Saab 340A altitude record

If anyone wants to start discussing how accurate the flight model is I strongly suggest that you do most of your analysis in the intended flight regimes.

 

Tweaking the airframe drag or engine power system so that you cant exceed a given altitude is not going to be a difficult patch.

 

Enjoy your 1.0 altitude record while it lasts.

Hi, guys!

Here is the screenshots of the sky color varies with altitude in x-plane. The left photo shows what the sky look like when on the ground, and the right photo shows what the sky look like when at the altitude of 37,800 feet MSL which the sky looks dark blue. Do notice the atmosphere halo is much bigger when on the ground on the left photo than the atmosphere halo at 37,800 feet MSL on the right photo? Please see attached. Thanks!

Cheers,

Vincent

The halo looks larger in the left photo. Also this effect is very realistic.

Hi, dwayne299!

You got that right this effect is very realistic! The higher up you go, the smaller the halo will look! Question for you, on the right photo which have a smaller halo at 37,800 feet MSL, is there a slight curvature of the earth's horizon? Thanks!

Cheers,

Vincent

Hi, dwayne299!

I asked info@x-plane.com to see if I can see the curvature of the earth at 15,000-20,000 feet and they said sure. I'd to be quite higher than 15,000-20,000 feet say about 200,000 feet. I understand that you can see the curvature of the earth from the concorde or the SR-71 Blackbird airplanes.

Cheers,

Vincent
