## Discrepancy

PILOT WRITE UP WAS ''STICKS SEVERAL THOUSAND FEET'', CALIBRATION WAS OUT AT -1,000 AND ZERO FEET AND 500 FEET, ENCODER FUNCTIONS PROPERLY, COULD NOT VERIFY OR DUPLICATE STICKING.  ALTIMETER WAS 40 FEET LOW AT -1,000 FEET AND PROGRESSIVELY GOT BETER.  AT +1,000 FEET WAS ZERO ERROR AND WITHIN LIMITS FOR REST OF TEST. (X)
