ABE TEST 2 STUDY GUIDE
Crossdeck pendants are suspended - Answer -2 to 5 1/2 inches above flight deck
recovery equipment controls are grouped into three areas - Answer -engine rooms,
deck edge, pri-fly station
recovery equipment three major systems - Answer -engine drive system, arresting
engine, emergency recovery equipment
engine drive system components - Answer -crossdeck pendent, purchase cable,
damper sheaves, anchor dampers, various sheave installations
CDP's - Answer -crossdeck pendants - engage arresting hook of aircraft
Purchase Cables - Answer -wire rope connection between cdp's and arresting engine
reeving - Answer -the threading of new purchase cables
sheave damper installation - Answer -reduces peak cable tension by "damping" cable
vibration created by initial impact
retractable deck sheave - Answer -raised and lowered 4 7/8 inches above the flight
deck by electric motor controlled by deck edge push button
arresting engine - Answer -transforms the pull of the purchase cable into hydraulic
resistance
accumulator - Answer -receiving chamber for the fluid, displaced by the ram
accumulator piston - Answer -contains v ring packing that creates a seal between the
fluid and air side of the accumulator
battery position - Answer -ready position
CROV - Answer -constant runout valve
fixed sheave assembly - Answer -two banks of rotating sheaves, nine sheaves in each
bank, each bank mounted on individual shaft
outer and inner bank sheaves diameter - Answer -outer - 33, inner - 28
crosshead assembly - Answer -slippers mounted on each corner of crosshead held in
place by brass retainers, ram is attached to crosshead by bolts and split retainer
, MEC - Answer -main engine cylinder
MEC, ram, elbow assembly - Answer -mec and ram is actual engine of arresting gear,
located within engine between elbow and crosshead
arresting engine process - Answer -pulling of purchase cable moves crosshead forcing
ram into the MEC, forcing fluid from cylinder through runout valve and into accumulator
arresting engine going back to battery position - Answer -stored accumulator air
pressure forces displaced fluid to return to the MEC thereby forcing ram and crosshead
back to battery position
fluid cooler - Answer -107 copper tubes with salt water running through them
maximum fluid temp. for fluid cooler - Answer -170 degrees
emergency recovery equipment - Answer -group of nylon webbing assemblies
suspended across landing area from two 24 ft. tall stanchions
procedure for arresting equipment after a week of being inactive - Answer -it must be
exercised/used in order to keep freedom of movement and proper lubrication
monitoring of equipment settings is the job of - Answer -all hands
arresting gear sound powered phone circuit - Answer -6JG
responsible to make certain all pre operational inspections have been accomplished -
Answer -arresting gear officer
number of conditions of readiness - Answer -4 (ready, standby, secure, inactive)
purpose of arresting engine - Answer -arrest aircraft
used to support MEC, accumulator, fluid cooler and air flasks - Answer -support
saddles and straps
inside diameter of MEC - Answer -20 inches
gallons of ethylene glycol in MEC - Answer -180
purpose of wiper - Answer -remove dirt and grease from ram
angular groove diameter of MEC - Answer -1/2 inch deep
