What is Taxi-Out Time?

The Taxi-Out Time is computed as the duration between gate out time and take off (wheels off) time. A system value is obtained by averaging these durations over a period of time.

Taxi-Out Time: Terminology

Airport Collaborative Decision-Making (A-CDM) specifies different terms for Taxi-Out Time:

• Estimated Taxi-Out Time (EXOT): The estimated taxi time between off-block and take off.
• Actual Taxi-Out Time (AXOT): The time period between the Actual Off-Block Time (AOBT) and the Actual Take Off Time (ATOT).
