The winglet and red navigation light on the wing tip of a South African Airways Boeing 747-400 Many aircraft types, such as the Lockheed Super Constellation shown here, have fuel tanks mounted on the wing tips, commonly called tip tanks The wing tip of a Quad City Challenger II, formed with an aluminum bow The wing tip of a Grumman American AA-1, showing its Hoerner style design A Piper PA-28 ...
The tip tanks provide additional fuel capacity to enable longer times aloft. A jet pump installed in each tip tank transfers fuel into the wing tanks. Fuel can also flow via the flapper check valves into the wing tanks, but the lower half of the fuel in the tip tanks must be transferred with the jet pump. Most Learjet 25 aircraft were fitted ...

The non-planar wing tip is often swept back like a raked wingtip and may also be combined with a winglet. A winglet is also a special case of a non-planar wingtip. [citation needed] Aircraft designers employed mostly planar wing designs with simple dihedral after World War II, prior to the introduction of winglets.
Single-engine light aircraft fuel tanks are usually in the wings, but some aircraft have a small "header tank" between the normal fuel tank and the engine, to facilitate reliable fuel flow to the engine. On many small or very old single-engine header tanks (and even main tanks) are often mounted above and/or immediately behind the engine.
The 414 is a low-wing cantilever monoplane with a conventional tail unit and a retractable tricycle landing gear. It is powered by two wing-mounted 310 hp (231 kW) Continental TSIO-520-J horizontally opposed, six-cylinder engines. The prototype, registered N7170C, first flew on 1 November 1968, and production aircraft were available in a number ...
Drop tanks, external tanks, wing tanks, pylon tanks or belly tanks are all terms used to describe auxiliary externally mounted fuel tanks. Drop tanks are generally expendable and often jettisonable. External tanks are commonplace on modern military aircraft and occasionally found in civilian ones, although the latter are less likely to be ...
Alongside tanks, the US Army employed tracked "tank destroyers" (self-propelled anti-tank guns) based on tank hulls with more powerful guns but giving up armor protection for the crew. These were designated "Gun Motor Carriage" and followed earlier half-track designs.
