BARRICADE WEBBING ASSEMBLY
Since barricade arrestments are emergency
situations, barricade rigging operations must be swift
and efficient.
The barricade webbing assemblies
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 hydraulic 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 arrestment with four exceptions: (1) no
fluid coolers are installed, (2) barricade engines are
endless reeved, (3) no anchor dampers are installed,
and (4) a short-stroke control value cam is used on
most carriers.
(fig. 3-32) are preassembled and stored in an area
where the webbing assemblies will be readily
accessible when an emergency situation arises. The
storage area for the webbing assemblies must be dry
and must protect the webbing from exposure to
direct sunlight. The effects of water on a barricade
webbing assembly will result in the loss of
approximately 10 to 15 percent of the webbing’s
strength.
Newly constructed barricade webbing assemblies
may be brought out of storage and used as follows:
If used for three practice rigs, it can still be
used as a “ready” barricade for engagements.
If used for four or more practice rigs, it
cannot be used as a “ready” barricade.
When an aircraft is required to make an
emergency landing, the nose of the aircraft passes
through the barricade and allows the vertical
(engaging) straps to contact the leading edges of the
