well written commentary…

some updates from Wichita here:

These 2 planes are the equivalent of 2 men each building their own "tallest building in the world" at the same time. You don't know what either plane will be until delivery. Neither side will show it's hand because it will be too easy for the opposing side to adapt.

I think there's big news to come in the space.

I hate to always be the wet blanket, but it makes me a little nervous seeing that the whole fuselage side is one continuous skin. If these things have a cargo door, and I assume they will, then it won't take long for one of them to have the skin next to the door stabbed with a forklift.

PC12 has been this way for 23 years

will be interesting to see how that new GE engine will perform and establish itself in the market….

It will be nice to see what Pratt will offer to compete with GE.
Competition is always good.
Im sure Pilatus and Daher are on Pratt for more power and Fadec.

Will there be a twin Denali? A new twin turboprop. GE engines, Garmin panel, a clean sheet design.

What would be the point?

Probably not but I can see a reengineered KingAir with this new engine, should be a no brainer more power lower fuel burn, will fly higher faster and farther on the same fuel load.

I've heard rumors of the possibility that there may be a Twin Denali in the works to replace the King Air 90 and possibly 200 at some point. Probably depends on how the Denali is received.

Texas turbines already bought a PC12 and will be installing a tpe-14 engine on it. Current specs are 300knts and 10-20% less fuel. May become a standard option on the new PC12's.

doubt it…

with all due respect to Honeywell…the 331 WAS a very decent engine….

but it is, let's face it, a bit out of date by now…..design inherent…..

Texas Turbines may well do great upgrades…and they are good people…

flew one of their 900HP Caravans…wild animal…not bad at all…..(but a bit hard to "fix in the field" should something not be perfect…in contrast to a PT6 design…)

but Honeywell has in reality dropped out of this field, long time ago…they are selling off some warehouses of motors now…

but they have nothing new and exciting in the pipeline for new designs…in that class..( correct me, I may be wrong..)

that is the way things go in our industry….you wait too long you are out…

only the early bird gets the worm…..

What would the TPE-14 put out for HP at FL270/280?

It might be fine on a Caravan on floats but I doubt that it put out more than a -67P at altitude.

Produced by Cessna a Twin Denali could have a Garmin Panel
Dual GPS's, (Fusion is one, isn't it? Anybody know for certain?)
Fadec
Good pressurization.
Efficiency, maybe even faster.
Get away from spar problems, wing bolts and sector gears.
Simple fuel system.
Fully integrated systems, even the CAS messages.
Nice useful load without paying extra.
Nice cup holders!!!
Those exciting GE engines.

Anybody else, what would you hope to see in a clean sheet twin turboprop design?

According to the guys at Texas Turbine, Honeywell is losing all their large turboprop engine sales they once had to the airlines so Honeywell is retooling their engine programs to focus on general aviation again. There are a lot of Honeywell components in the 12 (and the 24 it appears) so maybe Pilatus would leverage that relationship more and we will see more Honeywell parts (engine)?

I am predicting that Pilatus will respond to the Denali with a more powerful, more efficient, possibly FADEC PT6 engine upgrade.
