Which motor is most likely to have an armature brake?

  1. Main propulsion motor

  2. Landing light retraction motor

  3. Battery charging motor

  4. Cabin air circulation fan

The correct answer is: Landing light retraction motor

The correct answer is B. Landing light retraction motor. Landing light retraction motors are often equipped with armature brakes to prevent the landing lights from extending while the aircraft is in flight. This safety feature ensures that the landing lights do not cause any aerodynamic drag or other issues during flight. The other options (A. Main propulsion motor, C. Battery charging motor, D. Cabin air circulation fan) are less likely to have armature brakes since they do not have the same operational requirements as the landing light retraction motor in terms of safety and performance during flight.
