Eric knows the earth isn’t flat. That’s why he declined the chance of a life time: To see the 24 hour sun in Antarctica. Something few people get the chance to experience.
Flight Dynamics Summary 1. Introduction In this summary we examine the flight dynamics of aircraft. But before we do that, we must examine some basic ideas necessary to explore the secrets of flight dynamics. 1.1 Basic concepts 1.1.1 Controlling an airplane To control an aircraft, control surfaces are generally used. Examples are elevators, flaps and spoilers. When dealing with control surfaces, we can make a distinction between primary and secondary flight control surfaces. When primary control surfaces fail, the whole aircraft becomes uncontrollable. (Examples are elevators, ailerons and rudders.) However, when secondary control surfaces fail, the aircraft is just a bit harder to control. (Examples are flaps and trim tabs.) The whole system that is necessary to control the aircraft is called the control system. When a control system provides direct feedback to the pilot, it is called a reversible system. (For example, when using a mechanical control system, the pilot feels forces on his stick.) If there is no direct feedback, then we have an irreversible system. (An example is a fly-by-wire system.) 1.1.2 Making assumptions In this summary, we want to describe the flight dynamics with equations. This is, however, very difficult.

(No Coriolis accelerations and such are present.) • The aircraft has constant mass. • The aircraft is a rigid body. • The aircraft is symmetric. • There are no rotating masses, like turbines. (Gyroscopic effects can be ignored.) • There is constant wind. (So we ignore turbulence and gusts.) 1.2 Reference frames 1.2.1 Reference frame types To describe the position and behavior of an aircraft, we need a reference frame (RF).

Objectively wrong. Appears flat and appears to be motionless. Moves too slow for you to feel acceleration or deceleration. 24 hours for a full rotation. Curve is too gradual for you to see with your eyes. Can't see Alaska from my house in mainland America even in an airplane far above any refraction.
Every sunset disproves a flat Earth. That the sun vanishes from the bottom up is impossible on a flat Earth with the sun circling above it. So it's a simply experience that the Earth is not flat. And basic physics tells you that one can't experience a motion with a constant velocity, and one can experience an accelerated motion only if the acceleration is great enough. So your "experience" of "motionless" proves exactly nothing.

Eric is a liar, and convinces stupid people to believe he is right.
FLAT to Flat Earthers means. F.undemental L.ack A.ny T.hought
5:45 woah woah woah , let’s get this straight. Your expecting Eric to do outside, touch some grass, and observe the real world??? Don’t be daft!! 🤣
Why do we pay so much attention to flat earthers?
You guys coming outta woodwork 🤔
Flight Dynamics Summary
1. Introduction
In this summary we examine the flight dynamics of aircraft. But before we do that, we must examine some basic ideas necessary to explore the secrets of flight dynamics.
1.1 Basic concepts
1.1.1 Controlling an airplane
To control an aircraft, control surfaces are generally used. Examples are elevators, flaps and spoilers. When dealing with control surfaces, we can make a distinction between primary and secondary flight control surfaces. When primary control surfaces fail, the whole aircraft becomes uncontrollable. (Examples are elevators, ailerons and rudders.) However, when secondary control surfaces fail, the aircraft is just a bit harder to control. (Examples are flaps and trim tabs.)
The whole system that is necessary to control the aircraft is called the control system. When a control system provides direct feedback to the pilot, it is called a reversible system. (For example, when using a mechanical control system, the pilot feels forces on his stick.) If there is no direct feedback, then we have an irreversible system. (An example is a fly-by-wire system.)
1.1.2 Making assumptions
In this summary, we want to describe the flight dynamics with equations. This is, however, very difficult. To simplify it a bit, we have to make some simplifying assumptions. We assume that . . .
• There is a flat Earth. (The Earth’s curvature is zero.)
• There is a non-rotating Earth. (No Coriolis accelerations and such are present.)
• The aircraft has constant mass.
• The aircraft is a rigid body.
• The aircraft is symmetric.
• There are no rotating masses, like turbines. (Gyroscopic effects can be ignored.)
• There is constant wind. (So we ignore turbulence and gusts.)
1.2 Reference frames 1.2.1 Reference frame types
To describe the position and behavior of an aircraft, we need a reference frame (RF).
"...we have to make some simplifying assumptions. We assume that . . ."
The words 'assumption' and 'assume' do, in fact, have several meanings. In this, and many other manuals, assume means to pretend, make believe, or simulate.
Also, this implies that one must already know something, such as the Earth is spherical, in order to pretend that it isn't for simplifying this flight dynamics summery.
Nice deflection and cherry picking bro.
@ Oh the they assume is flat but flight the plane like is spherical? Ok got it.
🤣😂 And by the way NASA has the same summary without “assumptions”…
@ Yeah, show me a picture of people living upside down in Australia… 🤡
@ Yeah, show me a picture of people living upside down in Australia… 🤡
Soo the world is flat or round?...
Earth is a sphere. 24 hour sun in Antarctica can't be explained on a Flat Earth.
10:40 it is a waste to give Dubay exposure.
If there were foot prints, he makes the opposite argument. He is just too dishonest, and flat earth is his way of life.
There has to be foot print don't be a dumb ass
Flat and motionless. Simple experience simple fact
Objectively wrong. Appears flat and appears to be motionless. Moves too slow for you to feel acceleration or deceleration. 24 hours for a full rotation. Curve is too gradual for you to see with your eyes. Can't see Alaska from my house in mainland America even in an airplane far above any refraction.
You’re Objectively wrong and that’s incredibly easy to prove.
that' s for simpletons.
But observing the sun's motions belies your belief.
Every sunset disproves a flat Earth. That the sun vanishes from the bottom up is impossible on a flat Earth with the sun circling above it. So it's a simply experience that the Earth is not flat.
And basic physics tells you that one can't experience a motion with a constant velocity, and one can experience an accelerated motion only if the acceleration is great enough. So your "experience" of "motionless" proves exactly nothing.
