The MEF on Canadian VFR navigation charts is calculated by taking the higher value of: the top elevation of the highest obstacle plus the vertical accuracy (a variable number of feet) of the terrain source data; or; the elevation of the highest terrain plus 328 feet plus the vertical accuracy variable of the terrain source data.

A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration".

As operation outside the safe area of the chart can be fatal in the event of a power or transmission failure it is sometimes referred to as the dead man's curve ."
