On a non-precision approach, how is the missed approach point determined?

The missed approach point (MAP) on a non-precision approach is determined primarily by timing from the Final Approach Fix (FAF). This method is critical because non-precision approaches lack the precise navigational aids that characterize precision approaches, such as an Instrument Landing System (ILS).

In a non-precision approach, pilots rely on navigational references and timing to ensure they reach the MAP at the appropriate time, allowing them to execute the missed approach procedure safely if they do not see the runway or are otherwise unable to land. The timing typically involves monitoring the aircraft's position and altitude as it approaches the FAF, which serves as a reliable reference point from which to calculate when to initiate a missed approach.

Other methods, such as visual references or following ATC commands, may assist in certain situations but are not standardized for establishing the MAP in a non-precision approach. Similarly, radar guidance might be available in some instances, but it does not play a role in the determination of the MAP in the context of standard non-precision approaches. Therefore, timing from the FAF is the most accurate and recognized method for determining the missed approach point in these scenarios.
