I just received my waiver about a month ago. My ground school training was with the AMT series of engines. When I received my waiver it said that I could operate ANY of the auto start turbines currently on the approved list. It specified that I could not operate the manual start variety, specifically naming all of the JPX family and the little Golden West turbine. (Which is ironic---these were the two turbines that I cut my teeth on before any such thing as a turbine waiver.) Didn't prior turbine waivers specify that you could only operate the turbine types that you were ground schooled on? If this is so, then it would appear that the AMA is leaning toward a "streamlining" of the turbine waiver system---perhaps making things easier for the potential turbine pilot but still requiring the necessary show of skills?
