Flight No. 1-28-49

NOTES:

1. Duration of flight approximately 9 minutes.

2. q vernier will be set at 30°, a crosspointer will null at 0°.

3. Emergency lakes, Three Sisters and Cuddeback.

 GROUND RULES FOR NO LAUNCH: 1. Malfunction of any SAS channel.

2. Malfunction of inertial platform attitudes.

3. Malfunction of ball nose.

 ALTERNATE SITUATIONS AFTER LAUNCH: 1. If radio or radar fail, proceed as planned.

2. If ball nose fails proceed as planned using g increments instead of a to determine the pull-up maneuvers.

3. If total pitch or roll SAS fails, proceed as planned, do not exceed 8° a.

4. For inadvertent engine shutdown: prior to 39 sec, return to Hidden Hills; 39 to 50 seconds, proceed to Three Sisters; 50 to 65 seconds, proceed to Cuddeback; above 65 seconds, proceed to Edwards - two engine restarts may be attempted in all cases.
