C-150 PERFORMS AN UNAUTH TKOF.

Narrative

A CFI AN I WERE HOLDING ON TXWY CHARLEY FOR A DEP USING THE FULL LENGTH OF RWY 4R IN HONOLULU INTL ARPT. WE WERE IN A CESSNA 150 WAITING FOR AN ACR 737 TO LAND. THE CFI WAS IN THE L SEAT AND OPERATING THE RADIOS. I WAS ACCOMPANYING CFI THAT FRIDAY OF MAY MORNING ON A FISH SPOTTING FLT. AFTER THE 737 PASSED BY; CFI ASKED IF I WANTED TO DO THE TKOF. I WAS IN AN UNFAMILIAR TXWY; BUT TOLD HIM THAT I WOULD LIKE TO AND SO WE AGREED ON THAT. I CANNOT RECALL THE EXACT DIALOGUE BTWN OUR ACFT AND THE TWR BEFORE THE TKOF; BUT I BELIEVE THIS IS WHAT WAS SAID AFTER THE ACR 737 HAD LANDED. TWR: CESSNA; TAXI; POS AND HOLD RWY 4R; CAUTION WAKE TURB. CFI: CESSNA; POS AND HOLD RWY 4R. WHILE THE CFI WAS TALKING WITH THE TWR; I MANEUVERED THE ACFT ONTO THE RWY AND WENT THROUGH THE BEFORE TKOF CHKLIST. I THEN BEGAN THE TKOF ROLL. WHEN WE WERE AIRBORNE; TWR TOLD US THAT WE HAD NOT BEEN CLRED FOR TKOF. EVEN THOUGH I WAS NOT TALKING ON THE RADIO; I SHOULD HAVE PAID MORE ATTN TO OUR SIT. I'M USED TO HEARING FROM TWR 'CLRED FOR TKOF; CAUTION WAKE TURB.' I AM NOT USED TO HEARING 'POS AND HOLD; CAUTION WAKE TURB.' I MISHEARD OUR MESSAGE AS A TKOF CLRNC; CAUTION WAKE TURB. ANOTHER MISTAKE ON MY PART WAS CONDUCTING THE BEFORE TKOF CHKLIST WHILE CFI COMMUNICATED WITH TWR. THIS COMBINED WITH COMPLACENCY FROM KNOWING I WAS FLYING WITH A CFI; AND POOR COCKPIT RESOURCE MGMNT CONTRIBUTED TO MY DEV. SUPPLEMENTAL INFO FROM ACN 271171: I AGREED TO PARTICIPATE IN A FLT WITH A COMMERCIAL PLT. TAXIED THE ACFT TO TXWY 4 R FULL LENGTH. AT THIS POINT I TOLD THE OTHER PLT THAT HAVE THE FLT CTLS AND THE AIRPLANE; AT THIS POINT OTHER PLT WAS THE PIC OF THE ACFT. PROCEEDED TO RWY AND BEGAN TKOF DEP. OTHER PLT CALLED THE TWR WHEN ON THE GND AND THE TWR STATED THAT THEY WANTED TO KNOW WHO HAD THE CTLS OF THE ACFT; OTHER PLT STATED THAT HE HAD THE FLT CTLS ON THE DEP. THE TWR THEN STATED THAT ALL THEY NEED IS HIS ADDRESS BECAUSE HE WAS FLYING THE AIRPLANE WHEN THE INCIDENT OCCURRED. I WAS NOT THE PIC IN THE ACFT AT THE TIME OF THE INCIDENT.
