Estimated time of arrival (ETA) at the handling station
Airway slot time (CTOT or calculated take-off time at origin). If an airway slot is present, the arrival time in the OPS screen will be printed with a W indicator, e.g. 23:00W.
Actual take-off from origin (ATD at origin). If the flight is airborne, the arrival time will be marked with a T for in-Transit, e.g. 23:00T. This is a clue that the aircraft will very likely arrive almost exactly at the given time.
Based on this information, FBO One will calculate the most actual estimated time of arrival, and will update arrival time accordingly in the plan board graph in the Ops screen. Note that FBO One never takes the actual time of arrival (ATA) from CFMU; this value must always be entered by an FBO One end user, typically someone in operations. This is because the CFMU information typically is 20 minutes delayed, and also because the ATA must match the records as kept by the airport authorities in order for any airport fee calculations in FBO One to match the airport's calculations.
For departures, CFMU is queried for:
Flight status, similar as for arrivals.
Estimated time of departure (ETD)
Airway slot time (CTOT or calculated take-off time at the handling station).
This allows operations to see what departure time they must meet.
FBO One will only query for flights that are already entered in FBO One, based on the inbound and outbound flight number. FBO One will not automatically create (prospected) flight handling orders in FBO One based on the CFMU data, so it is important to correctly enter the flight numbers in FBO One for each handling request.
