GearDownFS - Virtual Flight Sim Training and Education since 2009
GearDownFS is focused at bringing high quality, interesting, entertaining, and educational content to the average flight simulator user.
Underneath the flashy graphics and interesting angles of MSFS is a simulator with the potential to teach you a lot about real world aviation. We're here to guide you along your search for information through use of quality video content on our RU-vid channel, and even more support and tutorials on our newly overhauled website (link above).
With a real world pilot-in-training, and two other long time flight simulator users, our interest and passion for aviation has motivated us to share our knowledge, accumulated from many hundreds of hours of FS flight time, with other simulaters. While we can't always gurantee 100% real-world precision in our content, we can gurantee a very accurate representation through simulation.

You forgot the most important force in how an airplane flies. Replace lift with money, then it will show the actual truth on what makes an airplane fly.
Im in love with the sky, and had dreamed of being on an airplane and becoming a pilot. Obviously to become a pilot, I’d have to study the basics and controls of the plane and how it works. This video helped me understand aerodynamics more. I’m 15 and I’m hoping that the things I learn about aviation at this age will help pay off.
The Mystery of Airfoil has been solved ! The reason it took so long to get to the reality of lift was the basic error in assuming there’s some kind of flow of air over the airfoil, which gave rise to various erroneous non-existent and irrelevant concepts e.g. Bernoulli, Flow-Separation,etc. Everything is covered in the book, in detail. The matter was a very simple one, but the wind tunnel gave the scientists true tunnel vision for the past century. Check tekemon.
When a slightly inclined aerofoil starts from rest, it dumps a starting vortex in the flow. This can actually be visualised. If it stops, it dumps a stopping vortex. If it moves in an intermittent start-stop action, it generates a vortex street which can also be visualised. While the aerofoil is moving, the stopping vortex is tied up with the aerofoil as bound vorticity. This generates lift by the Magnus effect. I can explain the Kutta condition and the Kutta-Joukowski circulation theorem if you like, but Magnus effect is good enough. A hydrofoil moving through liquid sodium generates lift by the same mechanism. The same hydrofoil moving through liquid helium with the same geometry or kinematics does not generate lift, because the helium is a superfluid with no viscosity and therefore no starting vortex. Explanations appealing to Bernoulli, Newton or Coanda are useless at distinguishing between liquid helium and sodium.
