Do you have your nav students take a whiz wheel and ruler in the air with them?
What is the procedure you advocate for diverting to an unplanned alternate airfield lets say due to a blocked single runway?
And with all due respect, all this talk of low level nav at 420knots and vulcans has absolutley no relevance here, lets base the rest of this thread on a Cessna 152/172 shall we.
head down nav planning in flight or trying to do complex mental arithmetic in flight is bollox imho
