Airplane Flying in One Direction

How can you explain that an airplane can takeoff from, let's just say for argument's sake, any city located on the Equator and fly due east.  If it never changes it's course and is refueled in flight it will eventually arrive in that same city.  How can that happen if the world is not round?

Depends on what your definition of "never changes it's [sic] course" and "due east" are.

On a globe, the situation you describe has the airplane flying in a circle before returning to its origin.

The flat earth is round as in this map:And flying continually east means flying with North exactly on your port side all the time so that path would be the Equator, the solid black line on that map.
The curve is quite imperceptible and only amounts to one minute of arc for each Nautical mile flown and would be quite imperceptible.
And no plane could fly that distance by dead reckoning alone as you are suggesting.  Some position fixes would be needed.
Look at the compass as used in many smaller aircraft:It couldn't be read to 1° and that does not allow for the compass errors. These are calibrated for but only specified each 30° as in:
Those errors also depend on the electrical equipment in use.

In other words, the plane could fly due east around a 5400 Nm radius circle on the flat earth map (the equator) and land back where they started.

BUT: Try circumnavigating the flat earth in a North-South direction.
That circumnavigation has been don on the Globe a number of times though not in a straight line as aircraft have to re-fuel.

Airplane needs to go curved when the pilot would direct the airplane either "eastwards" or "westwards".

Globe map is wrong.

I see no proof that the "Globe map is wrong".
And would you please explain how the earth can be circumnavigated from north to the south pole then north to the north pole and back.

That has been done a number of times and here is the first:

The expedition including "Sir Ranulph Fiennes and Charles Burton (both UK) of the British Trans-Globe Expedition" is credited with being the first to circumnavigate both geographic poles. First circumnavigation via both Poles, surface
A better description is in Transglobe expedition: Ranulph Fiennes ‘Vertical’ Circumpolar Navigation of the World


How could that be done on either your map or the usual "Ice-Wall" map?

In any Euclidean space, that is impossible, regardless of the shape of Earth.
It ultimately comes down to how you are determining the course.

For a RE, the plane pitches down to follow the curve of Earth, turning in a circle with an axis perpendicular to the direction of flight and parallel to Earth's surface.

For the common FE map, the plane turns left, following a due-east path, turning in a circle with an axis perpendicular to the direction of flight and Earth's surface.

Globe map is wrong.

Prove it or stop making such a nonsensical claim.

Flight: Gronigen to Bremen >> 151 km in 41 minutes.
An airplane with 151km/(41/60) hour = 220.9 kph. So motogp beats an airplane's speed.
Are you kidding??

And just like the ones you've posted in the past, there is time for taxi, takeoff and landing. Plus with such a short distance they likely never get up to cruising altitude and full speed.  Why do you keep ignoring this?

You are Brilliant!
I remember the last time I looked out of my window in Gronigen (sic) and decided to go to Bremen, only to find I was already in my leathers with 46 on my lid, and my crew had the M1 fired up with the tyres warm and a surprising amount of fuel on. For some reason I could do race average with lights and traffic and all.
Still took an hour.
Bugger!

I did.

It is excellent evidence for a globe earth. Notice how the map tracker in the upper right corner shows a curved path while the plane is flying in a straight line?

I suggest you remove that video from your signature if you’d like to be taken seriously by your Phew phwiends

Airplanes generally do not cruise by compass, but using an inertial system (INS). Inertial systems (gyroscopes) have the advantage that are less sensitive to magnetic anomalies, compared to compasses. They also indicate geographic north, and not magnetic north, which is less useful.
Because airplanes fly on a round and rotating Earth, the gyros of the INS need to be realigned periodically. With older airplanes, the pilot needed to intervene every -say- 15 minutes to realign the gyro manually. With modern airplanes, this realignment is performed automatically.
In a flat and non rotating Earth, the gyro of your airplane would not change direction and would not need to be realigned. It would continue to track the original course.

