your altitude, its relative altitude will be displayedabove the target with a plus sign (+02 = 200ft above) and if lower, with a minus signbelow the target. A direction arrow next to the target indicates that the target is eitherclimbing or descending at a rate of 500FPM or greater.

TCAS II provides a similar level of alerts as TAS and TCAS I with the addition ofResolution Advisory or RA. When the TCAS II system detects an imminent interceptcourse, the intruder aircraft is displayed as a red square and the pilot is audiblyinstructed to Climb or Descend and visually directed by the RA/IVSI display with theappropriate vertical speed needed to avert a collision. Both aircraft must be equippedwith TCAS II systems to experience an RA.

Dual-Antenna TAS600 System

Safety is the foremost concern when choosing a traffic system for your aircraft. Otherconcerns include price, functionality, and installation costs. In the next few pages we will

clearly show you why Avidynes TAS600 Series are the most safe and economical TASsystems on the market today.

Avidynes TAS600 family of Traffic Advisory Systems (TAS) brings affordable active-interrogation collision avoidance to a wide variety of general aviation aircraft. All TAS600systems include Avidyne-exclusive features and Ryan Active Surveillance (RAS)technology.

With the TAS600 Series, Avidyne brings affordable active-interrogation collision avoidance to a wide variety of generalaviation aircraft, they are the smallest, lightest, mostaffordable, and best-performing TAS systems on the

market today. In addition, the TAS600s dual-antennaarchitecture is fully upgradeable for ADS-B IN.

Three basic components make up the TCAS/TAS systems. The first component is theAntenna system; the second is the Processor; and the third component is the instrumentpanel Display.

The TAS600, TAS605, TAS615, and TAS620 are designed to meet the specific needs ofeach class of aircraft. Each is designed to provide a full 30-second decision time at aclosure rate of up to 1200 knots, just like TCAS I. TAS600-series traffic systemsinterrogate transponders from nearby aircraft within their respective coverage volume(shown above), and provide a warning to the flight crew when the calculated time toclosest approach (CPA) of any intruder and the protected area around the aircraftreaches the 30-second threshold.

When the FAA evaluated the TAS during initial TSO certification trials in the LA valley,they stated that it is obvious that within the cone of interest, the Avidyne system isperforming far in excess of the Advisory Circular requirement.

Patented Top and Bottom Antennas

Like the dual-antenna architecture of more expensive TCAS systems used in Airlinersand Corporate jets, Avidynes top and bottom directional antennas interrogate andreceive replies from threat aircraft transponders above and below the aircraft. This dual-antenna architecture is designed to minimize surveillance interference from your ownairframe.

The top antenna provides directional surveillance to the front and aft on the aircraft. Thebottom antenna provides directional surveillance to the left and right of the aircraft.Thisdual-antenna architecture provides greater accuracy for range and bearing resolution ofintruder aircraft.

Advantages of Dual Antenna systemSingle-antenna systemsThe interrogation signals from single-antenna systems may not alwaysreceive replies due to airframe

shadowing, or they can miss repliesfrom aircraft beneath the hostaircraft.

Patented Top & Bottom AntennasAvidynes TAS600 sends outinterrogation pulses and listens forreplies from other aircraft 360around the host aircraft.

Avidynes Heads-Up Audible Position AlertingSafety is not limited to visual interpretation, which is why Heads-Up Audible Position

Alerting is incorporated into all TAS600 Series systems. Heads-Up Audible PositionAlerting provides ATC-like callouts of intruding traffic, annunciating the threat alertincluding clock position, relative vertical position and distance of any threat aircraft withinthe surveillance envelope, thus reducing visual overload. With Heads Up Audible

Position Alerting, the TAS600 clearly alerts the pilot to an imminent threat:

Traffic, One Oclock! High! Three Miles

The TAS600 Series eliminates the added step of acquiring intruder aircraft on a displayand then visually locating the threat. With the TAS600 Series, you can now simply,HEAR AND ACQUIRE.

Active InterrogationAll TAS600 systems search the sky in real-time in any radar or non-radar environment.The interrogation of ATC, military radar, and other active collision avoidance systems iscontinuously sent up to 56 times per second by the TAS600 and can receive replies from

Mode A, C, or S transponders.

The TAS600, TAS605, TAS615 and TAS620 are designed to meet the specific needs ofeach class of aircraft, providing a full 30-second decision time at a closure rate of up to1200 knots. TAS600 series traffic systems interrogate transponders from nearby aircraftwithin their respective coverage volume, and provide a warning to the flight crew whenthe calculated time to closest approach (CPA) of any intruder and the protected areaaround the aircraft reaches the 30-second threshold.

TAS600 - ADS-B UpgradeabilityAll TAS600 systems are upgradeable to TAS600A, which adds ADS-B In. Capability.

Avidyne TAS600-Series Features & Functions:

Ground ModeGround Mode enables the system to ignore traffic on the ground and mute audioannouncement while displaying traffic more than two hundred feet above the groundeliminating nuisance alerts. This feature is important as the aircraft taxis out, especially

at uncontrolled airports. The Weight on Wheels mode will automatically enable anddisable Ground Mode.

Approach ModeThe Approach Mode, when engaged, permits the TAS600 Series to ignore traffic on theground during the approach phase of a flight eliminating nuisance alerts. At times thepilot may desire to see traffic during approach, with this in mind, the system wasengineered as a pilot selectable option.

Weight on WheelsThis is a discrete input which automatically switches the TAS600 system into GroundMode upon landing, minimizing any distraction from ground traffic. Traffic above the host

aircraft is still shown on the multifunction display, without audio warnings. This alsoallows for continued situational awareness when preparing for departure.

Audio Yoke-Mounted Mute and Volume ControlThe TAS600 Series is the only TAS system available with an audio volume controlenabling the announcement to be heard by the pilot and crew but not necessarily heardby passengers. Also available is a yoke-mounted mute button which allows the systemto be muted when needed. If another Traffic Alert (TA) is detected, the TAS600 systemwill automatically disengage the mute and announce the threat and updated intruderposition.

N-Number Capability

Mode S transponder-equipped aircraft have the ability to transmit their N-number, whichcan be decoded by the TAS600 system. This number can be viewed on compatiblemultifunction displays when interfaced to the TAS600 via its RS232 data bus output.

Most Display OptionsThe TAS600 Series provides industry-standard ARINC 429 and RS232 display outputsand has the most display options available for TAS systems. With interfaces to thedisplays of over 15 popular display manufacturers, including Avidynes Entegra & R9,EX600 and EX5000, Aspen EFDs, Garmin GTN and GNS Series, G500/600 andG900/1000, its a pretty safe bet that the TAS600 can connect to your display with ease.

Why should I install a traffic system on my airplane?The most feared of all flying incidents is the mid-air collision. Even when we are vigilantin our See and Avoid technique, we fear what we cant control; the occurrence of theother guy who might not be as diligent as us. Perhaps the fear is out of proportion to theactual threat, but nonetheless it is regarded one of deadliest flying hazards.

Its obvious that mid-airs happen when they are least expected. The pilots responsibilityis to visually scan for traffic, and even the best set of eyes can miss a fast-movingapproaching aircraft. This presents a real need for a traffic advisory system. Throughoutthe years, statistics have proven that these systems have decreased the total number ofmid-air collisions.
