Aircraft Dispatcher Training Center (ADTC) ADX Practice Test

To understand why the correct answer is 8.6 nautical miles (NM) from the ASALT intersection to the Minimum Altitude Point (MAP), it's important to consider the relevant aeronautical navigation principles.

The MAP is a critical point established in the approach procedure, often used by pilots and dispatchers to determine when to execute missed approaches. The distance from an intersection like ASALT to the MAP is usually derived from the formal procedures outlined in the approach charts or other navigational documentation.

For many approach paths, the distance in nautical miles from a predefined waypoint or intersection indicates how far along the procedure an aircraft is in relation to completing the landing phase or preparing to go around. Distances like these are crucial for calculating necessary descent rates, fuel consumption, and timing before landing or executing a missed approach.

The fact that 8.6 NM is chosen indicates that it is based on these navigational calculations and established procedures. Such distances are specific to particular procedures and published in the associated chart for the approach, ensuring pilots and dispatchers are using the most accurate and up-to-date information for safe aircraft operations.

Thus, the distance from ASALT intersection to the MAP being 8.6 NM represents an accurate reflection of the procedure as defined in
