MORA stands for what?

MORA stands for what?

• A. Minimum Offroute Altitude
• B. Minimum Safe Altitude
• C. Minimum Obstruction Clearance Altitude
• D. Minimum Enroute Altitude

Answer: (A)

MORA is the altitude you use when you’re not flying on a published airway. It stands for Minimum Off-Route Altitude and is published to guarantee obstacle clearance for routes taken off the designated routes, often in a grid on certain regional charts. The idea is to provide a safe minimum height above terrain and obstacles when you’re routing away from fixed airways, so you don’t rely on a navigation signal or airway structure for that safety. This differs from the others in a few ways: Minimum Safe Altitude is an emergency-altitude concept around a navigation facility, giving a safe clearance within a certain radius. Minimum Obstruction Clearance Altitude (or MOCA) ensures obstacle clearance along an airway and also guarantees VOR reception within 25 nautical miles. Minimum Enroute Altitude (MEA) guarantees obstacle clearance and navigation signal reception along airways. So for off-route planning, MORA is the correct term.
