Final answer:
In a non-precision approach, a pilot uses a Minimum Descent Altitude (MDA) and not a Decision Height (DH), which is related to a precision approach.
Step-by-step explanation:
When a pilot is flying a non-precision approach, they utilize a Minimum Descent Altitude (MDA). This is the lowest altitude to which descent is authorized on final approach or during circle-to-land maneuvering in the absence of visual references. A Decision Height (DH), on the other hand, is related to a precision approach, where the approach has vertical guidance and the pilot has a clearly defined missed approach point.
Therefore, the correct answer to your question is: b) Minimum Descent Altitude (MDA).
