What is MAP in Aviation? (Missed Approach Point)

Updated: March 03, 2024

Understanding the Missed Approach Point (MAP) in Aviation

Aviation is a complex field that operates on a foundation of precise procedures and terminology. One such term is the Missed Approach Point (MAP), which plays a crucial role in ensuring the safety and efficiency of air travel. In this article, we will delve into the concept of the Missed Approach Point, its significance, and its application in aviation operations.

The Missed Approach Point (MAP) Explained

The Missed Approach Point (MAP) is a predetermined point on an instrument approach procedure where a pilot must initiate a missed approach if the required visual references for landing are not established. It serves as a critical decision point for pilots, enabling them to determine whether to continue the approach or abort it and execute a missed approach procedure.

The Missed Approach Point is typically indicated on instrument approach charts, which provide detailed information for pilots to navigate and conduct instrument approaches in low visibility conditions. These charts highlight the MAP by specifying a distance from a navigational aid or a specific geographical point, such as a runway threshold or a fix, where the pilot must initiate the missed approach procedure.

When reaching the Missed Approach Point during an instrument approach, pilots assess their visibility and the position of the aircraft. If they have not established the required visual references, such as the runway environment or approach lights, they must immediately discontinue the approach and execute the missed approach procedure outlined in the approach chart.

Significance of the Missed Approach Point (MAP)

The Missed Approach Point holds significant importance in aviation for several reasons:

Enhancing Safety: By defining a specific point where a pilot must initiate a missed approach, the MAP ensures that pilots have sufficient time and distance to safely discontinue an approach if the required visual references are not established. This helps prevent accidents or incidents that could occur if pilots were to continue their approach without adequate visibility.
Standardization: The Missed Approach Point contributes to standardization in aviation procedures. By providing a consistent reference point for pilots to assess their visibility and make a decision, it promotes uniformity and improves overall safety in instrument approaches.
Efficiency in Airspace Management: The MAP also plays a role in managing airspace efficiently. By allowing pilots to promptly initiate a missed approach when necessary, air traffic controllers can effectively manage the flow of arriving and departing aircraft, minimizing delays and ensuring smooth operations.

Executing the Missed Approach Procedure

When a pilot reaches the Missed Approach Point and decides to initiate a missed approach, they must follow the prescribed procedure outlined in the approach chart. The specifics of the missed approach procedure can vary depending on the airport, runway, and instrument approach being flown.

Typically, the missed approach procedure involves climbing the aircraft to a specified altitude, following a specific track or radial, and complying with any additional instructions provided in the approach chart. This procedure ensures that pilots maintain separation from other aircraft and safely navigate away from the airport environment before proceeding to an alternative course of action, such as holding or diverting to an alternate airport.

It is crucial for pilots to familiarize themselves with the missed approach procedure for each instrument approach they fly, as it varies depending on the specific approach and airport. By studying and practicing these procedures, pilots can effectively handle situations where a missed approach becomes necessary, ensuring the safety of the flight and its occupants.

Aviation authorities, such as the Federal Aviation Administration (FAA) in the United States, regularly review and update approach charts to ensure accuracy and reflect any changes in procedures or navigational aids. Pilots must stay updated with the latest approach charts to ensure they have the most current information regarding the Missed Approach Point and associated procedures.

In conclusion, the Missed Approach Point (MAP) is a critical component of instrument approaches in aviation. It serves as a decision point for pilots, enabling them to determine whether to continue an approach or execute a missed approach procedure if required visual references are not established. By enhancing safety, promoting standardization, and facilitating efficient airspace management, the MAP plays a crucial role in ensuring the smooth and secure operation of air travel.
