19. High Key - check flap and "squat" circuit breakers in.

20. Before APU shutdown, cycle flaps, set stabilizer trim to zero, data off.

Notes:

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

2. Emergency Lakes: Grapevine and Cuddeback.

3. Flight duration: Approximately 10 min.

4. Flight plan based on 60,000# thrust - engine #106

Total burn time at 100% = 84 sec.

Launch weight = 34,600#, burnout weight = 16,450#

Ground jettison check

Ground Rules for No Launch: 1. Radio, Radar, or TM Malfunction.

2. Malfunction of any SAS channel.

3. Malfunction of inertial platform.

4. Total ball nose failure.

5. APU gearbox pressurization malfunction.

Alternate Situations After Launch:

Failure Action

1. Radio or Radar Proceed as planned.

2. Total Pitch Damper Proceed as planned. Manipulate roll and yaw dampers at pilot's discretion.

3. Total Yaw Damper Proceed as planned.

4. Total Roll Damper Proceed as planned, turn yaw damper "off." Manipulate pitch damper at pilot's discretion.

5. Attitude Failure Use 5° a instead of 30° q at 27 sec. Disengage dampers at pilot's discretion.

6. Ball Nose Rotate at 2g instead of 10° a. Do not disengage dampers.

7. Delayed engine light Pushover to "0" g at 52,000 ft. (H-dot = 900 fps).

8. Inadvertent engine shutdown
