dude rivenator, you can't fly out the atmosphere with a plane

its not very tough mental gymnastics

I tried akhan, but he just refuse everything we throw at him

now, imagine the globe earth and your airplane, it wouldn't make sense if u fly straight and don't gain altitude

if you understood anything about physics, you wouldn't be asking this absurd question

@Akhanyatin therefore, the earth is not a globe

riven: to fly, you need lift, produced by the plane wings, at high altitude, the air is thin, produce no lift, you fall.

how do you define straight line?

perpendicular to the ground?

it was a fun conversation, i just want u to think about it.

parralel to the ground

yeah my bad parallel

he's going to leave thinking he won an argument, funny.

u have a cesna and cant even answer my question lol

so you're saying, if you're on a sphere, and keep parallel to that sphere, you're going to somehow distance yourself from that sphere?

draw a circle on a piece of paper, then draw a larger circle but with the same center

that should answer your question

yes, its logical isn't it? u have a plane on a sphere flying parallel to the ground, if it flies in a straight path it would gain altitude if its a globe earth @Akhanyatin

tell me where the logic is flawed

just draw a circle on paint or wtv and then draw a larger circle from the same center

yeah and?

do the circles ever meet or diverge?

the plane fly straight

a plane can't fly straight out of the atmosphere because that would be the equivalent of just flying upward

what the fuck does the circle have to do with anything, this isn't hard to imagine

no ull hit max plane altitude and the airplane will have not enogh lift, too much drag, and start loosing altitude, its not a good argument riven, if the air around earth was thick enough even at high altitude that could be a debate, but its not.

but if you drew a line from a certain point, and continued straight, yeah you'd pop out of the atmosphere

@Akhanyatin so you would gain altitude correct?

you'd distance yourself from the ground

now tell skywalk who has a cesna, does he gain altitude when he flies straight?

If I'm flying parallel to the ground and I never adjust my attitude, shouldn't my altitude above the ground start rising if the Earth is curving away from me?

This question, and most of the responses and comments to it, are based on a misunderstanding of what "straight and level flight" means. It does not mean flying in a Euclidean straight line at a constant speed. The concept of flying a Euclidean straight line doesn't make any sense when it comes to an aircraft flying through the atmosphere of a more or less spherical planet. "Straight and level" instead means flying with zero bank, zero roll, and a constant speed, constant altitude, and constant pitch angle.

Damn nice, im truly talking with kids

cant even argument

lol a plane relies on instruments to stay level

First if the turbines work worse as air rarifies at high altitudes, and at some point lose "traction" and fall. Secondly, the levitating force on the wings depends on the air density and the plane relative speed to the air, so even if the "traction" effect is low, the air support will be lower and at some point will not be sustained. Thirdly, as it escapes horizontally the angle of vertical becomes that of the flight direction, or as was mentioned, it will behave as if you suddenly start flying up, which will eliminate air support on the wings and fall.

how do you think these instruments work?

the guy probably never even saw a plane and he's arguing that they should fly out the atmosphere

beyond reason

then he say things like, we are kids, and cant argument, pointless

From his post:
I am a student pilot. I've got 100 hours and 300 landings.

Throw a paper airplane. Does it fly in a straight line? Of course not. Neither does a big plane.

It only follows the course, horizontally and vertically, that the pilot controls it to fly. The way it turns from one heading to another is by temporarily banking to one side, exactly like a bicycle. The way it changes altitude above the ground is by using more or less power. The way it changes speed is by using more or less elevator trim.

All of these things are monitored by the pilot and adjusted as needed. If they are not adjusted, the plane flies at a constant speed, on a constant heading, at a constant rate of climb or descent above the earth.

Take a flying lesson. It doesn't cost much and is a great experience.
