Section 7 – Airframe and Systems description
LANDING GEAR SYSTEM
The three green lights illuminate only when the respective gear is “down-locked”;
the red light indicates the gear is in transit “up” or “down” and the amber caution
light GEAR PUMP ON indicates that the pump is electrically supplied.
The red transition light extinguishes only when all the three gear legs are “down-
locked” or they are “up” while the amber caution light extinguishes only when the
electrical pump is “off”.
The Up/Down limit switches control the LG lights lighting and pump operation on
the basis of LG configuration set by the pilot through the LG control knob.
A “push to test” button is used to check that the landing gear position lights are
operating.
A warning horn alerts the pilot when the LG control knob is in UP position and at
least one of the two throttle levers and/or flaps are respectively set to idle and to
LAND position.
During emergency extension, LG position lights work as per normal extension
mode: for this reason the LG control knob must be set on DOWN position before
starting the emergency procedure.
IMPORTANT
After each emergency landing gear extension, apply the restoration procedure
described in the AMM.
