rocketman Posted November 24, 2011 Report Posted November 24, 2011 From Kelly Aerospace is a new electric De-icing system certified for Columbia and Cirrus. The concept of a heated electric graphite pad that can be bonded to the leading edges of the Mooney wing seems like a simpiler, less corrosive, and less costly alternative than the TKS system. I don't know much about Kelly Aerospace, but if the certification process is not too difficult and the install numbers work out, I would think that there would be enough after market plane owners willing to make the purchase. http://www.kellyaerospace.com/thermalsystems/thermawing_aircraft_deice.html Quote
Jeev Posted November 24, 2011 Report Posted November 24, 2011 Very cool.... Or should I say hot. I'm looking forward to pricing, based on the apparent ease of installation compair to TKS im hoping it's "economical" but it is Avation so my fingers are crossed. Quote

FBCK Posted November 24, 2011 Report Posted November 24, 2011 I believe the other issue was that as the ice melted it ran down to the flaps and alirons and then formed ice there to render them useless and I think that was the killer. Quote
ChrisH Posted November 24, 2011 Report Posted November 24, 2011 ThermaWing may not work (think it melted some wings too due to direct sunlight heating the element). But, this works http://www.coxandco.com/aerospace/lowpower_ice_protection.html Don't think they play in our space though...but great idea. Quote
M016576 Posted November 25, 2011 Report Posted November 25, 2011 Do any of the detractors have proof that this system doesn't work? The system sounds good to me. As for the 'melting/refreezing on flaps' theory, I would find that hard believe. If ice isn't accumulating there already (due to airflow, etc), I doubt it would start accumulating there because the leading edges are heated on a de-icing cycle. Sounds a little speculative. If you have proof, though, I'd love to see it. I'm sure the FAA would to, so they could revoke the STC. Quote
Cruiser Posted November 25, 2011 Report Posted November 25, 2011 This is not a new system. Kelley Aerospace received FAA/STC approval in 2006 for the Columbia aircraft. When Cessna bought them they did not offer this as an option from the factory. Kelley Aerospace will install the system as an aftermarket addon. Since it has been developed on a composite (non conductive) wing, putting it on a metal electrically conductive wing would involve an whole new level of complexity. Since Kelley Aerospace is pursuing the Cirrus now this would seem to be the case. In other words............. don't hold your breath waiting for it on a Mooney, anytime, ever. Quote
AndyFromCB Posted November 25, 2011 Report Posted November 25, 2011 The ultimate system, essentially cabable of handing any ice you can throw at it (it already exists, it's called TKS) would be a combination of this and TKS. Heat the panels rapidly to shed the ice and then let the fluid run back. Dream on, I know ;-) That's the only drawback to TKS as far as I can tell in my limited experience last 2 weeks, must turn it on before getting into ice. I shot 3 approaches in freezing drizzle early in the morning last week and I LOVE my TKS, really the only reason why I bought my Bravo (well, maybe not). No ice anywhere on the airframe on lading other than about an half and inch (after 30 minutes of flight) of it on the wing tips, landing lights and a few small areas on the tail and tips of two antennas. What's the story about the manual stating "windshield de-ice not to be used for take off or landing"? Didn't seem to cause any issues and I sure needed it on landing, well, more like last shot about a mile out. Andy P.S. I presprayed the whole airframe using a Wagner paint sprayer before take off, works like a charm for $65 bucks from Home Depot. Quote
Jasper180 Posted November 28, 2011 Report Posted November 28, 2011 Currently looking for a J or K with TKS, if you know of one PM me (already looked at one PAMooney has advertised) Thanks Erik Quote

Jasper180 Posted November 28, 2011 Report Posted November 28, 2011 Brother graduated from Clarkson and lives in LKP, fly a Dakota up there often. The J with TKS in PA goes up to SLK and LKP often. Will look you up when I head that way. Talk Soon Erik Quote

Lots of family in Long Lake, NY and Burlington, VT. Thought about going to Clarkson before deciding to go to Purdue! ~Adam Quote
