## Discrepancy

GYRO LIGHT ILLUMINATED AND ZERO VACUUM INDICATED.  WITHIN A MATTER OF SECONDS, AUTOPILOT COMMANDS FULL NOSE-UP TRIM AND FULL-UP ELEVATOR.  AUTOPILOT STILL PASSES SELF-TEST.  SUBMITTER STATED AUTOPILOT SHOULD HAVE A DISCONNECT IN RELATION TO GYROS LIGHT AND SHOULD CONTROL TRIM MUCH SLOWER AND WITH AN AUDIBLE WARNING.
