## Discrepancy

THE CREW REPORTED DURING TAXI OUT, "RT FQMC FAIL" MESSAGE ILLUMINATED ALONG WITH RT WING FUEL QTY "0".  IT EXTINGUISHED AFTER ABOUT 5 SECONDS SHOWING NORMAL READINGS. SHORTLY THEREAFTER "RT FEED TANK LOW" MESSAGE ILLUMINATED AND FEED TANK SHOWED 120LBS. THIS TOO WENT AWAY. TROUBLESHOOTING IDENTIFIED THE FUEL QUANTITY MANAGEMENT COMPUTER AS DEFECTIVE.  INSTALLED A TESTED UNIT, FUNCTIONAL CHECKS WERE SATISFACTORY.
