GNSS Approach Procedures

What does SBAS give GA?



3,534 WAAS LPV approach procedures at 1725 airports

As of 2nd April 2015


How many SBAS LPV procedures have been established at smaller ‘GA’ airfields with no pre-‐exis4ng IAP?

More than 1500

0 or as near to ZERO as makes no prac4cal difference

PBN Lateral and ver4cal naviga4on

Lateral and ver.cal naviga.on guidance refers to the guidance provided either by: (a) a ground-‐based radio naviga.on aid; or (b) computer-‐generated naviga.on data from ground-‐based, space-‐based, self-‐contained naviga.on aids or a combina.on of these).

11,15

PBN concept (as described in ICAO doc 9613) 11

PBN principles

List the factors used to define RNAV or RNP system performance requirements (accuracy, integrity, con.nuity and func.onality)

21

Explain the concept of con.nuity 21

Explain the concept of integrity 21

State that, unlike conven.onal naviga.on, performance-‐based naviga.on is not sensor specific.

11

Explain the difference between raw data and computed data 200

PBN components

List the components of PBN as NAVAID infrastructure, naviga.on specifica.on and naviga.on applica.on

Iden.fy the components from an example

12 20


PBN scope

State that in oceanic/remote, enroute and terminal phases of flight, PBN is limited to opera.ons with linear lateral performance requirements and .me constraints

11

State that in the approach phases of flight, PBN accommodates both linear and angular laterally guided opera.ons

11

Naviga.on Specifica.ons RNAV and RNP State the difference between RNAV and RNP in terms of the requirement for on-‐board

performance monitoring and aler.ng

10,13

Naviga4on func4onal requirements

List the basic func.onal requirements of RNAV and RNP specifica.ons (con.nuous indica.on of lateral devia.on, distance/bearing to ac.ve waypoint, groundspeed or .me to ac.ve waypoint, naviga.on data storage and failure indica.on)

67


Designa4on of RNP and RNAV specifica4ons

Interpret X in RNAV X or RNP X as the lateral naviga.on accuracy (total system error) in nau.cal miles, which is expected to be achieved at least 95 per cent of the flight .me by the popula.on of aircra\ opera.ng within the airspace, route or procedure.

13

State that aircra\ approved to the more stringent accuracy requirements may not necessarily meet some of the func.onal requirements of the naviga.on specifica.on having a less stringent accuracy requirement.

13

State that RNAV10 and RNP4 are used in the oceanic/remote phase of flight 18

State that RNAV5 is used in the enroute and arrival phase of flight 19

State that RNAV2 and RNP2 are also used as naviga.on specifica.ons 19,18

State that RNP2 is used in the enroute, and oceanic/remote phases of flight 18

State that RNAV1 and RNP1 are used in the arrival and departure phases of flight

19,20

State that RNP APCH is used in the approach phase of flight 14,15

State that RNP AR APCH is used in the approach phase of flight 16,202

State that RNP 0.3 naviga.on specifica.on is used in all phases of flight except for oceanic/remote and final approach, primarily for helicopters
