minimum en route altitude


minimum en route altitude
The lowest published altitude between radio fixes that ensures acceptable navigational signal coverage and meets the obstacle clearance requirement between those fixes. MEAs apply to the entire width of all airways or other direct routes. It is shown on aeronautical charts as depicted in the illustration.
Minimum en-route altitude shown as altitude or flight level on an aeronautical chart.
