Narrative:

My student and I had just completed our run-up and taxied up to and held short on runway 25. We contacted tower, 'we are holding short runway 25, ready for runway 21L.' tower immediately, responded 'taxi into position and hold.' my student acknowledged, 'taxi into position and hold' and our tail number. We taxied into position looking down final to make sure no one was approaching. Upon our holding, we were asked to clear runway and call tower. The tower had been talking to a plane for runway 21L, and we didn't hear the other plane's tail number for the position and hold. We made the error not asking the tower if those instructions were for us. Tower advised us it wasn't runway incursion because no plane was in danger, or in our area. We could have eliminated the event by reverifying to the tower our taxi and hold short instructions, and waited for him to verify those instructions were for our tail number before complying.

Title: REPLY TO WRONG CALL SIGN PROMOTES A RWY INCURSION WHEN A C172 TRAINING FLT ENTERS RWY 21L WHEN THE TWR HAD CLRED ANOTHER ACFT INTO POS AND HOLD AT LUK, OH.

Narrative: MY STUDENT AND I HAD JUST COMPLETED OUR RUN-UP AND TAXIED UP TO AND HELD SHORT ON RWY 25. WE CONTACTED TWR, 'WE ARE HOLDING SHORT RWY 25, READY FOR RWY 21L.' TWR IMMEDIATELY, RESPONDED 'TAXI INTO POS AND HOLD.' MY STUDENT ACKNOWLEDGED, 'TAXI INTO POS AND HOLD' AND OUR TAIL NUMBER. WE TAXIED INTO POS LOOKING DOWN FINAL TO MAKE SURE NO ONE WAS APCHING. UPON OUR HOLDING, WE WERE ASKED TO CLR RWY AND CALL TWR. THE TWR HAD BEEN TALKING TO A PLANE FOR RWY 21L, AND WE DIDN'T HEAR THE OTHER PLANE'S TAIL NUMBER FOR THE POS AND HOLD. WE MADE THE ERROR NOT ASKING THE TWR IF THOSE INSTRUCTIONS WERE FOR US. TWR ADVISED US IT WASN'T RWY INCURSION BECAUSE NO PLANE WAS IN DANGER, OR IN OUR AREA. WE COULD HAVE ELIMINATED THE EVENT BY REVERIFYING TO THE TWR OUR TAXI AND HOLD SHORT INSTRUCTIONS, AND WAITED FOR HIM TO VERIFY THOSE INSTRUCTIONS WERE FOR OUR TAIL NUMBER BEFORE COMPLYING.
