After initiating radio contact with an aircraft in distress, what should you instruct the aircraft to do?

When an aircraft is in distress and you initiate radio contact, it's crucial to ensure continuous communication with that aircraft to provide the necessary assistance. Instructing the aircraft to remain on the initial contact frequency allows for a clear and uninterrupted connection between the controller and the distressed aircraft. This is essential for exchanging critical information, coordinating rescue efforts, and providing guidance to the flight crew without the risk of losing contact or confusion that could arise from switching frequencies.

The choice to change to a designated emergency frequency could create complications, as it might lead to a temporary loss of communication. Other instructions, such as initiating a descent or asking for further information, could be more appropriate once the initial contact is stabilized and the situation is assessed, but maintaining clear communication is the immediate priority. Thus, keeping the aircraft on the initial contact frequency is the best approach in this scenario.
