Narrative:
We had just landed and were waiting to cross runway 13. The PNF queried ground control if we could cross runway 13. The controller responded 'not yet.' I thought the controller responded 'yeah' and taxied forward, across the hold short line. Unsure, I stopped the aircraft prior to runway 13, but the aircraft was past the hold short line at this point. The PNF then radioed for verification of our crossing clearance. The ground controller then responded, 'negative, hold short, well it looks like you've already past the hold short line -- I did not receive clearance from the tower controller until now, you're cleared to cross runway 13.' lessons learned: standard communication phraseology is imperative. The ground controller used nonstandard phraseology ('not yet') and I accepted what I thought to be a clearance to cross an active runway with nonstandard phraseology. Both pilot and controller erred, in my opinion.
Original NASA ASRS Text
Title: LEARJET CREW MISUNDERSTANDS CLRNC GIVEN WITH NON STANDARD PHRASEOLOGY AND STARTS ACROSS RWY WITHOUT CLRNC.
Narrative: WE HAD JUST LANDED AND WERE WAITING TO CROSS RWY 13. THE PNF QUERIED GND CTL IF WE COULD CROSS RWY 13. THE CTLR RESPONDED 'NOT YET.' I THOUGHT THE CTLR RESPONDED 'YEAH' AND TAXIED FORWARD, ACROSS THE HOLD SHORT LINE. UNSURE, I STOPPED THE ACFT PRIOR TO RWY 13, BUT THE ACFT WAS PAST THE HOLD SHORT LINE AT THIS POINT. THE PNF THEN RADIOED FOR VERIFICATION OF OUR XING CLRNC. THE GND CTLR THEN RESPONDED, 'NEGATIVE, HOLD SHORT, WELL IT LOOKS LIKE YOU'VE ALREADY PAST THE HOLD SHORT LINE -- I DID NOT RECEIVE CLRNC FROM THE TWR CTLR UNTIL NOW, YOU'RE CLRED TO CROSS RWY 13.' LESSONS LEARNED: STANDARD COM PHRASEOLOGY IS IMPERATIVE. THE GND CTLR USED NONSTANDARD PHRASEOLOGY ('NOT YET') AND I ACCEPTED WHAT I THOUGHT TO BE A CLRNC TO CROSS AN ACTIVE RWY WITH NONSTANDARD PHRASEOLOGY. BOTH PLT AND CTLR ERRED, IN MY OPINION.
