Narrative:

Controller was working clearance, ground, tower, and departure/approach. He cleared me to 'taxi in position and hold' runway 25 at juliet. He proceeded to work previously departed aircraft. While I was still in position and holding, cleared aircraft holding short of runway 25 at juliet behind me for takeoff. Luckily, aircraft saw me on runway and I was able to inform tower of my position in time. Controller apologized and said he thought he had already cleared me for takeoff (he hadn't!). He then did clear me for takeoff and instructed other aircraft to position and hold. I fly into jax 5 nights per week. They always have 1 controller 'wearing all the hats' at time of night (as does mco, dab, and tpa). The controller has always been very professional, eager to help, and done an excellent job. I believe that on this occasion he had, as he stated, thought that he had cleared me for takeoff. Contributing to this honest human mistake was the fact that he was handling 2 aircraft requesting takeoff clearance (me included), 1 just having departed, 1 on final to 'intersecting' runway, and a commuter shooting multiple practice approachs and lndgs.

Original NASA ASRS Text

Title: SMT AIR TAXI IN POS AND HOLD FOR INTXN TKOF WHEN LCL CLRS ANOTHER ACFT FOR TKOF.

Narrative: CTLR WAS WORKING CLRNC, GND, TWR, AND DEP/APCH. HE CLRED ME TO 'TAXI IN POS AND HOLD' RWY 25 AT JULIET. HE PROCEEDED TO WORK PREVIOUSLY DEPARTED ACFT. WHILE I WAS STILL IN POS AND HOLDING, CLRED ACFT HOLDING SHORT OF RWY 25 AT JULIET BEHIND ME FOR TKOF. LUCKILY, ACFT SAW ME ON RWY AND I WAS ABLE TO INFORM TWR OF MY POS IN TIME. CTLR APOLOGIZED AND SAID HE THOUGHT HE HAD ALREADY CLRED ME FOR TKOF (HE HADN'T!). HE THEN DID CLR ME FOR TKOF AND INSTRUCTED OTHER ACFT TO POS AND HOLD. I FLY INTO JAX 5 NIGHTS PER WK. THEY ALWAYS HAVE 1 CTLR 'WEARING ALL THE HATS' AT TIME OF NIGHT (AS DOES MCO, DAB, AND TPA). THE CTLR HAS ALWAYS BEEN VERY PROFESSIONAL, EAGER TO HELP, AND DONE AN EXCELLENT JOB. I BELIEVE THAT ON THIS OCCASION HE HAD, AS HE STATED, THOUGHT THAT HE HAD CLRED ME FOR TKOF. CONTRIBUTING TO THIS HONEST HUMAN MISTAKE WAS THE FACT THAT HE WAS HANDLING 2 ACFT REQUESTING TKOF CLRNC (ME INCLUDED), 1 JUST HAVING DEPARTED, 1 ON FINAL TO 'INTERSECTING' RWY, AND A COMMUTER SHOOTING MULTIPLE PRACTICE APCHS AND LNDGS.
