minimum obstacle clearance altitude
- minimum obstacle clearance altitude
The lowest published altitude in effect between radio fixes on VOR (very high frequency omnidirection radio range) airways, off-airway routes, or route segments that meets obstacle clearance requirements for the entire route segment and ensures acceptable navigational signal coverage only of a VOR. In the United States and some other countries, this coverage is only within 22 NM of a VOR. It is depicted on aeronautical charts as shown in the illustration.
