What are the Electric Limit Switches
stop the flow of current to the motor of the hydraulic pump when the gear is fully up or fully down position.
Red Warning Light:
- The gear is in transit
- Gear up and MP is below 14”
- Gear selector switch in “up” position when the airplane is on the ground

throttle quadrant activates a warning horn.
(red lights under the following conditions):
- Gear up and MP reduced below 14” on either engine or both
- Gear selector switch “up” position when the airplane is on the ground
Safety Switch
