This explanation fixed my frustration about flying Cessna C127SP Spyhawk in Flight Simulator X. During takeoff, gliding, and landing, the aircraft always bank/turn left. So this is the reason behind that. I tried using 2 engine aircraft )Bombardier aircraft and never experienced that thing again. Thanks much Jakub...
Just thought i would add...The torque reaction is transmitted into the airframe by way of the frictional losses in the drive bearings in the engine/prop. The torque roll therefore is more sensitive to engine RPM than engine load.
Very nice pictures. I do have one question about Torque. If the propeller is rotating clockwise as seen from sitting inside of the airplane, the Fuselage will want to rotate counterclockwise correct? If this is a rolling moment, why are we adding Right Rudder (yawing moment) to counter something the ailerons should be counteracting since it is a rolling moment?
You are asking a good question, and while the counter-rotating effect is present and is said to contribute to left-turning tendencies, it is relatively minimal. Its a great question, but it is relatively minor in the overall picture.
Hi Jakub and dcav8, I know I'm a little late. however, to answer your question about torque while taking off, because normally torque wants to roll the aircraft to the opposite direction of the propeller. Now our aircraft cannot possibly roll while on the ground, the pressure rolling it to the left is actually still applying pressure on the left side of the airplane in a result of more friction on the left tire yawing the aircraft to the left.
@Jakub Svec Greetings! new pilot here. So basically, to avoid this on take off, I only need to apply right rudder? no right aileron? And... It's this left turning effect very noticeable on landing? when you are about to touch the runway? Thx for the info!
what force suck the slip stream around the aircraft in this cork screw motion ??? this is not what happens. most text books have this wrong. look at aerodynamics for navel aviators
Not convincing at all....... forgive me my ignorance, I'm coming from autosport, not aviation. But why is there not a word about tires? 1. Torque. So it produces roll in the opposite direction to prop spin - but how does the roll translate into yaw? I would say it's because left tires are loaded more. 2. Spiralling stream. Again - this gets greater effect when the tail lift up because rear tire has no contact with the ground and the tail has more freedom. 3. Asymmetric loading. Really? Prop spins so much faster than the speed relative to the air that this point is total BS. 4. Precession - see point 2 - the effect is great only because the tire leaves the ground...
Very nice video...👍👍

Great explanaion that a child could understand as well, thank you
The ending is hilarious!
Very brilliant and nice drawings. Even more clear than many animated ones, thank you...
small correction on P factor AOA should be the angle between prop chord line and resultant relative wind and not just a vertical line.
Excellent drawing, excellent explanations, excellent ending!
Straight to the point explanation, incredibly aesthetic presentation. Good job OP
Excellent work, nice touch in the end.

Thanks. Nice vid.
Great Video! Good Explanation
Great video lesson. Thank you sir for posting!
Extremely great video, I for some reason couldn't understand gyroscopic precession and your illustrations really helped!

Very good explanation of p-factor! Excellent video. Thanks you.
great videos ! Thank you very much !
very good explanation. thank you.
great illustrations
Thank you. This is a great vid ever, easier to understand :)
Thanks a lot for the info! I really liked the vid.
I Found This Very Helpful
Thank you.It is great.
Thank you!
You're the man
What is the reason why AoA upward much smaller than AoA downward as you said in 4:29? Shouldn't the AoA will be same for both?
Thanks man, awesome.

LEVEL: Commercial multi engine certificate, airplane
The yaw tendency is not due to torque effect, rather due to P-Effect, creating asymmetrical disk loading, and due to slipstream effect.
@@DFW2017 correct !!!
So in English built airplanes with clockwise propeller rotation....you use left rudder to correct for P factor??
very neat :) ! thanks
Great job!:) Made me smile a lot in the end - I am Russian))))
thank you

Thanks
The vide really helped!!
Due to asymmetrical loading will there be a right-turning tendency while declining?
I would say so, yes. And the same for gyroscopic precession. So really only 2 consistently left turning tendencies.
Great ending lol
Great video man! Too bad you only did a few of them

lots of left turn tendencies

4. Precession - see point 2 - the effect is great only because the tire leaves the ground...
