Airborne Collision System/TCAS Analysis The TCAS (traffic collision avoidance system) was introduced to reduce the risks associated to the mid-air collision between aircraft. The TCAS serves as a last resort safety system no matter the separation standard, and the TCAS is "an aircraft collision avoidance system" (Damidau, Save, Sellier, 2010 p 2). that has been designed to reduce the mid-air collision incidence. The TCAS is also used to monitor the airspace as well as other aircraft, which has been equipped with the corresponding active transponder. The TCAS is used to warn pilot, and other transponder equipped aircraft that may pose a threat to the MAC (mid-air-collision). In essence, the TACS is an airborne collision avoidance system that has been mandated by the ICAO (International Civil Aviation Organization), which needs to be fitted into all aircraft with a load of over 5,700 kg before a take off or the aircraft that has been authorized to carry above 19 passengers. For example, it is mandatory to install the TCAS I in aircraft carrying between 10 and 30 passengers. The TCAS/ACAS is SSR (secondary surveillance radar) or transponder signal used to advise pilot regarding a system failure.

System Analysis

TCAS is equipped with an appropriate interrogates and transponder used to determine the position of an aircraft using the 1.03 GHz radio frequency. The...

Moreover, the TCAS processor uses the radar altitude, pressure altitude, and discreet status to avoid collision, which also determine a level of protection within the TCAS aircraft.
Antennas: The TCAS antenna is used to receive signal and enable the S transponder to receive 1030 MHz.

Cockpit presentation: The RA display and traffic display consist of TCAS interface used to display essential information to the control unit.

The goal of the TCAS is to limit the consequence hazards within the aircraft environment. The hazard refers to any condition that is able to cause injury or death to personnel. Hazard is also a damage to a system or loss of property or equipment. It is essential to realize that hazard can occur when the aircraft is about to take off, in the air, or when an aircraft is about to land. One of the strategies that the TCAS employs to avoid hazard is the ability to determine if a treat or potential collision is about to occur. In this sense, the TCAS will interact with aircraft using the S or C transponder. The system will assign a unique 24-bit identifier to the aircraft with S transponder.
