No, gyroscopes are independent of gravity; they work on centripetal forces. It is basic physics.

An artificial horizon, or attitude indicator, is a flight instrument that indicates the aircraft’s orientation relative to Earth’s horizon and gives an immediate indication of the smallest change of orientation. An artificial horizon utilizes a gyroscope to detect the change of orientation and pendulous vanes to continuously correct the orientation relative to the level.

Flat-Earthers claim that an artificial horizon should drift over time if the airplane is flying over the spherical Earth because the gyroscope will eventually drift and no longer points toward Earth’s center. In reality, an artificial horizon has a self-correcting mechanism, keeping the gyroscope upright if it is displaced for any reason, including by the aircraft’s motion following Earth’s curvature.

Your proof the earth is flat is using a flight instrument that uses a gyroscope and corrects for the known earth’s curvature with gravity and pendulous vanes?

Well, that’s ignorant and embarrassing on your part?

Altitude on the ground is the known altitude before a flight goes up into air.

When at altitude, they go into level flight,

Level Surface: A level surface is a curved surface in which all the points are at the same distance from the earth's surface. The continuous surface that is perpendicular to the earth's mean spheroid is known as a level surface.

DOES A JET PLANE CONSTANTLY ADJUST ITS NOSE DOWN TO FOLLOW THE CURVATURE OF THE EARTH?

This is an interesting question. A plane will fly at a constant altitude and will follow the curvature of the earth and would not gain altitude during a level flight.

For instance, if a plane is cleared to maintain 35,000 feet, by regulations, the pilot must maintain that level based on a standard barometric pressure setting (29.92 inHg or 1013 millibars)   Hence it would stay at that altitude (FL350) because the pilot is either controlling the plane manually or has engaged the autopilot to achieve that.

There are two basic instruments that enable this procedure – an altimeter and a vertical speed indicator (VSI). The VSI provides short term changes in pressure and indicates whether the plane is climbing or descending. These changes will give an indication to the pilot so that he would level the plane to maintain 35,000 feet. He will adjust the controls very slightly by use of the elevator and trims. This can be performed automatically by the autopilot as well. As such, the flight controls are constantly moving very subtly to maintain the correct attitude.

You said that, if the plane was trimmed for a straight and level flight, it would ‘gain altitude’ while flying as the earth surface ‘fell away’ due to the curvature of the earth. Well, that would probably happen in a perfectly motionless atmosphere where the plane would fly dead ahead, and over time gain altitude (provided it has sufficient thrust) as the earth curves away from under the airplane.

In reality, a constant altitude must be kept using the standard pressure and that means a fixed distance to the earth center of gravity is maintained, making the path of the plane a curved one.

So, a plane is not flying a straight line – geometrically speaking!

Are you referring to the gyroscope in the artificial horizon?  You get it’s not a plane gyroscope.  You understand it’s a system of mechanisms with a gyroscope?  Mechanisms used to correct errors inherent to gyroscopes?  Pretty smart creating a flight instrument that self corrects errors inherent to gyroscopes?

When at altitude, they go into level flight, not as ascent or a descent, at same altitude along the flight.

Planes don’t need to measure their various heights above Earth,

Planes don’t need to measure their various heights above Earth

Air flows over Earth in a flat path, of course.

They have nothing to prove it exists, cannot demonstrate it exists with any objects on Earth, and proves it’s just bs.

a constant and steady descent

Planes don’t need to measure their various heights above Earth, it has mountains and undersea bottoms of ground, and planes don’t need to measure them, each has an altitude as well, sea level is 0 feet altitude, planes are set for whatever altitude on ground, they don’t measure over all the rest of Earths surface, which varies over the entire surface, but is all a flat surface at 0 feet altitude or sea level.

Air flows over Earth in a flat path, of course. We know what happens if we don’t travel level to air, it conflicts with the level flow of air, in normal conditions, and creates turbulence, and the air always wins that battle, every time.

They’ve now made up a most ludicrous and nutty pack of nonsense ever told to us.

Of course, everything is solved by their greatest bs story they had made up long ago.

They have nothing to prove it exists, cannot demonstrate it exists with any objects on Earth, and proves it’s just bs.

Which they use as an ‘answer’ for everything that they cannot actually account for.

Curved surfaces and curved flight paths would certainly be measured for as a curve, if there was a curved surface or curved flight path, which would be from the plane itself, a constant and steady descent, which is perhaps 3 or 5 feet per minute of flight at 500 mph, and we would always fly planes in constant descents, even for short distances. The whole Earth would be curved, all over it, every distance on it.

There is nothing about your made up force to begin with, it doesn’t exist, that’s why they cannot ever prove it exists or demonstrate it exists. If we can prove and demonstrate magnetic force exists, we’d surely be able to prove and demonstrate your ludicrous force exists too, but even easier than magnetic force is.

We have a made up force that pulls down all things from air to the surface while for absolutely no reason or logic, adjusts its strength to each objects mass, and pulls them all down to the surface at the very same speed!

It gets worse from that point, but I digress.

