Which term describes the process of organizing arrival order at the airport?

• A. Mile-in-trail
• B. Traffic reroutes
• C. Ground delay
• D. Sequencing

Answer: (D)

Organizing arrival order at the airport is sequencing. This is the process where air traffic controllers determine which inbound aircraft lands first, second, and so on, so that each arrival fits safely into the runway schedule and spacing requirements. Sequencing takes into account the current traffic mix, weather, and runway availability to create an orderly and efficient flow of landings.

Why this fits best: the term directly describes the act of arranging the order in which planes will arrive and land, rather than describing spacing between planes (mile-in-trail), changing the route (traffic reroutes), or holding aircraft on the ground (ground delay).
