NOTES:

1. q vernier will be set at 30°, a crosspointer will null at 15°.

2. Emergency Lakes: Grapevine and Cuddeback.

3. Flight Duration: Approximately 10 minutes.

4. Flight plan based on 60,700# thrust engine.

Total burn time at 100% = 78.5 sec.

Launch wt. = 32,800#, Burnout wt. = 15,000#.

 GROUND RULES FOR NO LAUNCH: 1. Radio, Radar or TM malfunction.

2. Malfunction of any SAS channel.
