  2. Minimum obstacle clearance altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_obstacle_clearance...

    The MOCA seen on the NACO en route chart, may have been computed by adding the required obstacle clearance (ROC) to the controlling obstacle in the primary area or computed by using a TERPS chart if the controlling obstacle is located in the secondary area. This figure is then rounded to the nearest 100 foot increment, i.e. 2,049 feet becomes ...

  3. Minimum crossing altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_crossing_altitude

    In this case, a segment of an airway ending at fix ABC has a MEA of 5200 feet MSL, and the minimum obstacle clearance altitude (MOCA) required to clear an obstacle six nautical miles from the fix within the next segment is 6620 feet MSL. The total increase in altitude from 5200 feet to 6620 feet over that distance is 1420 feet.

  4. Minimum en route altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_en_route_altitude

    Minimum en route altitude (MEA), [1] alternately spelled as Minimum enroute altitude, [2] is the lowest published altitude between radio navigation fixes that assures acceptable navigational signal coverage (see MRA) and meets obstacle clearance requirements (see MOCA) between those fixes.

  5. Lowest safe altitude - Wikipedia

    en.wikipedia.org/wiki/Lowest_safe_altitude

    Minimum obstacle clearance altitude (MOCA), an altitude which provides a predetermined vertical clearance from known obstacles within a predetermined corridor along the specified flight segment. For a published procedure, the greater of these two altitudes is the altitude which must be adhered to during that segment, and is called the Minimum ...

  8. Minimum reception altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_reception_altitude

    An MRA is determined by FAA flight inspection traversing an entire route of flight to establish the minimum altitude the navigation signal can be received for the route (which, along with obstacle clearance, defines the Minimum Enroute Altitude - MEA) and for off-course NAVAID facilities that determine a fix.
