AA5 PLT TAXIED ON THE WRONG RWY AT ABQ.

Narrative

INCIDENT OCCURRED DURING TAXI TO DEP RWY. I WAS ASSIGNED RWY 8 FOR DEP. RWY 8 AND RWY 12 THRESHOLDS ARE CO-LOCATED FROM THE SAME TXWY AND I WAS S OF THE RWY TAXIING NORTHWARD. RWY 12 IS THE FIRST RWY ONE WILL APCH FOLLOWED BY RWY 8 WHEN TAXIING IN THIS DIRECTION. I DID NOT SEE ANY CLR IDENT OF RWY LOCATION SIGNS ON L SIDE OF TXWY AND THOUGHT I TAXIED FAR ENOUGH PAST THE THRESHOLD OF RWY 12. AS I LINED UP WITH THE RWY CTRLINE I SAW AHEAD OF ME WHAT I MISTOOK TO BE RWY DISTANCE REMAINING SIGNS; BUT WERE ACTUALLY RWY LOCATION SIGNS FOR RWY 12 (YELLOW NUMBERS ON BLACK BACKGROUND). RWY DISTANCE REMAINING SIGNS ARE WHITE NUMBERS ON BLACK BACKGROUND. RWY 8 IS 13000 FT SO I THOUGHT IT WAS POSSIBLE THAT I WAS ON RWY 8 ABOUT 500 FT FROM THE THRESHOLD ON THE ACTIVE SIDE. I WAS IN DOUBT AND DOUBLE-CHKED WITH THE DIRECTIONAL GYROSCOPE AND MAGNETIC COMPASS WHICH CONFIRMED I WAS ALIGNED ON RWY 12. I APPLIED PWR (NOT FULL) IN ORDER TO TURN THE NOSEWHEEL TO TAXI TO RWY 8. TWR AT THAT TIME ADVISED I WAS ON RWY 12 AND TO TAXI TO RWY 8. SUGGEST BETTER SIGNS DENOTING RWYS 8 AND 12 ON AREA JUST TO L OF TXWY. INSTEAD OF JUST NUMBERS ON RWY LOCATION SIGNS; ADD 'RWY' NEXT TO THE NUMBER; IE; 'RWY 12 NOT JUST '12.'
