Definition
A notation on an instrument approach chart indicating that a procedure turn (course reversal) is not authorized when the aircraft arrives at the initial approach fix from a charted route or radial that already aligns it with the final approach course. When 'No PT' is depicted, the pilot must proceed straight in without performing a course reversal unless specifically cleared otherwise by ATC.
Plain English
It means: don't fly the turn-around maneuver here. You're already lined up with the runway approach, so just continue straight in.
Context Anchor
Seen on instrument approach charts, especially near feeder routes, initial approach segments, and course-reversal areas.
Derivation
No PT is shortened from “No Procedure Turn.” “PT” is the common chart abbreviation for procedure turn, and “No” tells the pilot that this turn is not to be flown on that route.
Why Pilots Care
It prevents unnecessary maneuvering that could take the aircraft outside protected airspace or interfere with traffic flow.
Intuition Check
Do not read No PT as “the procedure turn is optional.” In this context, it means the procedure turn is not to be flown on that segment unless ATC gives different instructions.
Example Sentence 1
The arrival from the VOR was marked 'No PT,' so the crew flew straight to the final approach fix without a course reversal.
Example Sentence 2
ATC cleared us for the approach with No PT noted on the plate so no course reversal was performed.
