Nowadays these systems have been modernizing by means of latest electronic and information technologies available. Thus, the air traffic control and airport operations can provide ever better service to humanities of the world.
The modernized air traffic controlling system is equipped with sophisticated instruments like radar, radio and wireless communication and computer facilities to locate the flying aircraft. Many trained personnel have been working together at the ground offices to provide better service to flying aircrafts and airports. They monitor all airborne signals and give proper instructions and guidelines as required. They can trace out the locations and speed of the aircraft on voyage. Sometimes they need to inform concerned superiors to provide expert instructions for overcoming complicated situations. Their main task is developing an environment that is very much safe for the free flying of the aircrafts. Thus, the number of aircraft carrying out the flights can be increased considerably. They are also authorized to warn aircrafts if they come closer each other. The pilots and crew of the aircrafts work closely with air traffic controllers for the proper management of the air traffic system. They are also capable to predict the weather conditions prevailing around airports. So according to predictions they can arrange for the safer take off and landing of airplanes. This weather information is beneficial not only to flight passengers but also to industries which mainly depends on air cargo carriers to transport their products, materials and officials. Thus, these trained personnel have become the integral part of air traffic and airport operations.
The air traffic control consists of three main phases. The first phase is the rules and regulations to be followed by the pilots during flight. Second is the navigation system and instruments which work on the basis of electronics. This system and instruments
