As we saw in the shows, shuttles landed by use of anti-grav and thrusters. In Star Fleet Battles they are listed as Power Landing, they're a form of VTOL. These are SFB ships capable of safe landings and takeoff.
Another form of this, usable with actual starships, as a powered takeoff and landing, is the Gravity Landing System and needs an actual tractor beam (set to repulse). In ACTASF terms the Orion Destroyer and the Tholian Corvette and Destoryer can use this.
The Romulan Battle Hawk, Snipe, War Eagle and King Eagle configuations can land and take off aerodynamically. Everything else crash lands with some, like the Federation saucer sections, having a chance to have some survivors.
"@Reynard They mean that space is in fact 3d, so you can fly over the planet template to represent orbiting it along the Z axis. This is a pretty common rule in space games."
You know what? Simple rules, I'll go with it.
