If an Air Force pilot is flying a RADAR approach, what should they do if their last fix is 210 NM from the destination?

When an Air Force pilot is flying a RADAR approach and finds themselves 210 nautical miles from the destination, requesting radar vector service to a closer non-RADAR facility is the most prudent action. This approach allows the pilot to receive guidance and assistance from air traffic control in navigating efficiently and safely towards an alternate airport, especially if the planned destination is still too far for a successful approach.

Radar vectoring can help alleviate concerns with distance and ensure that the pilot remains aligned with air traffic management protocols, which is critical for safety, especially in busy airspace. It enables the pilot to change their course safely and effectively, while also remaining in contact with air traffic control for support.

The other options may lead to potential issues. Filing directly to the destination without deviation might not be feasible due to the vast distance and could result in a failure to reach the destination safely. Diverting to the nearest available airport without proper guidance could present challenges, including inadequate fuel or unsuitable landing conditions. Canceling IFR and proceeding VFR could lead to loss of situational awareness and complicate navigation, especially if the weather conditions do not permit safe visual flight. Thus, requesting radar vector service is the most logical and safe choice in this situation.
