1. 0 45 790 2 145 Launch, light engine at 75%T. Increase to 100% T. Rotate at a = 11° (» 2g) to q = 38°. .
             
2. 28 53 1900 11 560 q = 38°. Maintain q = 38°.
             
3. 77 138 5150 7 80 Shutdown. Pushover to a = 0°. Maintain a = 0° to peak. Switch to a/b. Roll aircraft ±10° to peak at less than 5°/sec.
             
4. 90 170 5000 0 21 Micrometeorite experiment to extend. JPL switch to "ON."
             
5. 118 220 4600 0 3 Switch to comp. a. F and b to 0° and engage roll hold.
             
6. 163 250 4350 0 1 Peak altitude. Hold F and q ±2° until a = 20°. Engage q hold.
             
7. 204 220 4600 16 3 Switch to ball nose a.
             
8. 223 190 4800 20 10 a = 20°. Disengage pitch and roll hold. Pitch down 5° for 10 seconds. Turn JPL experiment off. Micrometeorite switch to retract. Hold a = 20° until An = 5.0g. Hold 5g until H dot = -800 fps.
             
9. 275 77 4350 20 960 H dot = -800 fps. Pushover to maintain H dot = -600 fps. Speed brakes to 35°.
             
10. 297 66 3650 3 1120 Cuddeback. Vector to hi-key. Speed brakes as required.
             
11.           High Key - check flap and "squat" circuit breakers in. Arm stick kicker and 3rd skid. Engine Master off. Window shade down. Experiment off. Radiometer off. Camera on.

NOTES:

1. q vernier will be set at 38°, a cross-pointer null at 20°.

2. Emergency lake: Hidden Hills, Cuddeback.

3. Flight duration: Approximately 10 minutes.

4. Flight plan based on 60,300lb thrust at 100%. Engine #110.

Total burn time at 100% T. (60,300lb) = 78.6 seconds.

Launch weight = 33,415lb. Burnout weight = 15,225lb

Inflight jettison check (accounted for in weights and burn time).
 

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

2. FCS malfunction as indicated on analyzer check list.

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   Proceed as planned.
       
2. Total pitch damper

Total roll damper

(Turn yaw off)

Total yaw damper

Failure to fixed gain

 (a) 0 - 35 seconds

Pushover to a = 2° at 35 secs. Shutdown at 5150 fps.
       
    (b) 35 sec - shutdown

Pushover to a = 2°. Reduce to Tmin. Shutdown at 5150 fps.
       
    (c) After shutdown

Reenter at a = 15°.
       
3. Ball nose failure (a) 0 - 35 seconds

Pushover to 0g at 35 seconds. Shutdown at 5150 fps. Switch to comp a.
       
    (b) 35 secs - shutdown

Pushover to 0g. Reduce to Tmin. Switch to comp a. Shutdown at 5150 fps. Use q = 5° for reentry. 
       
    (c) After shutdown

Switch to comp a. Use q = -5 for reentry.
       
4. Attitude failure   Use a = 6° at 28 secs in place of q = 38°. Switch to a/b mode, proceed with 3a, b, or c as applicable.
       
5. Inertial failure   Proceed as planned.
       
6. Delayed light   Rotate at 2g. Proceed as planned.
