The secrets behind De-Icing!

[@DarthMacDaddyM]

I'm an operations lead deicer here at DTW, and let me tell you, deicing in freezing rain poses the biggest complications. During that kind of precip, were no longer spraying to remove contaminants; we are spraying to heat up the metal of the aircraft to a temperature that will break the bond between the surface and the ice that's forming. It's really a race against the clock, and you can dump a huge amount of fluid on a single aircraft. Not only are we racing against the freezing rain, were also working in tandem with all the trucks spraying the other sections of the plane. One truck may be quicker then another, so you have to keep spraying before you're anti icing step can start. All trucks need to be ready to go to that second step at the same time, and the flight crew need to configure for the final fluid application with the quickness. Some points I wanted to add to this video. Not as a pilot, but as a seasoned deicer at a cold weather airport: There are 1 step procedures, which is type 1 only, and a 2 step procedure, which is type 1 and then usually an anti icing fluid like type 4. Depending on the weather, that 2nd step can be type 1 as well; type 1 is heated, and because it warms the metal, it does provide a small hold over time. So a 2 step procedure that uses type 1 for both steps. Theres also a staggered 2 step procedure, which is the predominant method we use. We deice the wings...then have the flight crew configure for anti ice, then we anti ice the wings...then we move to the tail section and switch back to deicing, and finish up with anti icing the tail control surfaces. Staggered deicing is quicker and more efficient then just deicing the whole aircraft first..then driving back around and getting into position for anti ice. Part of training to be a deicer, we learn our roll in the 5 step process. The deicing process consists of the de/anti icing..and then the post application checks. Which can be either a tactile or a visual check. Hard wing aircraft like CRJ200's require a tactile, whereas a 700 does not. Pre take off checks and pre take off contamination checks are performed by the flight crew both before and after their hold over time has expired. This is a point deicers need to know because if a plane comes back for a respray, it may not be because of missed contaminants. Type 1 fluid's chemical properties are what makes it work so well for deicing. It lowers the freezing point of water, causing it to melt. Type 4 fluid on the other hand, has physical properties that make it work the way it does. On a molecular level the polymers that make up type 4 are like long noodles, that settle into a net like structure on the surface of a wing. That net creates a physical barrier over the wing that prevent ice from forming on the wing. Because of how its designed, that net wont move unless acted upon, usually by the rate air travels over it at take off speeds. The fluid will shear off the back taking any contaminants with it. Deicing an aircraft isnt just putting fluid onto the plane. We have to deice a certain way; front to back, leading edge to trailing edge, top to bottom, wing tip to wing root, inboard and out board, as well as symmetrical. Anti icing applications will always start at that particular airlines representative surface. Usually the captains wing tip. This surface represents the oldest fluid on the plane, and pilots will observe that surface throughout their taxi to ensure the fluid hasnt failed. These are just a few points I thought about while watching this video. Great job putting things into perspective from a pilots point of view! You did forget to tell your viewers that you take selfies with the deicers when they are by the nose deicing, but I'll let it slide :)

Marcus Malone thanks for your service, quite ‘unknown’ by too many, but the FOOKER, 100,,,200 HAD WET WINGS, so as they landed, became SPONGES in high RH AREAS, driving was of much importance, as a few welt down after take off due to this problem., NO LONGER MADE. Cheers from NJ

[@bk8541]

whose responsibility is the determination of percentage of liquids (100, 75/25 etc)?

[@yvad541]

@@bk8541 The mix is determined by the freeze point you want to set. The higher amount of water in the mixture the higher the freeze point. In the old truck, I use to deice in, we would have to set the freeze point the day before. The newer trucks can set the freeze point on demand and adjusts to the outside air temperature. So in short the de-icing crew is responsible to make sure the fluid is set to the correct freeze point.

As usual amigo, you hit the nail on the head. Excellent delivery of information concerning De-Icing. This is a big deal and one that is rarely accounted for and incorporated into our departure flight times. Your clear and concise description of the deicing process, especially from the flight deck perspective, will hopefully get shared with the holiday travelers this year. It would be nice if more winter travelers understood the de-icing process, and its effects. Ice build-up on control surfaces is one of the top causes of private plot "GA" general aviation crashes. It is due to a lack of planning, which is so obvious to armchair pilots, yea right. These deadly crashes are the subsequent result of a lot of little errors that set the stage for a big failure. Being able to accurately assess the weather, with all contingencies planned upfront, and not to exceed your standards and personal minimums is the go, no go, talk with yourself. Do not let being behind schedule, overconfidence, and ignorance determine your fate as a passenger or crew. Those who live in colder climates, that frequently get hit with blizzards, freezing rain, and ice, have no excuse to get pissed at anyone other than who is staring back at you in the mirror. The airport professionals will do their best, but for the most part, these 5 conditions or steps of action are not negotiable, especially when life is at stake. A good mantra is: Fail to plan, is a plan to fail.

We were put in queue in toronto for de-icing, which was about 1h30 because litterally every olane leaving needed it, and as we were going to the taciway our pilot said like "every single airport around Quebec City had closed due ti the ice storm and so if Qc closed while we were in the air we wouldn't have any place to land, sucks to be you, good night" and brought us back to wait 15 hours at the airport for the new departure.

[@ad-ir3wk]

Excellent presentation. Thanks 👍🏽

[@AshleyWincer]

When it is possible, I would recommend having the aircraft face into wind after pushback for deicing. When an aircraft faces into the wind during deicing, it is easier to deice the aircraft and can be achieved quicker. Both Type 1 and especially Type 4 is vulnerable to wind..

Hi Petter! Cred to you for all your informative videos. I immediatly thought about Gottröra when I decided to watch this one. Clear ice on the wings was the culprit in that case so I wonder if the procedures of de-icing stems from that crash?

