just happened to notice that it's got MOCA's defined in addition to the
MEA's. The segment between MANTA and PLUME, for example, has a MOCA of
2000. This is 25 miles from the nearest bit of terrain higher than a
wavetop. Anybody have any idea why there's a MOCA defined?

To define an altitude that ensures navaid reception between those two fixes?
