A "mid-wing" design refers to the placement of an aircraft's wings at a position that is approximately halfway up the fuselage. This configuration helps to balance the aircraft's weight and improve stability during flight. Mid-wing designs are commonly found in various types of aircraft, including commercial airliners and military jets. One advantage of the mid-wing layout is that it allows for a more efficient aerodynamic profile. By positioning the wings higher, the aircraft can achieve better lift-to-drag ratios, which enhances fuel efficiency. This design is often associated with modern aircraft like the Boeing 737 and F-16 Fighting Falcon.
