NightAngel151SakashiroBtw, is there an explanation in the lore for why ships heat up so much when they fly across a planet surface upside down?
No idea if there is an actual lore explanation but here's what I assume based on basic physics:
The ships in game are space ships and do not have aerodynamic lifting bodies or wings and right now the planets we can land on / fly close to the surface of don't have an atmosphere to facilitate aerodynamic lift anyway. Basically, when flying close to a planet's surface your ship's ventral and dorsal thrusters (depending if you're upside down/right side up) are what is keeping you from falling out of the sky. Therefore, your ship heats up more than it normally would because those thrusters have to burn constantly until you either land or point straight up so your main drives can do all the work..
Yep. Your ship has limited capability to remove heat from itself so the more work the thrusters have to do the faster heat builds up. Same for turning sharply upward, especially when charging up the FSD at the same time. The thrusters underneath your ship do seem to have an easier time than the ones on top while near a planet surface however, even though in space they seem to perform about the same.
