What altitude should be maintained when flying in mountainous regions in extreme weather conditions?

• A. 1000 ft above MEA or MOCA
• B. 2000 ft above MEA
• C. 1500 ft above MOCA
• D. 1000 ft regardless of terrain

Answer: (A)

Maintaining an altitude of 1000 feet above the Minimum Enroute Altitude (MEA) or the Minimum Obstruction Clearance Altitude (MOCA) when flying in mountainous regions under extreme weather conditions is essential for both safety and regulatory compliance. The MEA provides adequate obstacle clearance and assures navigational signal coverage. By flying 1000 feet above these altitudes, the pilot ensures an additional safety buffer in case of unexpected conditions, such as low visibility or turbulence, which are common in mountainous areas. This altitude also takes into account the potential for sudden changes in terrain elevation or weather conditions that can affect the handling of the aircraft. The additional altitude allows for more reaction time and mitigates the risk of midair collisions with obstacles such as mountains, towers, or other structures that may not be accounted for in navigational databases. The other options might not provide the same level of safety or may not be in line with regulatory standards that prioritize obstacle clearance and navigational reliability. In mountainous areas, adhering to these altitude guidelines is crucial to ensure the safety of the flight operation.
