Why do most biplanes have their top wing slightly forward of the lower wing? The wing includes a longitudinal keel of lightweight tubular construction, leading edge members and a cross brace. Also the air density and wing area are usually fixed, (assuming you arent approaching Mach 1 or extending flaps), which conveniently leaves us with a direct relationship between airspeed and CL: At high airspeeds a lot of air is passing the wing so the CL must be low the wing only needs to divert the passing air a small amount to produce the lift required to hold the plane up. Its state-of-art 250 DS engine is backed by thousands of hours of reliable service over several decades, providing pilots with stress-free operations.
