What altitude and route should be used if you are flying in IMC and have two-way radio communications failure?

When faced with a two-way radio communications failure while flying in Instrument Meteorological Conditions (IMC), the recommended action is to continue on the last assigned route or, if that is not available, on the expected route or minimum en route altitude (MEA). This guideline ensures that the pilot remains safely in compliance with air traffic control procedures, and it helps maintain the intended pathway through controlled airspace while minimizing the potential for conflict with other aircraft.

Continuing on a specified route and maintaining the last assigned altitude, expected altitude, or MEA provides a structured approach to managing the flight in a challenging situation. It allows pilots to remain predictable to air traffic control and reduces the risks of terrain or obstructions since the MEA is designed to ensure vertical clearance and safe navigation.

The other options do not align with standard operating procedures in IMC situations. For instance, flying directly to a VFR area without clear communication can lead to dangerous outcomes if it involves irregular maneuvers through controlled airspace. Descending to MEA may not be applicable if it does not lead one to a safe navigation path toward the nearest airport. Meanwhile, flying to a cleared route altitude may be ineffective if the pilot does not know how to maintain VFR conditions in IMC
