How many minutes after oceanic entry should crews typically squawk 2000?

The correct answer indicates that crews should typically squawk 2000, which is the transponder code used to signify that an aircraft is flying at a cruising altitude in the United States. This action is generally expected to occur about 30 minutes after entering oceanic airspace.

This timeframe is critical for maintaining communication and ensuring situational awareness in areas with limited radar coverage. By squawking 2000 after 30 minutes, crews can effectively indicate their position and status to air traffic control, which is particularly important because over oceans, radar coverage can be sparse. Sending this transponder code allows for better management and tracking of aircraft, enhancing safety in the often busy and congested oceanic air routes.

A shorter or longer timeframe may not sufficiently align with operational procedures established for managing oceanic flights, which aim to standardize communication and ensure safety through well-defined practices.
