the deck recess by the cam-end disc and the cam-end
forward stop (fig. 3-35).
Adjustment of the wire support spring height is
made at its aft end. The aft end of the wire support is
also pinned, and set between adjustable forward stops
as required (fig. 3-35).
Wire supports are replaced when they become
deformed or damaged or when they fail to maintain the
required crossdeck pendant height of 2 inches
minimum and 5 1/2 inches maximum as measured
using a cable height gauge (fig. 3-34).

EMERGENCY RECOVERY
EQUIPMENT
LEARNING OBJECTIVES: Describe the
components
of
the
emergency
recovery
equipment. Describe the operation of the
emergency recovery equipment.
The emergency recovery equipment (barricade
installation) is used when an aircraft cannot make a
normal (pendant) arrestment. Emergency recovery
equipment consists of the following:
Barricade power package
Pendant and anchor installation
Barricade stanchions and controls
Barricade webbing assembly
Deck ramp installation
The
arresting
engines
used
for
barricade
arrestments are identical to those used for deck pendant
