Issue Mis-Use of the CM/CPDLC GAT

• Tool available for Airlines Since Sept 2006
• To exercise CPDLC Independently from a test bed
  or grounded equipped aircraft
• CPDLC familiarization for aircrew
• To check avionics installation
• To verify CMU/ATSU non-regression or new software
  release
• Hosted on the Datalink Test Facility on LFPYTEST
• SUCCESS Story until September 2008 !
• DLH, SAS, RJA, HLX, AZA, BER
• UNTIL . Mis Use Logon in Flight observed ? !!!

8
Issue Mis-Use of the GAT

• Even though the tool is auto-protected against
  mis-understanding
• There is (was) nothing preventing it to be used
  in flight
• The tool was observed to be used in flight, in
  Maastricht airspace or close to it
• Inappropriate Logon to LFPYTEST when EDYY was
  already CDA
• no OPS consequence as the CPDLC connection could
  not established from LFPYTEST (CPDLC-Start
  Rsp-DM107)
• Aircraft with LFPYTEST as CDA when in just before
  entry in Maastricht airspace
• CPDLC connection with EDYY could not be
  established.

9
Issue Mis-Use of the GAT

• Technical implementation of a filter at Logon
  step
• The Logon is accepted only when CallSign
  EEC9999 received
• Better than previous situation, but not optimal
  as some airborne config may allow the initial
  CallSign to be changed in flight.
• Procedural Ask the Airlines to sign a paper in
  which they accept the conditions for using the
  tool

• A Safety analysis was conducted in Nov 2008 with
  three Airlines (those who had been observed using
  the tool in flight)
• Outcome
• The risk is minimum with dedicated CallSign
• The paper is acceptable

10
Issue Mis-Use of the GAT

• TECHNICAL
• Implementation of A Call Sign filter EEC9999 at
  Logon step
• Non sense values in the Uplink Clearances
• PROCEDURAL
• Pre-Requisites for Using the Test Facility
• Document sent to Airlines on the in Dec 08 for
  information and VISA.
