NOTES:

1. q vernier will be set at 39°, a cross-pointer null at 22°.

2. Emergency lake: Mud, Grapevine, Cuddeback.

3. Flight duration: Approximately 11 minutes.

4. Flight plan based on 60,600lb thrust at 100%. Engine #110.

Total burn time at 100% T. (60,600lb) = 81.1 seconds.

Launch weight = 34,235lb. Burnout weight = 15,741lb

Ground jettison check.

5. Precision attitude set: Pitch = 0.0

Roll = 0.0

Heading = 168°
 

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.

6. Malfunction of precision heading.
 

ALTERNATE SITUATIONS AFTER LAUNCH:
  Failure   Action
       
1. Radio or radar   Proceed as planned.
       
2. Any damper failure or failure to fixed gain (a) 0 - 35 seconds

Use q = 30° in place of q = 39°. Pushover to a = 2° at 35 seconds. Proceed to burnout (5600 fps, Hmax = 140K).

       
    (b) 35 sec - burnout

Pushover to a = 2° when failure occurs. Proceed to burnout. If reentry is required, use a = 15° up to 250K. Then use a = 17°.

       
    (c) After burnout

Reenter using a = 17° and speed brakes = 20°.

       
3. Ball nose failure (a) 0 - 35 seconds

Switch to comp a. Pushover to 0 g at 35 seconds. Proceed to burnout. (5575 fps, Hmax = 138K). 

       
    (b) 35 secs - burnout

Switch to comp a. Pushover to 0 g when failure occurs. Proceed to burnout. If reentry is required, use q = 0 to 200K and q = -5 to 250K. (dHmax = -25°)

       
    (c) After burnout

Switch to comp a. Use q = -10 for reentry. (dHmax = -25°)

       
4. Attitude failure   Use a = 6° at 30 secs in place of q = 39°. Switch to a/b mode, proceed with 3a, b, or c as applicable.
       
5. Inertial failure   Proceed as planned.
       
6. Delayed light   Proceed as planned. Rotate at 2g.
