What is meant by the term MORA in IFR altitudes?

The term MORA stands for Minimum Off-Route Altitude. This designation is used in aviation to ensure safety during navigation in away-from-route situations, particularly for instrument flight rules (IFR). MORA represents the lowest altitude that a pilot can fly when not following a specific airway or route, ensuring that aircraft remain clear of obstacles and terrain while also considering the airspace limitations.

By utilizing the MORA, pilots can safely navigate through areas where there may not be a predetermined airway, increasing situational awareness and safety. This altitude takes into account the highest terrain and man-made obstacles in a given grid square, providing a buffer that enhances the likelihood of maintaining a safe vertical separation from potential hazards.

Other options, while related to navigation and airspace management, do not correctly define the term in question. Understanding MORA is essential for pilots as it impacts flight planning and real-time decision-making.
