Narrative:

We were cleared to taxi to runway 15R via taxiway P. Taxiway P makes a 50 degree turn to the right as you travel wbound. We missed the turn and crossed the hold short line for runway 15R next to the runway 15R/runway 10 intersection. The ground controller recognized it first and told us to stop. There was no aircraft on runway 15R, and thankfully there was no conflict. Some contributing factors were: 1) first officer on IOE on the plane. 2) we were stopped once by ground control as our ground crew had left a panel open. 3) crew was accomplishing the taxi checklist at that time. We both had our ground taxi charts out and open, and the first officer even commented earlier how easy it would be to make a taxi mistake at this airport. There is absolutely no excuse for this! A pilot needs to know exactly where he is at all times on the ground or stop and find out! I saw the flashing hold short lines coming up and I even made the comment that I would normally have the first officer verify that we are cleared to cross a runway, but I 'knew' we were ok because we were watching a B737 land towards us on the parallel runway I thought was runway 15R and turned out to be runway 10. Better runway identify signs might help. However, I am rededicating myself to not just have the airport diagram out, but to follow it closely! I am going back to double-checking with ground control before crossing any runway. Sometimes they sound a little annoyed when we ask again, but this could have been a tragic accident!

Title: A TXWY AND RWY INCURSION WHEN AN MD80 CHK PLT AND HIS IOE FO FAIL TO NEGOTIATE THE R TURN ON TXWY P AND ALMOST ENTER THE CONFINES OF RWY 15 AT BWI, MD.

Narrative: WE WERE CLRED TO TAXI TO RWY 15R VIA TXWY P. TXWY P MAKES A 50 DEG TURN TO THE R AS YOU TRAVEL WBOUND. WE MISSED THE TURN AND CROSSED THE HOLD SHORT LINE FOR RWY 15R NEXT TO THE RWY 15R/RWY 10 INTXN. THE GND CTLR RECOGNIZED IT FIRST AND TOLD US TO STOP. THERE WAS NO ACFT ON RWY 15R, AND THANKFULLY THERE WAS NO CONFLICT. SOME CONTRIBUTING FACTORS WERE: 1) FO ON IOE ON THE PLANE. 2) WE WERE STOPPED ONCE BY GND CTL AS OUR GND CREW HAD LEFT A PANEL OPEN. 3) CREW WAS ACCOMPLISHING THE TAXI CHKLIST AT THAT TIME. WE BOTH HAD OUR GND TAXI CHARTS OUT AND OPEN, AND THE FO EVEN COMMENTED EARLIER HOW EASY IT WOULD BE TO MAKE A TAXI MISTAKE AT THIS ARPT. THERE IS ABSOLUTELY NO EXCUSE FOR THIS! A PLT NEEDS TO KNOW EXACTLY WHERE HE IS AT ALL TIMES ON THE GND OR STOP AND FIND OUT! I SAW THE FLASHING HOLD SHORT LINES COMING UP AND I EVEN MADE THE COMMENT THAT I WOULD NORMALLY HAVE THE FO VERIFY THAT WE ARE CLRED TO CROSS A RWY, BUT I 'KNEW' WE WERE OK BECAUSE WE WERE WATCHING A B737 LAND TOWARDS US ON THE PARALLEL RWY I THOUGHT WAS RWY 15R AND TURNED OUT TO BE RWY 10. BETTER RWY IDENT SIGNS MIGHT HELP. HOWEVER, I AM REDEDICATING MYSELF TO NOT JUST HAVE THE ARPT DIAGRAM OUT, BUT TO FOLLOW IT CLOSELY! I AM GOING BACK TO DOUBLE-CHKING WITH GND CTL BEFORE XING ANY RWY. SOMETIMES THEY SOUND A LITTLE ANNOYED WHEN WE ASK AGAIN, BUT THIS COULD HAVE BEEN A TRAGIC ACCIDENT!
