wing area (aircraft wing dimensions). The total surface area of an airplane wing. Wing area is usually measured in square feet, and it is found by multiplying the span of the wing by its chord. wing chord (aircraft wing dimension). The width of a wing, or the distance from the leading edge to the trailing edge. wing fences. Vertical vanes that extend chordwise across the upper surface of an airplane wing to prevent spanwise airflow. wing fillet (aircraft structural component). A streamlined fairing installed between the root of an airplane wing and the fuselage. Wing fillets smooth the airflow where the wing joins the fuselage and reduce the drag caused by this junction. wing flaps (airplane secondary controls). An auxiliary control on an airplane that can be lowered to increase both the lift and drag the wing produces. Wing flaps are partially lowered for takeoff to allow the airplane to leave the ground at a slow speed. They are fully lowered for landing to allow the airplane to make a steep approach without building up excessive speed. See plain flap, split flap, slotted flap, Fowler flap, triple-slotted flap. wing heavy (flight condition). An out-of-trim condition in which an airplane flies, hands off, with one wing low. A wing-heavy condition is normally corrected by changing the rigging of the wing or by the deflection of one of the trim tabs. winglet (tip fin). 14 CFR Part 1: “An out-of-plane surface extending from a lifting surface. The surface may or may not have control surfaces.” wing loading (aircraft performance measure). The amount of load each square foot of airplane wing area must support. Wing loading is found by dividing the maximum weight of the aircraft, in pounds, by the total area of the wing, in square feet. wing nut. An internally threaded fastener with two wings protruding from its sides. The wings allow the nut to be turned onto a bolt using only the fingers. No provision is made for turning a wing nut with a wrench. wing panel (airplane structural component). A removable section of an airplane wing. Most airplane wings are made in panels, with a left and a right panel attached to a center section. The center section is often a part of the fuselage. wing rib (aircraft component). The structural member in an aircraft wing that gives the wing its aerodynamically correct cross-sectional shape. Wing ribs are mounted across the wing spars and are covered with thin sheets of metal, plywood, or cloth fabric. wing span (aircraft wing dimension). The length of an aircraft wing, or the distance from one wing tip to the other. wing-tip vortices (aircraft operation). Tornado-like disturbances produced at the wing tips any time an airplane wing is producing lift. When a wing produces lift, the air pressure on top of the wing is much lower than the pressure below the wing, and the high-pressure air below the wing spills over to the top at the tip, producing a tight spiral, or vortex, of wind. |
