NOTES:

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

2. Emergency lake: Hidden Hills and Cuddeback.

3. Flight Duration: Approximately 11 minutes.

4. Flight plan based on 58,500# thrust engine. Total burn time at 100% = 81 sec. Launch wt. = 32,800#, burnout wt. = 15,000#.

GROUND RULES FOR NO LAUNCH: 1. Malfunction of any SAS channel.

2. Malfunction of inertial platform attitudes.

3. Malfunction of ball nose.

4. APU gearbox pressurization malfunction.

5. Camera malfunction.

6. In case of no launch, B-52 will return to Edwards via the X-15 track if practicable.

ALTERNATE SITUATIONS AFTER LAUNCH:

1. Radio or Radar		Proceed as planned

2. Total Pitch Damper		Maintain a > 0°, proceed as planned.

3. Total yaw damper		Maintain a > 0°, shutdown at 5000 ft/sec. Maintain 20° speed brakes until V = 4500 ft/sec.

4. Total roll damper		Same as 3 except turn yaw damper off.

5. Attitude failure		Use 5° a in place of 30° q. After burnout fly 6° a until » 4000 ft/sec (Ground call), then fly 4° a to Cuddeback.

6. Ball nose		Proceed as planned. Use "0" g instead of 0° a.

7. No engine light within 30 seconds		Jettison propellants and land at Delamar.

8. Delayed Engine light		Pushover to zero g at 55,000 ft.

9. Inadvertent engine shutdown:

0 - 37 sec. (2300 ft/sec)	Delamar
45 - 66 sec. (2700 ft/sec)	Hidden Hills
66 - 71 sec. (4200 ft/sec)	Cuddeback
71 - Up (4600 ft/sec)	Edwards
