What must be carefully reviewed before mountain operations?

• A. MEA And MORA
• B. Weather Reports
• C. Fuel On Board
• D. Crew Pairings

Answer: (A)

In mountain flight planning the key concern is ensuring you stay clear of terrain and obstacles at all times on the route you plan to fly. This is governed by minimum altitudes published for enroute segments and for off‑route areas. The minimum enroute altitude (MEA) sets the lowest altitude that guarantees obstacle clearance and reliable navigation signal reception along the route between navigation aids. The minimum off‑route altitude (MORA) provides the lowest altitude you can safely fly in areas between those routes, ensuring terrain clearance in mountainous terrain when you are not on the published airway. Reviewing these together before mountain operations tells you exactly how high you must fly to stay safe, even if winds or ATC routing push you slightly off course. Weather, fuel on board, and crew pairings are important for overall flight safety, but they do not define the terrain‑related altitude constraints you must meet in mountainous areas.
