ذراع الهبوط: Landing Gear

All aircraft have some kind of arm landing wheels and brake mechanisms and damping mechanisms and the whole arm, called the landing. 

Use modern aircraft brake brakes and wheels tires and tire specially designed for aviation purposes, as he likes to be a tire capable of starting from the status of dormancy to nearly the speed of 322 km / h 200 mph when landing in addition to carrying nearly 454 tons. Often contain brake metals, especially heat-resistant, and should be able to deal with emergency situations, for example: if you cancel takeoff plane weighs 400 tons at the last moment, has been developing a set brakes anti-slip - commonly found in vehicles today - originally for vehicles plane and used to get the bulk of the available braking force in rainy or snowy runways. 

With aircraft larger or more complex arm falling retractable - as it is called-because it can be withdrawn within the wing or under the fuselage after takeoff, and honored to receive arm falling retractable we can reduce significantly traction arising from the structure of the wheels and that - otherwise - will remain suspended abroad within the air stream.
