The Taxi-In time is computed as the duration between landing (wheels on) time and gate in time, as reported by carriers. A system value is obtained by averaging these durations over a period of time.

Taxi-In Time: Terminology

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

• Estimated Taxi-In Time (EXIT): The estimated taxi time between landing and in-block.
• Actual Taxi-In Time (AXIT): The time period between the Actual Landing Time (ALDT) and the Actual In-Block Time (AIBT).
