Dihedral and Lateral Stability

[dmdas]

As usual, Rod's clear, simple, uncomplicated explanations. Do make more of these short 5-minute gems. Thanks, Rod.

As ever..Rod the best !!! Thanks again..

[Chris-isz]

I'm so glad to see that Rod is still making content!

This is the best visual explanation I’ve watched! Thank you 🙌🏾

Nice video Rod, and I must say... fabulous neckwear!

[louishung]

One of the best and knowledgeable aviation educators. Thanks for the visual explanation, and is there really a group of people think dihedral helps coordinate turn? Never heard of that

[sameeralazawee]

Thank you and i wish you all the best .

[jorgeetrevino]

Thank you Rod.
This is the best explanation about this concept I have ever encounter.
Your explanations are very logical and very easy to understand.
Keep up the good work!

At least you kno how to cover subjects without putting all to sleep! Very important skill set! Thx

[withgrowinginsanity]

yes!!! the real Rod is on video instead of his digital twin 😊

Rod, You are fantastic, very helpful! Thank you. Sincere question... Hypothetically - If a wing had an exaggerated 45° of dihedral per wing, and the fuselage was perfectly balanced as to not create pendulum from the center of lift.... not probable, but lets pretend its a homebuilt expiramental aircraft.... In a co-ordinated 45° bank the high wing would have 0% Vertical component of lift, and the low wing would have 100% Vertical component of lift. Being that wieght is one of the four forces at play, how do these unbalanced lifting forces NOT provide lateral stability? Doesnt the airplane tumble towards gravity, creating inherent stability?

[austinbrace]

Hey Rod great explanation on what I was struggle to understand. This is what the PHAK goes over and as you said only affects stability on a side slip condition. My question on a coordinated bank and wings creating equal lift, isn’t the inner wing producing more vertical lift while outer is producing more horizontal lift or is this negligible and over powered by other effects like a faster outer wing?

[AwestrikeFearofGods]

Another benefit of dihedral is that it inclines the bottom surface of the wing fuel tanks, for more effective sumping of fuel contaminants and water (while parked on level ground). This is probably why high-wing designs bother to include a small degree of dihedral.

[jaypaulbusch]

Is there a course or book of yours you recommend for a training CFI?

[BlaineNay]

Now, explain negative dihedral (eg, C141).
