Not sure about Dukes, but here are some observed performance data I've compiled from my 56TC (TG-26). Interpolating I think you'd see 209kts at 18,000 & 40 GPH. I bought my 56TC 15 years ago because it's a hot rod, and still own and fly it for that same reason. It's a pleasure to fly and has great flexibility. You can go slow and sip fuel if you want, or you can haul the mail. I love it when ATC says "King Air 79X descend and maintain..." or "N79X say again aircraft type?" I wouldn't trade it for a nice Duke or 58P, but that's just me. They're not for everybody, but if you're like me there's no substitute.


Bad ass. What my B55 wants to be when it grows up. :thumbup:

Altitude MAP RPM TAS GPH

not so sure about the sipping fuel part. If you slow down a B55 it will have basically the same economy as my travel air at 8K ft: 160-165 kts on ~18gph

why is the 56 nearly double the fuel flow at that speed? Is it that much heavier ? Or are the monster engines and props just not that efficient at low power?

At idle on the ground each engine shows 5 GPH

Because the "Duke" engine is a pig and won't run Lean of Peak.

The TIO-541 Lyc is a great engine with terrific power and smoothness to match the not inconsiderable fuel consumption. You can throttle back and enjoy the ride with fewer GPH going through your wallet though - so there is flexibility - just pick your poison!

That's as much as Jeff's Champ uses on takeoff. :D

Just to keep it in perspective, that's light off fuel flow for a comparable turboprop- but the rest of the start and idling uses even more.

Turning fuel into noise is a noble thing! :pilot:

Why buy a duke when you could have a 56TC. The TIO-541's are the smoothest piston engine I ave ever been behind. Sooooooo smooth.
