Airbus38
"What's so special about a PA28?"
Nothing is special about most PA28's.
I have looked round ravenair's PA38's and like most PA38's and C152's they were not really equipped for IR training, they were significantly different from the Aztec which you would take your test in, no HSI or RMI and significantly slower. I Just meant that the minimum I (ME) would find useful is a PA28 with some similar decent equipment in it.
However as they have the use of an FNPT II it is irrelevant as they are obviously moving forward, they should maybe update their website which currently states 35 or 40 hours in a 38 as part of the IR package.
I can only go off my experience which was a good one but with no Sim.......
