Fields (28)

Field	Type	Description	Units	Enum
effDate ← EFF_DATE	String	The 28 Day NASR Subscription Effective Date in format YYYY/MM/DD
commLocId ← COMM_LOC_ID	String	Communications Outlet Identifier, a 3-4 character alphanumeric identifier. RCAG type outlets do not currently have a 3-4 character identifier stored in NASR.
commType ← COMM_TYPE	CommType	Communication Outlet Type. RCAG is Remote Communications Air/Ground.
