Yeti Airlines Crash

Ch 7 reporting an Australian was onboard.

The attitude got out of control very quickly.

Without offering any comments on why this happened, that sort of roll is not usual at the point pilots describe as a "departure", i.e. departure from controlled flight. Wing drops are generally very rapid, and you'll need a lot of height to recover.
 
Husband and son flew on this flight a few years ago. He has a rather terrifying video of that flight but It seems that is par for the course on this journey.

I suspect/hope that will turn out to be fake.

Avherald is reporting it’s one of two videos that have been falsified which is good because the live streaming video is a fairly good effort (albeit a sick and ghoulish) one.

ABC seem to indicate that the video was legit so who knows 🤷‍♀️

“In footage taken by a passenger out of a window as the plane came in for a landing, buildings, roads and greenery are visible below.

The video, by Sonu Jaiswal and verified by The Associated Press, then shows a violent jolt and a series of jerky images accompanied by yelling before flames fill the screen.”

I think that must mean “officially opened”. Seat Son and GF definitely flew on Yeti airlines in and out of Pokhara new airport in May 2022 to do Annapurna base camp.

Allegedly its not a new airport but a second runway was recently opened for international traffic. The original single runway to be used by this flight is now designated the domestic runway.

Here's the fact check of the footage: Is this Real Footage From Inside Plane Just Before it Crashed in Nepal?

It's been verified by a variety of independent, reputable sources. BBC, Guardian etc. Friends of the deceased have also confirmed the authenticity of the footage.

Some commentators saying thin air due to altitude in Nepal contributing to risk of Stall. However the airport PKR is lower than Cooma airport OOM (AMSL)

Basically, IAS is IAS. The altitude will mean the TAS is a little faster than that IAS would give at sea level, and the most noticeable effect of that is that you'll have more inertia than you would for a given IAS. But, as aircraft fly on IAS, and that is what is displayed to the pilots, it's not really an issue. The elevation of Pokhara is quite trivial, at 800m, (so only a few hundred feet higher than Canberra).

They were going to the new airport. Just look at the FR24 tracks for that aircraft for previous days. The accident, whilst more or less over the old airport, is also about the position for a visual left turn from base to finals for runway 12 at the new airport. It's also about 2.5 miles from that runway, which would give an altitude 750' at that position. It's always hard to pick altitude from video, and they do appear somewhat lower, but not dramatically so.

I've had a really good look at the video (and the slightly extended one). I hate to say it, but I think it's real. Simon on AV has made his statement about it being false, based on a simple claim that the first part is from an earlier flight. Given that it seems people who would know have verified the identity of the people in the images, unless they'd been there multiple times, that seems unlikely. And a simple comparison of the view out the window, with Google maps, easily locates them at the correct spot(s) in Pokhara. Simon's second comment is that the pitch up should have been evident, but I don't agree.

Using the video on Youtube from German Aviation, which has the people censored, but is also slightly longer than others.

At:
22 seconds 28.214281852158884, 84.01052514930174
28 seconds 28.2147664103637, 84.00649284947228
32 seconds 28.21556833481977, 84.0036362019142
35 seconds 28.215896736961174, 84.00203551444825
Break in the video
41 seconds 28.206939134137166, 83.9878162919298
47 seconds 28.20506034897683, 83.986320458261
52 seconds 28.2023349191071, 83.9854020384971

These positions are all consistent with a visual circuit to runway 12 at the new airfield. It does overfly (or come very close to) the old airport, but that would be normal given their relative locations.

Looking at the wing, there is flap, but not a great deal. The obvious suspicion would have to be that they've missed a stage of flap. Insufficient flap will most certainly lead to a stall. The wing drop is consistent with that.

I also found that comment to be a poor justification for discrediting the video. At first I thought it was real and now I don’t know, surely if it was from a previous video on a previous date that could be posted?

Should probably point out that Simon isn’t a pilot but a software developer and aviation enthusiast.

Why does the action of aileron input to correct a wing drop due to stall actually exacerbate the stall.
Click to expand...
That’s a pretty simple one.

The ailerons will be deflected up on the wing that you want to move down, and down on the wing you want to move up. The aileron deflected down increases the curvature of the wing (the camber). A wing with more camber will produce more lift, but will stall at a lower angle of attack. As we are already in a situation of too much AoA, the wing with more camber will be pushed even more into its stalled region. This was easy to demonstrate to pilot trainees. You just had to slow until the aircraft was just barely above stalling, and if you input a large amount of aileron, the side with the downwards deflected aileron would stall, and the aircraft would roll in the opposite direction to the aileron input.

Something about the end of the video doesn’t seem quite right? It feels like some of the sounds and/or flames have been added at the end? The first part seems genuine.
