Title: gravity
Post by: Killer91 on September 02, 2011, 06:49:49 PM
Been a long day at work and I was thinking about plane weights and the obvious effects gravity has on it. We all know that at sea level gravity exerts a force of 9.8 meters/second2. I
But as altitude increases gravity obviously exerts less force. I can't remember how fast it decreases but it wouldn't make a huge difference in the weight of a plane but I was wondering if this is modeled into the game?

I seriously doubt, it does effect real airplanes much.

Gravity at 30,000 ft is 0.28% less.  I assume it is not modeled because it is essentially negligible.

And would affect all planes proportionally anyway.

Just did comparison test.

Real at 32,808.39ft alt and at 34.0522222 degrees lat -> 9.77594m/s2
TA arena at same alt, latitude of approx 1 degree -> 9.806647m/s2

So yeah I agree, doesn't seem to be modeled.

Just keep this in mind, gravity pushes not pull.

Only AKAK and Chalenge can tell us with any authority whether or not gravity is modeled accurately at 70k.

Gravity is merely the manifestation of mass on the space-time continuum. Although it is an illusion, the consequences of being caught in it's force are very real.   :joystick:

Perhaps the consequences of being caught in its force to such an extent that we "die" is merely the passing of our "self" from one continuum to another.  We are "dead" in this one and are "born" in a different one... Maybe perhaps, perhaps maybe....

That would make those that die as a result of gravity very lucky, since they get to "perpetuate", whereas the others who die of non-gravity related causes just cease to exist.  Perhaps this is why we all aspire to be pilots.  Perhaps it is the intrinsic hope that we will all die from gravity and therefore perpetuate.  Maybe perhaps, perhaps maybe...

I don't believe that is the case...just in case someone wants to crucify me for making up something new like they did to that other dude...

Tell you what climb up to 70,000 feet in RL jump out of the plane and if you survive attempt the same in AH and we will know  :devil

Col. Joseph Kittinger did it, 76,400 feet. Also the first man (and only as far as I know) to break the sound barrier with his body.

^ he Did not break the sound barrier.

Regardless if gravity is modeled at all, at 70k in AH the only aircraft capable for us is the me163, which although fun for S's and G's has nothing do do with the game at all.  Put a wishlist up asking for airspace to be modeled correctly at that altitude and see where that gets you  :lol

it doesn't make that much difference, as others have pointed out.. even in low earth orbit, it's still about 9m/s2

Well, the answer to the original question is that it makes almost zero difference.  Whether it's modeled or not does not really matter.

Yep you guys answered that one pretty quickly. Thanks for the answer! I was thinking it dropped off a little faster than that but that physics class was 3 years ago lol  :old:

Just keep this in mind, gravity pushes not pull.

This is only half correct concerning the particles of pair-production, particular matter particles will accelerate in the direction of the gravity field while the corresponding antimatter particles will accelerate away from it.

1st jump was from 76k but the big jump was from 102k.

Your right, I think I forgot some of the specifics.

From all of the articles I have read, he did momentarily break the sound barrier.

It won't make much of a difference BUT, since you asked, the formula for force due to gravity is the inverse square of the distance.

(http://upload.wikimedia.org/math/0/f/3/0f36df929ac9d711a8ba8c5658c3bfee.png)

F= Force due to gravity
G=Gravitational constant
m1= Mass of body 1
m2= Mass of body 2
r= radius from center of mass of body 1 to center of mass for body 2

As the radius (r) increases the force is affected by the square. So, simply put, you double the distance you get a forth of the gravity. A plane flying at 30,000 feet only increases that radius by about .1% over sea level. Such a tiny difference when compared to the gigantic numbers involved.

Not sure if it's still the same or not but at 98K in a 163 the plane would just disappear on you.  You'de still be there but no more plane.

I can't tell you about high alts but gravity is very effective down low...... I know this from experience.


I would post film but they always burn in the ensuing fire.

Gravity is never constant.

It changes density every day.

Which would explain why its harder to get out of bed on some days.

It seems to get denser every year. :old:
