1. Operational Considerations for the use of Automatic Dependent Surveillance-Broadcast Non Radar Areas (ADS-B NRA) OST 06-4, 13rd September 2006 Presented by Maria Algar Ruiz (CJAA, Technical Assistant to Operations Director) On behalf of CNS/ATM SG’s chairman CNS/ATM SG

3. SUMMARY  Operational considerations. General Operational Safety Aspects Operations Manual Flight Crew Training  Incident Reporting Minimum Equipment List CNS/ATM SG

4. OPERATIONAL CONSIDERATIONS.GENERAL  The installation A/C must be previously certified. The assumptions in section 5, concerning Air Traffic and Communications Services Providers, and Aeronautical Information Services, should have been satisfied.  A unique ICAO 24 bit aircraft address must be assigned by the responsible authority to each airframe. CNS/ATM SG

5. OPERATIONAL SAFETY ASPECTS  In all cases, flight crews must comply with the surveillance provisions, and relevant procedures contained in the Aeronautical Information Publications (AIP).  Direct controller-pilot VHF voice communications must be available at all times. If flight crew receive equipment indications showing that position being broadcast by the ADS system is in error, they should inform the ANSP, as appropriate, using any published contingency procedures. CNS/ATM SG

6. OPERATIONS MANUAL The Operations Manual subparts B and D will need to be amended to define operational and training procedures for use of the ADS-B-NRA application. The Operations Manual section B should contain the operational aspect described in this guidance material. Operators under ICAO Annex 6 Part II (General Aviation) are not required to have an operations manual. Similar training and operational procedures should be developed and approved by the State of Registry. Sight of this approval may be required by the ADS-B NSP. CNS/ATM SG

7. FLIGHT CREW TRAINING  Aircraft operators should ensure that flight crew are thoroughly familiar with all relevant aspects of ADS-B applications. Flight crew training should address: a) General understanding of ADS-B-NRA operating procedures;b) Specific ADS-B associated phraseology;c) General understanding of the ADS-B technique and technology;d) The characteristics and limitations of the flight deck human-machine interface, including annunciation, controls and methods that will be used in an ADS-B environment;e) The need to use the ICAO defined format for entry of the Aircraft Identification or Aircraft Registration marking as applicable to the flight;f) Operational procedures regarding the transmission of solely the generic emergency flag in cases when the flight crew actually selected a discrete emergency code and SPI;g) Indication of ADS-B transmit capability within the ICAO flight plan but only when the aircraft is certified according to this advisory material;h) Handling of data source errors i) Incident reporting procedures;j) Crew Resources Management and associated human factors issues. CNS/ATM SG

8. INCIDENT REPORTING  Significant incidents associated with ATC surveillance information transmitted by the ADS-B data link that affects or could affect the safe operation of the aircraft will need to be reported in accordance with JAR-OPS 1.420 (or national regulations, as applicable) and to the air traffic services provider and its responsible authority. CNS/ATM SG

9. MINIMUM EQUIPMENT LIST  The MEL will need to be revised to indicate the mandatory carriage of a serviceable system to meet applicable operational requirements for flight in designated airspace. Despatch with partial unserviceability of the system or non-availability of some required aircraft derived data may be permitted in accordance with applicable exemption criteria. CNS/ATM SG
