CFI........ pick a suitable day, and offer him a free ADVENTURE FLIGHT
It may well be as exciting as a P51D ride for him!
As for the risk models.... just a basic point....of course its safer now, any idiot can see that. 6 A/C max is better than 8 or 10......
The problem is the congestion has been moved outside the "study zone" so its not a problem, of course until some bright spark realises the problems are now far outside the range of the eyes that may be able to help protect them!
