When are traffic alerts typically issued by Air Traffic Control?

Traffic alerts are typically issued by Air Traffic Control when there is a potential for collision with another aircraft or vehicle. This proactive communication serves to enhance safety by providing pilots with timely warnings and information about nearby traffic that may pose a risk to their flight. The goal is to allow the flight crew to take appropriate measures, such as adjusting altitude or course, to maintain safe separation from other aircraft.

In the context of the other options, it’s important to note that traffic alerts are not specifically tied to favorable weather conditions, pilot requests for information, or confined to takeoff and landing phases. Weather can play a role in overall operating conditions, but traffic alerts focus specifically on proximity and threats from other aircraft. Similarly, while pilots can request information about traffic, that request does not trigger an alert unless there is an identified risk. Traffic alerts can apply at any phase of flight, not just during takeoff and landing, reflecting the ongoing nature of air traffic management.
