If your aircraft arrives late but you still have time to depart on time, i.e. the time between ATA and the STD is greater than your MTT, then nothing happens: the aircraft is still supposed to leave at the STD.
If you aircraft arrives so late that you do not have time to leave on time, i.e. the time between your ATA and the STD is shorter than your MTT, then AGOA will calculate a Projected Time of Departure (PTD) as: PTD = ATA + MTT. It is supposed to represent the soonest the aircraft will be ready to depart.
On top of this, tasks are related to either the arrival or the departure, and their timings therefore recalculate depending on the ATA and the PTD when there is one.
Example: Flight with STA 11:00 and STD 13:00
- Disembark Pax has a start reference of A+00:02, and the aircraft arrives at
ATA = 11:23. Regardless of what was scheduled, the theoretical start time of Disembark Pax will be 11:25. - Boarding has a start reference of
D-00:30, and the MTT of the aircraft is 2h00. Regardless of what was scheduled, the PTD will therefore be 13:23 and the Boarding task will be supposed to begin at 12:53.
Your critical path timings will always be respected relatively to the actual time of arrival, so as not to require of your teams to perform a turnaround in a shorter time than given to you. You will always have the MTT to perform all of the necessary tasks.
In case there is an RTD on the flight, the exact same logic as the one described in this article is used, but by replacing STD by RTD.
