No person shall engage in any conversation or other activity that could distract or interfere with a flight crewmember properly conducting their assigned duties during critical phases of flight. Critical phases of flight include but are not limited to: 1. ALL GROUND OPERATIONS INVOLVING AIRCRAFT MOVEMENT 2. TAKEOFF, APPROACH, AND LANDING 3. IMMEDIATELY PRIOR TO LEVEL OFF DURING CLIMB/DESCENT UNDER IFR 4. HOVER OPERATIONS 5. BELOW 300 FEET AGL/AGL DURING APPROACH OR DEPARTURE FROM A HOVER 6. AS DIRECTED BY THE PIC

• A. Hover operations
• B. Cruise flight at altitude
• C. Engine start on the ground
• D. Electrical power-up sequence

Answer: (A)

Focusing on when a flight crew is most vulnerable to distraction helps us understand why hover operations are singled out. Hovering requires precise, ongoing control and constant awareness of nearby obstacles, rotor wash, and airframe attitude, all while managing a tight flight path close to the ground. Any conversation or activity that takes attention away can quickly degrade safe control during this phase, so it’s explicitly listed as a critical phase.

The option describing hover operations matches that listed category, making it the best choice. Other options describe times that aren’t specified as critical phases in the given rule—cruise flight at altitude is a stable, lower-workload period, and engine start on the ground or electrical power-up sequence aren’t identified as critical phases in this context (though they may involve procedures). The rule does allow the PIC to designate other times as critical, but hover operations are clearly included.
