 No. Time  Alt  V   a q            Event
             
1. 0 45 790 2 145 Launch, light engine at 100%T. Rotate at a = 10° until BG vernier is nulled. Maintain BG vernier nulled until shutdown. Items 2-5 will be crosschecked (or flown if BG malfunctions).
             
2. 18 46 1600 10 560 q = 20°. Maintain q = 20° until h = 60K.
             
3. 43 60 2850 3 930 h = 60K. Pushover to a = 1°. Maintain a = 1° until just prior to shutdown. (An » 0.2g).
             
4. 60 74 3900 1 880 V = 3900 fps. Roll to F = 90° left bank. Pushover to 0g.
             
5. 67 78 4500 0 960 V = 4500 fps. Shutdown. Pullup rapidly to a » 15°. (An » 3.8). Pushover to 0g until H dot = 0 fps. Maintain H dot = 0 fps until 50 N.M. Switch to a/b mode. Engine Master OFF.
             
6. 137 85 3650 3 450 50 N.M. Pushover to 0g until H dot = -300 fps. Maintain H dot = -300 fps. Switch to comp. a.
             
7. 180 73 3250 4 650 Cuddeback. Extend speed brakes to 35°. Maintain H dot = -300 fps. Vector to Hi-Key. Switch back to Ball Nose a before reaching Hi-Key.
             
8.           High Key - Check flap and "squat" circuit breakers in. Arm stick kicker and third skid. Engine Master "OFF." Window shade(s) down.

NOTES:

1. q vernier will be set at 20°, a cross-pointer null at 5°.

2. Emergency lake: Cuddeback.

3. Flight duration: Approximately 10 minutes.

4. Flight plan based on 60,000lb thrust at 100%. Engine #103.

Total burn time at 100% T. (60,000lb) = 82.9 seconds.

Launch wt = 33,190lb Shutdown wt = 18,596lb Burnout wt = 15,129lb

c.g = c.g. =

5. In-flight jettison check (Accounted for in wts. and burn time).

6. Precision attitudes preset: Pitch = 20° (110.0)

Roll = 0° (90.0)

Heading = 231°
 

 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.
 

 ALTERNATE SITUATIONS AFTER LAUNCH:
  Failure   Action
       
1. Radio or radar   Proceed as planned.
       
2. Total Pitch Damper   Proceed as planned but do not perform roll or pullup maneuvers.
       
3. Total Roll Damper   Same as 2. (Turn Yaw off).
       
4. Total Yaw Damper   Same as 2.
       
5. Failure to Fixed Gain   Proceed as planned.
       
6. Ball Nose Failure   Switch to comp. a. Proceed as planned. If on profile at shutdown, perform pullup to 3g.
       
7. Attitude Failure   Use a = 5° (An = 0.9g) in place of q = 20°. Proceed as planned.
       
8. Inertial Failure   Proceed as planned.
       
9. Delayed Light   Rotate at 2g. Pushover at h = 58K. Proceed as planned.
       
10. BG malfunction   Switch to a/b. Proceed as planned.

INADVERTENT ENGINE SHUTDOWN:

0 - 41 sec Hidden Hills

41 - 49.5 sec Cuddeback (2700 fps)

49.5 - Up sec Edwards (3200 fps)
