Very good, very clear. But I am trying to relate this knowledge to the Air India crash when a 747 plunged into the sea soon after take off from Bombay! The Cockpit recording indicated that both sets of gyro indicators , the pilot's, and the co-pilot's, had "toppled", and the co pilot urging the pilot not to follow the defective indicator.
What else could he have followed, I am asking when it is night and the horizon is not visible. There was the magnetic compass,and the shore lights of Bombay somewhere behind. Did the Boeing 747 have two sets of ball and tube full of kerosene so the pilots could turn back safely towards the airport!
It's like one of those old educational videos from the early part of the 20th century in the way the information is presented in simple, but clear and concise manner.
Absolutely Mind-blowing explanation.... I was looking for such of an explanatory video for a really long time. In the last MEMS class Gyro and Accelerometer were discussed followed by a simple experimentation and that is how I am here.... lovely!
@@npc6817 a skid is when you step on the rudder too much. Whenever you are coordinating your turn, you would want to add a little rudder in the direction of bank to counteract adverse yaw. A slip could happen either if you don't use any rudder, or use opposite rudder to your turn. Skids are more dangerous than slips because they put you into a spin-stall condition, whereas a slip is more stable. Some more background info from a pilot, you typically think of there being 3 different types of slips, forward slips, sideslips and turning slips. The example given here is a turning slip, and in practice is used when you want to lose altitude in a turn. forward slips are the same idea, but the airplane is not turning. This is what the gimli glider did as it was coming into CYGM RW33. A sideslip is more controlled. In a true sideslip, you keep the nose pointed towards your target and band your wings in the direction you want to drift. You would then use as much opposite rudder as you need to maintain your nose straight at your target. This is often used during landing as an alternative to crabbing into wind, or even as a transition soas not to sideload the gear.

Awesome video as always. If you guys are still having trouble understanding gyroscopic precession like I was, the PHAK’s example using a bicycle finally made it click for me.
I was just flying in MSFS2020 and I did not even know about the step on the ball thing. It seems I need to binge this videos to learn more about aviation. Great stuff!

