Which option is NOT listed as a critical phase of flight?

• A. Preflight checks on the ground
• B. Hover operations
• C. Takeoff, Approach, and Landing
• D. Immediately prior to level off during climb/descent under IFR

Answer: (A)

Critical phases of flight are the portions of a helicopter’s operation where risk is highest and pilot attention must be fully on the aircraft. Hover operations are particularly demanding because you’re close to the ground with variable lift and precise control needed to stay in a small, stable area. Takeoff and landing are also high-risk transitions where attitude, power, and translational lift must be managed carefully as you move through low airspeeds and altitude. Even during climb or descent under IFR, the crew must maintain strict focus on flight parameters and instrument interpretation in less forgiving conditions. Preflight checks on the ground are part of preparation before flight starts; they occur prior to any flight phase and aren’t a phase of flight itself. While essential for safety, they aren’t categorized as a critical phase of flight.
