Landing Gear Lever
Provides electrical signals to the two LGCIUs which control the green hydraulic supply.
- UP - Retracts landing gear. When the gear doors open, the main wheels
are automatically braked by the normal brake system. The nose wheel
are stopped by a brake band in the gear well during door closure.
When the lever is UP, the hydraulic supply is automatically cut off
above 260 KIAS
- DOWN - Extends the landing gear. The system remains pressurized if green
hydraulic pressure is available. An interlock mechanism prevents unsafe
retraction by locking the lever in the DOWN position when any gear
shock absorber is compressed or the nosewheel steering is not centered.
