Estimate 45/180 procedure turn timing using outbound time and rate of turn. This free aviation calculator helps instrument pilots and students practice timed procedure turns and IFR course reversal planning.
Enter outbound leg time and rate of turn to estimate the timing for a standard 45/180 procedure turn.
This calculator gives a simplified timing estimate for a 45/180 procedure turn and is intended for training and planning awareness.
A procedure turn calculator estimates the timing involved in a common IFR course reversal, especially the 45/180 procedure turn used in instrument training and approach practice.
By combining turn angle and rate of turn with outbound timing, pilots can better understand how long a maneuver may take and build stronger situational awareness during instrument practice.
It is a common course reversal technique where the aircraft turns 45 degrees away from the outbound course, flies for a short outbound segment, and then turns 180 degrees back toward the inbound course.
At a standard rate of 3 degrees per second, a 45 degree turn takes about 15 seconds.
At a standard rate of 3 degrees per second, a 180 degree turn takes about 60 seconds.
No. This calculator is a training and planning aid. Pilots must always follow published instrument procedures, approved training guidance, and current operational instructions.
