Definition
An air traffic control automation tool that calculates and displays recommended runway assignments and sequencing for aircraft on final approach, helping controllers space arrivals efficiently to maximize runway throughput.
Plain English
A computer tool that helps controllers decide the best order and runway for arriving aircraft so traffic flows smoothly into the airport.
Context Anchor
Seen in FAA acronym lists and air traffic control arrival discussions. Pilots may notice its effect through speed instructions, turn instructions, or assigned spacing during arrival.
Derivation
FAST is formed from final approach spacing tool. In this term, final approach means the last part of an approach before landing, spacing means the required gap between aircraft, and tool means an aid used by controllers.
Why Pilots Care
Proper spacing prevents wake turbulence encounters and maintains safe, efficient arrival flows.
Intuition Check
FAST does not mean the aircraft should fly fast. Here, FAST is an abbreviation for a controller tool used to manage spacing on final approach.
Example Sentence 1
Approach control used FAST to sequence the morning arrival rush onto two parallel runways.
Example Sentence 2
Updates from the final approach spacing tool helped maintain consistent intervals during the busy arrival period.
