Definition
A long, gently angled taxiway exit from a runway, designed to allow landing aircraft to leave the runway at a higher speed than a standard 90-degree turnoff. This shortens runway occupancy time and increases airport capacity.
Plain English
A taxiway that branches off the runway at a shallow angle, so an aircraft that has just landed can turn off without slowing all the way down first.
Context Anchor
Seen on airport diagrams, runway exit planning, landing roll discussions, and ATC instructions after landing.
Why Pilots Care
Reduces runway occupancy time, increases airport throughput, and lowers the chance of runway incursions or go-arounds behind slower traffic.
Analogy
It is like a highway exit ramp with a gentle curve instead of a sharp corner. The shape lets you leave the main path smoothly without slowing as much.
Intuition Check
High speed does not mean the pilot should take the turn as fast as possible. It means the exit is designed so an aircraft can safely leave the runway at a higher speed than on a sharper exit.
Example Sentence 1
Tower asked if we could make the high speed turnoff at Bravo, and we accepted to keep the following traffic from going around.
Example Sentence 2
The airport diagram shows three high-speed turnoffs on the longer runway, each marked with a yellow sign and leading directly to the parallel taxiway.
