Smooth Flying

I have been enjoying the B747-400 lately. But I still find myself in a very shaky flight. Most of the flights I fly do not have wind, is there any way to improve my skill in this?

It’s the floating point bug. It makes your aircraft shake.

Can you somehow describe this bug to me? I don’t really understand it.

It happens when you get too far from your origin airport(airport you takeoff from) I don’t really understand it put the information I put is what I know. :)

It’s the algorithm issue, they’ll fix it in future. By right now it’s ok just fly like normal, nothing much issue right now.

Happy landing!

The floating point bug happens when you fly a long distance.
It’s due to the way we store the location of the plane. We store it in a 32bit (signed) floating point.

To simplify: floating point means that the numbers left to the decimal point are sharing the 32bits of storage with the numbers to the right of the decimal point.(floating point -> the point moves right or left depending on where the space is needed)
The bright side is that it allows us to store very small numbers when we need precision, and very big number when precision don’t matter.
But that also means that the more space you take on the left side (the bigger the number is) the less precision you have (less space for the right side).
And that’s what’s happening in infinite flight. The numbers gets so big when you fly accross a region, that the precision gets really bad and makes your plane move like if it is moving on saw teeth.

Aliasing/Anti aliasing is due to the way the graphics are rendered and it’s a separate issue from the floating point bug.
