Narrative:

It was a calm; clear; full moon night with unlimited visibility. A student pilot and I were in the airport traffic pattern doing multiple stop-and-goes. My student just finished making an announcement that he was on left crosswind for runway 5 when I heard air carrier Y announce that they were going to be taxiing to runway 2. My student then announced when he was on left downwind for runway 5 and I could see the air carrier taxiing toward the approach end of runway 2. My student then announced when he was on left base and turning final for runway 5; and I could still see the air carrier getting closer to the approach end of runway 2. While we were on final for runway 5; air carrier Y announced that they were taking the active runway 2. I wanted to make sure they knew we were on final for runway 5 and was hoping they would not mind us doing a stop-and-go before they took off. So I got on the radio and said; 'kahului traffic; cessna XXX on final runway 5; we would like to do a stop-and-go and then go over to right traffic runway 2; if that's ok with you guys.' air carrier Y responded back saying something to the effect of 'sure; yeah; ok' (not the exact words). We touched down on the beginning part of runway 5 and were slowing down. In an effort to not make the air carrier wait too long; we applied the power to take off before coming to a complete stop. After we were airborne and past the main terminal (which blocks the view of the approach end of runway 5 from runway 2 and vice versa); I noticed that the air carrier jet was also airborne! I placed the airplane in a left turn (an early left crosswind for runway 5) and announced that I was turing left on the radio. While back on left downwind to runway 5; air carrier Y came on the radio and said something like 'you did say stop-and-go right?' I responded back with; 'yes I did say stop-and-go; sorry about the confusion; have a safe flight.' there was no response back from air carrier Y. In retrospect; I think that when I said 'stop-and-go;' the air carrier Y pilot must have thought I was going to stop on runway 5 and then wait for them to take off from runway 2; before I took off again on runway 5. My perception was that they were going to get into position and hold while we did our stop-and-go. Without a doubt; I should have made sure words were said between me and the other aircraft that clarified who was going to be airborne first. A simple clarification like that would have prevented that close call from ever happening.

Title: C172 ON NIGHT TRAINING FLT HAD UNCTLED TFC PATTERN SEPARATION PROB WITH B737 DEPARTING XING RWY DURING A STOP-AND-GO LNDG.

Narrative: IT WAS A CALM; CLR; FULL MOON NIGHT WITH UNLIMITED VISIBILITY. A STUDENT PLT AND I WERE IN THE ARPT TFC PATTERN DOING MULTIPLE STOP-AND-GOES. MY STUDENT JUST FINISHED MAKING AN ANNOUNCEMENT THAT HE WAS ON L XWIND FOR RWY 5 WHEN I HEARD ACR Y ANNOUNCE THAT THEY WERE GOING TO BE TAXIING TO RWY 2. MY STUDENT THEN ANNOUNCED WHEN HE WAS ON L DOWNWIND FOR RWY 5 AND I COULD SEE THE ACR TAXIING TOWARD THE APCH END OF RWY 2. MY STUDENT THEN ANNOUNCED WHEN HE WAS ON L BASE AND TURNING FINAL FOR RWY 5; AND I COULD STILL SEE THE ACR GETTING CLOSER TO THE APCH END OF RWY 2. WHILE WE WERE ON FINAL FOR RWY 5; ACR Y ANNOUNCED THAT THEY WERE TAKING THE ACTIVE RWY 2. I WANTED TO MAKE SURE THEY KNEW WE WERE ON FINAL FOR RWY 5 AND WAS HOPING THEY WOULD NOT MIND US DOING A STOP-AND-GO BEFORE THEY TOOK OFF. SO I GOT ON THE RADIO AND SAID; 'KAHULUI TFC; CESSNA XXX ON FINAL RWY 5; WE WOULD LIKE TO DO A STOP-AND-GO AND THEN GO OVER TO R TFC RWY 2; IF THAT'S OK WITH YOU GUYS.' ACR Y RESPONDED BACK SAYING SOMETHING TO THE EFFECT OF 'SURE; YEAH; OK' (NOT THE EXACT WORDS). WE TOUCHED DOWN ON THE BEGINNING PART OF RWY 5 AND WERE SLOWING DOWN. IN AN EFFORT TO NOT MAKE THE ACR WAIT TOO LONG; WE APPLIED THE PWR TO TAKE OFF BEFORE COMING TO A COMPLETE STOP. AFTER WE WERE AIRBORNE AND PAST THE MAIN TERMINAL (WHICH BLOCKS THE VIEW OF THE APCH END OF RWY 5 FROM RWY 2 AND VICE VERSA); I NOTICED THAT THE ACR JET WAS ALSO AIRBORNE! I PLACED THE AIRPLANE IN A L TURN (AN EARLY L XWIND FOR RWY 5) AND ANNOUNCED THAT I WAS TURING L ON THE RADIO. WHILE BACK ON L DOWNWIND TO RWY 5; ACR Y CAME ON THE RADIO AND SAID SOMETHING LIKE 'YOU DID SAY STOP-AND-GO RIGHT?' I RESPONDED BACK WITH; 'YES I DID SAY STOP-AND-GO; SORRY ABOUT THE CONFUSION; HAVE A SAFE FLT.' THERE WAS NO RESPONSE BACK FROM ACR Y. IN RETROSPECT; I THINK THAT WHEN I SAID 'STOP-AND-GO;' THE ACR Y PLT MUST HAVE THOUGHT I WAS GOING TO STOP ON RWY 5 AND THEN WAIT FOR THEM TO TAKE OFF FROM RWY 2; BEFORE I TOOK OFF AGAIN ON RWY 5. MY PERCEPTION WAS THAT THEY WERE GOING TO GET INTO POS AND HOLD WHILE WE DID OUR STOP-AND-GO. WITHOUT A DOUBT; I SHOULD HAVE MADE SURE WORDS WERE SAID BTWN ME AND THE OTHER ACFT THAT CLARIFIED WHO WAS GOING TO BE AIRBORNE FIRST. A SIMPLE CLARIFICATION LIKE THAT WOULD HAVE PREVENTED THAT CLOSE CALL FROM EVER HAPPENING.
