In the context of the European Commission's SESAR initiative, the C-ATM prototype has been built in order to investigate aspects of the TTA (Target Time of Arrival) concept outlined in the C-ATM OSED (CATM-WP113-ERC-OSED-D113-V0110)
Current features of the C-ATM prototype are:
- One TTA point may be defined at a waypoint in the arrival segment of a flight.
- For each flight where a TTA is defined, the initial flight-plan, including the STAR and destination airport, are loaded into the aircraft 30 mins before entry into the simulation.
- A pseudo FMS calculates the estimated time at the TTA point and attempts to meet the time by varying aircraft speed using an algorithm that makes the updates more reactive as the aircraft approaches the destination airport.
- The status of the aircraft's ability to meet the TTA is downlinked via ADSB, together with an alert if the time falls outside of a pre-defined window.
- An LTM (Local Traffic Manager) window displays the TTA status of all the aircraft in the simulation.
- The pilot or the LTM may request that the TTA be changed, and specify a new value.
- In each CWP, an LTM Message Window keeps the ATC Controllers informed of messages passing between the GROUND and AIR systems.
- NAVSTART scripted orders may be programmed to make the aircraft enter the simulation earlier or later than the planned time, in order to simulate early or late take-offs
