NOTES:

1. q vernier will be set at 38°, a crosspointer will null at 21°.

2. Emergency Lakes: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 57,250# thrust engine - Engine #108.

Total burn time at 100% = 86 sec.

Launch wt. = 33,150#, Burnout wt. = 15,250#, 300# allowed for in-flight jettison.

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

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Malfunction of Ball Nose.

ALTERNATE SITUATIONS AFTER LAUNCH:

(Turn Yaw Damper OFF)

Total Yaw Damper

Failure to ASAS

(a) 0 - 35 sec.

Pushover to 2° a at 35 sec., shutdown at 5150 fps. (Hmax » 150).

       
    (b) 35 sec. - S.D.

Pushover to 2° a when failure occurs. Shutdown at 5150 fps. RAS "ON." Reenter at -25° dh and 20° speed brakes.

       
    (c) After S.D.

Proceed as planned, reenter at 21° a.

       
3. Attitude Failure (a) 0 - 35 sec.

Use 6° a at 29 sec. instead of 38° q, then proceed with 2(a).

       
    (b) 35 sec. - S.D.

Same as 2(b).

       
    (c) After S.D.

Proceed as planned.

       
4. Ball Nose (a) 0 - 35 sec.

Same as 2(a) except use » 0.1g instead of 2° a.

       
    (b) 35 sec. - S.D.

Same as 2(b), except use » 0.1g instead of 2° a. Use q = -5 for reentry.

       
    (c) After S.D.

Use q = -5 for reentry.

       
      Pushover to zero g at H = 65,000 ft. (Hdot » 600 fps).
