Air Canada aborted takeoff video

[JordanD]

I'm not a MTC guy, but I think that was the thumping. I'll try to get the Mtc Mgr behind me to listen to the video.

Are you trying to get him to kill himself?

hahaha, either that or he will want to strangle the video maker.

Yup, with oxygen in them, they would catch fire.

Sorry but that is not the reason. there is enough other things down there to catch fire, hydraulic lines, tires etc... The tires are filled with nitrogen because nitrogen is a very dry gas. This greatly helps control corrosion problems inside the aluminum or magnesium wheels. I am sure that there are a couple of other reasons but fire prevention is not one of them.

[Mungous]

^ both reasons sound right; Nitrogen is inert (unreactive) therefore doesn't corrode. If the tyres had oxygen in them, they won't catch fire themselves but might intensify any existing fires if they burst.

I trust all your judgments, but is there anything online that explains it in more detail.

A good point I would like to make. Earlier on in his statement, he said that he was an "airline brat" and that he knew "What was going on in the cockpit at any given point". If he knew what was going on, how did he miss the fact that it was a problem with the landing gear....
Hmmm, good job douche...keep plugging away those dollars for flights, you may have more time than a certified pilot, but the pilot of that 763 probably makes more than you ever will in your lifetime......I wonder if he would be willing to sell any of his Star Wars collection, or Battlestar Galactica dolls...

"A passenger saw an Asiana 767...." yea, ok...and I just passed Santa on the freeway....

Tires are filled with nitrogen due to the moisture content of compressed air. If you filled them up with compressed air, you could end up with blocks of ice in the tires. Might make them a little out of balance on landing.

Yes, they guy in the video is an asshat. (good one) Lynching him though? Come on guys, it's way more fun to poke fun of someone that's alive. I'm sorry I missed my chance to flame him on the other site.

[Chris@YYZ]

Well, actually he is. I saw a post of his video on a.net but he was getting abused by the members so he removed the video, fortuently he didn't take it off the net

ROFL!

I was wondering about that, thanks for the explanation as to why they are filled with nitrogen.

Well its one of the reasons why. Oxygen would heat up way to fast on the ground due to friction.

Nobody would ever consider filling the tires with oxygen in the first place. Airplanes with innertubes (most piston powered light aircraft) use plain compressed air the the tires. Airplanes with tubeless tires use nitrogen because of the anti corrosion properties. Nitrogen is not used for fire prevention in tires. What is your source for this belief?

Both Goodyear and Michelin's aviation tire web sites mention the benefits of "dry nitrogen gas" in one place or another. One of which states the gas will "not sustain combustion". That wording is from the Goodyear site.

Hmmmrrrrp.. I wonder what is the proper values for V1, VR and V2 for B767's, values as in how many knots. ?? I presume that one have to count includes MTOW ? Just curious..!

[JordanD]

The speeds are never the same John. It's all dependent on the weight of the aircraft for that particular takeoff. It can probably vary from around 120-160 knots, but I don't know. Where's AJ?

Well, I am not AJ, but I am Phil and I fly 737s... not exactly the same aircraft type as in the video...
I watched all 12 minutes of this video and I was about to switch off my speakers... This guy is so annoying... Jesus...
Anyway... The take off speeds vary a lot! Every take off has different speeds, because of different weight, temperature, air pressure, wind, runway length, terrain, 2nd segment climb limits...
Considering all those facts you get proper speeds for your take off! You can abort the take off until V1, afterwards you have to get airborne... and hopefully land safely again!
The speeds on our 737 vary somewhere between 110 (lowest V1) like on ice runways or snow... and the highest V1 I have ever experienced was 166 in Frankfurt taking off runway 18! This is freaking fast for our small 737! It was basically a standard day and we were fully loaded, maximum take off weight. FLaps 1° take off! V1: 166, Vr 167 and V2 171...

I hope that helped a bit...

Thanks Phil!

We'll be doing a close to max weight takeoff from Sydney bound for Hong Kong today, I'll jot down the figures!
