Is The Earth A Flat Round Disc or Is It a Round Spherical Globe?

[tak22]

The density of the air is governed by the strength of gravity, whether the source of gravity is the flat plane or the spherical globe. The strength of gravity varies with the altitude above the ground (not exactly, but it makes little difference). 

So, the plane as a whole will pretty much automatically hold the same altitude above the ground in "normal" conditions. That is, with no "touches" on the controls needed.

Thanks Bill and CANGAS for the information on how a plane maintains level flight. My suggested experiment was to ignore "normal" conditions and fly the plane on a 'level' trajectory while compensating for the influence of gravity and air pressure. I don't know how the pilot would do this, sight on a star at night?

If a plane is traveling 500 mph, the earth is falling away at a rate of 2,775 feet per minute, in a globe model. If autopilot is off, the pilot must reduce altitude by 2,775 feet per minute or 46 feet per second to maintain 35,000 feet.  A 46 feet per second drop would be noticeable to the passengers. The theory that somehow gravity miraculously keeps the plane in a sort of auto orbit with the atmosphere is preposterous. The plane is not traveling with an atmosphere locked into the earth's 1000 miles per hour rotation. If so, how then can it easily land and also adjust to the angle of the axis? Impossible!

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, thus the earth must be flat.

The truth is no pilot will admit to what he sees with his own eyes that the earth is actually flat for fear of being sacked instantaneously as many whistle blowers will testify too.

The wings are not level with the horizon, that artificial horizon gauge shows a bank to the right...sheesh.

A horizon indicator is how a planes fly level and maintains a certain altitude above sea level.  I can find you an image of a horizon indicator which shows the wings are 100% level with the horizon, instead of 99.98%, if you like.  Is that necessary?  Will that change anything?  Of course not!  You made a poor argument as usual, so get over it and stop balling!

This sort of reminds me of the "Intelligent Design" people that believe that the Earth is 6000 years old, including the dinosaurs.

There is scene in The Sopranos where Tony says, "Like the Flintstones?"
