The edges of airplane wings cause vortices, in other words, a trail of air turbulence, usually in a spiral pattern. It was discovered that this actually adds extra "drag" on the airplane (wind resistance that the airplane must push through). Engineers found that by adding these "winglets", or "wingtip devices", the vortices were reduced, which reduced drag on the airplane, and this allowed greater fuel efficiency, which is important for commercial aviation.

Can airplane stop on air?
Rotary wing aircraft can. They are commonly called helicopters. However, fixed wing aircraft need air moving over the wings to hold them up.
How the aircraft get lift?
If you are asking how an aircraft produces lift, it is quite simple. The shape of the wing causes there to be higher air pressure below the wing than above; causing the wing to rise up, to the area of least resistance.
How aircraft fly?
Aircraft fly based on the principal of lift. Lift is the force that pushes a plane up. A wing is curved, which means the air flowing over the top of the wing is moving slower than the air moving under the wing. This faster moving air pushes up on the wing and the plane, making it fly.
In an aircraft what is a spoiler?
On large passenger aircraft, there are flat panels on TOP of the wing that pop up to distrupt the airflow (or spoil the airflow) that passes over the top of the wing. This kills the lift for that part of the wing and causes the aircraft to descend. The spoilers are deployed by inputs from the pilot when he wants to descend. During landing, the aircraft computer detects when the aircraft touches down on the runway and automatically deploys them to ensure the aircraft doesn't bounce up and try to keep fllying and helps slow it down quicker.
Do airplanes move their wings?
Some do. A few high performance jet aircraft have a movable wing, called a "swing wing" At low speeds the wing is straight out, but at high speeds the wings fold back. A helicopter is an airplane- a "rotary wing" aircraft. The rotor is not a propeller, but wings that are moved through the air. The wings of regular aircraft also move some- they flex up and down as loads change.
What part banks the airplane?
Ailerons are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft. The ailerons are used to control the aircraft in roll. The two ailerons are typically interconnected so that one goes down when the other goes up: the downgoing aileron increases the lift on its wing while the upgoing aileron reduces the lift on the other wing, producing a rolling moment about the aircraft's longitudinal axis. The word aileron is French for "little wing." The ailerons are control via the control column inside an aircraft's cockpit. If the control column is turned right, for example, then the right wing aileron will move upwards and the right wing will move downwards and the left wing aileron will move downwards and the left wing will lift, and the aircraft will roll right. On the tail of a fixed wing aircraft, the rudder is also used to conter-act the unwanted yaw, and is controlled by the foot pedals inside the cockpit. When the aircraft is rolled right using the ailerons, the rudder is turned right to help the aircraft begin its turn. The parts that help to bank the airplane are called the ailerons (on the wing next to the 'flaps') and the rudder (on the tail under the 'elevators').
How strong are aircraft wings?
very strong, they can hold up to 8 tonnes on each wing (look at the airbus A380). they are so strong because they are made up of hundreds of components inside the wing.

What is a slot on the wing of an aircraft and how does it work?
the slot is meaning that the there are angel wings flying up and in and around heaven are at halloween party
What is the structure of an aileron used in aircraft?
Ailerons are at the rear of the outer wing and operate opposite of each other (one up,other down) Their purpose is to roll the aircraft around its axis.
What is the disadvantage of swept back wing?
The surface area of the wing is slightly reduced, resulting in a reduced ability to generate lift. The effective aspect ratio is reduced, helping to increase wing tip vortices. Also, it is harder to recover from a stall with a swept wing aircraft, as the rear of the wing tends to stall first. This produces a greater nose up pitch on stalling, which is far harder to recover from than with a straight-winged aircraft.
What is the controlling surface that regulates an aircraft roll?
At the outer ends of the wings are 'ailerons'. These are like flaps, but when one goes up, the other goes down, thus the aircraft rolls.
