15.           Before APU shutdown, cycle controls, retract flaps, trim stabilizer zero, data off.

Notes:

1. q vernier will be set at 25°, a cross-pointer null at 20°.

2. Duration of flight approximately 10 minutes.

3. Emergency lakes: Grapevine and Cuddeback.
 

 Alternate Situations After Launch:  
1. For radio or radar failure, proceed as planned.

2. If engine light cannot be accomplished within 30 sec., jettison propellants and land at Mud Lake.

3. For delayed engine light, proceed as planned.

4. For total pitch damper failure, proceed, do not exceed 15° a.

5. For FCS failure to fixed gain in yaw, proceed as planned.

For FCS failure to fixed gain in roll, set yaw fixed, proceed.

For FCS failure to fixed gain in pitch, proceed but do not exceed 20° a.

6. For total roll damper failure, turn yaw damper off, proceed, do not exceed 20° a.

7. For total yaw damper failure, proceed as planned.

8. For attitude failure, proceed, do not exceed 15° a.

9. For inadvertent engine shutdown:
 

 0 - 45 sec Mud.

45 - 65 sec Grapevine.

65 - 70 sec Cuddeback.

70 - Up sec Edwards.
