NOTES:

1. q vernier will be set at 28°, a crosspointer will null at 20°.

2. Emergency Lakes: Hidden Hills, Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 58,500# thrust engine - engine #107.

Total burn time at 100% = 86 sec.

Launch wt. = 33,500#, Burnout wt. = 15,300#.

5. Manual V/H settings:

A = .053 D = .031

B = .049 E = .027

C = .045 F = .023

 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.

6. "Test" malfunction.

Failure to ASAS

 (a) 0 - 40 sec.

Pushover to 2° a and extend speed brakes to 35° at 40 sec., shut down at 5000 fps. Retract speed brakes after shutdown. (Hmax » 115K).
       
    (b) 40 sec. - S.D.

Pushover to 2° a, and extend S.B. to 35° when failure occurs; shutdown at 5000 fps, RAS "ON." Reenter at 15° a and 20° speed brakes.
       
    (c) After S.D.

Proceed as planned, reenter at 15° a.
       
3. Attitude (a) 0 - 40 sec.

Use 6° a at 22 sec. instead of 28° q, then proceed with 2 (a).
