Abstract – The accelerated growth in aircraft industries desires effectual scheme, programs and innovative designs of advanced systems for accomplishing the augmenting need for home-free air transportation. For safe, efficient landing and take-off of aircraft in future, magnetic levitation technology could turn out to be the best alternative to conventional landing gear system. Thus, this review will focus on the currently available technologies in aircraft landing gear system and also the magnetic levitation concept. The magnetic levitation system will be electrically powered and thus can be better served by the renewable sources, increasing safety and reducing harmful influence on the environment caused by taking-off and landing aircraft. The track of the magnetic levitation will reduce the amount of collisions and accidents. Take–off and landing in Maglev airplanes are much faster due to the elimination of the rolling resistance and will potentially improve the power efficiency.

I. INTRODUCTION
About 50% of the total aircraft accidents are due to the failure of the landing gear [1]. Today and in the future, noise levels are regulated by local and aviation authorities. As the predefined noise levels cannot be exceeded, noise–constrained airports have difficulties to expand and are limited in the amount of daily operation at the airport. This is mainly because of the landing and take-off track system which optimized by another airplane. Every airplane need to reach the optimized speed in order to take-off or landing. The average speed an airplane to take-off is from 120 kts to 155 kts (i.e. kts is knots unit used for aircraft velocity), which is around 240 km/h to 280 km/h [2]. Moreover, when the flight takes off the fuel which is fully used is up to 25 to 40% [1].
Redesign the magnetic levitation (Maglev) assisted take-off system can be a manner for the airport to be able to expand without violating the noise regulation due to the lower thrust setting required by the aircraft to take-off [3]. The primary source of noise pollution during take-off it’s from the engine of an airplane. Magnetic levitation for the landing system directly translates to a reduction in the equivalent perceived noise level (EPNL) [3].
