From Rise: The Vieneo Province - The Space Simulator MMO from Unistellar Industries, LLC
Currently we have two (2) types of controlled airspace in the game.
Deois has what is very similar to an Enhanced Class B airspace (37km laterally and 5.5km vertically) with a procedural area (where the menus start appearing) at 55.5km and 18.25km respectively.
Speed limit is 125 m/s IAS. Air Traffic Control cannot clear you to go faster.
Controllers run 14 hour shifts alternating every other day.
The docks have what is similar to a Class C airspace except that it is a sphere around the facility with a 20km procedural zone and a 18.5km perimeter.
