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 58,500# thrust engine.

Total burn time at 100% = 86 sec.

Launch wt. = 33,500#, Burnout wt. = 15,300#.

5. Manual V/H settings:

A = .055

B = .051

C = .047

D = .043

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

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform attitudes.

4. Total Ball Nose failure.

5. APU gearbox pressurization malfunction.

6. "Test" malfunction.

ALTERNATE SITUATIONS AFTER LAUNCH:

	Failure	Action

1.	Radio or Radar	Proceed as planned.

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

3.	Total Yaw Damper	Proceed as planned except pushover to 2° a at 52,000 ft instead of zero g. Heading vernier to "Standby."

4.	Total Roll Damper	Same as 3 except turn Yaw Damper off.

5.	Attitude	Use 5° a in place of 30° q.

6.	Ball Nose	Proceed as planned.

7.	Delayed engine light	Pushover to zero g at H = 55,000 ft (Hdot » 1000 fps.)
