Missed Approach Point

Missed approach point (MAPt or MAP) is the "point prescribed in each instrument approach at which a missed approach procedure shall be executed if the required visual reference does not exist." It defines the point for precision and non-precision approaches when the missed approach segment of a flight begins provided the runway environment is not in sight. 

A pilot must execute a missed approach if a required visual reference (normally the runway or its environment) is not in sight or the pilot decides it is unsafe to continue with the approach and landing to the runway

The missed approach point is published in the approach plates and contains instructions for missed approach procedures to be executed at this point. 

The missed approach point is normally at the Minimum Descent Altitude (MDA), and may be less than a mile from the runway or several miles out, depending on the conditions related to that particular runway.

The MAP is similar in principle to the Decision Height Point, in that the pilot in command must make a clear and unequivocal Yes/No decision upon arrival at this point - either the runway (or its specified environment) is positively visible and accessible for landing using a safe and stabilized approach (i.e. no excessively steep bank or descent angles required), in which case the approach to landing may be continued, or else the approach must be discontinued and the published missed approach procedure must be initiated immediately.
