Editing Minimum reception altitude (section)

{{More citations needed|date=February 2022}}
In [[aviation]], '''minimum reception altitude (MRA)''' is the lowest altitude on an [[Airway (aviation)|airway]] segment where an [[aircraft]] can be assured of receiving signals from off-course [[Radio navigation|navigation aid]]s like [[VHF omnidirectional range|VOR]] that define a fix. An MRA is determined
by FAA flight inspection traversing an entire route of flight to establish the minimum altitude the navigation signal can be received for the route (which, along with obstacle clearance, defines the Minimum Enroute Altitude - MEA) and for off-course NAVAID facilities that determine a fix. When the MRA at the fix is higher than the MEA, an MRA is established for the fix, and is the lowest altitude at which an intersection can be determined.<ref>{{cite web |title=Instrument Procedures Handbook (IPH) |publisher=US Federal Aviation Administration  |date=2017 |url=https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/instrument_procedures_handbook/FAA-H-8083-16B.pdf |access-date=2023-12-30}}</ref>
