DO AIRPLANES ADJUST THERE FLIGHT DOWNWARDS TO ADJUST FOR CURVATURE
Let's say you fly at 2 mach speed (1500 miles/h) = 1500/60 = 25 miles/min...8* 25^2 = 5000/12= 416.66 feet = 126m/min...126/60 = 2.1m per second...So, you have to nose down your airplane 2.1 meters (6,93 feet) PER SECOND....If you applied this same simple calculation for SR-71 (Black Bird) aircraft which flies at 3.2 mach speed (3840 km/h), you would get next result : Black Bird pilot should nose down his aircraft 5.3 meters EVERY SECOND in order to stay "level" in relation to the spherical shape of the earth...
1. I know you haven't had the opportunity (up until now) to read this quote :
Since you don't understand how aircraft trimming works, as a PSA for you and other's I will try and explain it. All aircraft are armed with something called a "Trimming" system. It's a set of tabs on the vertical and horizontal stabilizer of an aircraft. When a pilot is at his cruising altitude, he "Trims" the aircraft. There is a wheel inside the cockpit that you roll forwards or backwards and this adjusts the trims on the wings of the aircraft. This changes the way air or wind travels over the shape of the wing; Thus creating lift - up or down in altitude. Autopilots also can automatically trim the craft for you but you must engage it manually. This way, the aircraft hold's it's altitude without descending or ascending. This relieves the pilot, as well, of back or forward yoke pressure. Once the aircraft is trimmed, it's trimmed and will hold it's altitude, Mean Sea Level (MSL) all day long (Weather permitting). If there was a curvature to the earth, the amount of altitude loss would not only be visually noted on the altimeter but your body would feel pressure of constant G force as you would have to push the nose of the craft down to hold your altitude along the curvature of the earth. If this was a automatic system, passengers in jet's would have a noticeable G effect happening to their bodies because of the speed of the aircraft having to constantly descend to maintain constant altitude. (G-force) Even IF an aircraft's gyro did automatically compensate for the curvature of the earth (Which it doesn't), you would be constantly fighting to properly trim the airplane as the craft would be constantly trying to adjust it's altitude to deal with the curvature of the earth itself; Assuming you are manually flying the aircraft.?
2. There is a very simple way how you can check if "Schuler tuning" is pure imaginary concept that has nothing to do with reality : put side by side two different gyros, one gyro which is allegedly embedded into Schuler tuning system, and another gyro which works independently of any other system or device. If you can observe significant deviation (or any deviation at all) in functioning (maintaining-indicating level flight) of these two gyros (while flying in a straight line - certain number of miles) then you will be able to come back here and before all of us solemnly testify that you have succeeded to measure the curvature of the earth. Otherwise, you will be able to admit to yourself : i have finally found what i was looking for : a convincing proof for the flatness of the surface of the earth! One thing is sure : schuler tuning doesn't apply for the purpose of compensation of the non existing curvature of the earth. Is there some other application for this system (wander-azimuth - gyrocompassing for instance) i don't know, and i don't even care. All i know is what i have already stated : Schuler tuning has nothing to do with the alleged curvature of the earth. Just use your reason, that's all it takes.

3. A few interesting comments with which you should be acquainted :

Yes. I hold a airframe & powerplant certificate & have since 1991. Also started as aviation electrician-AE IN navy in 1977 where troubleshooting systems down to components was an everyday all day. When you veer from straight & level the logic system sends an "error signal" that's shows as an indication - whatever it may be. Zero error signal is "plane" is true on all axis. Period. Now, I haven't been in this field for 20 plus years & thanks for reminding me of a truth I already knew!! Thx & cheers!?

who ever is talking here...this person tells the truth. I am an an older guy and learned to fly 40 years ago. A Gyro axis does not move if you move the reference frame (Fuselage) around it. Foucault, Newton,Tyson, Sagan, Einstein and all this other NASA, ESA, MAFIA Freemason Idiots are keeping you stupid by teaching you sheeple wrong stuff.?

I never really thought about this before, but on every flight I have ever been on, no matter how long or how short, there is always the same progression, the take-off, then the climb in altitude, then the leveling off, then the descent which begins about 10 minutes before landing.
There is never any change in altitude mid-flight unless the pilots has to climb in order to avoid a storm or turbulence, and you can feel the slightest change in the planes trajectory right there is your seat, even at night or with the blinds closed, so visuals do not factor into your sense of motion and direction. I think we all have a great sense of the slightest change in our flightpath in the air, I know I can feel the slightest banking to left or right , and up or down, everyone can feel that , right?
.
So if I am on a 12 hour flight between London and Sao Paolo for example , why does the plane flight completely level after climbing for 10 minutes after take-off and descending 10 minutes before it lands.? At some point it must follow the curve of the Earth, right? How come we can never feel it? Logically the plane flying level for 12 hours should end up out in sub orbit if it does not follow the curve of the Earth, right?
So how does that work unless the land under the plane is also level for the 12 hour flight? It's not like the pilots can adjust the length of the climb and descents which are always about 10 top 15 minutes before you land ( easy to remember that one because of the landing and bathroom notices the FA's announce before every landing )

+Rab Downunder The gyros I worked on were in a vacuum case and they sat on a fixed place in the plane. There was nothing to correct except for the 15 degrees per hour of the earths supposed "rotation". This is related to longitude position or East west movement in relation to magnetic north. For coordinated turns and smooth flight , accelerometers are used. But these do not affect the gyro. So, as far as I remember, the gyro did not receive any correction for the curvature of the earth.?

..all I can say is that, i have performed similar tests with gyro, aligned north/south and left spinning on my work desk(electrically powered) from 7AM to 3PM..no offset at all on gimbal..so if earth is spinning, offset should be visible..tests performed in Singapore which is basically equator, so if earth is indeed spinning, offset should be easy visible in 8 hr of gyro spinning here..?

When i started my 25 year USAF career, I was an Automated Flight Control Systems Specialist (autopilot). The system had a pitch up command for coordinated turns so that when the aircraft banked and the wings lost lift the resulting altitude loss could be prevented. There was also pitch up and down commands for terrain following, but no pitch commands to account for the curvature of the earth. If there were then there would have to be a continuous pitch down command to account for the earths curvature. I worked both on the flight line (on the aircraft) and the back shop so I got to learn the complete system and can tell you that there was never any signals to account for the curvature of the earth.?
