The  Mk  7  Mod 0/2 JBD consists of a total of how many panel assemblies? 1. Six 2. Two 3. Eight 4. Four 4-2. A  total  of how  many  hydraulic  cylinders  are used   to   raise   and   lower   each   pair   of   JBD panels? 1. Six 2. Two 3. Eight 4. Four 4-3. The removable module assemblies are attached to the JBD panel assembly by what devices? 1. Welds 2. Clamps 3. Edge-fitted brackets 4. Screws 4-4. What devices control the flow of cooling water through the Mk 7 JBD panel module assemblies? 1. Throttle valves 2. Vacuum breaker valves 3. Orifices 4. Manual hand valves 4-5. The  JBD  cooling  water must be maintained at what minimum pressure? 1. 60 psi 2. 70 psi 3. 80 psi 4. 90 psi 4-6. The   emergency   lowering   hydraulic   bypass lines permit fluid to bypass what component of the JBD hydraulic system? 1. The lowering side of the hydraulic cylinder 2. The solenoid manual override 3. The stack valve 4. The gravity tank 4-7. JBD  control  is  transferred  from  the  portable control  box  to  the  auxiliary  control  panel  by what switch? 1. A manual override switch 2. The defeat interlock switch 3. The portable control box suspend switch 4. A rotary type switch 4-8. In the event of an electrical power failure, how may the Mk 7 JBDs be raised or lowered? 1. By the auxiliary control panel 2. By the portable control box group UP-DOWN toggle switch 3. By  the  manual  override  on  the  four-way control valves 4. By a tow tractor and cable 4-9. When  it  is  necessary  to  remove  a component from  the  hydraulic  system,  you  should  cap  or plug  the  open  lines  to  prevent  foreign  matter contamination. 1. True 2. False 4-10. What  is/are  the  advantage(s)  of  the  nose  gear launch  system  over  the  conventional  launch system? 1. It   permits   positive   engagement   of   the aircraft to the catapult 2. It   minimizes   the   number   of   personnel required   to   be   near   the   aircraft   during hookup operations 3. It  permits  automatic  engagement  of  the aircraft to the catapult 4. All of the above 4-11. Inserts in the NGL guide track ensure that the aircraft launch bar makes positive contact with which of the following components? 1. The slide 2. The buffer hook actuator roller 3. The track seal 4. The soft-stop buffer 19
