Minimum Reception Altitude
What is minimum reception altitude?
Minimum Reception Altitude (MRA) is the lowest altitude at which you can reliably receive the navigation signals needed to identify an airway intersection or fix. It's established by FAA flight inspection and is published only when it's higher than the Minimum Enroute Altitude (MEA)—meaning you'd have to climb higher to "hear" the off-course navigation aid that defines the fix. Think of it as: the altitude where your radios can finally pick up the signal to nail down an intersection.
Also known as: MRA, minimum reception altitude
