Where was the explanation?

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.

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?

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.

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.

@@FS2K4Pilot That would simply increase the gyroscopic forces. More rigidity and more precession. The formulas for gyroscopes include mass as a factor.

Yes. This is the concept of counter-rotating propellers on a multi-engine aircraft.

A single engine plane with a clockwise turning prop, as viewed from the cockpit, yaws left from precession while climbing at high power settings.

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.

If you watch the entire video on the double hammerhead I talk through this in more detail: kzfaq.info/get/bejne/bpyAg7KDubysfnk.html

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!

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.
