What must be done with emergency frequencies during flight?

Emergency frequencies must be monitored at all times as conditions permit because these frequencies are crucial for ensuring safety during flight operations. They provide a dedicated channel for distress calls and emergency communications, which could be vital in critical situations where immediate assistance is required. Maintaining awareness of emergency frequencies allows pilots and crew to receive important updates, warnings, or coordination efforts from air traffic control or other aircraft, which can potentially avert disasters or enhance the response to emergencies.

Monitoring emergency frequencies is a standard operating procedure that might be crucial not only for the aircraft in distress but also for those in the vicinity. This practice embodies a fundamental safety protocol, ensuring that all personnel involved in flight operations are informed and can react swiftly, should an emergency situation arise.
