NOTES:

1. q vernier will be set at 30°, a crosspointer will null at 0°.

2. Emergency Lakes: Grapevine and Cuddeback.

3. Flight Duration: Approximately 8 minutes.

4. Flight plan based on 57,600# thrust engine - Engine #107.

Total burn time at 100% = 83 sec.

Launch wt. = 31,500#, Burnout wt. = 15,250#.

(300# allowed for in-flight jettison check)

 GROUND RULES FOR NO LAUNCH: 1. Radio, Radar or TM malfunction.

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Total Ball Nose failure.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper   Proceed as planned. Manipulate Roll and Yaw dampers at pilot's discretion.
       
3. Total Yaw Damper   Proceed as planned, maintain a > 0°.
       
4. Total Roll Damper   Same as 3 except turn Yaw damper "OFF."
       
5. Attitude Failure   Use 4.5° a in place of 30° q at 23 sec.
       
6. Ball Nose   Proceed, rotate at 2 g to 30° q, do not disengage dampers or pullup after shutdown. Side slip switch to "C. Beta."
       
7. Delayed engine light   Pushover to zero g at 60,000 ft.
