 No. Time Alt Vel a q  Event
             
1. 0 45 790 0 145 Launch, light engine at 75% T. Increase to 100% T. Rotate at a = 11° until q = 30°.
             
2. 22 49 1650 11 520 q = 30°. Maintain q = 30°.
             
3. 38 60 2300 4 605 Pushover to 0g. (Hdot » 1000 fps).
             
4. 82.5 99 5500 0 510 Shutdown. Maintain 0g until Hdot = 400 fps. Then pull up to and maintain a = 15°. Engine master OFF.
             
5. 106 112 5100 15 230 Switch Yaw to low gain. Perform dv pulses.
             
6. 120 120 4900 15 160 Turn both ASAS OFF. Turn Yaw Damper "OFF." Perform dv pulses.
             
7. 135 127 4700 15 100 Turn Roll Damper "OFF." Evaluate controllability.
             
8. 157 130 4550 15 75 Peak altitude.
             
9. 201 115 4350 15 160 At q » 150, turn Roll to low and Yaw to high. Open S.B. to 35°. Pushover to a = 10°, turn Pitch Damper OFF and perform dh pulse.
             
10. 236 90 3900 10 400 Engage Pitch Damper to High. Maintain a = 10° until Hdot = -600 fps. Arm both ASAS.
             
11. 256 77 3350 10 570 Hdot = -600 fps. Maintain Hdot = -600 fps.
             
12. 260 74 3200 5 610 Abeam Cuddeback. Vector to hi-key. Speed brakes as required.
             
13.           High Key. Turn Yaw Damper OFF to evaluate Yaw ASAS. Check flap and "Squat" circuit breakers in. Arm stick kicker and 3rd skid. Engine master OFF. Window shade DOWN.

NOTES:

1. q vernier will be set at 30°, a crosspointer will null at 15°.

2. Emergency Lake: Grapevine, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 59,500# thrust at 100%. Engine #108.

Total burn time at 100% T (59,500#) = 86.7 sec.

 Launch wt. = 34,250# B.O. Wt. = 15,130# Landing wt = 14,845#

c.g = 20.1 c.g. = 16.5 c.g. = 17.6

In-flight jettison check (accounted for in weights and burn time).

5. Select: Precision attitudes

Pitch = 0° (90.0)

Roll = 0° (90.0)

Heading = 168°

 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 both BCS.

6. Partial loss of ablative material on horizontal tail.
 
 

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar 1. Proceed as planned.
       
2. Total pitch damper 2. Pushover to a = 2° at h = 53K (Hdot = 800 fps). Maintain a = 2° until shutdown. Proceed as planned. (Pull-up after shutdown at Hdot = 600 fps).
       
3. Total roll damper 3. Turn Yaw Damper OFF. Same as No. 2.
       
4. Total Yaw Damper 4. Same as No. 2.
       
5. Failure to ASAS 5. Proceed as planned.
       
6. Attitude failure 6. Use a = 5° a in place of q = 30° at 22 seconds. Proceed as planned at Pilot's discretion.
       
7. Ball nose failure 7. Rotate slowly to 2g. Do not perform pull-up or Damper OFF maneuvers. Fly Hdot = -300 to C.B. and Hdot = -400 with full S.B. to Edwards.
       
8. Inertial failure 8. Proceed as planned at pilot's discretion.
       
9. Delayed light 9. Rotate at 2g. Pushover to 0g at h = 56K. Proceed as planned.
       
  INADVERTENT ENGINE SHUTDOWN:

00 - 43 sec. Mud 

43 - 64 sec. Grapevine (2500 fps)

64 - 69 sec. Cuddeback (3900 fps)

69 - Up Edwards (4300 fps)
