NOTES:

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

2. Emergency Lakes: Hidden Hills and Cuddeback.

3. Flight Duration: Approximately 11 minutes.

4. Flight plan based on 57,250# thrust engine.

Total burn time at 100% = 88.7 sec.

Launch wt. = 33,150#, Burnout wt. = 14,950#.

 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, except pushover to 2° a at 53,000 ft. instead of zero g.
       
3. Total Yaw Damper   Same as 2.
       
4. Total Roll Damper   Same as 2 except turn Yaw Damper off.
       
5. Attitude Failure   Use 5° a in place of 30° q.
       
6. Ball Nose   Proceed as planned.
       
7. Delayed engine light   Pushover to zero g at H = 58,000 ft. (Hdot » 1000 fps).
       
6. Inadvertent engine shutdown:

00 - 45 sec. Delamar

45 - 68 sec. Hidden Hills (2700 fps)

68 - 73 sec. Cuddeback (4200 fps)

73 - Up Edwards (4600 fps)
