EMERGENCY RECOVERY EQUIPMENT measured 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 3-35
