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!!!!

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.

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 -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
