If you gentleman permit me to get back to the initial question raised by the originating post of this thread, I would like to ask a quick question about it, if I may.
So I'm sitting on a rwy (no matter where!!!!!, US/UK/South Pole/Tibette) that I know, provided by my most recent airport diagram/chart, is crossed by another rwy, I'm lined up, ready and waiting for my T/O clearance, and I also know, either by R/T or simple observation, that the other rwy is or could be in use, and I don't feel comfortable with that situation... what should I do after been given the clearance (and before "pushing thrust levers into EICAS") ?
Should I trust ATC blindly and go for it?
Should I wait for a second or two in order to give some time for a possible correction to be made by ATC?
Should I ask the controller to repeat the last transmission?