I used to be a ramp agent for Comair, I remember deicing in the freezing cold, getting glycol in my face and mouth. It has a sweet taste by the way. The type II is green like snot and looks kinda cool when you spray it on the wings. I miss those days.

[@Julia-nl3gq]

So we use a gylcol solution here in our apartment building - we put it in the heating system, so the heat pipes don't freeze when it's -40 out. You don't have to have this solution, and it is expensive to put in, but a burst pipe and no heat when it's -45 out are even more expensive, so our landlord had it put in. But... ...but the guy he hired to do it, the guy got a better job offer that day, so he went and did that, and left his 16 year old son in charge of putting the glycol into our heating system (not a straight-forward task, since it involves the boiler, etc., you gotta know what you're doing). Well this kid didn't know. So I was standing in my living room, when this hot sticky mess fell all over me! It was the heating pipe of the apartment above ours. The pipe burst, the water/glycol mix went through the ceiling, and fell onto me. It wasn't winter, it was late summer, cause ya gotta do this procedure in summer, when the boiler is off, etc. Thank god because if it had been winter boiling hot stuff would have fallen all over me. But it wasn't hot. I wasn't burnt. Just very sticky.

Very interesting, thank you. I have two questions: 1) Who desides to close an airport because of weather conditions?

[@Valantir]

1) The airport authority decides based on (Faa, TC, EASA) regulations 2) Airlines have higher weather minima, than private pilots (also known as approach bans) basically we cannot START an approach if the weather is below a predefined limit. Where as a private pilot can give it a try and hope he sees the runway. With that in mind, the captain (at large airlines) doesn't really NEED to decide as the decision has likely been made for him by the company long before his comfort comes into question.

Seriously! Propylene is a plastic made from CORN! This particular formulation and the one used in vaping are used as a binder to keep materials that don't want to be mixed stay mixed. Glycol is actually a word for product made of two different liquid materials. Glycerin and Alcohol. Basically Anti-Freeze! And they don't like to mix period. Propylene keeps them that way. Propylene seems to be from my readings and observations, pretty much indestructible once it's made. It can be recycled MANY times! My airport catches the deice fluids and recycles them into coolant used for air conditioning units in large office buildings and hospitals. By the way. Propylene is also in Mountain Dew and many other soft drinks. It does the same job there that it does in Glycol.

I'm sure a lot of regular car drivers will be ASTONISHED at the meticulous nature of aviation security and decision making. Endless checklists to go through - one for every conceivable situation - all with the express intention of removing the guesswork, hunches and (deadly) overconfidence that accounts for the difference in accident figures between cars journeys and those in commercial aviation. Car drivers have lots to deal with - most notably high-speed traffic within touching distance - so it's remarkable that there aren't MORE accidents than there are. For a commercial pilot, the use of guesswork and discretion is almost a last resort, whereas most car drivers are operating in a very high-risk zone as soon as they leave their garage. I wonder if ALL drivers had to operate with a professional pilot's mind-set, whether accident rates would fall? Would we just see fewer but bigger accidents?

There is northing worse that being stuck in an empty hotel at an airport that has been closed due to the freezing rain. We had to walk over to A to rebook our American tickets which meant we had to cover about 1000 yards of parking lot, no shuttles or trams were working, nobody could stay standing for more than 20 strides before you would drop like a load of bricks. I’ve been in Denver and Salt Lake when 2 inches of snow were falling per hour, while crews kept a single runway open. Likewise torrential rain closed Sky Harbor in Phoenix forcing our aircraft to land in Tucson, but there is nothing nastier that all those 1-3” ice forms you’re risking your life to walk on. I’ve never heard of the condition on either east or west coast, nor the northern section of the Midwest

Congrats Captain. Very good video. Question, how to check if there is ice on the engine blades in an airplane where the engine is very high? Does the airports provide equipment?

[@westsideratmarshall]

You didn’t discuss wing boots and leading edge heat in coming in on landing and decentd

[@martinmatola688]

Vincent Shen Because that's technically anti-icing not de-icing.

Hi Petter. Hypothetical question but do you think given a few hours training you would be able to fly a military jet?

Couple of points to add: No amount of cold (below freezing) Type I fluid will remove contamination from a cold wing. It must be heated. Type I fluid is never applied as a deicing fluid until it is diluted with water. The mixture has a lower freezing point than pure glycol, reduces contamination of the environment by glycol, and saves money for the operator. The amount of water added is adjusted to maintain a safe margin between the current temperature of the air, or of the wing surface if it contains colder fuel, and the freezing point of the mixture. The actual freezing point of the mixture taken from the deicing application nozzle is tested and recorded before each deicing operation, and also after mixed fluids are replenished in the tanks. In cold weather, one unfortunate icing scenario can cause an engine problem while the aircraft is on the ground. After the engines are shut down, snow blowing into the inlet of a still-warm engine can be melted into water that pools in the bottom of the fan or compressor section. As the engine cools further, the water can freeze and physically lock the fan and compressor blades to the engine case. If an engine start is attempted before the ice is removed, the N1 (fan) section of the engine will not rotate when the N2 (or N3) section of the engine is spun up by the starter. If the cockpit crew does not follow procedure and confirm N1 rotation on instruments before adding fuel, the hot combustion gases impinging stationary turbine buckets will immediately overheat and damage them. Time for an engine change. Theoretically, this scenario never happens because, one, engine fans are always physically checked for free rotation as part of the preflight or pre-start walkaround, and, two, no pilot or mechanic will ever add fuel before verifying N1 rotation during engine start. Theory aside, it has happened.

I have one request - please make both of your dogs to sit with you during the videos. Give them airplane stuff toy each to play with. That'd be so cool.
