True or False: A TCAS II equipped aircraft can send a Resolution Advisory (RA) to a Mode S equipped aircraft without TCAS.

True or False: A TCAS II equipped aircraft can send a Resolution Advisory (RA) to a Mode S equipped aircraft without TCAS.

• A. True
• B. False
• C. Depends on aircraft model
• D. Only in specific conditions

Answer: (B)

A TCAS II equipped aircraft cannot send a Resolution Advisory (RA) to a Mode S equipped aircraft that lacks its own TCAS system. This is because TCAS relies on its own onboard equipment to process traffic advisories and generate resolution advisories based on the data received. While Mode S is a transponder protocol that allows for enhanced communication and identification of aircraft, it does not provide the TCAS functionality. Therefore, a Mode S equipped aircraft without TCAS is not able to receive or interpret RAs, rendering the statement false. TCAS systems are designed to provide autonomous traffic collision avoidance, and for effective functioning, both aircraft involved in the encounter need to have TCAS. Thus, the ability to communicate RAs is contingent upon the receiving aircraft also being TCAS equipped.
