Then why do the flight in the first place if you could do it visually?
Because, in the words of an instructor, I need to stretch myself & get useful hourbuilding in. I could have done the visual flight, but I don't feel I would have gotten as much out of it compared to the way I did it.
VORS can and will pack up at a moments notice. And let me make this perfectly clear there is NO PLACE in IFR navigation for dead reckoning. That is just a disaster waiting to happen.
I accept that you're far better placed/qualified/experienced to judge that than me - but if that's the case, if you're relying on VORs over DR, how come a GPS backup isn't mandatory for IFR flight? (If it actually is, I apologise!)
