The flat earth conspiracy

Aircraft don’t measure distance to the ground. They maintain altitude by using a corresponding barometric pressure. If a jet is maintaining a specific altitude, why would it not follow the curve of the earth?


Planes are not 'dropping' 8 inches every mile (per se), they are flying along the constant curvature of the gravity equipotential, while constantly adjusting pitch ever-so-slightly by means of the elevator trim setting which controls the pitch RATE of the airplane. ANY deviation from that rotation results in the plane climbing or descending which immediately shows up in the Vertical Speed indication and power settings would be adjusted accordingly. This constantly rotates their 'tangent' so there is no 8" to drop at the end of each mile, it's a constant, smooth, and VERY SLIGHT curve that presents no problems for pilots, and would be virtually undetectable in the face of other forces acting on the airplane, even at 500 mph. The plane is simply tweaked for near zero vertical speed and that's all that is required.

The Attitude Indicator is very clearly compensating for all kinds of precessional forces acting up on it and to remain accurate over the longer term must be tied to the gravity potential as well (so it remains vertically aligned over time, reacting only to sharper movements of the airplane over the short term).

'Gravity' is nothing more than an invented fairy tale, of a magical force, which does not even exist, and no proof it exists, I've explained this to you over and over again. Despite that you cannot make arguments based on fantasy forces you create, you have nothing else, and keep on repeating your worthless argument where you need magical fantasy forces to support your argument.

Why would you need fantasy forces, if the Earth was actually round? Only if it is NOT true, do you require magical forces in arguing for it. The flat Earth argument does not invent fantasy forces like you do, it has scientific instruments that MEASURE the Earth as flat, every single day.

Any idiot can invent some bs magical force to explain ANYTHING, and it doesn't change the facts, the evidence, the reality, in any way. Spouting it over and over doesn't change the facts, no matter how much you say it. Any such argument is pathetic, absurd, and completely desperate.


I don't care if you call it a 'slight' curve, or a 'gentle' curve, it is simply a curve, adding subjective, personal terms to it won't help your argument. A curved path is always curved, no matter how slight it may be. It is a curve, period.

1 mile is 5280 feet. Your 'curvature is 8 inches per mile, along a flight

A plane with a cruising speed of 500 mph covers 500 miles of curvature each hour, 500 x 8 inches, is 4000 inches of curvature flown over in one hour. Or, 60 minutes covers 4000 inches of curvature. So this makes 66.66 inches, or 5.5 feet of curvature flown over each minute of flight.

This means a plane would have to ascend at a rate of 5.5 feet per minute, to account for the curvature, and remain at altitude.

It's funny that those of you claiming curvature exists, never calculate for how a flight would work, for very good reason - you know it would prove my argument, which it does.

While you would certainly wish that a flight over curvature cannot be calculated, I'm once again showing you it can be calculated, with your own curvature numbers, and actual cruising speeds of planes.

We find a plane would have to descend constantly, at a rate of about 5.5 feet per minute, to account for curvature.

I suppose this pilot doesn't know how to calculate for curvature, because he calls it a 'slight, slow pitch downward'.
His 'slight descent' would be 5.5 feet per minute descent, throughout every flight, but I suppose he doesn't know that either, he only flies the damn thing around!

And here is why your pilot doesn't calculate his 'slight descent', because the descent would be about 5.5 feet per minute, which would be measured by the VSI, which DOES measure descent (and ascent) in feet per minute!

So once again, you try to ignore the instruments on planes, which measure a flight. You already tried to twist level flight measurements into being a CURVED flight, as we know.


Instruments prove the Earth is flat, despite your attempts to twist, and ignore, what they measure on flights, with extreme accuracy. Pilots rely on these instruments during flights, while you twist and ignore them, because your ridiculous ball-Earth argument can't use actual evidence from instrument measurements. It completely depends on having a magical fantasy force, that has magical powers, making it one of the most worthless, ridiculous arguments of all time.

Well done!

You

Ok?

You

And here is why your pilot doesn't calculate his 'slight descent', because the descent would be about 5.5 feet per minute, which would be measured by the VSI, which DOES measure descent (and ascent) in feet per minute!

Why would it be measured by the VSI if the pilot or the automatic pilot is set to fly at a specific altitude based on barometric pressure
Again....

ANY deviation from that rotation results in the plane climbing or descending which immediately shows up in the Vertical Speed indication and power settings would be adjusted accordingly. This constantly rotates their 'tangent' so there is no 8" to drop at the end of each mile, it's a constant, smooth, and VERY SLIGHT curve that presents no problems for pilots

Again. If the controls are set to maintain a specific altitude by barometric pressure, and the power settings and vertical settings are set to maintain that altitude. why would there be any readings on the VSI? When the VSI helps prevent ascending and descending from the desired altitude. While compensating for other forces like turbulence, and the flight controls controlling to a specific altitude. Which in reality cannot keep nailed to an exact altitude. The controls are going overcorrect with too much altitude from time to time. The controls adjust to lower the altitude. The controls from time to time will over lower the jets altitude time to time, and raise the jet back to the set altitude. All the while fighting turbulence, storms, shear winds, cross winds, tail winds, head winds, icing of control surfaces, and who knows what else. The curvature of the earth is only one of several items a control system, pilot compensates for. And gets lost in the noise of several factors.

Its like measuring the rate something drops to the surface of the earth by using a paper airplane by throwing it off a hundred story Chicago building on Chicago’s windiest day.

How Does A Vertical Speed Indicator Work?

www.boldmethod.com...

How It Works: Differential Pressure
So here's how it all works. Let's say you start climbing. As you climb, your static pressure decreases, and as it decreases immediately in the diaphragm. But the instrument casing is a different story. Since the calibrated leak lets air out slowly, it creates a higher pressure in the casing than the diaphragm. When that happens, it creates a pressure differential, the diaphragm is squeezed down, and the gears connected to the VSI needle make it move up.

For a vertical speed indicator that works off differential pressure, why would it read a drop in altitude if an airplane is maintaining its altitude by the corresponding barometric reading?

a reply to: turbonium1

Another source....

A variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI)

Snip

Newer variometer designs directly measure the static pressure of the atmosphere using a pressure sensor and detect changes in altitude directly from the change in air pressure instead of by measuring air flow. These designs tend to be smaller as they do not need the air bottle. They are more reliable as there is no bottle to be affected by changes in temperature and less chances for leaks to occur in the connecting tubes.

en.m.wikipedia.org...

Again. It woks off pressure. Not actual measured distance from the ground. So if an airplane is maintaining altitude by barometric pressure, and there is no change in altitude to change barometric pressure, then the VSI is going to stay steady.

Another thread that contradicts you imagined workd view.

What's up with those satelites?!?!
www.abovetopsecret.com...

If you have any credibility, looking forward to you posting on ATS at “ What's up with those satelites?!?!” To tell everyone how you think Starlink satellites are not really in orbit around earth.

Or do you finally understand tickets really do place man made satellites in orbit around earth.

I saw some of these last night at the same time as an ISS pass.

They arrived exactly at the publicly stated time and my mother watched them at the same time 20 miles away.

a reply to: OneBigMonkeyToo

so you admit - your mother is a NASA shill too then ???

caveat - this post is a re-work of an earler - deleted post - where-in i swore at idiots

calculating the visibility of the sun - on a flat earth [ hypothetical ]

the flat earth delusion - claims the sun rotates above the equator on the spring and autum equinoxes - at an altitude of 5000km [ 5 thousand ]

they further claim - that the distance from the north pole - to the alledged " icewall " = 20000km [ 20 thousand ]

now people who are capable of working to a scale other than 1: 1

can extrapolate from this ie

a freestanding structure - like the burj khalifa [ height 828m ] - f1 = 15m ASL

so - basicly - the tip of the spire = 833m ASL

so simple maths 833 / 5 000 000= 0.0001666

thats our scale ration - for this experimen

now our " virtual north pole for this ecperiment = 1666 m away [ just over 1 statute mile ]

and the radius - to the virtual alledged " ice wall " = 3332m

now lets put that on a map



point - VNP = virtual north pole
the red circle represents the equator
the purple - the alledged icewall
and the tower is " above " the equator - as we has set the date to an eqinox

can we see the tip - from beyond the " ice wall " - yes we can



the red arrow points to the tower - and the POV = dubai route 66 3.4km from the tower


ooops - the flat earth delusion fails - with just one simple test

this can be donewith any big structure - and simple maths and cartography

and it uses the flat earth proponents own claims

they dont do science - but we do

a reply to: ignorant_ape

We're all in on it

True fact: sunset at the top of the Burj al Khalifa is later than at the bottom. If the sun is just moving further away this should not be possible.

a reply to: OneBigMonkeyToo

Shhh. Did you get your government check this month? I heard we are all going to get another check soon in the USA. Mums the word.

a reply to: turbonium1

Turbonium -- you in luck there is free access to the world knowledge - you might even find a map of the flat earth

You know you are right the plane in flight is actually descending every minute you just have to remember

the art of flying is diving at the ground and at the critical moment be distracted and miss.

Douglas Adams

So if no engine plane falls, out of the sky. Not due to gravity as you said

'Gravity' is nothing more than an invented fairy tale, of a magical force, which does not even exist, and no proof it exists

But it just does for some reason you haven't described.

However, in a globe world the pilot just has to use the engines enough to move forward and only fall 5.5 feet a minute which due to a curve in the earth leaves it at the same height. no magic just fall prevention.

In a flat world Pilots fly flat lines but use even more power to prevent any falling.
.

But I'm still having a problem in your flat world with the sunlight / flashlight.
No seeing it can you upload an example diagram?

After all it isn't some thing I can Google is it?

P.S.
So again can you stop with trying to debunk globe earth theory using man made technology and just stick to proving flat earth using the basic land and sun theory please.

Why is this thread even still going? A few pages back turbonium1 offered a very simple experiment that conclusively proves how pants on head idiotic the flat earth faith is . . .I mean, the flat earth faith is literally proven invalid every time the sun rises and sets, but turbonium1 gave us a really lovely experiment and all you need is a coffee table and a flashlight .

I find it very telling that Turbo hasn't commented on the forum that this ongoing very sad joke of a thread is in. I also see that Turbo is playing his greatest hits yet again, as he tries to pretend that those greatest hits haven't been pulled apart and made fun of so many times that it's ridiculous that he can deny that it hasn't happened.
I think that Turbo's made a bet with someone on how long he can keep this thread going with a straight face on his part. I mean, the fact that he thinks that the Sun goes around the Earth and that therefore it must be a very teeny tiny ball of fire is amusing.

That's kind of mean to call Turbo "it" don't you think?

In all fairness. By Turbo’s logic. We don’t have a video of Turbo rocketing into space. So Turbo does not exist. Until Turbo can post video that shows otherwise. If Turbo does, then just claim bad CGI.

I thought something along those lings a long time ago... but after pages and pages of dealing with him... not only do I find it completely pointless communicating with him (unless I totally can't help myself) but I think he totally believes what he says...

Flat earthers are morons... its just a fact... like, educated flat earther is an oxymoron... haha!!

See what I did there?
