Instrumentation Engineer: Febo Bartoli

Launch: Hidden Hills on a magnetic heading of 235°, MH-96 Adaptive, R.C. "OFF," BCS "OFF," heading vernier to "Standby," ventral off.

Launch point coordinates: 35° 55' N, 115° 39' W.

13. High Key - check flap and "Squat" circuit breakers in. Exp. Switch "OFF."

14. Before APU shutdown, cycle flaps, set stabilizer trim to zero, data "Off."

Notes:

1. q vernier will be set at 20°, a cross-pointer null at 10°.

2. Emergency lakes: Cuddeback.

3. Flight duration: Approximately 8 minutes.

4. Flight plan based on 58,800lb thrust - Engine #106.

Minimum thrust = 29,000lb

Total burn time at 100% = 86 sec.

Launch Wt. = 33,750lb Burnout Wt. = 15,550lb

Ground Rules For No Launch:
1. Radio, Radar, or TM malfunction.

2. FCS malfunctions as indicated on Analyzer check list.

3. Malfunction of Ball Nose.

4. Malfunction of inertial platform.

Alternate Situations After Launch:

	Failure	Action

1.	Radio or Radar	Proceed as planned.

2.	Total Pitch/Roll Damper	Turn Yaw OFF, maintain a > 0. Shutdown at 4500 fps, vector to High Key.

3.	Total Yaw Damper Fixed Gain in any axis	Proceed as planned.

4.	Attitude	Proceed as planned except use 4.5° a in place of 20° q at 20 seconds. Perform roll maneuver at pilot's discretion.

5.	Ball Nose	Heading vernier to ^·y, proceed, use 1.6 g for rotation. Perform roll maneuver at pilot's discretion.

6.	Delayed engine light	Pushover to 0 "g" at H = 60,000 ft.

7. Inadvertent engine shutdown:

0 - 47 sec Hidden Hills

47 - 53 sec Cuddeback (2900 fps)

53 - Up sec Edwards (3300 fps)
