What is indicated by a Local Standby alert?

A Local Standby alert specifically indicates that an aircraft is experiencing an operational defect but is deemed safe to land. This alert serves as a precautionary measure allowing emergency response teams to prepare for any potential issues that may arise during landing, while still ensuring that the situation is under control, and the aircraft is not in immediate danger of crashing or requiring an evacuation.

The Local Standby alert helps coordinate readiness among airport personnel and emergency services, ensuring that they can respond quickly should the situation escalate. By notifying ground services and emergency responders, it sets the stage for an effective reaction without causing unnecessary alarm or deviating from standard operational procedures.
