Definition
An unstaffed VHF radio transceiver, owned by the FAA, that gives pilots a way to talk to a Flight Service Station (FSS) from areas where direct radio contact with the FSS is not possible. The LRCO acts as a remote relay site, picking up the pilot's transmission and connecting it back to a controller at a distant FSS over a landline or dedicated link. 'Limited' means the outlet supports a narrower range of frequencies and services than a full Remote Communications Outlet (RCO).
Plain English
A small, automated radio antenna site on the ground that lets a pilot speak to a Flight Service Station specialist who is located somewhere far away. The pilot calls on a published frequency, and the LRCO carries the conversation back to the specialist.
Context Anchor
Seen in FAA acronym lists, aeronautical charts, and Chart Supplement entries where a remote radio contact point is listed for an airport or area.
Derivation
Limited' signals that this outlet offers fewer services or frequencies than a standard RCO. 'Remote' means the radio site is physically separated from the FSS specialist. 'Communications outlet' means a point of access for two-way radio contact. Together: a narrower-capability remote access point into the Flight Service network.
Why Pilots Care
Gives pilots a way to obtain weather, file flight plans, or receive ATC instructions when operating in areas without line-of-sight to the main facility.
Intuition Check
Limited does not mean the radio is unsafe or only for emergencies. It means the outlet has specific published limits, such as what frequency it uses, where it works, or what services it can provide.
Example Sentence 1
Unable to reach Flight Service directly, the pilot used the LRCO frequency printed on the sectional to close the VFR flight plan.
Example Sentence 2
NOTAMs list the LRCO frequency so pilots know how to reach ATC from the back-country airport.
