NOTES:

1. q vernier will be set at 33°, a crosspointer will null at 20°, RAS cutoff will be set at 2.5 g.

2. Emergency lake: Hidden Hills and Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 57,000# (100%) and 36,800# (50%) thrust engine. Total burn time at 100% = 83 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.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper

Total Roll Damper

(Turn Yaw off)

 (a) 0 - 40 sec.

Pushover to .2 g at 40 sec. and reduce to 50% T at 50 sec., shutdown at 5000 fps and extend S.B. to 20°. Retract S.B. at 4500 fps. Hmax » 135,000 ft).

Maintain a > 0°.
       
    (b) 40 sec. to S.D.

Pushover to .2 g and reduce to 50% T when failure occurs, shutdown at 5000 fps and extend S.B. to 20°. Retract S.B. if reentry is required. Maintain a > 0°.
       
    (c) After S.D.

Use » 15° a for reentry (» 1000 q reentry).
       
3. Total Yaw Damper   Proceed as Planned. Maintain a > 0°.
       
4. Attitudes (a) 0 - 40 sec.

Use 5° a at 24 sec. instead of 33° q, then proceed with 2(a).
       
    (b) 40 sec - S.D.

Same as 2(b).
       
5. Ball Nose (a) 0 - 40 sec.

Same as 2(a).
       
    (b) 40 sec. - S.D.

Same as 2(b). Use q = 0° for reentry.
       
6. Delayed engine light   Proceed - shutdown at 5200 fps.
       
7. Inadvertent engine shutdown:

00 - 46 sec. Delamar

46 - 65 sec. Hidden Hills (2700 fps)

65 - 70 sec. Cuddeback (3900 fps)

70 - Up Edwards (4300 fps)
