8.           Cuddeback - Vector to High Key, speed brakes as required. ASAS "OFF," Roll and Yaw "OFF," perform moderate left and right roll at a» 8°.
             
9.           High Key - check flap and "Squat" circuit breakers in. Data calibrate. Before APU shutdown, cycle flaps, set stabilizer trim to zero, data "OFF."

NOTES:

1. q vernier will be set at 34°, 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.

Total burn time at 100% = 86 sec.

Launch wt. = 33,000#, Burnout wt. = 14,950#, 300# allowed for in-flight jettison.

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

2. BCS System failure.

3. Ball Nose, Inertial Platform or APU Gear Box malfunction.

4. Failure of any SAS channel.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total damper any axis, failure to ASAS (For roll failure turn yaw off) (a) Alternate Flight Plan.

Proceed normally until t = 40 sec. At 40 sec. pushover to 2° a and extend speed brakes to 35°. Shutdown at 5200 fps and retract speed brakes after shutdown. Vector to high key (q » 400 psf). Peak alt 140,000 ft.
       
  (b) Attitude (b) Use 6° a at 22 sec instead of 34° q then proceed with alternate flight plan.
       
  (c) Ball Nose (c) Same as alternate, except use » 0.1 g instead of 2° a. Heading vernier to "·y."
       
3. Total damper any axis, failure to ASAS (For roll failure turn yaw off) (a) Pushover to 2° a and extend speed brakes when failure occurs. Shutdown at 5200 fps. Re-enter at 20° a and 20° speed brakes.
       
  (b) Attitude (b) Same as 3 (a)
       
  (c) Ball Nose (c) Same as 3 (a) except use » 0.1 g instead of 2° a. Use q = 0 for reentry.
       
4. Total damper axis (a) Proceed as planned, RAS "ON," reenter at 20° a.
       
  (b) Attitude  (b) Proceed as planned.
       
  (c) Ball Nose (c) Use q = -5° for reentry.
       
5. Delayed engine light   Proceed - shut down at 5200 fps.
       
6. Inadvertent engine shutdown:

00 - 46 sec. Delamar

46 - 66 sec. Hidden Hills (2650 fps)

66 - 70 sec. Cuddeback (3900 fps)

70 - Up Edwards (4200 fps)
