I just wanted to clarify something. Most Caribbean airports require some sort of a back taxi. However, the “back taxi” command is different from “line up and wait”. For example, at TFFR, a 737 has enough room to take off from the taxiway entrance to the runway. There is no need to back taxi. A 777 on the other hand needs the full length of the runway. So if an ATC like myself says to line up and wait from the taxiway entrance, that means you line up and wait, and DO NOT back taxi. We as ATC’s have a command specifically for back taxi. If we don’t say it, we don’t mean it. Also, we might have the space to clear you for a takeoff from the entrance, but not enough time to have you back taxi before an inbound lands.So, if you are cleared to takeoff or line up and wait, do it from the entrance to the runway, and do not execute a back taxi if not instructed. Thanks!
EDIT: After some debate below, I have decided that, at least for myself, I will instruct all jets to back taxi, while instructing props to take off from the taxiway entrance to the runway. I hope this clears up some confusion and complaints related to realism. I will say this may caused increased delays. Either way, apologies to anyone at TFFR today who felt like the ATC was not up to par. And, no matter what, please continue listening to ATC instructions!
