2. 24 48 1550 11 580 q = 30°, maintain q = 30°.
             
3. 40 58 2000 5 500 Pushover to zero g.
             
4. 80 80 4350 0 800 Increase a to maintain Hdot = 0.
             
5. 82 80 4500 4 870 Shutdown, maintain Hdot = 0.
             
6. 92 80 4400 4 840 Yaw damper to "Lo." Increase a to 10°, maintain a = 10° until Hdot = +600 fps. Perform moderate rudder step input.
             
7. 109 85 3800 10 480 Hdot = 600 fps - pushover to » 5° a, roll into a 90° left bank, increase a to » 15° and perform several rudder step inputs.
             
8. 132 92 3350 15 270 Peak altitude - decrease a to » 5°, roll to a 60° right bank, (maintain Hdot » -600 fps), increase a to » 15° and perform several rudder step inputs.
             
9. 175 82 3000 15 350 Vector to Cuddeback, maintain Hdot » -400 fps.
             
10. 210 62 2600 6 700 Cuddeback - maintain q and f within ±8°.
             
11 215 61 2400 6 630 Test Mode to Land, vector to High Key, Speed Brakes as required. Yaw Damper "OFF" at pilot's discretion. Perform several moderate rudder pulses. Yaw Damper "Hi."
             
12.           High key - Check flap and "Squat" circuit breakers in. Engine Master "OFF."
             
13.           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 lake: Cuddeback.

3. Flight Duration: Approximately 9 minutes.

4. Flight plan based on 49,200# thrust at 75%.

Total burn time at 75% = 95 sec.

Launch wt. = 32,800#, Burnout wt. = 15,000#.

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

2. Malfunction of any SAS channel.

3. Malfunction of inertial attitudes or velocities.

4. Malfunction of Ball Nose.

5. APU gearbox pressurization malfunction.

 ALTERNATE SITUATIONS AFTER LAUNCH:
 
 
Failure
  
Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch Damper   Proceed, pushover to 2° a at 40 sec. Vector to High Key after shutdown, do not perform pullup and roll maneuvers.
       
3. Total Yaw Damper   Same as 2.
       
4. Total Roll Damper   Same as 3 except turn Yaw Damper "OFF."
       
5. Attitude Failure   Use 6° a in place of 30° q at 24 sec. 
       
6. Ball Nose   Proceed as planned. Rotate at 1.5g instead of 11° a. Heading vernier to "·y." Do not perform pullup and roll maneuvers.
       
7. Delayed engine light   Pushover to zero g at H = 56,000'.
       
8. Inadvertent engine shutdown:

00 - 53 sec. Hidden Hills

53 - 62 sec. Cuddeback (2700 fps)

62 - Up Edwards (3200 fps)
