Forces in equilibrium when on ground?

Hi all,

I know this is a very basic question and more than likely one of definition/terminology, but I've come across it a good few times now. It was a question in one of the theory exams as well.

Are the four forces acting on an aircraft on the ground (stationary) in equilibrium?

I would've said no, assuming we are talking about lift/weight. Since (at least in zero wind conditions) the wings are not generating lift, what's the name of the force opposing weight in this scenario?
