Global Data Link Issues

• Flight plan on file MUST match the registration or the Call

sign when logging on

– Aircraft identification – field 7

– 7 characters (max)

– Aircraft registration number or Call sign

– ICAO designator for aircraft facility followed by the flight ID (N800DW)

– Three letter call sign followed by the flight ID (WDY800) Windy City 800

• Use of the “DCM” call sign (Dot Com) with Fltplan.com

• Flight plan must have the correct equipment codes in fields

10 and 18

Global Data Link Issues

• Flight Crews must use the correct AFN log on code for the ATSU,

after the aircraft enters the CPDLC airspace for that ATSU

• Some FANS systems do require manually entries

– Flight levels

– Forecast winds aloft

– Route changes

• Flying the assigned speed that was cleared by ATC

– Mach Number vs.

– Mach Technique

Global Data Link Issues

• Flight Crews should not enter equal time points into the active

flight plan on the FMS

• Read the entire up link message and use proper CRM to

respond to ATC

• Allow ATC to terminate the data link connection with the aircraft

• Check the ICAO Regional Guides before your flight

• Test the data link system after maintenance or before a flight

into CPDLC airspace

Global Data Link Issues

• Gander Oceanic will soon be using um137 “CONFIRM ASSIGNED ROUTE”

– The correct response is a dm40. Free Text Response is NOT ACCEPTABLE

• CPDLD request for “Position Report” in Canadian Domestic airspace

– MESSAGE IS NOT SUPPORTED

• Data Link Clearance (DCL) at US airports

– Must have “DAT/FANS1P2PDC” in field 18 of your flight plan

– Any free text sent during DCL request will cause the system reject the request

– Tower will “Push” the clearance at P-30 or later depending on tower work load and

conditions

Data Link testing

• Who does Data Link Testing?

– Kobev International and some Data Link Service Providers

• What is Tested ?

– AFN Log On

– CPDLC messages and RCP 240 performance

– ADS-C content and RSP 180 performance

• Where is testing performed?

– Either on the ground or in flight

Who, What, Where, When and Why ?

Data Link testing

• When should a Data Link System be Tested?

– Original Certification Aircraft for STC Approval

– Follow on aircraft for post installation Verification

– In Service Aircraft for post maintenance Verification

– After starting service with a new Data Link Service Provider

– Pre-Flight check prior to entering CPDLC airspace

Who, What, Where, When and Why ?

Data Link testing

• Why should a Data Link System be Tested?

– To verify the installed equipment can perform an AFN Log On

– To verify the CPDLC and ADS-C connections can be established

– To verify the CPDLC and ADS-C (A,L,V,W) interoperability

– To verify the RCP 240 and RSP 180

– To verify the ADS-C content is being transmitted/received correctly

– It verifies that the installation/maintenance was done correctly and the service

provider has set up the data link service correctly as well

– Reduces the risk of potential flight crew violations in the CPDLC airspace

Who, What, Where, When and Why ?

If you have a Sat Phone installed in the cockpit of your aircraft

does this mean you can indicate compliance with:

• M1 SATCOM ATC (INMARST)

• M2 SATCOM ATC (MTSAT)

• M3 SATCOM ATC (IRIDIUM)

in the equipment codes of field 10 or your ICAO flight plan?

YES or NO

12

The answer is….NO.

The installed Satcom voice system must

meet compliance with AC 20-150B and you

must have a Letter Of Authorization (LOA)

to use the system for SATVOICE

communications with Air Traffic Services.

• FANS systems installation or FANS STC’s

• FANS Pilot Training

• FANS system Testing

• LOA assistance
