What actions should a controller take if an aircraft reports an inflight equipment malfunction?

When an aircraft reports an inflight equipment malfunction, the appropriate action for a controller is to determine the nature of the malfunction and provide necessary assistance. This is crucial because understanding the specifics of the malfunction allows the controller to assess the situation adequately and prioritize the safety of the aircraft, the crew, and any passengers on board.

By engaging with the flight crew, the controller can gather essential information such as the type of malfunction, its severity, and whether the aircraft can continue its flight or needs to divert to an alternate airport. This communication helps in evaluating the best course of action, whether that involves providing additional routing, alerting emergency services, or preparing the destination airport for an emergency landing if needed.

Taking this proactive approach ensures that the controller plays an integral role in managing the safety of flight operations, rather than leaving the crew to handle the situation on their own. Understanding the nature of the malfunction is critical for effective coordination and support, making this response essential in air traffic management.
