I've read this thread from page one.
So much information, so little wisdom.
Change things is the cry...old ways don't work.
Pilots screw up? Or are they lead down the garden path to disaster by charting and procedures and gadgets galore.
Well, why not do what we did with circling approaches for part 121 airliners...all have to be done in basic VFR/VMC.
Why not make all NON PRECISION approaches to(circling or straight in or modified straight in) 1000 feet and 3 miles visibility. (or more in special situations).
There, now we don't have to monkey with the gadgets and other things.
And the bean counters will have to say: hmmm...planes not getting in, we better invest in a precision approach at that airport.