In a round and rotating Earth, the gyro shows two types of movement: the drift rate and the transport wander.
The drift rate is the effect of Earth rotation, and it would obviously be visible even with a stationary airplane. The transport wander is the effect of changing the Earth parallel, ie moving closer or far away to/from one of the two poles.
In two words, changing longitude generates the drift, while changing latitude generates the wander. In any case, after a while, the gyro in the airplane is automatically realigned in the IN system.

In my view, the gyro proof is just the smarter version of the Foucault pendulum: and this is the stronger proof of a rotating round Earth, observable by anyone and therefore totally independent from any fakes.

clear that you have no idea what you're talking about and ignore all criticisms.

Showing it isn't a commercial flight.

I know this is hard for you to understand with you repeatedly failing to grasp it.
Planes don't magically start at cruising speed right from the gate, nor do they magically stop instantly.

If you want to get an idea of how fast planes can fly you will need a long flight.

If you mean clear that you are a troll, sure.

Do you have any evidence of anyone doing this and the complications actually involved. With out going out of my way, the only person i heard was Amelia Earhart and she never came back... just my 2 cents.

The first "cross-equator circumnavigation" by air, though not along the equator was by Kingsford Smith and his crew.

Cross-equator flight
After completing the first trans-Pacific crossing on 9 June 1928, flying from Oakland, California to Brisbane, Australia, Charles Kingsford Smith and Charles Ulm spent several months making other long-distance flights across Australia and to New Zealand. They decided to use their trans-Pacific flight as the first leg of a globe-circling flight.
They flew the Southern Cross to England in June 1929, then across the Atlantic and North America, returning to Oakland where their trans-Pacific flight had begun.

This next (long bit) is off-topic in that neither circumnavigations were by air but Mike Horn's was close to the equator.

But rather than Kickass Trips they should be called You've Gotta be Mad Trips!
I mentioned Ranulph Fiennes before but I put in more here because of the link to Mike Horn and his solo and human-powered circumnavigation of the globe following the Equator at Latitude zero.

Transglobe expedition: Ranulph Fiennes ‘Vertical’ Circumpolar Navigation of the World at the 0° Greenwich Meridian

In 1979, adventurers Sir Ranulph Fiennes and Charles R. Burton set out to make the world’s first circumpolar navigation, traveling the world “vertically” traversing both the North and South Pole while using only surface transport. Starting from Greenwich in September 1979 in the United Kingdom, they went south, arriving at the South Pole on December 17, 1980. Over the next 14 months, they went north again, reaching the North Pole on April 11, 1982. Travelling south once more, they arrived again in Greenwich on August 29, 1982 almost three years after their departure.

Years later this ‘Vertical’ circumnavigation at Longtitude zero would inspire Mike Horn for his solo and human-powered ‘Horizontal’ crossing of the globe following the Equator at Latitude zero.

On their expedition Fiennes’ team managed to achieve an impressive number of world’s firsts among them being:

• Bothie, their dog, was the first dog to visit both poles.
• Ginny Fiennes was the first woman to join the Antarctic Club and to receive the Polar Medal
• And they played the first ever game of cricket on the geographical South Pole

For the rest, with route and photos: Transglobe expedition: Ranulph Fiennes ‘Vertical’ Circumpolar Navigation of the World at the 0° Greenwich Meridian

This is the route Mike Horn took for his solo and human-powered ‘Horizontal’ crossing of the globe following the Equator at Latitude zero:

“When I left, I thought I knew enough to go round the world this way. Now that I am back, I know that I don’t know enough to start again.”

When I read this sort of thing I honestly don't know what to think of people that still the earth can be flat. Are all these people lying?

Yeah but if you believe it's flat, i think Amelia Earhart's story might be worth exploring because i heard a seasoned writer quote it as a proof. I don't know the whole story, but it looked like it was only globellievers responding.

