FAA Updates AC on Collision Avoidance Systems
The Federal Aviation Administration (FAA) has recently updated its advisory circular, focusing on the enhanced use of Airborne Collision Avoidance Systems (ACAS). This update is crucial as it aims to standardize practices, improve compliance, and enhance safety during in-flight collision risk scenarios.
With airspace becoming increasingly congested, the operational use of ACAS, including variants like TCAS (Traffic Alert and Collision Avoidance Systems), is more critical than ever. This article delves into the significance of these updates and their impact on aviation safety.
The updated Advisory Circular (AC) 90-120 provides a detailed explanation of ACAS technology and its variants: ACAS I, ACAS II, and ACAS Xa. These systems play a pivotal role in preventing mid-air collisions by offering alerts and resolution advisories (RAs) to help pilots maintain safe separation.
It also clarifies the differences between Traffic Advisories (TAs) and Resolution Advisories (RAs), and outlines how pilots should respond to each, thereby improving situational awareness and response accuracy to collision threats.
The circular stresses the importance of comprehensive training, encompassing both ground and flight instruction, including simulator exercises, to ensure pilots can effectively interpret ACAS displays and respond correctly.

The circular outlines the process for obtaining operational approval from the FAA for ACAS use, including necessary amendments to operational manuals, MELs, and training programs.
It also details the reporting procedures for various ACAS events, clarifying mandatory reporting requirements for RAs under specific conditions and outlining other reporting channels like the FAA Hotline and NASA ASRS for voluntary reporting of significant events.
By adopting the guidance in this circular, pilots can improve their operational efficiency and safety in increasingly busy terminal environments. The FAA’s updated advisory circular on ACAS is a significant step forward in aviation safety. It provides the aviation community with the necessary tools to train pilots, manage ACAS events, and comply with evolving regulations, ensuring seamless operation in complex airspace.
As the aviation industry continues to grow, such advancements in technology and regulatory frameworks are essential to maintaining and enhancing safety standards.
What is ACAS? Airborne Collision Avoidance System, a technology designed to prevent mid-air collisions.
How does ACAS work? It provides pilots with Traffic Advisories (TAs) and Resolution Advisories (RAs) to maintain safe separation.
Why is the FAA update important? It standardizes practices and enhances safety in congested airspace.
