Aviation Training Tip: Deice and Anti-Ice

0:00After watching this quick tip video, be sure to check out our website at Wi-Fi-CFI.com. Our online aviation courses include Study Courses for the private pilot, instrument rating, commercial pilot, CFI, CFWI, and multi-engine app on Study Courses. All of these include videos, podcasts, quizzes, flashcards, audiobooks, practice FAA exams, check-ride workbooks, and more. We also have courses for just the check-ride lesson plans. These are to teach on those flight instructor check-rides. We've got the CFI, the CFWI, and the MEI add-on lesson plans. They all come in PowerPoint, PDF, and dot formats, word formats. They're downloadable, customizable, printable. They've got animations, diagrams, images, included quizzes, and more. Additionally, we have teaching courses. If you're a flight instructor already and you want to teach your students, you can teach your private pilot, instrument rating, commercial pilot, CFI initial, and CFWI add-on students with flight syllabi, lesson plans, homework assignments,

1:07binders and tracking, quizzes, logbook audits, endorsements, and more. And you can try every single one of our courses for free for as long as you would like at Wi-Fi-CFI.com. Lastly, we're just going to kind of wrap up with some icing stuff. Now, we're going to cover this icing stuff here, but most likely, again, check the limitations section of your POH and your airplane, but most likely, your small training airplane is not approved for flight into known icing conditions. Because icing can be extremely dangerous, and some of these icing systems are heavy, and they're expensive, and they don't put them on light trainer airpods. And so they just say, flight into known icing is prohibited. If you know that there's icing, do not fly into it, that is against the rules. This airplane is not built for it. And even if, even if you do have

2:11anti-icing and de-icing systems on your airplane, and your POH says that you are approved for flight into known icing, that does not mean that you should just blast into icing conditions, and you're going to be just fine. You should still try to avoid icing conditions whenever possible. And if it is impossible, at least you do have anti-icing, de-icing systems, but do not remain in icing, it is still not suggested that you remain in icing conditions for extended periods of time. Try to get out of it. If you've got a climb, if you've got a descend, if you've got a turn, because there are certain situations in flight where icing can build up so rapidly on an airplane, that the systems to prevent it or to get rid of it cannot keep up with the icing formation. Just want to put that out there. So again, we're going to cover these things so that you know how they work, but try to avoid icing whenever you can in flight.

3:15Ising protection. This can help protect the leading edge of the wing and tail, pito and static ports, fuel tank vents, stall warning devices, windshields, and propeller blades. Again, most lighter craft are not certificated for flight into known icing. Some frosty on the wing here. Now obviously that's not a great image and hopefully this airplane really isn't flying because what icing does is it destroys the smooth air flow going over the top of the wing and it's going to destroy your lift. So now your wings aren't creating any lift or as much lift and can't fly. That's what you need wings for. It's great lift. And if this icing is there and you don't have that smooth air flow going over the top of the wing, you don't have lift. That's why it's so dangerous. Deicing boots. These are inflatable boots consisting of a rubber sheet bonded to the leading edge of the airfoil. An engine driven pneumatic pump usually inflates the rubber boots. Again, along the leading edge here, if you start to pick up ice and ice starts

4:19to build up along this leading edge, what you can do if you have these deicing boots is there will be a little switch in the cockpit. You can flip the switch and an engine driven pump will actually inflate these boots a little bit so they'll fill with air a little bit and when they do, it'll crack that ice off and the ice will go away. With the icing boots, you actually, if this is what your airplane has, you actually want icing to build up just a little bit on the front of the wings before you pop the boots. If you do it when there's basically just a trace of icing, then you're going to do the air and it's not going to do anything. It actually needs to build up a little bit so that when you inflate the boots, the ice cracks and falls off. That's how boots work. Pretty self-explanatory, pretty easy. Heated wings, also pretty self-explanatory, pretty easy. We can get hot air from the compressor section of the engine and we can redirect it to the leading edge of the wings and this helps prevent and get rid of ice. More popular on jet engine

5:23type aircraft because these jet engines can get really, really hot and we just bleed off a little bit of that hot engineer redirect it to the leading edge of the wings right here. Keep them nice and toasty. Then we have what's called a weeping wing looks like this. You can see, got the leading edge of the wing. We've got this little metal sheet here across the front of it and this weeping wing will weep. It will leak like an alcohol solution right here, a special solution that will cover the leading edge of the wing and also while you're in flight, this solution will kind of run back along the wing as well and it will kind of coat the wing. Now, why would we want this? Why would we do this? Because this solution that we're using for the weeping wing, it freezes at a much lower temperature than normal. It doesn't freeze until a very, very cold temperature. So, if you can kind of coat your wing, you can coat the leading edge of your wing,

6:27maybe the top of your wing as well. In this fluid, right, which you can weep out, there's a little switch in the cockpit again. You can weep this fluid out. You won't get icing. Well, the idea is, right? I'm not making any guarantees, but the idea is is that you won't get icing until much, much colder temperatures and typically smaller aircraft are not flying in temperatures that are that cold. And so, this can help prevent getting ice on your wing. The one thing about, the other thing about weeping wings is that don't use them as an anti ice, or sorry, as a DI system. They are an anti ice system. If you already have ice on your wings, this weeping wing is probably not going to do a very good job of getting rid of it. All right, it's more of an anti ice. It's okay, we're going to be flying into icing condition soon. Like we can see it ahead, we got a cloud ahead of us from cold temperatures. Let's turn it on now to try to prevent ice

7:30from getting on the wing. Don't fly into the storm or the cloud or the icing condition, start to build up ice and say, oh, let's turn on the weeping wing, because it's probably not going to be that great at getting rid of ice that's already on the wing. It can be okay at preventing it, but not getting rid of it. So, keep that in mind. You got to be ahead of the airplane and thinking ahead. We have a propeller anti ice. So, propellers are protected from icing by the use of alcohol or electrically heated elements. You can have these little alcohol pipes here, these little discharge nozzles that's the word I was looking for. And basically, they can leak again. This alcohol kind of like the same thing as the weeping wing, this alcohol solution, and as the propeller's spinning, it will, it's dripping onto it here. It'll run along the edge of the propeller and help prevent the ice from building up. You could also have electrically heated elements as well. You can have, they kind of look like, they kind of will look a little bit

8:34like boots right here, like the deicing boots on the wings. But instead of inflating with air, what they'll have is they'll just be electrically heated. And they usually will have like an inboard and an outboard section. So, you'd even see it. It kind of look like a boot right here. And then it kind of look like a boot right over here. And they're just electrically heated. So, if you're about to head into icing conditions, you can flip those on and your electrical system can heat those things up and hopefully keep ice off of the problem. Discharge nozzles. Oh, here we go. Heat of boots right here. See that. Right there. I'll give you and get rid of my face so you can see a little bit.
