Hey.
We had an issue with flyers when we were playing, and figured someone here might have an answer.
Would a flyer with no ground movement be able to land? And if it did land would it be able to move up again freely with it's air movement or would it have to dedicate an action to lifting from the ground?
No the flyer couldnīt land in the manner of speaking getting from airborne to earthbound.
But you could just fly at 0,001 inch height... if your group allows that
As I see it you would have to choose a height band/altitude in full inches (Iīm not sure if the altitude of "0 inches" would be possible, I think not, since that would make an earthbound movement senseless).
If you could land I think you would not need an action to change the status to airborne again.
You are allowed to change the altitude up to the airborne movement, so you would just declare that I think.
Banshees do that all the time... Hopping from airborn to earthbound ;-)
