AIDC safety benefits & limitationsAIDC Implementation Seminar

Introduction Implementation of AIDC
Safety benefits
Data adaptation issues to consider
Limitations
Presentation title
Safety benefits Coordination errors - reduced
Coordinated data should be extracted automatically from flight data processing system
Coordination should occur automatically
Controller workload - reduced Less reliance on intercom/phone lines More time available to complete other tasks
Efficiency - increased Controller can manage increased traffic levels Support DARPs etc
Considerations – Adaptation data What AIDC messages to send?
ABI, EST/ACP; or ABI, CPL/ACP
What about ICD V3 messages such as TRU, FAN, FCN etc
Coordinating changes CDN; or Voice
Will AIDC hand offs be used?
Considerations – Adaptation data When are AIDC messages sent?
Timing parameters When does automation send AIDC messages?
Considerations – Adaptation data Format of Field 14 (Estimate data) supported by neighbouring ATS
Units
Block levels Weather deviations and offsets Mach Number Technique
Needs to be configurable per FIR
Considerations – Adaptation data Content of Field 15 (Route) required by neighbouring ATS Units
full flight planned route; or
route information to commence at the waypoint preceding the coordination point
Should be configurable per FIR
Limitations A benefit of AIDC is it’s automation. However, this can also be a
disadvantage!
Controller is “out of the loop”
What information was coordinated? Unintentional changes to profile (e.g. level) after coordination has
occurred Automatic updates to profile (e.g. estimates) without controller
awareness (e.g. ADS-C estimate updates)
Limitations Processing AIDC messaging for short term FIR transits
ATSU 2ATSU 1
MINNY
DONLD
Problems occur when ATSU2 attempts to send AIDC messages to ATSU1 for the entry to ATSU1’s FIR at DONLD, while aircraft is still under the control of ATSU 1
Limitations Duplicate & unknown waypoints, duplicate ATS routes
Cause problems for flight data processing systems All waypoints and routes within the area of responsibility should
be known and unambiguous
Truncation
A means to truncate (delete) unknown route information and allow downstream units to still accurately process AIDC messaging
Must be completed correctly Don’t just delete unknown/duplicate waypoints or routes!
