that's why emphasis is placed on sorting the problem out earlier rather than later.
Ok - scenario time.
You (not you personally, just a generic "you") realise you're unsure of your position, you start thinking of all the things you were taught, but before you get the chance to put them into action you notice the big runway, big terminal, big aircraft parked outside it.
You don't know where it is, and so you've just gone from "unsure of position" to "lost" very quickly (if you still want to say unsure of position then fine, but the solution is still going to be the same) - who you going to call? Are you going to ask someone for a VDF bearing? Are you going to stare at the chart and then start panicking as to who you're going to call? Are you going to start dialling up VOR's and trying to work out where you are?
NO - YOU'RE IN THE $HIT AND YOU NEED TO SORT IT SHARPISH.