This was in the low tech 50's, but even then, apparently she was using some new military torroid compass.

This was in the low tech 50's,

It wasn't "the low tech 50's", it was the lower tech 30s:

Amelia Earhart - HISTORY
During a flight to circumnavigate the globe, Earhart disappeared somewhere over the Pacific in July 1937. Her plane wreckage was never found, and she was officially declared lost at sea. Her disappearance remains one of the greatest unsolved mysteries of the twentieth century.

but even then, apparently she was using some new military torroid compass.

And it was not some "new military torroid compass" but what later became known as the "Automatic Direction Finder or ADF" sold by the Bendix Aviation Corporation, no great military secret.

Hooven’s 1966 letter to Fred Goerner quite clear: Removal of his radio compass doomed Earhart
Frederick J. Hooven, famed for his engineering inventions, was born in Dayton, Ohio in 1905, met Orville Wright as a child and by age 15 was a regular visitor to the Wrights’ Dayton laboratory. After graduating  from MIT in 1927, Hooven was hired by General Motors, and rose to vice president and chief engineer of the Radio Products Division of Bendix Aviation Corporation by 1935.  His Hooven Radio Compass, which he  later sold to the Bendix Company, is now known as the Automatic Direction Finder or ADF, was installed in Amelia Earhart’s Electra in 1936, but was later replaced by an earlier, lighter unit.

The modern instrument would have given her a heading on the transmitter of the cutter Itasca at Howland Island even under poor reception condi­tions and it would have shown her without ambiguity that her destination was still ahead.

The modern direction finder that I invented in 1935 had some important points of superiority over the old simple null-type that had been used ever since before 1920.

Have a look at this article on the ADF: Radio direction finder. While they were important during the war I doubt any were classified in 1937.

I imagine that Amelia Earhart removed the newer unit to allow more fuel to be carried. On the first circumnavigation flight the aircraft didn't even carry parachutes or life-vests because of weight issues.

But why is it of special interest to flat-Earthers? There seem to be no flat/Globe issues.

The idea is that the map between Hawaii and North America is incorrect, i believe. And i was probably incorrect to call it a "torroid" compass.

But Amelia Earhart did not disappear "between Hawaii and North America" but on the leg from Lae, PNG, to Howland Island in the Pacific.
Wikipedia has tremendous detail including 286 references, a massive bibliography, links to many videos and:

THIS DAY IN HISTORY JULY 02 1937, Amelia Earhart disappears
On July 2, 1937, the Lockheed aircraft carrying American aviator Amelia Earhart and navigator Frederick Noonan is reported missing near Howland Island in the Pacific. The pair were attempting to fly around the world when they lost their bearings during the most challenging leg of the global journey: Lae, New Guinea, to Howland Island, a tiny island 2,227 nautical miles away, in the center of the Pacific Ocean. The U.S. Coast Guard cutter Itasca was in sporadic radio contact with Earhart as she approached Howland Island and received messages that she was lost and running low on fuel. Soon after, she probably tried to ditch the Lockheed in the ocean. No trace of Earhart or Noonan was ever found.

And i was probably incorrect to call it a "torroid" compass.

Calling a "compass" is understandable because Hooven originally called it a ""Radio Compass" and, I guess that the loop radio antenna on her Lockheed Model 10-E Electra looked like a "toroid".

Wikipedia says this on the Hooven Radio Compass:

A separate automatic radio direction finder receiver, a prototype Hooven Radio Compass, had been installed in the plane in October 1936, but that receiver was removed before the flight to save weight. The Hooven Radio Compass was replaced with a Bendix coupling unit that allowed a conventional loop antenna to be attached to an existing receiver (i.e., the Western Electric 20B). The loop antenna is visible above the cockpit on Earhart's plane.

The Hooven Radio Compass was later renamed the Bendix ADF.
It would have been far easier to use and probably had better range and accuracy but "was removed before the flight to save weight".
