Communication, navigation and surveillance tools help ATC controllers to fulfil their primary responsibility of preventing collisions between aircraft. These tools become more and more vital to safety and increased efficiency. With the number of flights handled increasing exponentially every year, the pressure is also rising for controllers. This creates a higher 3 for human error and makes the role of automated assistance even more important. Airport visibility is an area where automation systems currently provide a major boost. An ATC tower window serves as the main source of information to controllers while they give clearances to aircraft landing, taking off, or taxiing to and from the stand. Nevertheless, 4 such as hangars and stands, poor weather conditions, and runways that stretch into the horizon can make their job more difficult. Controllers therefore use radar displays to supplement their awareness. Automated warnings, such as those provided by a short-term conflict 5 system, let the controller know automatically if an aircraft or vehicle is attempting to enter a runway when it is already occupied. With automation, aircraft can be accurately 6 with reduced separation standards, thus it reduces the load on the controllers and increase airspace capacity. It offers 7 benefits as well, because it means there will be less flight delays and that aircraft will have their engines running for shorter times.”but one of the biggest problems with automation is that it can fail and it is therefore necessary for the system to make clear to operators when it has 8 and for controllers to recognize when this has happened. In addition, controllers are needed to be properly trained to use and 9 new automated systems. Could air traffic controllers be replaced by automated systems altogether one day? Both experts say that although the systems are proven to increase efficiency, for the next 20 years at least, humans will remain 10
