Air traffic controllers use radar vectors and/or direct routeings and associated descent clearances according to Minimum Vectoring Altitudes (MVAs) to separate aircraft and expedite the flow of air traffic. MVAs meet obstacle clearance requirements and, as per ICAO PAN-OPS, when an IFR flight is being vectored by radar, ATC may assign MVAs which are below the minimum sector altitude… Learn more about Minimum Vectoring Altitudes and associated obstacle clearance responsibilities on SKYbrary.
