Correction: At 10:15, I say that the left aleron moves up when the control wheel is moved to the right. Of course, it moves down, as the image shows.

[@claudescarpelli8899]

Thank you Magnar (first name edited) for this thorough review on flight into icing conditions. Very interesting. I agree it may have been longer. I’m looking forward to watch more video from you. Best regards, Claude (Cessna 172 IR pilot)

[@claudescarpelli8899]

Sorry, your first name is Magnar. My apologies.

[@bbgun061]

Thank you for this video. It’s good to know that changes have been made based on our new understanding of ice formation. But disheartening that pilots still fail to respond appropriately to keep their aircraft flying. It’s up to us as pilots to do whatever it takes to save our own lives, as well as the lives of our passengers. If that means busting an altitude clearance, so be it!

[@jetnoise6053]

Very well explored and explained - thank you Magnar !!!

[@georgiak6017]

Lovely, calm documentary and incredibly well-explained.

[@Allan_aka_RocKITEman]

At about 28:27 in this video: As a Chief Petty Officer I worked for in the US Coast Guard used to say... *_"There is NEVER enough time to do it right THE FIRST TIME, but there is ALWAYS enough time to do it right THE SECOND TIME."_*

[@NicolaW72]

It lasted only 34 years to implement the appropriate new Rules!☹ Thank you very much for the Debrief of this infamous Crash, usually called the Roselawn Desaster.

[@FlyingInEurope]

Best aviation content in KZbin! Learning a lot from you, thanks!

[@ernestoherreralegorreta137]

Agreed. My thoughts exactly after having just discovered it. Most informative and zero sensationalism.

[@chriskirkland1347]

Good concise explanation of this accident. One of the factors in this accident was a lax atmosphere in the cockpit in recognized icing conditions. A good subject for a future video would be to address complacency amongst crews in automated cockpit environments. Thanks

[@musiqtee]

Good idea. Still, Magnar did mention the importance of flying the aircraft manually if icing gets closer to critical. Also increase speed to or above icing speed bug, and descend for speed and exiting the adverse meteorological conditions, not awaiting ATC clearance. I would guess (!) MCT power selected, maybe also throttles forward of auto, manual use of condition levers to increase prop speed if needed - and vigilant monitoring! Hands-on flying should give PF good mechanical feedback, and maybe the ability to react to this dangerous ctl-surface deflection…? Yes, *guessing* because I’m *not* a pilot… Well made, sourced and explained, capt. Magnar…! 👍

[@cantstandtheestablishment4004]

Yeah, if you read the NTSB report, the crew was not focused on the situation and did not comprehend its seriousness.

[@kalashnikovdabs]

These disaster breakdowns are great keep up the good work captain!

[@Allan_aka_RocKITEman]

FWIW: I just started watching this video. I subbed to _this channel_ AND to _Disaster Breakdown._

[@pilotpat86]

Great work, thanks for sharing!

[@MichaelReutlinger]

Thank you Captain, this was a highly educational video.

[@CatarineausArmory]

Thanks Magnar. I thought that they changed the inflatable ribs from horizontal to vertical when they redesigned the boots for this icing solution.

[@arb6591]

Very interesting. Thank you, Captain!!!

[@sofloemir]

Hey Magnar, Microsoft Flight Simulator just did a big update to the ATR. I enjoy your how to videos with that plane on MFS. Can you check you the updates and give us your thoughts on it?

[@MBkufel]

After watching the last animation in the video I'm puzzled. Why would anyone pull upon shaker activation

[@dermick]

Inadequate training.

[@hazeover100]

I was living in Chicago on that Halloween in 1994. The weather was terrible, very windy with mixed precipitation. I've been on a good amount of 72's over the years and have always thought the wings looked a little narrow/out of proportion for the size of the aircraft.

