Purpose of VOR tuning all the way while flying?
Apologies for the silly question firstly, but how important is it to us that the aircraft keeps auto tuning itself to VOR's?
I understand at take off you have to have your VOR tuned to see if you're on the right radial etc while using the SID on the departure plate.
Once you're going according to you flight plan, what good is VOR tuning at this point?
You are going to be flying the magnetic tracks given in your flight plan to your way points, but why do you need the VORs tuned?
Again sorry for the silly questions, but i'm very confused with this, can somebody explain to me how it works please.
