MSFS2024
Some jet aircraft can climb to very high altitudes. What I noticed is that the code prevents stars from being displayed whenever the aircraft is above the day side of the Earth, regardless of how dark the sky actually is.
This is not realistic. I suggest modifying the code so that the visibility of stars is determined not by the aircraft’s position, but by the shade of blue or overall brightness of the sky. In real life, stars are visible at extreme altitudes even during daytime.
