LANDING GEAR RETRACTED
When the NLG RA and MLG RA are fully retracted and each landing gear
contacts the relevant UP microswitch on the airframe, the corresponding
NOSE, LH or RH amber light on the LGCP extinguishes.
Both VALVE 1 and VALVE 2 UP solenoids remain energized to keep the
pressure in all actuators as long as the LG is retracted
