The Cessna 172 Skyhawk is the most produced aircraft in history.. An aircraft (pl.: aircraft) is a vehicle that is able to fly by gaining support from the air.It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, [1] or, in a few cases, direct downward thrust from its engines.
This is the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in
Aeroflot started flying the Tu-144—the first supersonic passenger plane in 1975. The next year, British Airways and Air France began supersonic flights over the Atlantic. [151] In 1979, the Gossamer Albatross achieved the status of the first human-powered aircraft to fly over the English channel, which had been a dream for centuries. [152]
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets . In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown.
Some free-flying types use an adapted airfoil that is stable, or other ingenious mechanisms including, most recently, electronic artificial stability. To achieve stability and control, most fixed-wing types have an empennage comprising a fin and rudder which act horizontally and a tailplane and elevator which act vertically.

The techniques used for navigation in the air will depend on whether the aircraft is flying under the visual flight rules (VFR) or the instrument flight rules (IFR). In the latter case, the pilot will navigate exclusively using instruments and radio navigation aids such as beacons, or as directed under radar control by air traffic control .
The Beriev Be-2500 Neptun (Russian: Бериев Бе-2500 «Нептун») is a super heavy amphibious transport aircraft that, as of 2007, was [needs update] in design and development by Russian design firm Beriev. The maximum takeoff weight is estimated at 2500 tons, hence its name.
