Preface

What is the difference between a Minimum IFR Altitude (MIA) and a Minimum Vectoring Altitude (MVA)? (May have multiple answers.)

1.

A MIA is the minimum altitude for IFR aircraft in each sector.

2.

MIAs are published on aeronautical charts for airways, routes, and standard instrument approach procedures.

3.

An MVA is a deep dark secret known only to TRACON controllers.

4.

An MVA is used by radar controllers because the MVA can isolate specific obstacles and permit lower altitudes than MEAs, MOCAs or other minimum altitudes.
