Hi, I’m getting a fuel flow of 57 GPH at 18,000 ft, 146 KIAS, full throttle and nearly full RPM and high idle. I think it’s too much, specially for career missions that can take you a bit far from the starting airport.
Is there a way to optimize this fuel flow? 57 GPH is a realistic qty?
I can’t find a Draco X POH, but the Pilatus PC-12 has a 1200 SHP turboprop motor, so maybe we can use the information from that POH to help us out.
If anyone has access to one or finds one in the wild, I’m sure we would all appreciate some info from the actual POH.
57 gph is about 340 lbs/hr fuel flow. That is lower than the PC-12 so probably pretty accurate going full throttle.
Here are a couple of pages showing anticipated long distance cruise specs for the PC-12. Maybe aim for those numbers at the given altitude and see how you fare.
I’ve found no documentation for the Draco neither. The PC-12 is a bit far from it but maybe it’s useful… Anyway I’ll save some money and I’ll buy one as soon as I can.
If those figures are realistic, then the worst thing of this plane is its range. But it is very funny to fly.
I found out the Draco X has a Pratt & Whitney PT6A-140 model engine.
The PC-12 has a PT6E-67XP.
The C208 has a PT6A-114A.
So maybe the cruise guide from the C208 POH will be a better fit. I’ll have time later this evening to post some pics of that, if no one else does in the meantime.
