okent Posted February 22, 2020 Report Share Posted February 22, 2020 Took my 1st long cross country with my wife in the CTLS this weekend. Flew from Tulsa to Nashville. Weather was good both ways just they had a headwind on the way back today. Interesting there was no covered parking or hangar space at Nashville so it was parked outside on the tarmac and was snowed on one day. Never got warm enough to make it all go away so when I got up to take off this morning it was covered with a light frost/snow. Had to go and get the ice like the big boys. Pretty interesting. I know there's got to be a pic out there somewhere of 230C lined up behind 3 commercial jets getting deiced! Quote Link to comment Share on other sites More sharing options...
AGLyme Posted February 23, 2020 Report Share Posted February 23, 2020 Excellent... if you can make Nashville -- certainly you make it to Sun n Fun...; ) Good post. Quote Link to comment Share on other sites More sharing options...
okent Posted February 23, 2020 Author Report Share Posted February 23, 2020 . Flew to Oshkosh last year in the CT too. Planning on a back country flying course at Stick & Rudder mid July and then Oshkosh again this year so my wife would kill me if I went to Sun & Fun too.

okent Posted February 24, 2020 Author Report Share Posted February 24, 2020 My buddy and I bought a Kitfox S7. It's about half done so we thought it was time to get the tail wheel endorsement and kitfox signoff. Quote Link to comment Share on other sites More sharing options...

Every CT owner should make that trip, I did it and enjoyed it immensely. It's a fun arrival procedure and landing there is great. Just don't screw up, because all of aviation is watching!

Andy A Posted February 25, 2020 Report Share Posted February 25, 2020 How much does it cost to get a CT deiced? I've heard horror stories about it costing thousands of dollars for light twins. Quote Link to comment Share on other sites More sharing options...
okent Posted February 25, 2020 Author Report Share Posted February 25, 2020 It took 10 gallons and they charged me $220. I can't really complain as there was no way I should have taken off with the amount of ice/frost on the plane. The lady at Atlantic FBO said that some private jets cost 2K so I had a ball park. Seemed really reasonable. My total cost for the trip was less than two first class tickets from Tulsa and back. Edited to add that they told me the total gallons used and time required. I guess it's a combination of the two as to what they charge. The fluid was also heated/warm. The private jet in front of me took over twice as much fluid and 3 times longer.

AGLyme Posted February 25, 2020 Report Share Posted February 25, 2020 Kudos for doing it. I know people who wouldn't have taken the de-ice option and perhaps added another 5 knots to the takeoff roll...; (... sounds like a great trip. Well done.

John Vance Posted February 26, 2020 Report Share Posted February 26, 2020 Are there any concerns about use of deicing fluids on composite aircraft? Quote Link to comment Share on other sites More sharing options...

John Vance Posted February 26, 2020 Report Share Posted February 26, 2020 It looks like there are four different types, and at least two of them (I and IV) are for metal aircraft only. Not sure why that is. I couldn’t find much on II and III. Probably not a big deal for one application, but given FD’s direction on cleaning fluids, I’m kind of particular about what I allow on my airplane.

okent Posted February 26, 2020 Author Report Share Posted February 26, 2020 I had requested a heated hangar but nothing was available. (found out the morning I departed) The fluid was listed as glycol, so maybe ethylene glycol. I wondered if there was any risk to the aircraft but I had read where guys are carrying antifreeze and pouring it on their wings for frost.

John Vance Posted February 26, 2020 Report Share Posted February 26, 2020 I found this at https://aircrafticing.grc.nasa.gov/2_3_3_1.html The website has a discussion of the four types and their applications. I haven’t found anything that says they’re not OK on composites, however the msds sheet for type I indicates that it’s on the alkaline side, is an eye irritant, etc. Just food for thought.

Even though they are composite there is a difference in composite construction processes. The CT uses a foam core that is susceptible to degradation when expose to high Ph levels. There are CT's running around with wrinkled skins due to the foam material dissolving between the two layers of carbon fiber. Quote Link to comment Share on other sites More sharing options...
okent Posted February 26, 2020 Author Report Share Posted February 26, 2020 Thanks John, the type used on mine was orange. Interesting that there is a minimum rotation speed. It seemed almost like a super thin gel. Tom, with the alkaline PH is that an issue? Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted February 26, 2020 Report Share Posted February 26, 2020 1 hour ago, okent said: Tom, with the alkaline PH is that an issue? Yes. check out care and cleaning in you AOI. It should be section 8, page 3. Quote Link to comment Share on other sites More sharing options...
okent Posted February 27, 2020 Author Report Share Posted February 27, 2020 I knew that alkaline can be an issue but just didn't know what the magic PH number is for our planes. My google-fu isn't great but from what I can find the de-ice fluid is tested and should be have a PH of between 6 and 10. So slightly acidic to basic.

If you click on the MSDS that I posted, you can view the whole thing, and it shows the Ph on page 4. Quote Link to comment Share on other sites More sharing options...
John Vance Posted February 27, 2020 Report Share Posted February 27, 2020 Also be aware that the Ph scale is logarithmic, so a difference of 1 actually means 10X. Quote Link to comment Share on other sites More sharing options...
Andy A Posted February 27, 2020 Report Share Posted February 27, 2020 I wonder how the composite materials used on the CTs compares to Cirrus? A lot of Cirrus' planes have TKS systems. Apparently they don't see an issue with it. Quote Link to comment Share on other sites More sharing options...
okent Posted February 27, 2020 Author Report Share Posted February 27, 2020 Sorry John, I missed that. The link is dead on the MSDS but I just looked it up. PH is 7-9. Quote Link to comment Share on other sites More sharing options...

I couldn’t find anything on the internet to indicate that it’s a problem, but FD publications steer us away from other than Ph neutral products on the CT.
