I spent about an hour studying principles of flight Gyroscopic Effect and I was still scratching my head. Your video was 2 minutes and I get it now lol.
Istg, it says all these words at me and I just can't seem to imagine it at all, I had a terrible understanding of how it worked. I needed an actual visual representation but all I normally got when studying as just pictures, a 2d format. I needed a 3d view of how it worked
It's spinning in the correct direction, but as pilots we are taught gyroscopic precession is a left turning tendency even though it technically isn't. Presscion's relations to other forces are what actually cause the plane to go left. It is also more oriented towards tailwheel planes who have to pitch down on takeoff
Hey there, thanks for the video. I've been doing some gyroscopic analysis on your video, mainly the end bit when you push the plane with the straw. For some reason I'm getting the theoretical inverse where the plane should move in the opposite direction. Could be my error, but are you certain that the gyroscope is spinning clockwise when viewed from the tail? My answers for your gyroscopic movement seem to match your gyroscope spinning counterclockwise - quite the conundrum! Thanks 😄
The torque is always applied 90 degrees ahead. 1:37 For stick forward, the plane pitches down. Torque is pushing forward on the propeller from 12 o’clock and shifted 90 degrees clockwise due to gyro precession would create a torque pushing from 3 o’clock on the prop. Pushing it from the right causes it to turn left.
So is it when you pitch up the aircraft yaws to the right and when you pitch down the aircraft yaws to the left, but when you yaw to the left the aircraft pitches up and when you yaw to the right the aircraft pitches down??? Anyone please help!!!!!
@@ssairshows Because on a rotary engine the entire engines spins, so instead of just the gyroscopic tendencies of perhaps 50 pounds of propellor, you have the gyroscopic tendencies of several hundred pounds of propellor and engine.
@@FS2K4Pilot That would simply increase the gyroscopic forces. More rigidity and more precession. The formulas for gyroscopes include mass as a factor.
Some feedback: this video was helpful as others have said and gave a very easy to see example. But you just gave us the dots. You didn’t really connect them with some sort of explanation.
Thanks for your comment. The purpose of this video is to simply show how rudder and elevator (cause) result in an effect on yaw and pitch of the plane because of the gyroscopic precession of the propeller. It's something every pilot has been taught mainly in the abstract; however, few can visualize. Can you be more specific about what explanation you are looking for?
@@ssairshows I think he's looking for an explanation that explains gyroscopic precession and the plane's behavior. However, you did say this is just a clip from another video that explains it further. Also, congrats on gaining a subscriber today!
P-factor is just one factor of the left yaw effects from the propeller. When the downward sweeping blade is at a higher angle-of-attack than your upward sweeping blade such as when climbing, the downward sweeping blade creates more thrust which contributes to making your airplane want to yaw to the left. There are four factors that contribute to left yaw and in low powered planes like Cessna no one factor is very strong; they come together as a group to influence yaw to the left that is noticeable to the pilot particulalry during high power and low airspeed combinations such as when climbing.
It's explained through Physics. Gyroscopes attempt to remain rigid in space. However when a force is applied to it, the actual reaction of the gyroscope occurs as if that force was applied 90 degrees later (in the direction of rotation). That is called Gyroscopic Precession.
I wonder what if an aerobatic plane pilot that flew right prop planes will take controls of a left prop plane? That's probably gonna be a reeeaaal brain-twister!
This happens every time someone used to flying behind a Lycoming engine flies a Russian plane (Sukhoi, Yak) with an M-14 radial engine. You hammerhead with right foot and inverted flat spins can only be done with left foot.

This explanation remains undefeated.
Where was the explanation?
This is exactly the visual I needed to see. It just opened up a world of awareness flying and making each turn with more precision. Thank you so much!
It’s one thing to understand it but another to physically see it. Great video series!
Best video ever. I struggled with this concept for a long time. In 2 minutes I completely understand it. Thank you!
Reading about GP is confusing, this explanation is the best yet!

I never thought I'd see a video with ZERO dislike. Really shows how awesome this video is. Let's keep it this way.
You always had a knack for explaining things! Glad to see you are well!
I think this is the best video I have ever seen. Even better than those "well known" flight schools.
This really helps my understanding of the lazy eights, especially when turning to the right!
Mannnnn what the hell this is fucking so amazing to understand. People need to be more like you
Best video out there to understand how it works. Thank you!
Visualization made this really easy to understand
Thank you so much! I'm studying for my Airframe AMT test right now and this helped me a ton!
What’s is the affect I mean it on the string
@@fennec7970 i know this is late, The string in this case is the CG of aircraft , so all forces tend to create moment abt the string.
Again great explanations with sponsorship possibilities
Is your gyro spinning the opposite direction of a standard prop? The resultant forces from your applied forces would seem to indicate so.
It's spinning in the correct direction, but as pilots we are taught gyroscopic precession is a left turning tendency even though it technically isn't. Presscion's relations to other forces are what actually cause the plane to go left.
It is also more oriented towards tailwheel planes who have to pitch down on takeoff
@@userfivehundred3043Hi!
does that mean itself actually is not the major factor causing Left turn tendency but combined with others it would?
The thought that I had when watching this was "are you kidding me, why is there so much that goes into flying a plane." Very informative video.
Easy, simple and fast to explain, thank you!
Excellente démonstration. C’est maintenant évident. Merci

Hey...I AM a professional!
The torque is always applied 90 degrees ahead.
1:37 For stick forward, the plane pitches down. Torque is pushing forward on the propeller from 12 o’clock and shifted 90 degrees clockwise due to gyro precession would create a torque pushing from 3 o’clock on the prop. Pushing it from the right causes it to turn left.
Yeah getting the same error, phak says this is a left turning tendency during climb.
best to have counter rotating props?
So is it when you pitch up the aircraft yaws to the right and when you pitch down the aircraft yaws to the left, but when you yaw to the left the aircraft pitches up and when you yaw to the right the aircraft pitches down??? Anyone please help!!!!!
Was Chewy a sponser of this video?
Wonder if you could use counter rotating gyroscopes to control pitch and yaw
Hi could you link what motor you used?
what if You put two gyros in opposite direction to each other. They should cancel out but we will have stability ???
Yes. This is the concept of counter-rotating propellers on a multi-engine aircraft.
I don’t understand why we need to push right rudder on takeoff then if precession makes the airplane yaw right while climbing?
A single engine plane with a clockwise turning prop, as viewed from the cockpit, yaws left from precession while climbing at high power settings.
This is awesome (followed a link in the Gold Seal courseware).
This was a big issue in WWI airplanes with heavy rotary engines and big heavy propellers.
I’d like to hear your thoughts about how this would affect the handling of rotary-engined WWI fighters.
Why would the engine type matter? The prop is a spinning disk, the engine - no matter what type - is the source of torque.
@@ssairshows Because on a rotary engine the entire engines spins, so instead of just the gyroscopic tendencies of perhaps 50 pounds of propellor, you have the gyroscopic tendencies of several hundred pounds of propellor and engine.

this is brilliant..
Fascinating
thank you, very useful and entertaining!
Awesome video Spencer!
great explanation!!!!
The gyroscope was turning right. What would happen if the gyroscope was turning to the left?
The opposite reactions would occur.
Well explained 👏👏
Thank you
wow thank you so much!! great video

THANX A LOT
So somehow it opposes the p-factor?
