Re: Are [i]we[/i] comfortable with how wings work?

Enough is enough. Time to call the experts.

Re: Aeroflot Superjet at Moscow catches fire after touch down

Tough deal and several independent questions: There are now some answers: -What happened to initiate things? Apparently, a lightning strike. -What caused the bad, bouncy landing (and will Evan determine that the crew used improvisation, and botched clear, easy procedures to land safety)? Still not ...

Re: 737 Over Run, FLA 5/2019

Watched a little of today's NTSB press conference. Apparently they didn't have the full runway to use, as the navy had a wire across the runway about 1200 feet in to catch carrier based aircraft in case they couldn't return to the carrier. They still had 7800ish feet, so should have been plenty. Wo...

Re: FAO: Gabriel; Why don't [i]we[/i] just unplug MCAS?

So I have a stupid question... if the purpose of the thing is to adjust the elevator feel for type commonality, why attach it to the trim and not to, say, the elevator feel system? I do't know. I don't know the design of the artificial feel in the 737. I suspect that it is similar in the MAX as it ...

Re: Are [i]we[/i] comfortable with how wings work?

What that chart doesn't show (but this other one does) is that, while the lift at 45 degrees is comparable to the peak pre-stall lift, the drag is some 100 times higher than that a normal flight regimes, and bigger than the lift itself, giving an L/D ratio (i.e. glide ratio) of less than 1:1, not m...

Re: Certified Carbon Free Sugar

Growing sugarcane and feeding the sugar to humans to make them fatter is in fact a sequestration process for atmospheric carbon dioxide... just not a very efficient one.

Re: Are [i]we[/i] comfortable with how wings work?

And what about kites? They need to produce enough lift to balance not only their own weight but also the down pull force of the string, and many times they don't look at all like airplanes wings. Because they're tied down they don't really have to generate lift at all; just drag and an angle of att...

Hard to understand what happened at the end.

Why did they stop doing what was working? It's...

Re: Atlas 767, Houston

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...

Re: Atlas 767, Houston

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...

That would be sufficient, ...

Re: 757 troubles. the latest news

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...
