Which positions of retractable landing gear typically have a position indicator?

Retractable landing gear systems are equipped with position indicators to inform the pilot of the landing gear's status. The correct answer highlights that both the up and locked position as well as the down and locked position have indicators.

Having indicators for both positions is crucial for safety, as it allows the pilot to confirm that the landing gear is correctly positioned either for takeoff or landing. When the gear is retracted (up and locked), it provides an essential visual confirmation that the gear has safely stowed away, thus reducing drag during flight. Conversely, when the landing gear is extended (down and locked), the indicator confirms to the pilot that the landing gear is in place for a safe landing.

If a system had an indicator only for the up and locked position, it would leave the pilot vulnerable to uncertainty regarding the down and locked condition. Conversely, if there were indicators for neither position, the risk of landing without knowing whether the gear is properly deployed or retracted would significantly increase.

Thus, having an indicator for both positions maximizes safety and operational reliability during critical phases of flight.
