welded and bolted to the flight deck inboard of each of
the deck sheaves at an approximate 45 degrees forward
facing angle. The bolted section of the frame is
removable in order to replace worn impact pads as
needed. Upon initial arrestment by an aircraft the
terminal will impact on the pads instead of the steel
deck, minimizing damage to the fittings, purchase
cable, and crossdeck pendants.
Wire Supports
The wire supports provide a method of raising the
crossdeck pendant off the flight deck to ensure arresting
(tail) hook engagement of the incoming aircraft.
These wire supports are actually preshaped leaf
springs that are designed to maintain a crossdeck
pendant height of 2 inches minimum, measured from
the bottom of the pendant to deck at its lowest point,
and 5 1/2 inches maximum, measured from the top of
the pendant to the deck at its highest point (fig. 3-34).
The crossdeck pendant height is regulated by adjusting
the wire support's contour height.
Each wire support is mounted directly to the flight
deck. The forward end of the wire support spring is
rigidly secured by use of a cam mounted in a deck
recess and a follower and pin at the end of the wire
support. The forward end of the spring is then held in
