L-3Harris has released a document that lists business jet models that carry the required equipment for participation in U.S. domestic en route controller-pilot data link communication (CPDLC) trials. According to a Honeywell briefing on this subject, the FAA will temporarily exclude aircraft that don’t meet the equipment requirements from the CPDLC trials, but these aircraft will be allowed to participate once their equipment is validated. The excluded aircraft “had a lower than expected transmission success rate,” according to Honeywell.
The list of qualified business aircraft includes the Gulfstream G280 and G500 through G700; Dassault Falcon 900A/B/C/EX and 8X; Bombardier Global 5000/5500, 6000/6500, and 7500 and Challenger 300/350 and 604/605/650; Embraer Legacy 450/500 and Praetor 500/600; and aircraft with specified Universal Avionics and Garmin G3000/G5000 equipment.
For unqualified aircraft, the FAA and L3Harris, communications service providers, and OEMs are working on identifying and resolving avionics compatibility issues “that are preventing the systems from attaining the desired performance,” Honeywell said.
