Pace
I was actually thinking of the situation 8 years ago, the raw student who was not yet familiar with all the high tech stuff, and an actual solid lump of model terrain that you could touch and poke at.
I never intended such an 8 X 4foot sheet of ply to be used in the cockpit!
Eventually I'm sure technology will give us the Star Trek Holodeck and we will be able to learn with virtual everything.
No doubt it is possible to fly through these valleys purely head down but when the batt goes pop and the virtual landscape goes a dark shade of black, what then?
It certainly isn't what the training regime should be doing until the basics are there.
