Boeing needs to start offering a "heated wing" option like automakers do with seats and steering wheels in cars

u/Rinas-the-name 1d ago
I don’t understand why anyone would ever pay for any of that. They wouldn’t do it if it didn’t work on enough people. My much more affordable car has zero subscription features. I wouldn’t but a car that did, and if there was no option I’d sail the high seas in a heartbeat.

Pretty sure they do. I've been on a few flights where we were delayed 30 mins or so for de-icing. Nobody came by to remove ice. It was waiting for the internal heating elements to remove it.

u/ippleing 1d ago
You may have been parked inside of an infrared tent that heats the surfaces.
Large airliners have no on-board de-ice capabilities.

It was an American Airlines CRJ900 and wasn't cold enough for a major de-icing with fluid so my guess is they used the wing anti-ice system and sat there waiting for it to do it's thing. There was no tent that I was aware of. We were still parked while it was being done. Sat for 20 mins or so. Maybe 30.

u/Tony_Three_Pies 1d ago
Nah, no currently operating airliner uses thermal-electric heating for the top of wings.
1
u/Paul_The_Builder 15h ago
Yes, all airliners have anti-ice systems.
There are a variety of types, but the most common type has little tubes inside the wing that takes hot exhaust gas from the engines and runs it through the tubes to heat up the areas that are prone to getting ice buildup.
The reason they still need de-icing on the ground, is that the anti-ice systems are designed to heat areas one the leading edges of the wing and plane and control surfaces - where ice would buildup during flight. They can't heat up the entire plane to get rid of snow build-up like what is shown here. So the de-icing gets rid of the snow buildup from when the plane was on the ground, and the de-icing system can handle any ice buildup that occurs in the air.
Think of it like the defroster on your car - it can handle snow and ice hitting your windshield while driving, but it isn't realistic for it to melt several inches of snow buildup from the car being parked outside overnight, or if it can you might have to run the engine for 30 minutes before leaving which may not be realistic. Scraping the snow and ice off the windshield, and then keeping the defroster on while driving to prevent further buildup is the way to go.

u/JimmyDean82 1d ago
Leading edges are heated during flight. Pulls hot air off specific compressor stages to keep the leading edge hot.
I will say that is at least how it used to be. It could be electrical now. Some prop planes also have a thin membrane on the prop with electrical heating to prevent ice during flight.

u/BlackCat400 1d ago
Still that way on almost everything. I think the 787 is all electric now, but other Boeings use bleed air for anti-ice. I’d assume Air is is similar and most use bleed air.

I feel like airplane windows are a luxury and should be behind a flight paywall. 30mins of windows open time for $15.99.
Yearly open window "Sight Seeing" packages start at the low price of $400 annually. Recurring billing until you cancel.
Also bathrooms are $5.00 for each #1 and $10 per #2. Oversized logs are $.50 for each Oz over the regional standard*

u/AbsolutelyNotAPilot 21h ago edited 21h ago
That’s already is a thing. Problem is it’s really only functional in the air. Hot air from the compression section of the engine slightly bleed off from the engine is used for a lot of things in a plane. Pressurization, air conditioning, and anti icing systems are usually powered by this in large aircraft. When wing anti-icing is turned on that hot air is ducted behind the very leading edge of the wing. This is really only effective in the air because only the very front of the wing is heated. Basically cold moisture hits the front gets hot liquifies if it isn’t already and gets blown backwards by the extreme forces of the wind moving over the wing. So if we tuned that system on while on the ground all the snow and ice would melt but only on the very front part of the wing.
They could design some sort of electrical or pneumatic heating system on the entire wing it’s not the worst idea ever but it would add a ton of weight and make the plane more inefficient. So for right now the best option is spaying the thing with hot glycol to get rid of all frozen contamination prior to takeoff. Or just leaving the pane in a heated hanger overnight. But that’s not a realistic options for airports that handle hundreds of planes.
TLDR: anti icing systems only work on the leading edge of the wing and are only functional in flight. All the other ice needs to get blasted off with hot glycol.

u/DustyMcKnuckles 1d ago
Deicing was one of the coolest jobs Ive had. It was super fulfilling, but the hours are rough and the pay was just okay.
If you live near a larger airport and it interests you, I would definitely recommend giving it a try for a season! September to right about now is when theyre usually still looking for seasonal part timers and anyone who can pass a background check to be let onto the secure parts of an airport can apply.

My question is, would it better to install heating elements underneath the skin and then not do this especially.
2
u/Queasy-Stranger5607 1d ago
No, this is the best method to correct this condition, because the condition does not happen every flight. A permanent system installed on the wing to do this would be wasteful as it would be extra weight which usually would have no benefit to the aircraft operation. Also, there is heating in the wing of this particular aircraft, but it’s not used to melt snow on the ground, it’s used to prevent ice build up in flight.

Guessing propolyne glycol which is significantly less toxic. Some airports have special area built to contain the runoff.

I remember having to do this until the glycol bill came in. The maintenance crew came up with a gadget with a rope I think to remove the thick stuff and we'd just spray the leavings. I think glycol was $5/litre back then (mid 90s).

Is that just hot water?

u/Fab-o-rama 1d ago
No. It's basically a mixture of propylene glycol (an alcohol that lowers the freezing point of water), water, and additives like corrosion inhibitors, surfactants, and color dyes.
Depending on the type, it either melts current ice or acts as a thick shield against new ice

No it’s hot glycol. It’s great at removing ice and helps prevent the formation of more ice

Probably not that long. In a heavy snowstorm you could get buildup like that in an hour or two.

u/CFO-style 20h ago
Most likely overnight snow. The morning flights outbound would have had the planes parked at either gate or remote stand. They don’t clear the snow until deicing anyway, so this it how it can look. Very normal.

That’s a much trickier job than it looks, I would bet. I have watched from the inside too many times. They get pretty close to the body of the plane and have never seen them make a mistake and touch the plane.

It's a heated water and glycol mix most of the time.
Not super warm.
But you want it to stick to the wings for some time so the ice does not come back before it is in the air.2
u/AdWonderful5920 16h ago
There's a chemical. I used to live in Fairbanks and they'd spray the deicer on my flights out. The plane's ventilation would pull in some of the scent and we could smell it when they deiced.
I'd be sitting there like 'ehh this is probably fine. Better than crashing and burning up anyway.'

Had a flight from Syracuse to Las Vegas a few years ago -- in January. The overnight snow had transitioned to freezing rain.
Watched the initial de-icing from the gate lobby. Small airport. Great view. Cool process. A crust of ice formed over the inch of compacted snow on the wings. Flew off in huge sheets. A truck with a giant roller of rubber bristles arrived to sweep away the sloppy slush.
Pilots were going through their pre-trip routine after boarding and pushback. Came on the PA system to inform us that they were requesting additional service and that there would be a brief delay. Would be safe to assume the flaps were not fully flapping.
Not a single complaint was heard among the passengers.
The connecting flight was delayed for a few minutes for several of us to reach the gate. No harm done.
