Someone should be in the cockpit operating what?

• A. The brakes
• B. The rudder
• C. The elevator
• D. The landing gear

Answer: (A)

The brakes are what a person in the cockpit should be operating. On the ground, safe movement and stopping of an aircraft rely on the braking system, which the pilot controls from the cockpit with the toe brakes or brake pedals. This lets you modulate speed, hold position, and stop as needed to prevent collisions on the ramp or runway.

Rudder and elevator are flight controls used for steering and pitch in the air, not for managing ground speed. The landing gear is a configuration system that’s extended or retracted during climb, cruise, and landing, not something used to control taxi speed. So the essential control for safe ground movement is the brakes, operated from the cockpit.
