Use controller-pilot data link and ADS-C over the ocean and in foreign airspace. We prepare your A056 package, including the monitoring and reporting procedures the FAA expects.
CPDLC (controller-pilot data link communications) lets pilots and controllers exchange clearances and requests as text messages instead of HF voice. ADS-C (automatic dependent surveillance — contract) sends the aircraft’s position to ATC automatically.
Together they allow reduced separation, better routes, and fewer position reports. They are required for much of the North Atlantic and are used across the Pacific and in Europe.
It depends on where you use it.
Part 91 operators do not need an LOA to use U.S. domestic departure clearances (DCL) or en route CPDLC.
Crossing the North Atlantic? Data link usually goes with NAT HLA and RVSM. Our International Ops Package handles them together.
AFM supplement or manufacturer statement showing FANS 1/A (or ATN) capability, subnetworks, and performance.
Data link messages recorded as required by §91.609(j), and data link equipment covered in the MEL.
Normal, abnormal, and emergency CPDLC and ADS-C procedures, plus the latency timer statement.
A monitoring process, problem reporting to the monitoring agency, and demonstrated performance results.
We see these delays over and over. We check for every one of them before anything goes to the FSDO.
The flight ID used for logon must exactly match the filed flight plan.
PBCS codes go on the flight plan only when the aircraft and LOA are authorized for PBCS.
Inspectors ask for evidence the CVR records data link messages.
Data link equipment must be addressed in the MEL or MMEL before approval.
The FAA expects a written process for monitoring performance and reporting problems.
LOAs belong to the operator. A sale means a new application.
No. Part 91 operators can use U.S. domestic DCL and en route CPDLC without an LOA. A056 is for oceanic, remote, and foreign airspace that requires approval.
Aircraft flying FL290 to FL410 in most of the North Atlantic must have working CPDLC and ADS-C, unless they fly in exempted airspace or hold a published exemption.
PBCS is authorized as part of A056 when the aircraft meets RCP 240 and RSP 180. We can include it in your package if your aircraft qualifies.
Yes. A056 covers ATN data link (formerly Link 2000+) used in European airspace as well as FANS over the ocean.
