However, if both a MEA and a MOCA are prescribed for a particular route
or route segment, a person may operate an aircraft below the MEA down
to, but not below, the MOCA, when within 22 nautical miles of the VOR
concerned (based on the pilot's reasonable estimate of that distance).

Idle curiosity: From whence came the magic 22 nm. number?
The VOR turns into a pumpkin at 22.1 nm?
