Popular military transport aircraft, such as the Airbus A400M or the Boeing C-17, are typically engineered with high-wing designs.

Aircraft wings are typically attached to the fuselage in one of two primary configurations: positioned above the fuselage or below the mid-point of the fuselage. While commercial aircraft commonly feature low wings for practical reasons, military transport aircraft frequently incorporate high-wing designs.
The difference between low-wing and high-wing designs
In terms of functionality, both low-wing and high-wing aircraft share similarities, as their primary purpose is to generate lift while in motion through the air. Nonetheless, notable distinctions exist between the two configurations.
Low wings are strategically positioned just below the midpoint of the fuselage, and this placement holds significant importance. The wing structure comprises a central wing box that integrates with this fuselage location, attached between the passenger cabin and the cargo hold.
This positioning ensures minimal interference with the passenger cabin while also serving as a space for certain landing gear components within the wings and wing box. Low wings are also more aerodynamic and facilitate easier access to the engines for maintenance and inspection during airport turnarounds.
Meanwhile, high wings are above the mid-point of the fuselage, and they are usually flatter, giving more ground clearance. This configuration enables safer operations over uneven terrain. However, the significance of the wing structure extends beyond that, as it facilitates unobstructed access to the fuselage, enabling efficient transportation of cargo.
