Use cases and requirements

Transmission interval Performance criteria.

Transmission technologies VHF, satellite. The protocols are typically ACARS, satellite communication (SatCom) and IP based.

4.4 Ground movement/handling

Since the ATC functions include the separation of incoming and outgoing traffic from an aerodrome, there are
almost the same parameters for ground movement/handling.

Description Provide real-time instantaneous aircraft departure, arrival and en-route information (tam-
per-proof collection of flight data) to ATC.

Scenario The ground controllers use the data from the aircraft to monitor and manage the activities
and movements on the ground.

User groups • AOC;
• ATC.
Benefit • Increase in A/C safety;
• High reliability for A/C dispatch;
• Accurate aircraft information.
Required data • Position reports;
• Any data that contains aircraft out, off, on, in (OOOI) times.
Data sources • FMC;
• DFDR;
• AOC reports.

Special considerations Data security, integrity and reliability.
Amount of data Very nominal payload.

4.5 Trouble-shooting

Description Collect, analyse and store aircraft systems (tamper-proof collection of flight data), engines
data for detection of degradation. The reliability of an A/C can be significantly increased by
detection and replacement of attired parts.

Scenario Trouble-shooting is an activity from the line maintenance to solve technical aircraft problems
that are not directly covert in the aircraft mechanics procedures. The pertinent data from
CMC, ACMS, maintenance panel and related avionics equipment that generate BITE can be
acquired. The BITE status can be then transmitted for trouble-shooting. Obtaining the per-
formance data and BITE data during the flight gives a time advantage. Spare parts and tools
can be prepared before the aircraft is on ground. The time to fix the problem and release the
aircraft back to service gets significantly shortened.
User groups • Maintenance;
• MRO.

Benefit • Increase in A/C safety;
• High reliability for A/C dispatch;
• Accurate aircraft information.
