Lift Equation Explained | Coefficient of Lift | Angle of Attack

Your airplane stays in the air when lift counteracts weight. But what factors cause lift to increase or decrease? The lift equation looks intimidating, but its just a way of showing how angle of attack, airspeed, and other factors combine to produce the lift we need to stay aloft.

I’m student pilot in Iran, I wanna say thank you 🙏 for your training, all your information is simple and correct . I use all this information in flight every day and it’s very useful for me . Thanks a lot 👍🏻

The best word to describe professor Dan’s teaching method: exceptional!

[IanHorsford]

Bro you are truly a master at teaching. Seem less understanding of the material…..great job

[doobchec]

Thank you for breaking this equation down. Been flying for a long time and never heard a clear description until now. Appreciate your channel a lot!

BTW Hope you received clearance through the DC SFRA in your sim video 😉.

[stormbytes]

Outstanding presentation! Everything is so clear now. Thank you!

[mikes]

Well done. One tiny little nitpick, the variable 'v' is not velocity. Velocity is a vector variable (speed and direction), which is symbolized with a 'v→'. The variable 'v' is actually speed. It's a common misconception but speed and velocity are different (speed is purely magnitude, while velocity is magnitude and direction).

Thank you so much for this video! I had issues understanding this formula since yesterday, thanks to watching several videos, asking a few questions to my pilot bf + this video, I now understand the formula. Thanks again

[Faris_baasher]

Well done as usual, but i would loved if you’d go a little bit in depth explaining the Reynold’s number as you went through the Cl
I know its not on the syllabus but it’s was still fun to understand it relationship with the AoA and so on
Keep up the good work

[platinum]

This professor would easily simplify “rocket science “ (break it down and put it back together).

Thanks

PS: I do feel guilty not paying for this. I’ll figure it out

[anzebicek]

literally had this lesson today in ground school

[cobra]

another excellent video. Do you have one in the works exploring the relationship between CoG and stability/performance? That's always been a hard one for me to understand well.

[benjaminjohnson]

For simplicity sake this is grade! The only thing that would make it better but also more complex and longer would be going deepering in to bernoullis equation for pressure, and some even debate that the quanda effect plays a big part in lift generation. Basically one could easily make a 10 to 20 min video on just the Cl because of this.

[marijnjc]

if you turn on developer mode in MSFS I think you can visualize the drag, lift, propwash etc

[Zalaniar]

I noticed you spoke a lot about deflecting air downward to produce lift during this lesson. What about Bernoulli's Principle, and the reduced pressure over the wing causing lift? Is that factored into this lift equation as well, or is that a separate equation?

[jerm]

It’s Bernoulli's principle. Differential of air pressure, not pushing air down.

Hey it is great content thanks for sharing but i'm confused about if we climb then we increase our aoa and it causes drag to increase also. So, we increase thrust too for compensating it. So, to the lift equation, when we climb, we increase the lift compared to its steady and level position but weight stayed same. So, why do they say lift is smaller and so load factor is when climbing? I know weight seperated of its component but in anyway it stayed same while lift is increased by both aoa and thrust. Anyone to explain?

[Virtualmix]

The pilot can extend the flaps to increase the surface of the wing and therefore increase the lift (and the drag).

[flemmingstelling]

Why is "P" / Rho equal to 1/2 only ?

[vlatkopopovski]

The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force. Low pressure creates force normal to the cord (contact surface), and it name is "aerodynamic force" because is made from the air (aero) in motion (dynamic), or wind relative to the wing (object).
