i have been given the Flight Safety manual on the s550, so this should be enough as far as simple POH info, but i'm looking for more information on the quirks of the aircraft. how is it in icing?, what altitudes seem to be the best combination of speed and economy?, any maintenance issues or things to pay particularly close attention to. you know, things that only people who have experience with the aircraft know. myself and the other pilot will essentially be running the flight department, (including maintenance), so i want as much info as i can get. thanks again for your replies.