Wow this filled every gap from every other gyroscope video. They gloss over how gyros address pitch, yaw, and roll. These animations were perfect and seeing the orientation of the gyro was essential. Thanks for the great animation.
The airflow needed to propel the gyros just shows how one failure can lead to another in a machine as complex as an airplane. Learning how every component works is not just an exciting insight, but a necessary effort for understanding everything that can go right or wrong.
@@hongry-life Yes, but not necessarily to "keep up with the speed of the atmosphere". Lift (the force that holds and airplane in the sky) is inversely proportional to the density of the air. The higher up you go, the thinner the air is, so there's less force pushing on the wings and holding the plane up. To compensate for this, the plane must fly faster (have a higher airspeed), because a faster airspeed is proportional to the production of more lift.
Well, that set of sentences is flawless, so you're doing better than probably 80% of native english speakers. I'm told learning english non-natively is fairly difficult because it's a kind of "fiddly" language, owing to the fact that it's been assembled from many other linguistic styles, and often due to completely unguided and organic cultural amalgamations. Good job.
At 2:08 this is wrong! The air is pumped through hollow gimbals into the spinning gyro itself, from which the air escapes through the ring of jets causing it to spin. If you have omitted the gimbals for clarity, the air should still be piped into the hollow axis of the gyro. Nevertheless, EXCELLENT SUPERLATIVE presentation! Thanks for making it available!
Very nice, only issue I have is that the ball is not deflected by aerodynamic forces. There is no air going through the glass tube to move the ball. The ball is purely moving due to the net acceleration. If you try to listen to the movements of your body you actually don't need a balance ball.
Plenty of modern aircraft now use optical gyroscopes. They are, basically, Sagnac interferometers. They work similarly to the famous Michelson-Morley experiment. The fact that they work at all is proof of the invalidity of the theories of Einstein. And maybe that is why few people talk about it. But they work, and without the luminiferous ether (which Einstein firmly declared non-existent and incongruent with His theories) they should not!
Gyroscopes in attitude indicators have a self-correcting mechanism to keep them always aligned with the local gravity vector. On mechanical gyros, this is based on a pendulum that senses gravity and it opens and closes some air vanes on the wheel so that little jets of air help to erect the gyro. On electronic ones, this is done with accelerometers that measure the gravitational acceleration (not very different from the ones in your smart phone that let it know what is vertical and what is horizontal so it rotates the display accordingly). Anyway, the rate of correction would be very little. The Earth has a circumference of almost 25,000 miles. Even in a fast jet moving at 500 miles per hour, it would take 50 hours to fly around the planet. This means that to make a 360° turn around its lateral axis, an aircraft would have to pitch down 7.2 degrees per hour or a mere 0.12 degrees per minute. This is easily achieved by the self-correction mechanism and the down-pitching of the aircraft, *if it was needed to keep altitude and follow the curvature of the Earth,* would be completely unnoticeable for any person. But pilots *don't* determine, vary or keep altitude based on attitude indicators, they use *altimeters* instead that work by measuring the atmospheric pressure and vertical speed indicators (VSI) to know the rate of climb or descent. Altitude is the vertical distance from the mean see level. A plane aloft is subject to forces like turbulence that are constantly making it drift away from the desired altitude. Altimeters and VSI show that and the pilot or autopilot constantly makes little adjustments to power and trimming, up and down, to stay at the correct altitude. You can see how this self-correcting system looks like in his video: th-cam.com/video/z1QGRPVBZvw/w-d-xo.html You can see a gyro self-correcting in this video: th-cam.com/video/kTXTCqMHyhg/w-d-xo.html
Very nice, these are the old electromechanical gyros, new gyros and the ones installed on commercial aircrafts are the newer laser based ADIRU units from companies like Honeywell. Look them up, they are able to detect the rotation of the earth while standing still at the airport
Sam : "they are able to detect the rotation of the earth while standing still at the airport" Interesting, are you able to provide a source for this? Thanks.
How does this device account for earths curvature as you fly at distances enough to effect your altitude? Wouldn't the display on the gyro start to pitch upward as the plane stays at the same distance away from the ground being that it was calibrated to the level of the runway in which the plane took off? If this device is 100% mechanical, and completely free of the effects of gravity, I don't see how it could adjust its self as a plane flies over the curved earth surface.. For example, if you fly a plane in a strait line for 200 miles, you would be traveling over about 26,650 feet of earth curvature. (based off 8" per mile square which is how much earth is suppose to curve) So at what point is this downward drop of the earth noticed on a gyroscope, being that it's independent of gravity? Some one help me out here, am I missing something?
Hey man. I did some math that I hope is right. To get an error of 1 degree, the plane needs to travel 69 miles. The error will be in downward pitch. If the plane travels for 200 miles, the error will be under 3 degrees. There is a nob on the device shown in the video and its probably for re-aligning when the plane is on the ground. If power is off, then no spinning on the gyro and it will re-align itself. Also, if it was made so that a tick is 1 degree of adjustment, then re-alignment can be done every 69 miles. But say if the pilot does not do this and instead he pitches up the plane to compensate, then the plane would be 0.603 miles higher than the proper elevation every 69 miles, or 0.0087 (46.1 feet) miles higher every straight mile traveled. If the plane travels for 200 miles, then the plane will be 1.75 miles (9229.54 feet) higher than the proper altitude. However, the pilot only needs to see the plane's altimeter to stop this from happening. I think what happened in your computation was that you assumed that the plane traveled completely straight in space. Though the gyro devices circumvents the effects of gravity, the entire plane is still being pulled down and trying to escape this pull requires a lot of energy, likely more than what commercial planes carry. So a "cruising" plane should maintain altitude because there is still a downward pull while it accelerates straight - which is rotational motion. Hope this helps, good question though.
@@bluesteel7874 Thank you for the response! I've gotten very few people who have attempted to explain this. I see what your saying, however this still means that pilots (all pilots who fly at decent distances) will have to make manual adjustments to their instruments in order to maintain there accuracy.. What i'm saying is, I don't think this is actually happening. Sure, in theory this explains what could be happening, but in the real world, do we hear of, or see pilots adjusting the instruments that they rely on to be 100% accurate from the time they took off from the run way? Is that not the point of setting "level ground" on the gyro when the plane is on the run way before it takes off?
@@CarsonKendall I get what you're saying and I cannot definitively answer as I am not a pilot, nor have I seen for myself an actual pilot fly a plane. Here's my theory, the analog devices that we saw are probably used in small planes that cannot travel very far. 1 to 3 degrees is not very noticeable nor consequential in small distances. Large commercial planes with long ranges prolly has a way to automate the adjustment. But the best answer needs to come from an actual pilot as they know the nuisances of the job.
@@bluesteel7874 The correction for the earth's curve is made by pendulous vanes "The pendulous vane system in a vacuum-driven attitude indicator keeps the gyroscope upright. If for some reason the gyro is displaced, the vanes and air jets create a precession force that drives the gyro to erect again, returning it to the vertical."
Out of several videos, you are the only one to explain how the gyro is getting the power to spin. It's still mildly confusing, but I know more now than I did before.
madDragon08 they are normally a perpetual motion machine and spin forever on their own, the shitty ones use air or electric motors but are not properly tuned
A compass has a number of issues the directional gyro doesn't have (see e.g. www.boldmethod.com/blog/learn-to-fly/aircraft-systems/how-your-magnetic-compass-works/). The compass is really only used in DG failure scenarios such as vac pump fail or in planes with minimal equipment to begin with (vintage, experimental).
Good video! I just have a quick question. When they say the indications presented by the miniature aircraft of the turn coordinator is indirect indication of the bank attitude, what does that mean? Especially the indirect indication part? Thank you!
Gyroscope effects are used is many engineering calculations of totations parts, and instruments used in aviation, space, marine and other industries.Gyroscope theory still attracts many researches who continue to discover new properties of gyroscopic devices.
You explained the gyro and all these instruments in 7 minutes better than they could in 130 pages in the book.

