Definition
A facility located at an airport, staffed by air traffic controllers, that issues instructions and clearances to aircraft operating on the runways, taxiways, and in the airspace immediately surrounding the airport.
Plain English
The tall building at an airport where controllers watch the runways and the nearby sky and tell pilots when and where they can taxi, take off, and land.
Context Anchor
You will encounter this term on airport diagrams, in radio procedures, and when operating at an airport that has an operating tower.
Derivation
From 'control,' meaning to direct or regulate, and 'tower,' a tall structure giving an elevated view. The name reflects its purpose: a raised vantage point from which controllers visually direct traffic on and around the airport.
Why Pilots Care
At a towered airport, pilots cannot taxi, take off, or land without clearance from the tower. Knowing how and when to communicate with it is a basic requirement for legal and safe operation.
Intuition Check
A control tower does not physically control the airplane. It controls the flow of airport traffic by giving instructions and clearances; the pilot still flies the aircraft.
Example Sentence 1
Before taxiing to the runway, the pilot called the control tower for clearance.
Example Sentence 2
During the approach, the control tower cleared the aircraft to land on runway 27.
