IMTU, I usually rule that any streamlined or partially streamlined ship's hull has lifters built into it that can nullify gravity to an extent. (Essentially a bank of Air/Raft lift modules in the hull.) They float up to a safe altitude and then engage their m-drive to pick up speed for either an orbit or transit to jump radius. Streamlining comes in handy when making any Piloting rolls, though I reserve those for special cases. The lifters are also used when repositioning the ship on the landing pad - energize the grid, and let local "tugs" or ground based tractors float the ship around. This gets rid of the need for wheels.
