How should a pilot react if they detect a conflict with another aircraft?

When a pilot detects a conflict with another aircraft, the appropriate action is to take evasive action to ensure safe separation and, if necessary, notify Air Traffic Control (ATC). This response is crucial for several reasons.

Firstly, ensuring safe separation is the pilot's primary responsibility. Pilots must act promptly to avoid potential collisions, especially in busy airspace where the risk of conflicting paths can be higher. Evasive maneuvers may involve changes in altitude or course to establish a safe distance from the other aircraft.

Secondly, notifying ATC is important for maintaining an overall situational awareness in the airspace. ATC can provide guidance, offer traffic advisories, and assist other aircraft that may also be in the vicinity. This communication can prevent further conflicts and help maintain safety in the airspace.

The other options do not adequately address the urgency of ensuring immediate safety or communication with ATC. Maintaining altitude and monitoring the situation may risk not responding quickly enough to avoid a collision. Immediately landing the aircraft is an extreme measure that might not be necessary or appropriate unless there are serious safety concerns. Switching to a different frequency, while sometimes necessary for communication, does not address the immediate need to act on the conflict detected in the airspace. Hence,
