NOTES:

1. q vernier will be set at 28°, a crosspointer will null at 20°.

2. Emergency Lakes: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 58,500# thrust engine.

(Minimum thrust = 33,700#).

Total burn time at 100% = 85 sec.

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

5. Manual V/H settings:

A = .053 D = .031

B = .049 E = .027

C = .045 F = .023

 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.

5. APU gearbox pressurization malfunction.

6. "Test" malfunction.

 ALTERNATE SITUATIONS AFTER LAUNCH:

1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper

Total Roll Damper

(Turn Yaw Damper OFF)

Total Yaw Damper

Failure to ASAS

 (a) 0 - 40 sec.

Pushover to 2° a at 40 sec., reduce to min. T at 50 sec., extend speed brakes to 20° at 60 sec. and shut down at 5000 fps. Retract speed brakes after shutdown. (Hmax » 110K).
       
    (b) 40 sec. - S.D.

Pushover to 2° a, reduce to min. T, and extend S.B. to 20° when failure occurs; shutdown at 5000 fps RAS "ON." Reenter at 15° a.
       
    (c) After S.D.

Proceed as planned, reenter at 15° a.
       
3. Attitude (a) 0 - 40 sec.

Use 6° a at 20 sec. instead of 28° q, then proceed with 2 (a).
       
    (b) 40 sec - S.D.

Same as 2 (b).
       
    (c) After S.D.

Proceed as planned.
       
4. Ball Nose (a) 0 - 40 sec.

Same as 2 (a), except use » .1 g instead of 2° a.
       
    (b) 40 sec. - S.D.

Same as 2 (b), except use » .1 g instead of 2° a. Use q = 0 for reentry.
       
    (c) After S.D.

Use q = 0 for reentry.
       
5. Delayed engine light   Proceed - shutdown at 5200 fps.
       
6. Inadvertent engine shutdown:

00 - 45 sec. Delamar Lake

45 - 64 sec. Hidden Hills (2600 fps)

64 - 68 sec. Cuddeback (4100 fps)
