Narrative:
During a visual approach using ILS information to panc, runway 6R, we received a white-boxed 'flaps' alert. This indicates the flaps are not in the landing position. We checked the confign synoptic which showed the inboard flaps were at 35 degrees, our desired landing confign, while the outboard flaps were at 31 degrees. We went around and performed the flight manual procedure. This did not improve the situation, so with the flaps set at 35 degrees (again with the outboard flaps at 31 degrees) we landed uneventfully on runway 6R at anchorage. Maintenance performed their checks and adjusted several limiters.

Title: AN MD11 EXECUTED A GAR DUE TO INCORRECT FLAP POS FOR LNDG. UNABLE TO CORRECT OUTBOARD FLAP POS, LANDED UNEVENTFULLY.
Narrative: DURING A VISUAL APCH USING ILS INFO TO PANC, RWY 6R, WE RECEIVED A WHITE-BOXED 'FLAPS' ALERT. THIS INDICATES THE FLAPS ARE NOT IN THE LNDG POS. WE CHKED THE CONFIGN SYNOPTIC WHICH SHOWED THE INBOARD FLAPS WERE AT 35 DEGS, OUR DESIRED LNDG CONFIGN, WHILE THE OUTBOARD FLAPS WERE AT 31 DEGS. WE WENT AROUND AND PERFORMED THE FLT MANUAL PROC. THIS DID NOT IMPROVE THE SIT, SO WITH THE FLAPS SET AT 35 DEGS (AGAIN WITH THE OUTBOARD FLAPS AT 31 DEGS) WE LANDED UNEVENTFULLY ON RWY 6R AT ANCHORAGE. MAINT PERFORMED THEIR CHKS AND ADJUSTED SEVERAL LIMITERS.
