Instrumentation Engineer - (Don Yount)

 Launch: Delamar Lake #1 on magnetic heading 214°, SAS Hi-Lo-Hi (8-4-8), ASAS Armed, both BCS "OFF", RAS "OFF," Ventral OFF.

Launch Point Coordinates: 37° 18' N, 114° 36' W

6. 99 104 4900 0 342 Peakaltitude - increase a to maintain Hdot = -200 fps.
             
7.           Cuddeback - Vector to High Key. Speed brakes as required. Engine Master "OFF."
             
8.           High Key - check flap and "Squat" circuit breakers in.
             
9.           Before APU shutdown, cycle flaps, set stabilizer trim to zero, data "OFF."

NOTES:

1. q vernier will be set at 30°, a crosspointer will null at 0°.

2. Emergency Lakes: Hidden Hills and Cuddeback.

3. Flight Duration: Approximately 11 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. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Total Ball Nose failure.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper   Maintain a > 0°, proceed as planned.
       
3. Total Yaw Damper   Proceed as planned except pushover to 2° a at 53,000 ft. instead of zero g.
       
4. Total Roll Damper   Same as 3 except turn Yaw Damper off.
       
5 Attitude Failure   Use 5° a in place of 30° q.
       
6. Ball Nose   Proceed as planned.
       
7. Delayed engine light   Pushover to zero g at H = 53,000 ft. (Hdot » 1000 fps).
       
6. Inadvertent engine shutdown:

00 - 47 sec. Delamar

47 - 71 sec. Hidden Hills (2700 fps)

71 - 77 sec. Cuddeback (4200 fps)

77 - Up Edwards (4600 fps)
