Traffic Collision Avoidance System
The “see and avoid” method of dealing with conflicts in the airspace, with increasing traffic congestion, poses an ever-increasing challenge, and so is deemed to be insufficient in the modern day aviation. Even the early decades of commercial aviation when the traffic was low, there were instances of near-collision and Mid Air Collison which demanded the need for the research into an automatic system that could inform the aircraft of an intruding aircraft and warn the pilots if the planes were on collision course so as to provide the pilots with sufficient time to make certain preventive maneuvers. Considering the safety of aviation, research for such a system was started form as early as the 1950s,

For this purpose, the system scans the surrounding airspace once every second, thus interrogating other transponder- equipped aircraft. So, there is a transponder to transponder communication between the two aircrafts, and so the host aircraft receives information of the other aircraft, and uses the information for predicting the flight path of the aircraft which has been communicated to. Now, if the system discovers that the nearby aircraft is actually on collision course, a cautionary area and a warning area are added, thus new three dimensional air space is created. This is to say that the collision area can change depending upon the flight state of the other nearby aircrafts. One major point not to miss is that the area is in terms of time, in…show more content…
(Traffic…..Traffic….). In addition, the intruder is displayed in a display in the cockpit to give the pilots information about its bearing and altitude. However, the TA is presented only to assist the pilots in making a visual search, and it is recommended to keep a visual separation, but any maneuvers based on the TA is not recommended. If the intruder is still on collision course and is around 20-25 seconds away from potential collision, a Resolution Advisory (RA) is issued. The RA could be a corrective one instructing the pilots to make a specific change in vertical air speed, or it could be a preventive one instructing the pilots to avoid certain deviation from the current vertical air speed. However, the pilots are trained and recommended not be make any horizontal maneuvers by the TCAS II. Once the pilots make measure to prevent collision and the potential collision is avoided, the TCAS system announces it as “clear of conflict”, and now the pilots can guide their aircrafts in normal flight as