[@malcolmwhite6588]

@@gottadomor7438 An American Eagle pilot who had been trying to raise the issues that ultimately got discovered about the ATR became what is popularly known now as a whistle blower , the company tried to discredit him they Demoted and I believe ultimately sacked him- a tragic story I don’t know if he commercially flew after that?he wrote a book called “unheeded warning -the inside story of American Eagle 4184”his name is captain Stephen a Frederick I’ve heard him speak he is very articulate

[@hazeover100]

​@@gottadomor7438I actually slipped and hit the deck crossing Clark Street at North Ave later that night so two of the three best Bears players of all time did better than me.

[@AdurianJ]

Linjeflyg Flight 618 had a similar crash where the extension of flaps in icing conditions caused the airflow over the wing to separate. They dived straight down into a parking lot near Bromma Airport.

[@FlywithMagnar]

That was tailplane stall

[@arb6591]

Thanks!

[@Allan_aka_RocKITEman]

At 37:38 in this video: Does anyone know what the story was behind this Lockheed C-130 being iced up? {The same image is also shown earlier in this video.} As best as I can remember, Lockheed C-130s have some form of radome anti-icing and/or de-icing. I was wondering if the icing system on this particular aircraft failed?

[@alexanderarteaga7630]

First thumbs up😊

[@user-bt6we8qp1h]

UT 120, Tumen, 2012...

[@TheNapalmFTW]

The crash site is 20 minutes from my house. I've visited it. Very sobering.

[@n310ea]

Does the Lockheed C-130 have the same icing problem as other turboprops?

[@kcnairnair7299]

Does FAA stand for F***All Always?

[@TRPGpilot]

No. Its an abreviation of Federal Aviation Administration which is a federal agency and is based in the United Staes of America which is equivalent to the Civil Aviation Authority of the United Kingdom where i'm currently based.

[@MeaHeaR]

At 10:15 he is Wholly INCORRECT, , the way aircraft are designe only Allows ONÉ aileron to be move up whist t'other movéd down. This is what be provide roll. the aileron CANNOT both be move upp or down att Samé timés 😟😟😰😩😩😰😟

[@FlywithMagnar]

My bad. Thank you for correcting me.

[@iliag1]

The anti-freezing wing boots was to thin After the accident they were increased segnifantly Still just bcs of this accident no northern country use them LoL

[@Rookie_One]

No true, Inter-canadien continued to use the ATR until their bankruptcy (caused by the collapse of Canadian Airlines), and Canadian North, Air North and Calm Air still use the ATR. In Europe DAT still use them too

[@NicolaW72]

@@Rookie_One And NORRA, a subsidiary of Finnair, Logan Air in Scotland and Bra in Sweden, too. There´re probably more Dash-Operators in the Northern Countries than ATR-Operators but ATR are still commonly in use there. Only in the US the ATR were practically outfleeted alltogether after this Crash.

[@Rookie_One]

@@NicolaW72 Outside of the biggest operators, most smaller operators here in canada use the ATR. That said, Bombardier at the time killed the dash8-300 and only produced the -400, while most smaller operators don't need the -400 and would had bought a newer -300, which mean that most of them switched to the ATR42 if they were not using it already

[@NicolaW72]

@@Rookie_One I´m not aware about the fleet sizes of all the relevant Airlines in Canada, I know only that Jazz Aviation, Porter and Westjet Encore are using the Dash 8 and they´re some sort of the "Big Three" of the Regional Airlines in Canada - at least as much as I know. I looked a little bit more about Nordic European Regional Operators and I recognized that after the bankruptcy of Flybe in the UK only Wideröe in Norway is using Dash 8. Emerald in Ireland and the UK and Xfly in Estonia are using ATR, too. RAF-Avia in Latvia is using ATR and Saab 340 and Airest and Nyxair, both based in Estonia, are still Saab-Operators, Nyxair even with some remaining Saab 2000, allthough this are now very aged aircrafts.

[@Rookie_One]

@@NicolaW72 most smaller operators runs place where the big 3 don't go. Calm air, Canadian north, air north, etc...
