Minimum Reception Altitude

Asked by: 8871 views Airspace, Commercial Pilot, FAA Regulations, General Aviation, Instrument Rating

On Victor airways, you might have noticed the fix, or intersection pin pointed by a box filled with 'R' and depicting an altitude known as MRA.

Also the chart depicts the radial from which the fix, or intersection can be determined.

As long as you are equipped with suitable RNAV equipment or DME, you can identify by its mileage however, is there any reason why FAA has established such radial alongwith MRA at the fix ?

    The FAA established the crossing radial for use by aircraft that do not have DME or RNAV systems. Since the MRA is based on that crossing radial, if you do not need to use that crossing radial, you do not need to be concerned about the MRA.

    The MRA is the minimum reception altitude – The lowest altitude at which an intersection can be determined. Since airways and intersections on them are dependent on the ability to receive a usable VOR and or DME signal, this is the lowest altitude at which flight testing has determined that a satisfactory signal is available.
