Question

Flight over mountainous terrain in the winter should add an additional _________feet to your MEA or MOCA

Answer 1

Flight over mountainous terrain in the winter requires adding 1,000 to 2,000 feet to MEA or MOCA for safety against unpredictable weather and reduced aircraft performance.

Step-by-step explanation:

When flying over mountainous terrain in the winter, pilots should add an additional 1,000 to 2,000 feet to their Minimum Enroute Altitude (MEA) or Minimum Obstruction Clearance Altitude (MOCA). This extra altitude provides a safety buffer against unpredictable weather conditions and the reduced performance that aircraft might experience in colder temperatures. When considering the extra altitude, it is also important to take into account the aircraft's performance capabilities, the highest obstruction within the sector, and the margin that allows for a safe emergency descent if needed.
