What are the proper actions involved in the "Lost Comm" procedures?

The proper actions involved in the "Lost Comm" procedures dictate that the pilot should attempt to regain radio communication and follow standard lost communication protocols. This is essential because the primary goal is to re-establish contact with Air Traffic Control (ATC) or other relevant entities to ensure safety and proper navigation. By following standard protocols, the pilot can also ensure that they are adhering to established procedures that have been designed to mitigate risks associated with the lack of communication.

Attempting to regain communication is crucial, as it can often resolve the situation quickly, allowing the flight to proceed as planned. Coordination with ATC provides necessary instructions and situational updates, which are particularly important during critical phases of flight. Following established protocols ensures that actions taken are consistent with those expected by ATC and other traffic, thus enhancing safety for the flight and other aircraft in the vicinity.

The other actions suggested in the options would not contribute positively to a safe resolution of the situation, as they either disregard attempting to communicate or take unnecessary actions that could complicate the flight plan or lead to unsafe conditions.
