LANDING GEAR
AL250 Flight Manual
MEP
The three green annunciators form a triangle. The right-hand light represents the
right main gear, the left-hand light the left main gear, the top light the nose gear.
When none of the annunciators are lit, the landing gear is retracted. When three
greens are lit, the landing gear is extended and locked. When the red warning light is
lit, the gear is on its way up or down. The landing gear extension (or retraction) time
should not exceed 7.5 seconds. If the re d warning light located on the central flight
deck stays lit longer, then:
• If no green light is lit, none of the gears are locked in the correct position.
• If one or two green lights are lit, only the gear(s) corresponding to the lights is
(are) locked in the correct position.
GEAR WARNING SYSTEM
There is a gear warning horn which will sound and the red annunciator located on the
central flight deck will blink when the gear is not down and locked and
• power is set to idle on either engine
• or/and the flaps are lowered
BREAKER
The landing gear system is protected by a breaker located on the breaker panel. If the
breaker is disengaged, moving the gear lever will not move the landing gear.
