Definition
An Airport Traffic Control Tower (ATCT) is an FAA or FAA-contracted facility located at an airport that provides air traffic control services to aircraft operating on the airport surface and within the airport's surrounding airspace, typically out to a defined radius and up to a specified altitude. Controllers in the tower issue clearances and instructions for taxi, takeoff, landing, and movement within the tower's area of responsibility.
Plain English
The control tower at an airport. The people inside it tell pilots when they can taxi, take off, and land, and they keep aircraft separated near the airport.
Context Anchor
Pilots encounter ATCT in airport information, charts, the AIM, and radio communication procedures for tower-controlled airports.
Why Pilots Care
Pilots must contact the ATCT for taxi, takeoff, and landing clearances to maintain safe aircraft separation at busy airports.
Intuition Check
Do not think of ATCT as only the physical tower building. In aviation use, it means the tower facility and the control service it provides.
Example Sentence 1
Before entering the Class D airspace, the pilot contacted the ATCT for landing instructions.
Example Sentence 2
After landing, the aircraft switched to ATCT frequency for ground movement guidance.
