Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Disposition: inline hi craig, although obviously biased i feel that the turbine ivp ie propjet is the way to go. i see right around 300ktas from fl180(39 gph) to fl280(29gph) and typically 32-33 gph at fl250 in my tks deiced propjet. with 146 gallons usable i can comfortably plan for 900 nm and still have over an hour for reserves. yes fuel burn is higher and range slightly less than a piston but when you add climb/descent rates, short field advantages(due to power and prop beta), perceived reliability, the smell of jet a, and the coolness factor it is hard to beat! just my $.02 fwiw, david weinsweig n750dw propjet 233 hrs- still for sale(need a family plane now) but lovin' her 304-633-5221 weinsweigd@gmail.com >>> cj@AwlBiz.com 03/02/2011 9:31 PM >>> If this is posted elsewhere, please point me to the data. The Lancair site says a piston IV-P will do 330 mph (~286 KTAS) at FL240. I'd be interested in what speed and fuel-flow you guys see at sustainable power settings at various altitudes. Most of you flying LOP? I'm going to the APS class this Friday in Ada. How much speed do you lose equipping with the thermal or TKS icing products? Although probably beyond my budget, I'd also be interested in similar data for turbine-powered IVPs. My typical flight is 720 nm Oklahoma City to Phoenix, MEA 13000', prevailing westerlies, 1-2 people and 50 lb stuff. The Mooney M20J does great on non-stop range and economy, but I'm evaluating options for going a lot faster, and preferably with at least inadvertent ice equipment. Currently thinking Mooney Rocket, P-Baron, IV, IVP...? Thoughts on appropriate planes would be welcomed. Craig -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
