WINDOWS -NUMBER TWO OPENABLE WINDOW -FUNCTIONAL DESCRIPTION -LATCH/UNLATCH
Latch Functional Description
Four latch pins are on the airplane structure around the window opening. One is on the top, two are on the aft side, and one is on the bottom. The latch cams on the window use these latch pins to latch the window.
When the window is not completely closed, the spring-loaded latch cam hook will not let the latch cam turn. When the window moves to the closed position, the hook striker on the airplane structure moves the latch cam hook. The latch cam is free to turn.
Downward movement of the lock button on the latching handle releases the handle from the handle unlatched striker. Forward movement of the handle causes the teleflex cable to turn the latch cams to a position outboard of the latch pins. The window cannot move inboard. It is latched. The latch striker holds the latch handle.
