For the last few days I have been working on the instrument cluster. There are 48 annunciators on the center panel and six of them are for the landing gear.
- LEFT GEAR - Green - Down and Locked
- NOSE GEAR - Green - Down and Locked
- RIGHT GEAR - Green - Down and Locked
- DOOR - Red - Landing Gear Doors
- IN TRANSIT - Red - Landing Gear in Transit
- TRUCK - Amber - One of the landing gear trucks is not level
The gear handle has a lock down solenoid that does not allow the gear level to be moved out of the down position if the aircraft is on the ground. The solenoid is held by 24VDC. The solenoid would be energized once the aircraft is airborne which would allow safe gear retraction.
