Just started, finished training last month, on my second tour now.
Like Noodles said, no V1 cuts, this is a "light twin". But speeds like a jet, altitudes better than a CRJ!
Procedures are coming together, much emphasis during training on 121 type standardization on all calls and flows, with all us FNG's getting drilled on it.
8 hours minimum in the airplane for initial training, with a little additional as needed. All but one person in our class made it through no problem, we had one person washout( I think). The expectation is that if you meet the minimums, you should know how to fly already, instructors just want to teach the specific characteristics of the Piaggio.
My short exposure and experience with the company has been great so far. Excellent co-workers around PIE, everyone is very upbeat, company has a lot of growth happening,and it sure beats my Comair FO position and my other 135 time.. The flying has much more variety, and the hotels are very nice!
Upgrade looks to be pretty quick (I hope), they make a point of stating that they are not hiring F/O's, you need to meet Capt minimums in order to transition quickly. With the growth that seems to be in the works, there will be a lot of room for advancement.
I rarely post on here, but I have found this a great forum for getting impressions, and info. Just weed out the negative, most of which start to sound like the regionals page.
Feel free to PM if you want any more thoughts/opinions.
