Decision Height/Altitude(DH/DA)
Definition
The height during a precision approach at which the pilot must decide to land or execute a missed approach. If the runway environment is not in sight at DH/DA, a go-around is mandatory.
Why Decision Height/Altitude Matters for Pilots
Operational knowledge like Decision Height/Altitude is tested across multiple FAA and EASA exam subjects. Pilots who understand Decision Height/Altitude can operate more safely and efficiently, whether flying light aircraft or commercial airliners. This concept comes up in both written tests and practical checkrides.
Exam Tip
This concept is commonly tested in operations-related questions on FAA and EASA exams. Make sure you can explain Decision Height/Altitude in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
