I’m currently building and testing a solar plane and I figured out something I think is weird:
While flying in the same way as Droo’s rotation I can achieve a max altitude of 48’000 meters at a surface speed of 280 m/s, but while flying against Droo’s rotation with exactly the same settings the plane keeps an altitude between 34’000 and 36’000 meters at a speed of ~140m/s.
I fully understand this phenomenon with rockets because they benefit of the rotation speed of the planet but I don’t really get the reason why it applies to my plane as its speed is relative to the surface. The only answer I can imagine is that the air isn’t static and that there’s a constant wind in the same direction as the rotation of Droo but I’m pretty sure there’s no wind right? Has someone a hypothesis or an explanation?
I don't think there is wind because propellers don't windmill and floppy rotators with wings on it will point away from the wind if it exists.
Maybe you are flying too high and the game thinks you are a rocket?
