10.           High Key. Check flap and squat circuit breakers in. Arm stick kicker and third skid. Engine master OFF. Window shade down.

NOTES:

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

2. Emergency Lake: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 59,500# thrust at 100%. Engine #104.

Total burn time at 100% T (59,500#) = 86.8 sec.

 Launch wt. = 34,833# S.D. Wt. = 16,996# Burnout wt = 15,708#

c.g = 19.7 c.g. = 16.1 c.g. =

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

5. Precision attitudes pre-set:

Pitch = 0° (90.0)

Roll = 0° (90.0)

Heading = 213°

 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. Any Damper Failure

(For Roll Fail, Turn Yaw Off)

 2a. 0 - 35 seconds

Pushover to a = 2° at 35 sec. Shutdown at 5200 fps.
       
    2b. 35 sec - shutdown

Pushover to a = 2° when failure occurs. Shutdown at 5200 fps. Use a = 15° if reentry is required. (RAS "ON).
       
    2c. After shutdown

Proceed as planned. Reenter at a = 15°. (RAS "ON").
       
3. Ball Nose Failure  3a. 0 - 40 seconds

Rotate to 2g. Pushover to 0g at 40 sec. Shutdown at 5200 fps.
       
    3b. 40 sec. - shutdown

Pushover to 0g when failure occurs. Shutdown at 5200 fps. Use q = 0° for reentry, if required.
       
    3c. After shutdown

Proceed as planned. Use q = 0° for reentry.
       
4. Attitude Failure 4. Use a = 5° in place of q = 28° at 22 sec. Proceed with 3a, b, or c.
       
5. Inertial Failure 5. Proceed as planned. Shutdown at 81 seconds.
       
6. Delayed Light 6. Rotate to 2g. Proceed as planned.
       
  INADVERTENT ENGINE SHUTDOWN:
