Atmosphere (R204F)

A planet’s atmosphere is rated as “good,” “bad” or “no” air. Regardless of planet atmosphere, land areas with white letters
as their title all have good air (on bad or no air planets, they have domes or force screens). In bad or no air (black labeled
areas on planets of that type) you need life support to survive (R213). In bad air, normal skimmers will not function — their
air-breathing engines automatically and instantly break down. A skimmer purchased on a bad air world will work on that
world (due to special engine modifications), but won’t work on any other bad air world, nor on a world with good air. No
skimmer can function in “no air.” No air also prevents starships and ship’s boat from making a powerless glide landing;
instead, a powered landing is needed (which uses fuel).
