How do I change the MTT (minimum turnaround time)?

If an aircraft type has no critical path of its own, AGOA uses the default critical path and its MTT. Change the MTT in the critical path, in a specific critical path for some routes, or with a special operation on a single turnaround.

The MTT (Minimum Turnaround Time, also called TTM) is set in the critical path of each aircraft type. How you change it depends on which flights the new MTT should apply to.

Why is the MTT wrong for my aircraft type?

Each critical path is set up for one aircraft type, airline and airport, with its own MTT. For each airline and airport, one critical path is marked as the default aircraft. If a flight operates with an aircraft type that has no critical path of its own at that airport, AGOA uses the default critical path, with its MTT and its tasks.

To check it:

  1. In the Backoffice, open Critical Path.

  2. Look for the airline and airport of the flight. The Default Aircraft column shows which critical path is the default one (✓).

  3. Check whether the aircraft type of the flight has its own critical path. Check the exact variant (for example, 789 or 78X).

If the aircraft type has no critical path of its own, create one with the right MTT. See How do I set up a critical path for another aircraft type? Don't change the MTT of the default critical path: it would change it for every aircraft type that uses it.

To choose which critical path is the default one, open it in the Backoffice and turn on the Default toggle in the Aircraft section.

1. For all flights of an aircraft type

You need the Critical Paths permission in Editor.

  1. In the Backoffice, open Critical Path.

  2. Open the critical path of the aircraft type.

  3. In the Aircraft section, change the MTT (HH:mm).

  4. Adjust the target times (A+ and D-) of the tasks that need it, for example boarding, cleaning or deboarding, so they fit the new MTT.

  5. Save your changes.

Important: the new MTT applies to all turnarounds that use this critical path, including turnarounds already created. If it should only apply to some flights, use option 2 instead.

2. For some routes or flights only

For example, a transit flight, international flights, or flights from a specific airport. Create a specific critical path based on the existing one, set the origin and destination it applies to, and change its MTT. The other flights keep the MTT of the original critical path. See What is a specific critical path?

3. For a single turnaround (special operations)

Special operations are toggles that adapt one turnaround to a particular situation. Some of them, such as Crew Change, add time to the MTT of that turnaround only. A user with the Special operations permission in Editor can turn them on:

  1. In AGOA, open the turnaround.

  2. Under the departure times, turn on the toggle of the special operation (for example, Crew Change).

If you don't see the toggle, update the AGOA app to the latest version. Special operations are set up in the Backoffice. See What are special operations, and how do I use them?

If you don't have the permissions needed, ask an administrator in your company. If nobody in your company has access, contact our support team at [email protected] with the airport, airline, aircraft type and the new MTT.
