After Ronald asked about pulling back the power on a propjet, I
experimented a bit. On a recent flight at fl220, I pulled the power back to burn 23-25 gph
and maintained in the 160's kias and 230's ktas in my TKS equipped
propjet.
Almost piston efficiency. Watta Plane!!!!

Hi Ronald,
Each propjet has somewhat different performance. Mine with tks
deicing
generally flies between 275-300 ktas in the flight levels. fuel burn
is
29-39 gph depending on altitude and power settings.
as a baseline I just flew from key west nonstop to huntington, wv at
fl210 due to strong headwinds and power pulled back some to conserve
fuel and range. I burned 29gph with a true of around 275 ktas in 3;42
nonstop burning through my wing fuel (112 gallons) but still having 34
gallons in the belly tank when i landed. I've done this same flight
previously in 3:10 but the winds sucked on Sunday. I have found that
the turbine engines just burn fuel and 25 gph may be a little low to
maintain any speed though I do get that low on descents. They burn
close to that at idle.
I'd be happy to discuss the good and bad of turbines and the
conversion
options/shops with you if you'd like as I have had both good and bad
experiences.

Hello guys
Today I flew in a Bonanza with an Allison 250 Turbine, and it was
awesome. I was very impressed by performance and the silence and no
vibration.
So I got curious now about having a Walter Conversion done, but when I
was looking for performance data (cruise/fuel flow/ economic or power
@
altitudes) I could not find anything on the web?!
For example I like flying @ 17500ft, just because I can listen to the
radio and do not have to chatter and can avoid bumps when I see one
lol
So what does a walter engine burn at this altitude? Could it fly with
just 25gph and what would be its performance?
Things like that...
So does anyone have this ? And is there anyone I could fly with (I
pay
for fuel) who can show me this in his 4p? (I live in Central Florida,
but I have a 4p ;)
Thanks -- Ronald
