Lol, that's a bit mean chevvron - they ask you for a true bearing FROM you, and you give them a magnetic bearing TO you and the variation? Not much mental arithmetic there then?
Seriously though, if your kit will show QDM surely it will show QDR, are you allowed to apply variation yourselves and then give the pilot a QTE that they asked for?
I would think if they actually needed to ask for a QTE then they are trying to plot position - which by default suggests that they don't know quite where they are (maybe completely lost) - so a touch of Disney magic would be welcomed (cast members going the extra mile for guest satisfaction).
I'ts a shame that VDF is now being written with the letters GPS.
FlyingGiant - should that call not be to Exampleton Homer, not Approach?
