Decision Altitude is used for which type of approaches?

• A. Decision Altitude
• B. Distance Altitude
• C. Descent Altitude
• D. Descent Angle

Answer: (A)

Decision Altitude is used for precision approaches that provide vertical guidance. On approaches like ILS with a glideslope or other procedures with vertical guidance (LPV/VNAV), there is a defined altitude at which you must decide whether to continue the landing or execute a missed approach. If you don’t have the required visual references to land by that altitude, you must go around. Non-precision approaches don’t provide vertical guidance and use a minimum descent altitude instead, so there isn’t a decision altitude to reach. The other terms aren’t standard decision points for these approaches.
