17. Before APU shutdown, cycle controls, retract flaps, set stabilizer trim to zero. Data off.

 Notes: 1. Duration of flight approximately 10 min.

2. q vernier will be set at 30°, a crosspointer will null at 0°.

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 retract speed brakes at 20° a.

5. For total roll damper failure, turn yaw damper off, proceed, do not exceed 18° a.

6. For yaw damper failure during power portion, fly a = 2°, after power portion proceed as planned.

7. For ball nose failure, fly 1g proceed to Edwards for landing.

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