What must be checked before flight into mountainous areas?

• A. MEA and Mora
• B. NOTAMs and METAR
• C. VOR test
• D. Fuel availability

Answer: (A)

When flying into mountainous areas, you need to know the safe altitudes along and off your intended route. The minimum enroute altitude (MEA) is the lowest altitude you may fly on a published route, and it guarantees obstacle clearance and reliable reception of navigation signals over that terrain. In mountains, staying at or above the MEA prevents you from colliding with high terrain while you’re on the route. The minimum off-route altitude (MORA) tells you the lowest safe altitude when you’re not on a published airway, ensuring obstacle clearance for off-route segments that pass near mountains. This helps you plan a safe altitude even if you need to deviate from the main path. Together, MEA and MORA provide essential altitude planning data to maintain safe clearance from terrain in mountainous flying. NOTAMs and METAR relate to weather and temporary restrictions, VOR testing concerns equipment accuracy, and fuel availability, while important, doesn’t directly address terrain clearance like MEA and MORA do.
