Because of the ability to isolate specific obstacles,  some MVAs may be lower than MEAs, MOCAs, or other  minimum altitudes depicted on charts for a given location.  While being radar vectored, IFR altitude assignments by  ATC are normally at or above the MVA.  Air traffic controllers use MVAs only when they are assured  an adequate radar return is being received from the aircraft.  Charts depicting MVAs are available to controllers and have  recently become available to pilots. They can be found  at http://www.faa.gov/air_traffic/flight_info/aeronav/  digital_products/mva_mia/ Situational Awareness is  in 14 CFR Parts 95 or 97, the following MIA applies: In  designated mountainous areas, 2,000 feet above the  highest obstacle within a horizontal distance of 4 NM  from the course to be flown; or other than mountainous  areas, 1,000 feet above the highest obstacle within a  horizontal distance of 4 NM from the course to be flown; or  as otherwise authorized by the Administrator or assigned  by ATC. MIAs are not flight checked for communication.  MVAs are established for use by ATC when radar ATC is  exercised. The MVA provides 1,000 feet of clearance above  the highest obstacle in non-mountainous areas and 2,000  2-41  Minimum Vectoring Altitudes (MVA)
