Definition
An airport with an operating air traffic control (ATC) tower, where pilots must establish two-way radio communication with the tower controller and receive clearances or instructions before taxiing, taking off, or landing within the tower's airspace.
Plain English
An airport that has a control tower with controllers on duty. Pilots have to talk to the tower on the radio and get permission before moving on the runway, taking off, or landing.
Context Anchor
You will see this term when preparing to taxi, take off, or land at an airport where a control tower is open and directing traffic.
Derivation
Tower comes from the idea of a tall structure used to see over an area. In aviation, the control tower is the place where controllers watch and direct airport traffic. Towered means the airport is served by that operating tower.
Why Pilots Care
Requires specific radio procedures, clearances, and adherence to ATC instructions rather than self-announced intentions.
Intuition Check
Do not assume towered only means there is a tower building on the airport. For pilot operations, it means the control tower is operating and controlling traffic at that time.
Example Sentence 1
Before entering the Class D airspace around the towered airport, the student called the tower and received clearance to enter the left downwind for runway 27.
Example Sentence 2
At the towered airport the student waited for takeoff clearance before advancing the throttle.
