INTEGRATED CATAPULT CONTROL STATION (ICCS) SUSPEND PROCEDURES A catapult launch can be halted at any time up until the fire pushbutton has been depressed by actuating a catapult suspend switch. Suspend switches are located at pri-fly, launching officer’s console, monitor console, central charging panel, and at the water brake station. NOTE If the suspend switch at the water brake station is actuated during catapult operations, breaking  tension  by  energizing  maneuver  aft cannot occur. If this switch initiated a suspend action,    the    charging    panel    operator    shall actuate   suspend   and   direct   the   water   brake station to release the water brake suspend. Actuation  of  any  catapult  suspend  switch  lights  a red flashing light mounted at the edge of the flight deck near the battery position for the associated catapult. The operator   initiating   the   suspend   must   immediately inform   the   launching   officer   of   the   reason   for   the suspend.   The  launching   officer  shall  determine   the action to be taken for resolution. If the suspend action occurs prior to aircraft hookup, the aircraft shall be held short of the hookup position until the problem has been rectified or the catapult is placed in the down status. If a suspend occurs after an aircraft has been tensioned, the following apply: 1. The safety observer signals suspend to the pilot and  other  members  of  the  aircraft  launching team. 2. The launching officer shall immediately depress the suspend pushbutton. 3. The safety observer shall ensure that the deck suspend  light  is  on  and  signal  the  launching officer to maneuver aft. 4. The launching officer depresses and holds the maneuver  aft  pushbutton  until  the  grab  and shuttle are moved fully aft. 5. After  the  shuttle  has  moved  aft,  the  safety observer signals the pilot to raise launch bar. 6. For aircraft with NGL selector switch (F/A 18 and S-3): 1)    With   the   launch   bar   raised,   the   safety observer gives the bridle tension signal to the launching officer. 2)    The launching officer depresses the bridle tension  pushbutton  to  position  the  shuttle forward of the launch bar. When the shuttle has  moved  forward  of  the  launch  bar,  the launching  officer  shall  momentarily  press the maneuver aft pushbutton. 3)    The  safety  observer  shall  step  in  front  of the aircraft and in view of the pilot, give the throttle back signal. 7. For  aircraft  with  manual  launch  bar  (E-2  and C-2): 1)    After the shuttle has moved aft, the safety observer shall ensure that the catapult is in the suspend condition, step in front of the aircraft  and  in  full  view  of  the  pilot,  give the throttle back signal. 2)    With  the  aircraft  at  idle  power  the  safety observer  directs  the  topside  safety  petty officer to approach the aircraft and manually hold the launch bar high enough to permit shuttle clearance. 3)    With  the  launch  bar  held  clear,  the  safety observer gives the bridle tension signal to the launching officer. 4)    The launching officer depresses the bridle tension  pushbutton  to  position  the  shuttle forward of the launch bar. When the shuttle has  moved  forward  of  the  launch  bar,  the launching officer shall momentarily depress the maneuver aft pushbutton. 8. At this time, if the condition that initiated the suspend   action   has   been   corrected   and   the aircraft  and  catapult  are  both  up,  the  shuttle may  be  maneuvered  aft,  launch  bar  lowered and the aircraft hooked up to the catapult. NON-INTEGRATED CATAPULT CONTROL STATION (ICCS) SUSPEND PROCEDURES A catapult launch can be halted at any time up until the  fire  pushbutton  has  been  depressed  by  actuating  a catapult suspend switch. Suspend switches are located at  pri-fly,  deckedge,  main  control  console,  and  the water brake station. NOTE If the suspend switch at the water brake station is actuated during catapult operations, breaking  tension  by  energizing  maneuver  aft cannot occur. If this switch initiated a suspend action, the main control console operator shall 4-61
