AMS-Flight Carat are mounted on the upper surfaces of the inner panels, with turbulators on the underside to ensure a controlled boundary layer transition from laminar to turbulent flow without separation. The wings have 3° of dihedral. Though the Discus and the Carat share wings, they position them differently: the Discus is a mid-wing aircraft, the Carat a low-wing one. Like the Discus, the Carat has a high T-tail with separate tailplane and elevators. The tailplane, like the wings, is detachable for easy transport. The cockpit, enclosed in a large clear single piece canopy, is at the trailing edge of the wing,
