Airborne Collision Avoidance System: Keeping You Safe Skies

Airborne Collision Avoidance System (ACAS) are your silent copilot, watching over you every flight. These onboard devices work independently of air traffic control, constantly scanning the skies for other aircraft.

How It Works:

ACAS tracks nearby aircraft using their transponders.

If a potential collision is detected, ACAS issues alerts and instructions to pilots.

These instructions, called Resolution Advisories (RAs), guide pilots on how to avoid the danger.

Two Main Types:

ACAS I: Provides traffic advisories (TAs) informing pilots of nearby aircraft.

ACAS II: More advanced, offering TAs and RAs to actively prevent collisions.

TCAS – Traffic Collision Avoidance System

Benefits:

Reduces risk of mid-air collisions.

Enhances situational awareness for pilots.

Improves overall air traffic safety.

Next Generation ACAS:

ACAS technology is constantly evolving. Newer versions offer improved accuracy, range, and capabilities.

Soaring Safely:

ACAS is a crucial safety feature in modern aviation, working tirelessly to keep you safe every time you take to the skies.
