Definition
A taxiway that exits a runway at an acute angle (typically around 30 degrees) and is designed to allow a landing aircraft to leave the runway at a higher speed than a conventional 90-degree turnoff. The geometry reduces the time the aircraft occupies the runway, increasing airport capacity.
Plain English
A taxiway that branches off the runway at a shallow angle so a landing aircraft can turn off without slowing down as much, clearing the runway sooner for the next arrival or departure.
Context Anchor
Seen during landing rollout at airports with long or busy runways, especially where tower controllers want aircraft to clear the runway quickly.
Why Pilots Care
Reduces runway occupancy time, allowing more aircraft to land per hour and lowering the chance of runway incursions.
Analogy
It works like a highway exit ramp: the curve is gentler than a street corner, so you can leave the main path without slowing as much.
Intuition Check
Do not read “high-speed” as “take the turn fast.” It means the exit is shaped to allow a higher-than-normal runway-exit speed, but the pilot still chooses a safe speed for the aircraft and conditions.
Example Sentence 1
Tower instructed the Boeing 737 to take the high-speed turnoff at taxiway Bravo to expedite clearing the runway.
Example Sentence 2
The airport added high-speed turnoffs at both ends of the main runway to reduce delays during busy periods.
