Granted.

Can anyone think of a weather phenomenon that would explain the above? I can't. Sudden downdraft: airspeed remains about the same, VS goes negative, but pitch would not change significantly. Sudden updraft: the opposite - airspeed remains about the same, VS goes positive, pitch stays about the same...

On thing that may have happened, if they were in IMC and in manual flight, is the known somatogravic illusion of pitching up when in fact you are accelerating, which can be counteracted with a strong push down by the pilot. This happened many times in GA airplanes taking off in conditions of very l...

From the avherald summary of the preliminary report today, it kinda sounds like they shut down the wrong engine :cry: It sounded to me that they could not feather the failed engine and hence they didn't have performance to maintain level flight and were forced to descend. That would be sufficient, ...

But apart from that did you enjoy Disneyland?

Ha, I wish.

I don't think Lion Air is simply a matter that the dudes were too stupid to pull up. What I do think is that pulling up should buy them SOME time... more than enough time to say, "oh crap, let me get some nose-up trim going … There is so much wrong stuff circulating... Examine the FDR traces f...

Unlike cars, where you have a huge separation of the flow in the rear, in airplanes you have very little if any flow separation in the fuselage. Under this circumstances, most of the drag is not pressure drag but viscous drag (plain friction), and the frontal area is not a huge factor at all, on th...

What do you make of this panel?

I might suggest "tree", but there apparently aren't any anywhere near the crash site...

I don't see that the suicide theory was ever credible. I'm putting my pennies on severe windshear.

2. Yikes- “Controls free, but can’t tell that they are not_correct.”

Indeed.

The point of things like CRM is to systematize for everyone what top-notch folks do instinctively. Or at least, a large part of the point.

So recently I've had the opportunity, if one can call it that, to drive (for several days) a late-model car with the latest in autopilots and cockpit automation. It is fairly rubbish. I'm not saying whose version, because I expect they're all much the same and I don't see any point in calling out ma...

So many variables are involved in changing from long and narrow to short and fat that that I don't even know what you have in mind when you say "all else being equal". The effects I had in mind were (a) the dependence of drag on frontal area, and (b) short fat objects have relatively poor...

Curious feature that's come out today: very little fuel with the wreckage. Strange, because fuel exhaustion alone shouldn't cause this kind of event. Maybe an uncontained engine failure ripped open the tank and it all vented a few thousand feet up? But you'd need to be phenomenally unlucky for it to...

I have often eyed the dedicated roadways that some public transport can use to get from point to point. I've seen them in Canada and Southern California, I am sure there's one in the OC.

Oh and: Ottawa has a tonne of these.

I'm trying to understand this one. You have a bus stop designed to kill passengers in double deck buses?

Whole series of them.

American units are not the same as Imperial units; quite a few of the latter are different; gallons for example.

According to something I saw the other day in Chinese internet slang "748" means roughly "go to hell". If that's actually true, Boeing's been selling into quite a headwind...

The other one would be to resurrect the 757. Maybe stretch the fuselage a bit, improve the wings, the systems and the cockpit (an the interior) to make it part of the 787 / 777-X "family". And of course put new engines that are 20% more fuel efficient than those in the original 757, and e...

So, a ripped fuselage... guess that means a six-pack ABS. Didn't think E190s had body gear that size though.

unrelatedly, it has also come to my attention that N919FR has an ocelot painted on the tail.

***there are things computers are useful for*** What do you think about them tracking speed and location on a runway and perhaps an inertial acceleration for double-check purposes and checking to see if the takeoffs appear to be on-track? As it so happens, I already have an answer for that: https:/...

I thought about this for a while before shooting off my mouth further (nearly a month!) but now I'll do so: The certification issues seem like a red herring, inasmuch as either some of those aircraft shouldn't be certified, or there should be two certification categories ("pretend light twins&q...
