What could indicate a potential hazard during operations with TCAS?

• A. Green advisory lights
• B. Red resolution advisories
• C. Blue traffic indicators
• D. Yellow warning lights

Answer: (B)

Red resolution advisories are critical indicators in the Traffic Alert and Collision Avoidance System (TCAS) that signal an immediate need for action to avoid potential mid-air collisions. When these advisories are issued, they indicate that the aircraft has been detected in a potentially hazardous situation, requiring the pilot to take corrective action, such as climbing or descending, as instructed by the TCAS. In contrast, the other indicators, such as green advisory lights, blue traffic indicators, and yellow warning lights, do not represent immediate threats. Green advisories are typically associated with standard operational procedures that do not require action, blue indicators denote traffic that is not currently a threat, and yellow warning lights generally indicate caution but do not necessitate immediate maneuvering. Therefore, red resolution advisories serve as the most critical signal concerning hazards during operations with TCAS, as they denote a situation where intervention is vital to ensure safety.
