Narrative:

This was my first flight after training on the medium large transport. It was a ferry flight after the airplane had just been released by maintenance. The FMC's were in independent operation and would not talk to each other. On liftoff, the EFIS dropped the departure course (dca 185 degrees). While we were raising the gear and setting up the cockpit for manual navigation (VOR) we received a full blown wind shear alert (which we later determined to be a nuisance alert). While the wind shear alert was going off, departure control reclred us from 3000 ft to 5000 ft and turn to 050 degrees to intercept the 097 degree (?) radial off aml. We were in a right turn to intercept the VOR course we had just tuned and just continued around. The departure controller called us leveling 5000 ft and said that he had wanted a l-hand turn. Contributing factors: FMC data dump, wind shear nuisance alert, multiple clearance.

Title: WHILE DISTRACTED BY A FALSE WARNING, FLC TURNED THE WRONG WAY TO THEIR ASSIGNED HDG.

Narrative: THIS WAS MY FIRST FLT AFTER TRAINING ON THE MLG. IT WAS A FERRY FLT AFTER THE AIRPLANE HAD JUST BEEN RELEASED BY MAINT. THE FMC'S WERE IN INDEPENDENT OP AND WOULD NOT TALK TO EACH OTHER. ON LIFTOFF, THE EFIS DROPPED THE DEP COURSE (DCA 185 DEGS). WHILE WE WERE RAISING THE GEAR AND SETTING UP THE COCKPIT FOR MANUAL NAV (VOR) WE RECEIVED A FULL BLOWN WIND SHEAR ALERT (WHICH WE LATER DETERMINED TO BE A NUISANCE ALERT). WHILE THE WIND SHEAR ALERT WAS GOING OFF, DEP CTL RECLRED US FROM 3000 FT TO 5000 FT AND TURN TO 050 DEGS TO INTERCEPT THE 097 DEG (?) RADIAL OFF AML. WE WERE IN A R TURN TO INTERCEPT THE VOR COURSE WE HAD JUST TUNED AND JUST CONTINUED AROUND. THE DEP CTLR CALLED US LEVELING 5000 FT AND SAID THAT HE HAD WANTED A L-HAND TURN. CONTRIBUTING FACTORS: FMC DATA DUMP, WIND SHEAR NUISANCE ALERT, MULTIPLE CLRNC.
