ATC: "ABC123, is MAG/Omelo/GMH etc on your flightplan?"
ABC123: "stand-by" (or just silence).
Next time why not read your flightplan in advance and know where you're going?
Alt Crz Green, whilst agreeing with all the other points you make, I beg to differ on this one! On a longish sector we don't always know every single waypoint on the flightplan (when we do the FMC route check before departure it's done like the ATC Flight Plan Route with airway designators etc). So sometimes if we are asked (especially if one is not that familiar with the route which is possible) we have to scroll through the route to answer the question. So you might find us saying standby from time to time (obviously there shouldn't be silence) before we can answer the question. Ok I agree that
ideally we should know but it's not always that simple.
Don't know where some of the points you mention come from, especially the "Request" thing on it's own!
