MOCA or MEA
Hey folks,
quick question.........can't really make out the diff between the two in the Jepps, the only difference I can see is the MOCA applies to VOR or off airway routes? Can anyone clarify and make it more specific? Does it have anything to do with signal reception?
Thanks

Mea - Moca
MOCA – Minimum Obstruction clearance Altitude. This altitude is based on taking the highest obstruction (natural or person made) in an airway segment and applying the required obstacle clearance. It could be considered an emergency minimum altitude.
MEA – Minimum Enroute Altitude. This altitude must ensure obstacle clearance (MOCA) and navigation aid reception when flying an air route in uncontrolled airspace. In controlled airspace add ATC communications and here in Canada the MEA must be at least 2200 feet above terrain.

See page 8 and page 57 under the Introduction section of your Jeppy route manual. Page 8 gives the definitions and 57 shows an illustration. Jepp uses MORA, its own derived figure, for off-route work. The figure on the chart usually has a small "a" after it. MOCA has a "T" after the number. MEAs have no letters after the alt figure.
