Narrative:

Tower cleared us from runway 28L to cross runway 28C and contact ground. Prior to the ramp we must also cross runway 32. The ATIS was calling 28L/right and 32 as active prior to approach on ILS 28L. The normal procedure is usually to stay on tower frequency until crossing runway 32. The victor taxiway intersection of runway 32 is only approximately 1500' passed where we crossed 28C. Aircraft were being taxied and parked awaiting further clearance at the departure end of runway 32. While crossing runway 32 at victor taxiway and sure the runway was clear, I switched from tower to ground. Ground cleared us to the ramp at which time I contacted ramp control. They advised us to call the greater pittsburgh tower. Tower believed we should have contacted ground control sooner after crossing 28C. There were no conflicts or other problems. Normally, the ground flow at greater pittsburgh flows smoothly. However, when 28L and 32 are both active some controllers pass off to ground prior to crossing 32 and others after. Standardization would be beneficial. I am hesitant to switch from tower before I know I'm clear of all active runways. If the runway was no longer active that would be nice to know. The problem besides standardization is a slight communications gap. I'm sure in the future it would be wise to question tower, specifically in this case, about the radio changeover point and status of the runway to be crossed.

Title: FLT CROSSED ACTIVE RWY WITHOUT A CLRNC. FLT CREW CROSSED ACTIVE RWY 32 WITHOUT A CLRNC. PLT DEVIATION.

Narrative: TWR CLRED US FROM RWY 28L TO CROSS RWY 28C AND CONTACT GND. PRIOR TO THE RAMP WE MUST ALSO CROSS RWY 32. THE ATIS WAS CALLING 28L/R AND 32 AS ACTIVE PRIOR TO APCH ON ILS 28L. THE NORMAL PROC IS USUALLY TO STAY ON TWR FREQ UNTIL XING RWY 32. THE VICTOR TXWY INTXN OF RWY 32 IS ONLY APPROX 1500' PASSED WHERE WE CROSSED 28C. ACFT WERE BEING TAXIED AND PARKED AWAITING FURTHER CLRNC AT THE DEP END OF RWY 32. WHILE XING RWY 32 AT VICTOR TXWY AND SURE THE RWY WAS CLEAR, I SWITCHED FROM TWR TO GND. GND CLRED US TO THE RAMP AT WHICH TIME I CONTACTED RAMP CTL. THEY ADVISED US TO CALL THE GREATER PITTSBURGH TWR. TWR BELIEVED WE SHOULD HAVE CONTACTED GND CTL SOONER AFTER XING 28C. THERE WERE NO CONFLICTS OR OTHER PROBLEMS. NORMALLY, THE GND FLOW AT GREATER PITTSBURGH FLOWS SMOOTHLY. HOWEVER, WHEN 28L AND 32 ARE BOTH ACTIVE SOME CTLRS PASS OFF TO GND PRIOR TO XING 32 AND OTHERS AFTER. STANDARDIZATION WOULD BE BENEFICIAL. I AM HESITANT TO SWITCH FROM TWR BEFORE I KNOW I'M CLEAR OF ALL ACTIVE RWYS. IF THE RWY WAS NO LONGER ACTIVE THAT WOULD BE NICE TO KNOW. THE PROBLEM BESIDES STANDARDIZATION IS A SLIGHT COMS GAP. I'M SURE IN THE FUTURE IT WOULD BE WISE TO QUESTION TWR, SPECIFICALLY IN THIS CASE, ABOUT THE RADIO CHANGEOVER POINT AND STATUS OF THE RWY TO BE CROSSED.
