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,

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
