- (Please Subscribe!) Joe Casey from Casey Aviation joins Dan Millican and Christy Wong for a discussion how in the case of airplanes flying at different air pressures, water might not freeze at 32f or 0c and how the big danger is SLD, or Supercooled Large Droplets.

As a truck driver. I would keep my defrost off. Keeping my cab cold so the snow, and ice would bounce off my windshield. Keeping ice from building up on the wiper blades. It can get cold and it’s time to park.
We need a lot more Joe Casey’s in GA.
This.
Absolutely excellent episode Dan and Christy, thank you. Also thank you to Joe Casey for coming back on the channel to share his incredible wealth of knowledge. I really enjoyed this topic. Joe's explanation helped me understand icing more. Keep up the excellent work as always. Safe skies 🇺🇸🛩️
The 3 pictures over the Joe’s right shoulder are crooked and now I can’t un see it. It’s driving me crazy. 😂
Interesting discussion. Learned a bunch. Thank you.
Thanks for putting the inthehanger logo on the thumbnail. I play them as a podcast and without a logo or you putting them in a playlist, I miss a lot of them.
You bet! And thanks for listening to the playlist. (I do try and be pretty consistent with putting the ITH's in the ITH playlist)
In addition to all the explanation about icing on the wings and the tail feathers, I have also had ice build-up on the plane's wing struts, the front of the engine cowling, and had ice cover the air intake filter on a C-206. The ice on the air intake started starving my engine of air/oxygen and I had to open the alternate air source to keep up the power on the engine, until landing shortly thereafter. Those areas of the airframe should also be considered when a pilot starts accumulating ice.
Joe is one of your very best guests. Excellent content here.
I am not sure how icing works on a plane. But it sure works well on a cake.
Great show! Thank you for addressing this!
Extremely well explained.
Thanks
Certified!!!!!!
Good morning from Minnesota! Great episode!
I think this was an excellent episode as I'm sure many pilots with deicing capable airplanes feel like they are ready for icing and the reality is it's made to get you out of icing conditions.
This video is an excellent explanation on Icing. Not bragging here, but after flying cargo for several thousands of hours in nasty weather over the Rocky Mountains, on a few occasions, I have entered the realm of test pilot. His explanation of super cooled water droplets is dead on. There's a reason as to why they installed a thermometer on the aircraft. And that's to remind you that wherever you might be, water still freezes at 0 degrees C. If your plane is FIKI equipped, the manual will tell what temperature you should activate your anti icing equipment and when you should activate your de-icing equipment. For most air carriers the industry standard is +10 degrees celsius, and to use your pitot heat at all times. Think of your aircraft as a magnet after flying through below freezing temperatures, and those supercooled water droplets looking for something to attach themselves to. After a few accidents the FAA published advisory circulars about flying in icing conditions. I agree with disconnecting the autopilot and flying by hand so you can get a feel as to how the plane is handling, however if the aircraft is FIKI equipped, the aircraft manual has the best procedures as to how to fly that particular aircraft in icing conditions. That is because it was tested in those conditions in order to be certified for FIKI. I can get into this much deeper, but more importantly, the effects of icing on propellers is by far, more important. If there is one book that I would firmly recommend to all pilots, it's called Weather Flying by Robert N Buck. This book has saved my bacon many times, and millions of times for many others. FIKI just gives more time to exit icing conditions in a more relaxed manner. I would be more than happy to explain this better if you would like. Whatever you do, just don't fly around fat, dumb, and happy just because you are FIKI equipped, on many occasions, I have found that this equipment can easily be overwhelmed. Great Video!
This was great! 🙏
A brilliant explanation too, for anybody else struggling, think of a gas/deodorant leaving a can, as the pressure drops it's extremely cold and I've actually seen a fire hydrant punctured before; the entire area around the puncture is covered in ice. This doesn't relate to this video but moisture moved from s high to low pressure gradient is a great way to create some ice?
My first night cross country destination airport had a surprise freezing rain call out when we were 15 minutes out. 180 turn and went home lol not trying to be a test pilot
I did some research on bridge icing since I never had heard of it before watching Joe's presentation. It's not existant in any Australian CASA learning materials. Apparently not part of FAA's either and in 2011 for part 121 the FAA position is you need to use deicing at the first sign of icing now.
I think the easiest way to consider a 'cloud condensing nuclei' is by having one of those gel handwarmers, if you've never owned one, they are a science/chemistry even physicists dream. When you crack that bit of metal and see the supersaturated solution crystalise and give off a big amount of heat energy as the bonds break and rearrange is awesomew. I can imagine something fairly similar happens here?
Check out AC 91-47
varies on altitude. like water boils at lower temp at higher altitude. Water freezes at faster air speeds = air speed = wind chill. altitude decreases air pressure and therefore inscreases air speed over the wing/water. So AS over A/Barometer =ice
Looks like the GoPro at 5:24 got de-iced too. 😅
You run them at highest quality video and they'll cook the ice off. 😜
Good discussion but was surprised that there was nothing about TKS systems.
or as BrYan would say "I can't rely on cirrus chute anymore, so if my toosties feel a bit icy, even after applying 2 extra layers of xmas socks, then it's time for commanche landy. The mighty "Tiny little Gruman" couldn't even handle these circumstances"
I flew a Caravan for 4 years. They have a reputation for not being able to handle ice very well. That is false, the boots do exactly what they were designed to do, which is to buy you time to get out.
exactly. know your aircraft. it's ok to know imc... but like the bend in a road, each vehicle handles things differently. KNOW your equipment. become one with the machine, the rule books and theory can't cover everything. nothing can.
I knew something was off about Christy… science major… makes sense…
Leave yourself an out. Do something at the start of icing.
