What is a requirement when climbing to a new MEA?

When climbing to a new Minimum Enroute Altitude (MEA), the requirement is to be at the new MEA upon reaching the fix. This is crucial for maintaining safe vertical separation from other aircraft and obstacles. The MEA provides a guaranteed safe altitude that accounts for terrain clearance as well as signal reception from navigation aids.

By reaching the new MEA exactly at the defined fix, pilots ensure compliance with the regulations and maintain situational awareness in the enroute environment. This practice also aids in preventing any altitude deviations, which is critical for maintaining safety and effective traffic management in busy airspace.

The necessity of adhering to this guideline helps establish continuity in altitude management, ensuring that any climbs or descents are performed in accordance with air traffic control instructions and established procedures.
