CL65 CREW HAD A RWY INCURSION AT CAK.

Narrative

WE WERE ROLLING OUT AFTER LNDG ON RWY 19 AT CAK. TWR CTLR TOLD US TO TURN L AND TAXI TO GATE. WE WERE AT THE INTXN OF RWY 19 AND RWY 14. I TURNED OFF RWY 19 ONTO RWY 14; ASSUMING THIS WAS OK WITH THE TWR INSTRUCTIONS. THIS SEEMED THE APPROPRIATE ACTION SINCE 2 OTHER ACFT WERE ON FINAL TO RWY 19 AND I THOUGHT IT BEST TO EXIT SOONER THAN LATER. UNFORTUNATELY; THE TWR CTLR THOUGHT OTHERWISE. WHEN I TURNED ONTO RWY 14; HE MADE THE STATEMENT THAT I WAS ON A RWY NOT A TXWY. I STATED THAT I THOUGHT IT WAS OK SINCE IT WAS NOT AN ACTIVE NOR NOTAMED CLOSED AND THAT HIS INSTRUCTIONS ALLOWED IT. HE STATED THAT AN ACFT IS TO EXIT ONTO THE FIRST AVAILABLE TXWY. I APOLOGIZED AND STATED THAT I THOUGHT THIS WAS OK DUE TO THE CLRNC I HAD. WE CONTINUED OUR TAXI TO THE GATE. I FEEL THAT IN THIS ATC ENVIRONMENT TODAY THAT WE ARE CONSTANTLY PUSHED TO EXIT THE ACTIVE ASAP. SPEND AS LITTLE TIME AS POSSIBLE ON THE ACTIVE RWY IS THE THEME AT MOST ARPTS. I BELIEVE IT WOULD BE VERY HELPFUL AND IMPROVE SAFETY IF AN EXIT TXWY PREFERENCE IS GIVEN IN THE INSTRUCTIONS. IN THIS CASE; THERE IS ONLY 1 MORE ALTERNATIVE AND THAT IS THE TXWY AT THE END OF THE RWY. I FLY INTO THIS ARPT FREQUENTLY AND IT SEEMS THAT ALL THE OTHER CTLRS WANT ME TO EXIT ONTO RWY 14. I ASSUMED IT WAS SOP AT THIS FACILITY; BUT APPARENTLY NOT FOR THIS GENTLEMAN. IT WOULD SEEM SIMPLE ENOUGH TO ISSUE THE CLRNC AS 'EXIT AT THE END AND TAXI TO THE GATE' IF RWY 14 IS NOT AN OPTION. THIS RWY WAS NOT IN USE AT THE TIME. I CALLED GND AFTER PARKING AT THE GATE. THERE WAS ANOTHER CTLR COMING ON DUTY AND HE INFORMED ME THAT THE CTLR'S SHIFT (THE CTLR THAT I WANTED TO TALK TO) HAD ENDED AND HE HAD LEFT. THE CTLR TOLD ME THAT NORMALLY THEY USE RWY 14 FOR EXITING ACFT AND WAS UNSURE WHY THE PREVIOUS CTLR DID NOT. PERHAPS THIS EXPLAINS SOME OF IT; AS THE CTLR MAY HAVE BEEN TIRED AT THE END OF HIS SHIFT. THIS FACILITY DOES COMBINE GND; TWR; AND LCL RADAR AT TIMES. I REMEMBER THAT WE WERE CLRED TO LAND ON APCH FREQ. I WOULD THINK THAT EVERY FACILITY HAS AN SOP FOR ITS OPS. ALTHOUGH THE CLRNC WAS TECHNICALLY CORRECT; WE MISUNDERSTOOD IT DUE TO OUR FAMILIARITY WITH THIS ARPT AND WITNESSING HOW TFC WAS HANDLED BY OTHER CTLRS HERE. VAGUE; TECHNICALLY CORRECT INSTRUCTIONS ARE NOT THE WAY TO ENHANCE SAFETY AND IMPROVE THE EFFICIENCY OF OUR AIRSPACE SYS. A CREW DOES NOT NEED TO WASTE TIME WONDERING IF THIS IS A TEST OF THE RULE BOOK. A CLRNC SHOULD LEAVE NO DOUBT AS TO WHAT THE CTLR NEEDS OR DESIRES. INSTRUCTIONS THAT CLRLY CONVEY THE DESIRED OUTCOME TO ENHANCE SAFETY AND IMPROVE THE PERFORMANCE OF OUR AIRSPACE SYS. SUPPLEMENTAL INFO FROM ACN 541679: THE CTLR AT THAT TIME CALLED US BACK AND ASKED US WHY DID WE TAXI OVER RWY 14/32; AND WE EXPLAINED THAT WE GOT OUT RWY 19 ON THE FIRST AVAILABLE EXIT WHICH HAPPENS TO BE RWY 14/32. WE APOLOGIZED AND WE TOLD HIM THAT OTHER PREVIOUS TIMES BEFORE WE HAD BEEN CLRED THAT WAY TO THE GATE.
