I feel like the video is updated with a more thorough step by step explanation. After a few months flight hiatus, I came back to review before taking the controls. Your videos helped me pass the check ride earlier this year, and again are helpful to feel more confident towards regaining proficiency. Thanks!
Thank you, CINDY, your explanations are so clear. I recently did my first short field TO, it being a snow-covered runway, luckily there was no crosswind to think about 😃
What I like most about these videos is " No Attitude" it makes it easy to listen.. Too many cowboy pilots trying to use macho guy instead of just being a good instructor.
Good vid. Notes, check out airfield. Look for end of runway obstacles. Flying ground effect, is an associative clause in aerodynamics of flying. & Fears, density altitude, high elevation takeoffs. When to and when not to. Thank you
How much does that change at high altitudes? I live at over 7000’, so if I were to fly and land or takeoff around here it takes more speed to fly out of ground effect. The closest city is 5300’ and we get into the 90s in the mountains and 100+ in the river valley, which makes for high density altitude.
Awesome video. Just one little thing, though, 6:30, ground effect creates more drag, it doesn't disrupt it. I'm a physics nerd and would like to explain to you why, and to be able to picture it easily, let's imagine a calm day. First let's picture a plane that is not in ground effect, as the wings pass through the air, the friction accelerates the air and the tail goes through accelerated air that has a little less drag than if there wasn't a wing accelerating air in front of it (the wing also creates turbulence, which creates drag when striking the tail, but it's a small percentage of the whole vehicle). Now let's picture a plane that is in ground effect. The wings pass through the air, which accelerates a little due to friction then bounces on the ground and is slowed down, then hits the tail at a higher relative speed creating more drag. Ground effect get much more intense the closer you get. In fact, when close enough, the air that was accelerated by the wing might bounce back from the ground and hit the wing, creating even more drag, but also more lift allowing one to fly slower (which is the important part of ground effect). Sorry for the rant. Love your videos.
When landing, I have been taught, and felt, that there is less drag due to less wing tip vortices and other factors. Are you saying during take off the drag characteristics are reversed?
@@genec9560 I do believe, Gene, and I do believe this honestly, is that you are confusing drag with lift. Drag can only be described in a horizontal notion. In contrast, you can only define lift in a vertical direction. When you are in ground effect and the wing tip vortices don't get to develop completely, they create both more lift and drag because they create the opposite of a laminar flow (which is what an airplane is designed to fly in) and instead has a turbulent flow only in the underside of the wings. This turbulent flow creates more pressure, and therefore more LIFT (the important force of flight) I hope this helps visualize what's happening. Much love.
Please cite your sources on how ground effect increases drag. As a CFI I’m very curious on how all academic publications on the subject of aircraft aerodynamics state exactly the opposite of what you are stating regarding induced drag.
You're not taking into account that lift is increased due to ground effect as you stated in your other comment. Therefore a lower AOA is necessary to maintain the same amount of lift and thus induced drag is reduced.

“Don’t forget the winds, they don’t forget you”
beautifully explain by a beautiful instructor, your way of teaching is very good you make difficult stuff easy to understand. thanks Cyndy.
It is really good.
But the volume is very low.
She has to give attention on her speech.
Thank you

Best one for me so far. Always excellent. Thank you.
THANK YOU. LOVE your traing videos.
Everything explained so clearly.👍🇨🇦👍
Again…excellent guidance. 🏴
Thanks Cyndy. Love your videos as always. Love using them for review.
Great presentation. Thank you.
Awesome videos great for review, thanks for posting !
good job captain !

Of course it creates more drag too, but the lift is what keeps the airplane in the air and able to land safely.
