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). REVIEW QUESTIONS Q1. What is considered the heart of the arresting engine? Q2. What permits the return of hydraulic fluid from the accumulator to the main engine cylinder? Q3. What is the capacity of the fluid stowage tank? Q4. What is the pitch diameter of the sheaves on the  outboard  shaft  of  the  crosshead assembly? Q5. What system transfers energy from an arresting aircraft to the arresting engine? Q6. What reduces peak cable tension? 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 3-34 AFT COVER ABEf0335 PIVOT END BASE LOCK PLATE FORWARD ADJUSTING SCREW SPRING CAM CAM-END FORWARD STOP CAM-END DISC SPRING FORWARD STOP FORWARD ADJUSTING SCREW (TURN SCREW IN) AFT STOP AFT ADJUSTING SCREW (TURN SCREW OUT) FORWARD FORWARD STOP SPRING FORWARD ADJUSTING SCREW (TURN SCREW OUT) AFT STOP AFT ADJUSTING SCREW (TURN SCREW IN) TO LOWER SPRING TO RAISE SPRING Figure 3-35.—Adjusting the wire support leaf spring height.
