Collision Avoidance: ADS-B or TCAS March 7, 2000 INTRODUCTION Background Collision avoidance is something that has been a problem in aviation for a long time. ... Purpose The purpose of this report is to identify whether Automatic Dependence Surveillance Broadcast (ADS-B) or Traffic Alert and Collision Avoidance System (TCAS II) should be placed in all aircraft if the FAA decides that there is a need for some collision avoidance technology to be required for all aircraft. TCAS is currently required on all commercial passenger aircraft over 30 seats and ADS-B is currently being tested. Scope In this report, I will discuss: · Automatic Dependant Surveillance Broadcast (ADS-B) · ADS-Bs Advantages and Disadvantages · Traffic Alert and Collision Avoidance System (TCAS) · TCASs Advantages and Disadvantages · Summarize which system is better for collision avoidance Body ADS-B ADS-B is a collision avoidance tool that allows aircraft to transmit position, speed, heading and identification via a data link to either other aircraft in the air or on the ground and/or controllers on the ground. ... When compared with TCAS, ADS-B has the disadvantage that very few aircraft are currently equipped with any of the required technology. Many aircraft are already equipped with transponders that TCAS works with. TCAS II The Traffic Alert and Collision Avoidance System is a self contained device that interrogates the transponders of nearby aircraft and presents this information on a display in the cockpit(www. ... TCAS II is required for all aircraft operating in the United States with more than 30 passenger seats.
