NOTES:

1. q vernier will be set at 20°, a crosspointer will null at 5°.

2. Emergency lake: Three Sisters and Cuddeback.

3. Flight Duration: Approximately 9 minutes.

4. Flight plan based on 56,000# thrust engine (35,200# for 50%).

Total burn time at 50% = 133 sec.

Launch wt. = 32,800#, Burnout wt. = 15,000#.

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

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Malfunction of Ball Nose.

5. APU gearbox pressurization malfunction.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper   Proceed as planned.
       
3. Total Yaw Damper   Proceed as planned except pushover to 2° a at 69 sec. instead of 0 g. Do not perform roll and rudder pulse maneuvers.
       
4. Total Roll Damper   Same as 3 except turn Yaw Damper "OFF.".
       
5. Attitude Failure   Use 5° a in place of 20° q at 26 sec. 
       
6. Ball Nose   Proceed as planned. Use 1.5g at 10 sec. instead of 10° a for rotation.
       
7. Delayed engine light   Pushover to zero g at H = 65,000 ft (Hdot = 600 fps).
       
8. Inadvertent engine shutdown:

00 - 72 sec. Hidden Hills

72 - 78 sec. Three Sisters (2400 fps)

78 - 95 sec. Cuddeback (2600 fps)

95 - Up Edwards (3200 fps)
