Notes:

1. Duration of flight approximately 11 minutes.

2. Emergency lakes - Grapevine and Cuddeback

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

 Ground Rules For No Launch: l. Malfunction of any SAS channels

2. Malfunction of inertial platform attitudes

3. Malfunction of hot nose

4. Malfunction of microwave

 Alternate Situation After Launch: 1. If engine light cannot be accomplished within 30 sec, jettison propellants and land at Mud Lake.

2. For delayed engine light add 5 seconds to pushover time.

3. If radio or radar fail proceed as planned .

3. For inadvertent engine shutdown:

Prior to 35 sec, return to Mud Lake

35 - 65 sec, proceed to Grapevine

60 - 65 sec, proceed to Cuddeback

65 seconds or more proceed to Rogers

Two engine starts may be attempted at any time.

5. For total pitch or roll damper failure proceed to Rogers. Do not increase a above 12°.

6. For ball nose failure, maintain 2g until q =30°, pushover at 35 seconds proceed to Rogers. Make ASAS checks during deceleration..

7. For attitude failure, maintain 1.5g until 40 seconds, pushover to 0 g proceed to Rogers, make ASAS checks during acceleration.
