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

 

Notes:

1. q vernier will be set at 42°, a cross-pointer null at 23°.

2. Emergency lakes: Hidden Hills and Cuddeback.

3. Flight duration: Approximately 12 minutes.

4. Flight plan based on 58,750lb thrust - Engine (#107).

Total burn time at 100% = 83 sec.

Launch Wt. = 33,700lb Burnout Wt. = 15,550lb
 

 Ground Rules For No Launch:
  1. FCS malfunction as indicated on Analyzer check list.

2. Malfunction of inertial platform.

3. Malfunction of ball nose.

4. Radio, radar or T.M. malfunction.
 

 Alternate Situations After Launch:
  Failure   Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total damper any axis,

failure to fixed gain any axis

(For roll failure turn yaw off)

 (a) 0 - 32 sec.

Alternate Flight Plan.

Proceed normally until t = 32 sec. At 32 sec. pushover to » 2° a and extend speed brakes to 35°. Shutdown at 5200 fps and retract speed brakes to 20° after shutdown. Vector to high key (q » 550 psf). Peak altitude » 145,000 ft.
       
(b) Attitude (b) Hold 11° a till t = 32 sec, then proceed with alternate flight plan.
       
(c) Ball Nose (c) Same as alternate, except use » 0.1 g instead of 2° a. Heading vernier to "·Y."
       
3. Total damper any axis,

failure to fixed gain any axis

(For roll failure turn yaw off)

 (a) 32 sec - S.D.

Pushover to 2° a and extend speed brakes when failure occurs. Shutdown at 5200 fps. Reenter at 20° a and 20° speed brakes.
       
(b) Attitude (b) Same as 3 (a).
       
(c) Ball Nose (c) Same as 3 (a) except use » 0.1 g instead of 2° a. Use q = 0 for reentry.
       
4. Total damper any axis,

failure to fixed gain any axis

(For roll failure turn yaw off)

 (a) After Shutdown

Proceed as planned, reenter at 20° a.
       
(b) Attitude (b) Proceed as planned.
       
(c) Ball Nose (c) Use q = -10° for reentry.
       
5. Delayed engine light   Proceed - shut down at 5000 fps.

 

6. Inadvertent engine shutdown:

0 - 42 sec Delamar

42 - 44 sec

44 - 68 sec Hidden Hills (2555 fps)

68 - 72 sec Cuddeback (3900 fps)

72 - Up sec Edwards (4200 fps)
