Which items should be reviewed carefully when planning mountain operations?

• A. MEA And MORA
• B. Flight Times
• C. Passenger Manifests
• D. Fuel Density

Answer: (A)

In mountain operations, ensuring terrain and obstacle clearance is central, so altitude planning relies on MEA (minimum en route altitude) and MORA (minimum off-route altitude). MEA sets the lowest altitude you can fly along each segment to guarantee obstacle clearance and reliable navigation signal, which is crucial when threading through mountains where peaks and ridges can be hazardous. MORA provides the minimum altitude you should maintain when you’re off the defined route, ensuring safe clearance over terrain in areas where you might deviate or navigate off-route. Together, they guide you to choose altitudes that keep you well above terrain and obstacles, accounting for navigation aids and terrain features. While other factors like flight times, passenger manifests, or fuel density matter for overall operations, they do not define the immediate terrain safety limits the way MEA and MORA do.