So, to my knowledge, a slip is the aviational equivalent of understeer, and a skid is the aviational equivalent of oversteer.
thats what exactly came to my mind!
so in order to drift a plane you must _not_ step on the pedals?

Adding the 30 degree tilt to the gyro for the turn coordinator was a pretty ingenious little tweak.

But say if the pilot does not do this and instead he pitches up the plane to compensate, then the plane would be 0.603 miles higher than the proper elevation every 69 miles, or 0.0087 (46.1 feet) miles higher every straight mile traveled. If the plane travels for 200 miles, then the plane will be 1.75 miles (9229.54 feet) higher than the proper altitude. However, the pilot only needs to see the plane's altimeter to stop this from happening. I think what happened in your computation was that you assumed that the plane traveled completely straight in space.

The correction for the earth's curve is made by pendulous vanes
"The pendulous vane system in a vacuum-driven attitude indicator keeps the gyroscope upright. If for some reason the gyro is displaced, the vanes and air jets create a precession force that drives the gyro to erect again, returning it to the vertical."

A compass has a number of issues the directional gyro doesn't have (see e.g. www.boldmethod.com/blog/learn-to-fly/aircraft-systems/how-your-magnetic-compass-works/). The compass is really only used in DG failure scenarios such as vac pump fail or in planes with minimal equipment to begin with (vintage, experimental).
how does the artificial horizon perform on long flights around the globe?
doesn't it show pitch movement, where in reality is none?
The pendulous vanes keep the axis perpendicular to the local ground
Thanks for the information. I learned a lot.
studying for a ppl have never been this easier
Ive nothing to do with mechanical/aeronautical engg but man this is freaking awesome!
Wow! Excellent!!!!!!!
Good video! I just have a quick question. When they say the indications presented by the miniature aircraft of the turn coordinator is indirect indication of the bank attitude, what does that mean? Especially the indirect indication part? Thank you!
Gyroscope effects are used is many engineering calculations of totations parts, and instruments used in aviation, space, marine and other industries.Gyroscope theory still attracts many researches who continue to discover new properties of gyroscopic devices.
6:55 Jeez that’s sounds painful. I don’t wanna be a pilot anymore
