actual calculated landing time
actual calculated landing time (ACLT)A flight's frozen calculated landing time. This is an actual time determined at a frozen calculated landing time (FCLT) or meter list display interval (MLDI) for the adapted vertex for each arrival aircraft. It is based upon the runway configuration, the airport acceptance rate, the arrival delay period, and other metered arrival aircraft. This time is the vertex time of arrival (VTA) of the aircraft, the tentatively calculated time (TACLT), or the actual calculated landing time of the previous aircraft plus the arrival aircraft interval, whichever is later. This time is not updated in response to the aircraft's progress. The VTA is a calculated time of aircraft arrival over the adapted vertex for the runway configuration in use. This time is calculated via the optimum flight path using adapted speed segments.AcronymsSeeACLT |
