Alternate Gear Extension
Pulling the Alternate Gear Release handle mechanically actuates a dump
valve and releases the uplocks. The landing gear starts to extend by
gravity and is assisted by aerodynamic loads. The inboard doors remain
open after emergency extension. The system cannot be reset in flight but
the handle can be partially stowed.
Indications
Landing gear status is displayed on the ASI.
Figure 1-64. ASI Landing Gear Display
The landing gear status indicators will show one of three landing gear
states based on the position of the landing gear switch and the switches
in the landing gear system. The three gear positions are: “UP”, “DN”, or
Cross Hatch (unknown/in transit). The color is green if the landing gear
is down and locked, white if up or in transit, amber if failed and red if
gear warning is active. A white DOOR icon is displayed when either of
the main landing gear inboard doors are not closed.
