Narrative

THERE IS AN ISSUE WITH F100 MEL ITEM XX REGARDING ENG 2/2 OIL PRESSURE INDICATION ON MFDU. UPON RECEIVING THIS INDICATION AND COMPLYING WITH THE APPROPRIATE CHKLIST; WE RECEIVED AN OIL PRESSURE LIMIT RED WARNING AND ASSOCIATED AURAL ALERT. WE RETURNED TO THE GATE AND HAD MAINT TEST APPROPRIATELY AND ENDED UP PLACARDING THE SENSOR AND RELYING ON THE BACKUP SYS AS PER MEL XX. MAINT ADVISED THAT WE WOULD NOT RECEIVE ANY WARNINGS DUE TO PULLED AND COLLARED CIRCUIT BREAKER. AT HIGH SPD TKOF ROLL WE RECEIVED AMBER THEN RED ALERTS FOR ENG #1 OIL PRESSURE AND OIL PRESSURE LIMIT ACCORDINGLY. ENG CONTINUED TO RUN. I ELECTED TO CONTINUE TO SORT IT OUT IN THE AIR. DURING CLB WE RECEIVED A LIGHT IN THE FUEL HANDLE. THE STANDBY SYS AT NO TIME INDICATED AN ENG OIL PRESSURE PROB AND THE ASSOCIATED ENG RAN FINE IN ALL RESPECTS. WE CONTINUED TO DEST. TECHNICIAN AND DISPATCH WERE CONTACTED AND ADVISED THAT ANOTHER CREW SHOULD NOT BE GIVEN THAT ACFT EVEN THOUGH THE MEL HAD BEEN SATISFIED. EVERY TIME THE THROTTLE POS MOVED BEYOND MINIMUM TKOF POS; THE WARNING CYCLE WOULD REPEAT AND THE LIGHT IN THE FUEL HANDLE WOULD ILLUMINATE. FLCS SHOULD NOT BE SUBJECTED TO EXPECTING THESE CONDITIONS DURING MEL XX DISPATCHED FLTS.
