An apron for parking and dealing with aircraft comprises a hardened, reinforced support layer (1) and an additional covering layer (2) which is arranged on the said support layer. Conduits, channels, tunnels or pits may be arranged within the thickness of the covering layer in order to supply fuel, electric current, drinking water, compressed air, preconditioned air or oxygen and other facilities and to discharge rainwater and waste liquid. Moreover, folding platforms, telescopically extendable pylons, a fuel-feed robot, a conveyor belt for loose baggage and the like may be accommodated in the covering layer.
