IS-0303-C — Use of on-board 4D trajectory data to enhance ATM ground system performance: performance based implementation

Dynamic TMR includes the downlink of the trajectory according to criteria depending on the flight phase or portion of the trajectory. This will be supported on the airborne side by e.g. ADS-C EPP provided according to the contract terms which may be dynamically changed during the flight by ANSPs in the context of full 4D operations.
