TURIN...



What exactly do you mean by 'light hearted'? Is that supposed to mean that you actually didn't mean a word of what you said?



I never asked you to use "high level maths". But...

TURIN....



I have to completely disagree with your stance. Not to be personal but your attitude contributes to the lack of scientific literacy throughout North America and many other places. I...

Fair enough.. I thought it was easy to follow what I was saying but I see what you're saying. In the cases I was talking about, 'increasing AoA' meant that if it was positive, it was getting more...

BOAC... Not being disrespectful, but I honestly don't know why you think I wasn't clear in defining up and down. I could have said something like down is defined as being towards the center of the...

Microburst...

Yes, that A for NA text is fantastic! I would love to study it cover to cover but I sadly don't have the time right now.



I think this would actually be "negative lift" and not...

Microburst... there is a lot more that contributes to airplane stability than just AC (aerodynamic center) and CG! Here is a tiny excerpt from 'Aerodynamics for Naval Aviators' that talks a little...

It sure does! Thanks, I made the correction.



It also improves stability. An airplane disturbed and put into a dive will pick up speed. As it picks up speed (if the tailplane is producing...

I'd have to agree with the A330 quote - the tail would be producing less downforce. The tail downforce acts the same way as weight does - down and needs to be compensated for by lift. So increasing...

I agree, but your basla models weren't carrying lots of cargo at varying CG positions! But I couldn't help but think it'd be hard to be sure that your tailplane was actually creating positive lift...

Not surprised. But I would also be surprised if an airplane like the F-22 didn't produce upwards lift on its tail. Generally, the more maneuverable an airplane, the more unstable. And if I ever did...

I don't have any data to back this up but my understanding is that to provide positive static and/or dynamic stability, most aircraft incorporate a design that has a tail downforce. I think generally...
