When should you perform the missed approach from the DH or MAP?

The correct approach to the missed approach procedure depends on several critical factors, each serving a significant purpose in ensuring safety during the landing process.

Firstly, if the runway environment is visible and conditions are favorable for landing, continuing to land is appropriate. However, should you not see the runway environment when reaching the Decision Height (DH) or Minimum Descent Altitude (MDA), or if visual cues don’t support a safe landing, you must initiate a missed approach.

Secondly, instructions from the controlling agency take precedence. It is essential to follow directions from Air Traffic Control, as they possess situational awareness and can provide guidance based on real-time conditions that pilots may not be fully aware of.

Lastly, if you determine that a safe landing cannot be made—whether due to weather, obstacles, or other factors—initiating a missed approach is the safe course of action.

All these scenarios highlight the necessity of conducting a missed approach whenever you are facing conditions that do not support a safe landing, thus making the comprehensive answer of all the above relevant and correct. It embodies an understanding of both situational awareness and adherence to procedural protocols, ensuring safety in flight operations.
