10. 297 70 3000 9 660 Abeam Cuddeback. Maintain Hdot » -300 fps during vector to High Key. Speed brakes as required. Engine Master OFF.
             
11.           High Key. Check flap and "squat" circuit breakers in. Arm stick kicker and third skid. Window shade down.

NOTES:

1. q vernier will be set at 34°, a crosspointer will null at 20°.

2. Emergency Lake: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 60,000# thrust at 100%. Engine #104.

Total burn time at 100% T (60,000#) = 85.7 sec.

 Launch wt. = 34,832# S.D. Wt. = 16,768# Burnout wt = 15,726#

5. In-flight jettison check. (Accounted for in wts. and burn time.)

6. Precision attitudes pre-set:

Pitch = 0° (90.0)

Roll = 0° (90.0)

Heading = 201°

 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.

5. Malfunction of either BCS.
 
 

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

Total Roll Damper

(Turn Yaw OFF)

Total Yaw Damper

Failure to ASAS

 2a. 0 - 35 seconds

Pushover to a = 2° at 35 sec. Shutdown at 5150 fps (79 sec) (Hmax » 140K).
       
    2b. 35 sec - shutdown

Pushover to a = 2° when failure occurs. Reduce to min. thrust if necessary to reduce max. altitude. Shutdown at 5150 fps.
       
    2c. After shutdown

Use a = 15° for entry.
       
3. Ball Nose Failure  3a. 0 - 35 seconds

Rotate at 2.0g. Pushover to zero g at 35 sec. Shutdown at 5150 fps. (79 sec). (Hmax » 115K).
       
    3b. 35 sec. - shutdown

Pushover to zero g when failure occurs. Shutdown at 5150 fps.
       
    3c. After shutdown

Use q = 0° for reentry.
       
4. Attitude Failure 4a. 0 - 35 seconds

Use 9° a at 25 secs. instead of 34° q, then proceed with 3a.
       
    4b. 35 secs. to shutdown

Same as 3b.
       
    4c. After shutdown

Proceed as planned.
       
5. Inertial Failure 5. Proceed as planned.
       
6. Delayed Light 6. Proceed as planned.
       
  INADVERTENT ENGINE SHUTDOWN:
