The wings of a 737 are lower to the ground than its counterpart the A320. While some bag tugs can move under the wing of an A320, this is not possible with a 737. While you may not need to complete a full simulation for every aircraft at a gate, the representative critical aircraft may suffice (usually the largest aircraft for a certain Code/ADG).If you take a cross-section view, the upper surface is curved and the lower surface is flat, creating an airfoil like that of an airplane wing. As the bird moves forward, the curved upper surface causes the air to flow faster over the top of the wing, creating lift. So even when the bird glides or soars, the wing shape helps keep it up in the air.

In areas where buildings create strong gusts of wind or drafts along streets, pigeons have learned to spread out their wings and "surf" these air currents in order to travel faster and more easily through city landscapes. Four reasons why birds spread their wings: 1) Regulating body temperature. 2) Stretching muscles.(See Figure I at the end of this section). (B) THE WINGS Amazingly, the bird's wing physically compares to the human hand and arm which is displayed at the end of this section in Figure 2.

Structure and Function.The wings have additional hinged, rear sections near the body that are called flaps. Flaps are deployed downward on takeoff and landing to increase the amount of force produced by the wing. On some aircraft, the front part of the wing will also deflect. Slats are used at takeoff and landing to produce additional force. The spoilers are also ...

The primary role of a bird's beak is collecting and ingesting food. It has evolved into a wonderful variety of forms, each adapted to a particular diet or foraging technique. Birds can use their beaks to process their food to some degree (e.g., removing seed husks, plucking feathers, etc.), although they lack teeth and cannot chew their food.Credit: John Noll, CC BY 2.0.

The type of bird also plays a role in the decision between feather and pinion. Feathers are typically sourced from domesticated birds, such as chickens and turkeys, while pinions are sourced from wild birds, such as eagles and hawks. The size and shape of the bird's wings also play a role in the decision.
