Flight Service Station Communication Facilities data including Remote Communications Air/Ground (RCAG) and Remote Communication Outlets (RCO/RCO1)

**Source:** NASR table `COM` · version `e25086c3e952` · effective 2026-04-16

> The COM.csv replaces the legacy COM.txt and AFF.txt Subscriber File data pertaining to RCAG. Unique record key is the combination of COMM_LOC_ID, COMM_TYPE, COMM_OUTLET_NAME, STATE_CODE, FACILITY_ID. Frequency related information can be found in FRQ.csv.

## Example query

```graphql
# Introspect the Com type in GraphiQL at https://api.nav.sortie.co/graphql
# Example shape (pair with a compatible root query field):
{
  # ...rootQuery... {
    effDate
    commLocId
    commType
    navId
  # }
}
```

| `longDecimal` | `Float` | Communications Outlet Longitude in decimal degree format | degrees |  |
| `facilityId` | `String` | For RCO and RCO1 types, the Identifier of the associated Flight Service Station. For RCAG types, the Identifier of the associated ARTCC. |  |  |
| `facilityName` | `String` | For RCO and RCO1 types, the Name of the associated Flight Service Station. For RCAG types, the Name of the associated ARTCC. |  |  |
