Re: Air France tailstrike

Ok, there is no more CYKZ, so the nearest airport-grade metar data (at least ten meters up) E of YYZ is Trenton Ontario. Archived GFA 211800-0000Z maps are enough to identify directions of circulation drawn in by trough.

Edit

Re: Air France tailstrike

Ok … drawing an arrow from the middle of l.Ontario towards the nearest lowest pressure you can see on the map .. That means the air from over the east of the lake also heads in that direction .. held warm by the water it moves that way because all around the lake cold air flows downhill onto it (flo...

Re: Air France tailstrike

airbus uses a "Ground Speed Mini" function. https://www.smartcockpit.com/docs/A320-Ground_Speed_Mini_Function.pdf Since this took place after landing the wind does not appear to be a factor in the tailstrike. If the mini function had 8kts tailwind example for 2, instead of the 50kts hdwnd, and “tow...

Re: Air France tailstrike

My first thought is loss of lift due to airspeed(or decrease in wind), the reaction to the sudden drop was pull back while very likely calling for a go around. A “decrease” seems already happens gradually here ( warm air aloft drawing from southeast … toward North ) experienced after right turn tow...

Re: Air France tailstrike

I noticed the ATC question about it, so it just seemed to me they were curious what that was from the pilot’s perspective….even though it might seem so very obvious to an onlooker.

Re: Air France tailstrike

Air France and 24L don’t mix. The O5 accident on this same rwy came through a shot of 30-40 tailwind component not too far from the threshold, with the severe wind shifts around some unusually heavy thunderstorm activity encountered at a time when a number of other flights were diverted to alternat...

Re: Air France tailstrike

I was a passenger on the flight. The flare was quite exaggerated and I knew just before the impact that it wasn't ops normal. But the strike felt more like hard landing rather than a tail impact. The captain made a PA saying they went around because of the runway being occupied. :rolleyes: “Used up...

Re: Jet stream down

The “wet snow flakes” impacting rwy surface “ at -15” C are solid on contact and even a thin coat stiffer snow is affecting ground acceleration / IAS. After “longer” liftoff would be forced to shallow climb in northwest direction when “inversion” air above is from S/SE direction. (Referencing from g...

Re: 152 Crash CEJ4 - August 29th

Speaking of “checking airspeed” … it’s also about navigating from the right seat here; that is another thing that comes to mind when having noticed an airspeed bleed …. it’s about catching it immediately which is enhanced (noticability) by its location top left corner immediately in front of you the...

Re: 152 Crash CEJ4 - August 29th

The lack of (high density alt) leaning factor (1) makes sense as contributor to diminishing of the power curve and by associated plug fouling tendencies that arise with the resulting rich mixtures (excessive). Mixture here found to be at full rich during departure above 5000o DA. … That could be dis...

Sun altitude highest of the day there is 25 degrees above horizon. At the lowest point it is zero at sunrise, which is the same everywhere. One interesting difference here at Niagara Falls, the dawn is half an hour before sunup but up there it was over an hour before .. (Edit: rethinking previous po...

Re: Air Tindi Twin Otter Down

The nose wheel/ski telescoped into the nose and underside of the cockpit and mangled it pretty badly, main gear is flattened, the right engine power section is torn out and dangling, and the wings are bent down and twisted forward. https://i0.wp.com/cabinradio.ca/wp-content/uploads/2024/01/B5D7B724...

Re: MH370 found 10 years ago

If it turns out to be a positive match then Christopher Olver’s “wing from an airliner” would immediately take first place as the earliest find of this tragedy now almost 10 years ago. Easy to check since only 3-400 ft (100 meters) depth with co-ordinates given. With the extra weight of the net shou...

Re: Flight Aware

We hardly ever talk about tires. So it’s too bad you got trouble for talking about tires …

You worked at CYSN a long time … still drive the motorcycle? Interesting that so many great pilots started out with driving motorcycle.

Re: MH370 found 10 years ago

If that was the “jet wing” that floated in from far away it (likely with some entrails) could have got hung up on the upslope toward the underwater volcano (sinking/grounding a few hundred meters there from the “northern lip”). Out of fuel MH370 (a 777) has tank venting at the wing root, and that be...

Re: MH370 found 10 years ago

So with that …then the tip of a large wing (if as IMO would have been the highest point floating along … ie would have looked like a shark fin) could never have been below the surface (likely slowly sinking more over time) if indeed this was from that tragedy. Also, what’s going to be trailing behin...
