The downside of this design is that the low-speed flight feature will be affected, because the smaller wing type requires a larger air flow to create enough lift to continue flying. Cow American Flag Jungle Sunshine Canvas. To overcome this problem, the Bf 109 included advanced wing reinforcement devices, including automatic wing edges that spread out on the front edge, and large convex caps on the rear wing edge. It also includes flaps that will spread out when the flaps are lowered, thereby increasing the area of the flap area once they are exposed. When used, these devices effectively increase the lift factor, making them feature better cruising at low speeds and large angles of attack. Another drawback of large wing pressure is that the fighter will require more motivation to maneuver. Given the limited capacity of existing engines, it means that the Bf 109 is not as narrow as other designs with larger wings. Lifting devices can compensate somewhat for this problem, but they also increase drag and make the aircraft slower correspondingly. Given that mobility is the last priority in the features that RLM wants, Messerschmitt believes that the advantages are more significant than the defects that must be present.
