AOC will respond with Gate ID. Applies to both Trials and Production systems. 3.FAA will send the DCL Courtesy Copy to AOC when actual uplink is sent to pilot. Applies to both Trials and Production systems. 4.ICAO 2012 Flight Plan is a viable mechanism for AOCs to provide clearance delivery information to FAA, e.g., whether a specific flight will get a legacy PDC or DCL. New equipage/preference codes apply to Production system only. Trials will use Remarks field in current flight plan; no change for ICAO 2012 flight plan.
