Introduction The current system applied in the US to control air traffic is very congested. The Very High Frequency and Amplitude Modulation channels utilized by air traffic personnel to control the movement of pilots in the commercial airline is said to be congested. Due to this, the National airspace System is now declared inefficient, leading to losses and wastages. The inefficient systems are known to cause delays, diminutive profits in the air sector, a compromise in the safety of passengers, as well as the cabin crew. In the air industry, some scholars and stakeholders have suggested a number of theories and concepts that would help ease the congestion witnessed currently. Such concepts include the introduction of models such as Free Flight and Satellite-based Air Traffic Management. Such models would require heavy investments and extensive research, which would take years before they are implemented. Since data-linking technology is critical to the safety of air transport, it is advisable for the state agencies concerned with passenger safety to introduce reliable systems such as NextGen systems, which would address the many problems faced in the air sector as regards to congestion (Dempsey, 1997). NextGen system would offer an effectual and consistent communications between pilots and air traffic regulators. However, the NextGen systems are faced with a number of challenges. This paper aims at analyzing the rudiments of NextGen systems as proposed by the FAA. The paper would further describe the main challenges that face the program. Overview of Next General Air Transport System NextGen system is popularly used to refer to the National Airspace System, which is to be implemented in the due course in various parts of the US, between the year 2012 and 2025. In the proposal, the NextGen system aspires to transform the air traffic-control system in the US. This means that the program aims at reforming air operations by substituting the ineffective ground-based system with a satellite-based system. In particular, the program would bring in GPS technology that would condense the air routes, save time and energy, decrease traffic interruption, augment capability of the airports, and allow the air regulators to supervise and administer planes with superior security limits. In this regard, it is expected that aircrafts would fly closer to each other, utilize direct routes, and keep off from unnecessary delays brought about by airport stacking. Under such a scenario, planes are forced to wait for open landing strips. The main challenge to the aviation authority is to come up with measures that would facilitate smooth implementation of the NextGen policies. This would imply that the Federal Aviation Administration would be expected to carry out an analysis of various systems in order o guarantee transformation of the air transportation system. Since its inception, the NextGen program has always had an aim of plummeting gridlock in the airspace and in the airports. The US government has been serious about the introduction of the program since in 2003, the congress approved the establishment of a joint committee referred to as JPDO. The committee would be charged with the responsibility of planning and coordinating the growth of the new system (NextGen System).
