I'm not really sure about that, as the drive specifies use only in a planetary magnetic field. Really the only difference between the Air and Space profiles is that Air profiles calculate an air speed.

No, but you can check the "Don't Filter systems by TL" checkbox at the top, add a Reactionless Drive, then go to the System Options section and set the drive's TL to make it mimic any of the standard TL's.