Planes measure for level flight in air, which is a flat and straight and horizontal path over the Earth, which is also flat.

There’s no proof of anything in their excuse even exists to start with, so it’s ridiculous that they use such crap in combination for their story.

Nobody on Earth knows what is under a few thousand feet of Earths surface. Making up a ‘core’ in the center of their ball Earth is complete nonsense, without a shred of proof for it being true!

Then they add in their made up bs story of a great universal force which exists in all things, which pulls in other objects with less of their made up force. Except they can’t ever prove it, which would be very easy to prove, if it wasn’t just made up and told was true!

Hey, how about using our instruments and their measurements as indicated on them as true, as real? That’s better than making up bs stories that never work at all.

Our instruments measure as indicated, that’s why we built them, and why we have gauges on them to measure things for us.

Imagine how that would ever work! What exactly are the instruments on planes measuring here? Why would they measure for something that we don’t even know about in the first place?

‘Ok Ralph, I want to let you know that when you’re flying a plane, the gauge will measure for level flight, but we don’t know what it really means by that. I heard it’s now called level to Earths curvature and our instruments are hit by waves of gravity in Earths core, and makes the read level over the ball Earth surface, or maybe it’s curved air pressure, or both, I have no idea.  Anyway, forget what I just said, it’s bs anyway. We know what level means, and know how to measure for level, which has nothing to do with any curves’

You’re babbling.  The VSI doesn’t change if the aircraft stays at a specific pressure band correlating to an altitude.  And the only way to gain altitude is to increase flight surfaces and increase power.

The VSI only reads when the plane leaves a pressure band correlating to a certain altitude. 

It reads any change in air pressure that isn’t level or horizontal in air, within a few mm or so, and the gauge moves up or down.

If the Earths surface or air above it was curved, it would have to curve over the whole surface, which would be extremely difficult to measure and account for, and would require very different instruments than we use today. 

They don’t measure for flights of planes over a ball Earth, m

within a few mm or so,

Section 2. Barometric Altimeter Errors and Setting Procedures

https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_2.html

If the difference from the known field elevation and the altitude read from the altimeter is plus or minus 75 feet or greater, the accuracy of the altimeter is questionable and the problem should be referred to an appropriately rated repair station for evaluation and possible correction.

It reads any change in air pressure that isn’t level or horizontal in air, within a few mm or so, and the gauge moves up or down

The most important part here, is how it actually measures for pressure. Around the entire plane, not one tiny point on the plane, in its centre or whatever.

Level is measured over a distance or length or span, between two separate points.

If the Earths surface or air above it was curved, it would have to curve over the whole surface, which would be extremely difficult to measure and account for

Levels measure for only one thing

Over a span of two feet, the curvature would be extremely small

cannot EVER be flat

Planes don’t need to measure their

The design and physics of airplanes is such that they hold a certain trimmed altitude and speed, following the curvature of the earth automatically, even without any intervention of the pilot or autopilot system. Pilots don't have to drop the nose to correct for curvature. The interactive physics simulation of an airplane on this page shows how this works. The physics model and the corresponding behaviour of the airplane are explained. The Source code and the equations are described in detail.

It’s a rather simple experiment.  Just takes coordination.

Activity: Measuring the Earth's Curvature II
One of the first people to make a very accurate measurement of the circumference of the Earth was Eratosthenes, a Greek philosopher who lived in Alexandria around 250B.C. He was told that on a certain day during the summer (June 21) in a town called Syene, which was 4900 stadia (1 stadia = 0.16 kilometers) to the south of Alexandria, the sunlight shown directly down the well shafts so that you could see all the way to the bottom. Eratosthenes knew that the sun was never quite high enough in the sky to see the bottom of wells in Alexandria and he was able to calculate that in fact it was about 7 degrees too low. Knowing that the sun was 7 degrees lower at its highpoint in Alexandria than in Syene and assuming that the sun's rays were parallel when they hit the Earth, Eratosthenes was able to calculate the circumference of the Earth using a simple proportion: C/4900 stadia = 360 degrees/ 7 degrees. This gives an answer of 252,000 stadia or 40,320 km, which is very close to today's measurements of 40,030 km.

With the help of another classroom and teacher who is located far (several hundred miles), to the North or South of you, your class can perform a similar experiment. Alternatively, one student or a group of students who travel for spring break could perform this experiment during their trip.

Seems like an easy thing to do with all the talking head flat earthers over the works with YouTube channels.

But I guess there are several other proofs that already prove’s the earth is spherical.

There is a person on YouTube,
Jos Leys? The individual likes to do computer models and set them to music. 

The individual also shows flat earth modeling vs reality.  Usually for sun and shadows.

You mean we can’t measure for a curve, yet somehow can adjust for it?

Either a curve exists and is measured for, or it doesn’t exist TO be measured for!

If Earths surface IS curved, it has to be measurable AS a curve, with some sort of instruments we don’t even have

The surface of Earth IS flat, so it’s hard to imagine how it would look and how to measure for it.

We’d certainly have to measure for a curve if it DID exist, account for a curve on flights, and so on!
