When conducting arrivals in a non-radar environment at night or in IMC, descent below the MEA is __.

• A. Always allowed
• B. Only authorized via published routing and approach procedure
• C. Prohibited
• D. Subject to ATC clearance

Answer: (B)

When operating arrivals in a non-radar environment at night or in IMC, you must follow published procedures to descend safely. The MEA sets the minimum altitude to guarantee obstacle clearance and reliable navigation along the route. Descending below the MEA is allowed only if you are on a published routing and approach procedure that provides the designated descent path and altitude constraints. This guarantees you stay on a controlled, charted path with defined step-downs in conditions where radar guidance isn’t available. ATC clearance alone isn’t enough unless it aligns with that published procedure, because the published route ensures obstacle clearance and navigational guidance.
