ABSTRACT:
A combination airport air and ground transportation marker and airport traffic way comprises broad, substantially coextensive first and second sheets of pliant material each having a perimeter edge formed with a fluid ballast bladder formed with a fluid inlet for permitting intake and outtake of fluid relative to the bladder for filling and relieving the bladder, and a relief vent for relieving pressure in the bladder during the filling of the bladder with fluid and the relieving of the bladder of fluid. The first sheet is splayed out onto an airport traffic way, and the second sheet is splayed out onto the airport traffic way overlying the first sheet of pliant material, whereby the first and second sheets cooperate forming a marker for the airport traffic way. A charge of fluid fills each of the bladders fluid ballasting the marker relative to the airport traffic way.
