At what point during a no-gyro PAR approach should you begin to initiate turns?

Initiating turns immediately upon hearing "turn right" or "turn left" is vital during a no-gyro PAR approach because this methodology relies heavily on executing precise and timely turns based on verbal commands from Air Traffic Control (ATC). The no-gyro approach procedure is designed for aircraft equipped without a gyro horizon, meaning that the pilot must rely solely on ATC instructions for directional guidance.

During such an approach, the pilot is expected to react immediately to instructions provided by ATC, which are crucial for maintaining the proper approach path and ensuring safe descent and alignment with the runway. This immediate response helps in accurately tracking the intended flight path, especially since the absence of gyro inputs means the pilot cannot rely on instruments to visually confirm heading changes. Hence, executing turns at the moment of receiving the command ensures adherence to the required flight profile.

In contrast, other options suggest delaying action until various moments in the approach process, which could compromise the timely and safe navigation needed for successful landing during a no-gyro PAR approach.
