What does MRA mean?

Minimum reception altitude
In aviation, minimum reception altitude is the lowest altitude on an airway segment where an aircraft can be assured of receiving signals from navigation aids like VOR or NDB. Typically, the greater the distance between navigation aids, the higher the MRA. MRA is becoming less important with the availability of GPS satellite navigation, which allows aircraft to get navigational guidance all the way down to the ground.
