En-route charts are divided into high and low versions of charts, with information on airways and navaids for the purpose of high- and low-altitude flight, correspondingly. The division between the low altitude and the high altitude is usually defined as the altitude that marks transition to flight levels. It is different for different countries. for example: In the United States, this is taken to be 18,000 feet MSL by the standard convention

Minimum en route altitude (MEA), also spelled as Minimum enroute altitude, is defined as the lowest published altitude between radio navigation fixes that assures suitable navigational signal coverage and meets barrier consent necessities between those fixes.
