## Discrepancy

(CAN) ALTITUDE DIGITIZER COMES ON AFTER 3 MINUTES, BUT THEN CLIMBS TO 500 FEET ABOVE ACTUAL ALTITUDE AND THEN SLOWLY RETURNS TO ACTUAL ALTITUDE.  AFTER 10 MINUTES THIS UNIT FUNCTIONS CORRECTLY. HOWEVER, THE OPERATOR OF THIS ROTORCRAFT HAS BEEN REQUESTED BY ATC TO SHUT OFF THIS UNIT UNTIL THE ROTORCRAFT IS CLEAR OF THE CONTROL ZONE.
