What does DA stand for?

• A. Decision Altitude
• B. Departure Altitude
• C. Descent Altitude
• D. Determined Altitude

Answer: (A)

On an instrument approach, you reach a specific altitude where you must decide whether you have the required visual cues to land or you must go missed. That point is called Decision Altitude. It marks the threshold at which the pilot must either continue visually to a landing or initiate a missed approach if the runway environment or other required references aren’t in sight. It’s published on the approach plate and is given as altitude above mean sea level, guiding the decision during the final approach phase. The other terms listed aren’t used for this decision point in the same way. Departure Altitude would refer to an altitude related to takeoff, not the landing decision point. Descent Altitude and Determined Altitude aren’t standard terms used to describe the instrument-approach decision point.
