What does MDA stand for in the context of a non-precision approach?

MDA stands for Minimum Descent Altitude in the context of a non-precision approach. This term refers to the lowest altitude to which a pilot can descend during the approach phase of a flight before they must have the runway in sight or execute a missed approach. The MDA is established to ensure that the aircraft remains safely above obstacles in the area while providing the pilot with enough altitude to make safe decisions regarding landing or continuing the approach.

Understanding the role of MDA is crucial for pilots flying non-precision approaches, as it helps them establish a safe and controlled descent while navigating through potentially hazardous terrain and obstacles. The significance of this altitude in the aviation community emphasizes the importance of situational awareness during approaches and landings, particularly in lower visibility conditions.

In contrast, the other options refer to concepts that either do not exist or are not relevant in this context, as they deviate from the definition and purpose of the Minimum Descent Altitude utilized in non-precision approaches.
