I've flown the A, A+, and A++.
I found that the A+ didn't perform any better than the A. At 30 C the A+ N1d out at about the same Q as the A Temped out. Now the A++ was a real performer it Torqued out at 30 C.
Midniteblues: The Initial course is probably around $20K US. The last time I was on the recurrent A [2001] it was $6,995 USD.
