Abstract

Air Traffic Control system has developed in predecessor and it’s necessary to developed this system to avoid air traffic collisions, I displayed here in slides the system developed stages and future of ATC system thru satellite .

Introduction

The United States air traffic control system is safest in the world. Federal Aviation Administration and its Air traffic organization work continuously to improve the system.

The next generation will transform the national airspace system from one that is based on ground radars to one that uses satellite technology.

ATC System development in future

NextGen will have the technology and infrastructure necessary to handle the increasing air traffic expected in the coming decades. Satellite-based navigation will allow aircraft to fly more direct routes and navigate around inclement weather which will increase airspace capacity and reduce delays.

There are around 7,000 aircraft in the air over the United States at any given time.

Major systems in development

• 120. Satellite system: a system using earth satellites can provide worldwide navigation coverage with the accuracy associated with line-of-sight frequencies.

• 121. Microwave Landing System: More flexible approach paths in while ILS has served well.

• 123. Collision-Avoidance System: Two aircraft on parallel tracks may pass each other very closely.

The Airport as an operation system

• The airport as system Airport forms an essential part of the air

transport system. therefore, the point of interaction of the three major components of the air transport system:

The airport, including for these discussion purpose the airways control system – The airline – The user.

The diagram attempts to show how these interactions produce the prime parameters of operational scale. Passenger demand , airport capacity, and flight capacity.

System development of ATC:

• Stage 1 : Procedural ATC SystemStage 1 ATC system use procedural method, they

requires - flight plan - paper strips - radio system.

• Stage 2: Procedural ATC with radar assistanceIn 1960s ATC began to use radar with surveillance

approach radar (SAR). Radar could be use to monitor aircraft thru Instrument landing system (ILS).

• Stage 3: The first-generation “automated” ATC system.

Radar and computer, radar provide real-time surveillance within ATCC.

• Stage 4: Current generation radar and computer-based ATC system.

A modern automated ATC system is illustrated, with tactical and strategic controllers on modern flight deck.

Conclusions

As FAA moved transition of ATC system from radar-based to satellite based. controllers and pilots will have the advantage of this technology.

Satellite-Technology will allow controllers to guide aircraft in more direct routes through the nation's airspace.
