Narrative:

Ground control cleared us to 'taxi to runway 19R via taxiway F, hold short of runway 25R.' we taxied from the GA ramp to runway 19R on taxiway F. Upon arrival, at the departure end of runway 19R, ground informed us that we had crossed an active runway (25R). Taxiway F, on taxi diagram, in united states terminal procedures, east control, volume 3, march/thu/95, page 265, does not show runway 7L/25R as crossing taxiway F. The runway begins south of the taxiway. I did not see any runway markings or hold lines while en route to the end of runway 19R on taxiway F. I believe the proper clearance issued, should have been: hold short of the extended centerline of runway 7L on taxiway F (if that was ground control's desire). When you are not familiar with an airport, you rely on taxi diagrams and airport markings to remain clear of active runways. I do not believe that taxiway F and runway 7L are marked clearly enough to give flcs adequate information without special instructions. Callback conversation with reporter revealed the following information: the captain states that because of the short taxi route, the before takeoff checklist had been completed prior to taxiing from the ramp. This gave the first officer freedom to be heads-up in the taxi phase, however, he did not have the published diagram.

Title: A CORP FLC FAILED TO HOLD SHORT OF AN ACTIVE RWY, CITING POOR MARKINGS, AND AN INSUFFICIENT ARPT DIAGRAM. MULTIPLE RWYS IN USE.

Narrative: GND CTL CLRED US TO 'TAXI TO RWY 19R VIA TXWY F, HOLD SHORT OF RWY 25R.' WE TAXIED FROM THE GA RAMP TO RWY 19R ON TXWY F. UPON ARR, AT THE DEP END OF RWY 19R, GND INFORMED US THAT WE HAD CROSSED AN ACTIVE RWY (25R). TXWY F, ON TAXI DIAGRAM, IN UNITED STATES TERMINAL PROCS, E CTL, VOLUME 3, MARCH/THU/95, PAGE 265, DOES NOT SHOW RWY 7L/25R AS XING TXWY F. THE RWY BEGINS S OF THE TXWY. I DID NOT SEE ANY RWY MARKINGS OR HOLD LINES WHILE ENRTE TO THE END OF RWY 19R ON TXWY F. I BELIEVE THE PROPER CLRNC ISSUED, SHOULD HAVE BEEN: HOLD SHORT OF THE EXTENDED CTRLINE OF RWY 7L ON TXWY F (IF THAT WAS GND CTL'S DESIRE). WHEN YOU ARE NOT FAMILIAR WITH AN ARPT, YOU RELY ON TAXI DIAGRAMS AND ARPT MARKINGS TO REMAIN CLR OF ACTIVE RWYS. I DO NOT BELIEVE THAT TXWY F AND RWY 7L ARE MARKED CLRLY ENOUGH TO GIVE FLCS ADEQUATE INFO WITHOUT SPECIAL INSTRUCTIONS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAPT STATES THAT BECAUSE OF THE SHORT TAXI RTE, THE BEFORE TKOF CHKLIST HAD BEEN COMPLETED PRIOR TO TAXIING FROM THE RAMP. THIS GAVE THE FO FREEDOM TO BE HEADS-UP IN THE TAXI PHASE, HOWEVER, HE DID NOT HAVE THE PUBLISHED DIAGRAM.
