AN ACR PIC WAS CONCERNED THAT HE MAY HAVE BEEN INSTRUCTED BY THE TWR TO TAXI AROUND AN ACFT ON A RAMP SECTION AND NOT ON A TXWY.

Narrative

FLT WAS CLRED TO TAXI TO RWY 22L VIA TXWY Y. PRIOR TO REACHING THE APCH END OF RWY 22L; WE WERE #2 BEHIND A REGIONAL JET STOPPED ON TXWY Y. SWITCHING TO THE TWR FREQ; WE ADVISED READY IN SEQUENCE FOR TKOF. TWR ADVISED THAT THE REGIONAL JET WAS NOT READY -- WE WOULD BE #1. THE TWR INSTRUCTED US TO MANEUVER AROUND TO THE R AND PROCEED AHEAD OF THE REGIONAL JET. DIRECTLY TO THE R AND AHEAD OF OUR POS WAS A PAVED AREA COVERED WITH A LIGHT SNOW COATING. WE CONFIRMED WITH THE TWR THAT WE WERE TO TAXI OVER THAT AREA. THE TWR CONFIRMED THAT WAS CORRECT; AND WE PROCEEDED AS INSTRUCTED WITHOUT INCIDENT. AFTER DEP AND REACHING FINAL CRUISE ALT; I CONSULTED THE TAXI CHART ONCE AGAIN. I FOUND IT QUESTIONABLE THAT A PORTION OF THE AREA THE TWR HAD US TAXI ON MAY OR MAY NOT; HAVE BEEN CONSIDERED A TAXI AREA. ALTHOUGH I AM CERTAIN; (OTHER THAN WE MAY HAVE TAXIED ON A PORTION OF THAT RAMP NOT CONSIDERED FOR TAXI) THAT THERE WAS NO INCIDENT. IN THE FUTURE; TAXI INSTRUCTIONS THAT MAY SOUND OR LOOK SUSPICIOUS; SHALL BE QUESTIONED THOROUGHLY TO PREVENT A CASE OF CTLR INDUCED ERROR.
