For aircraft categories C, D, and E, how long is the timing for the 45 straight leg of the ICAO 45/180 Procedure Turn?

The 45/180 Procedure Turn is a maneuver used to change the direction of flight typically in the context of instrument approaches. For categories C, D, and E aircraft, the timing for the 45-degree leg of the turn is specifically standardized for the execution of the procedure.

For these aircraft categories, the standard timing for the straight leg of the procedure turn is set at 1 minute 15 seconds. This time frame is designed to account for the higher speeds at which aircraft in these categories typically operate, allowing for a safe and efficient turn to maintain the intended flight path.

Understanding this timing is critical to ensuring proper separation from other aircraft, maintaining situational awareness, and successfully completing the procedure turn without deviating from the planned path. This timing helps ensure uniformity and predictability during operations in busy airspace, especially during approaches where coordination with air traffic control is crucial.
