Definition
2K2 is the FAA location identifier for a specific airport in the United States. In the Instrument Procedures Handbook, it appears in a list of airports that have been closed indefinitely, meaning the facility is no longer available for landing or instrument approach use, even though its identifier may still appear in older charts, databases, or publications.
Plain English
2K2 is a short code the FAA uses to name one particular airport. In this handbook, it is listed as an airport that has been shut down with no set reopening date, so pilots should not plan to use it.
Context Anchor
Seen on chart examples and airport symbols where the FAA identifies an airport by its location code.
Derivation
FAA location identifiers are short codes (usually three or four characters) the FAA assigns to airports, navigation aids, and other aviation facilities. Codes that mix letters and numbers, like 2K2, are typically used for smaller public-use or private airports that do not have a standard three-letter identifier.
Why Pilots Care
If an airport is listed as closed indefinitely, it cannot legally or safely be used as a destination or alternate. Pilots planning a flight need to recognize these identifiers and remove them from any route, alternate, or fuel planning, even if the identifier still appears in older databases.
Intuition Check
Do not read 2K2 as a performance number, runway number, or clearance instruction. Here it is simply an airport identifier attached to a closed-airport chart symbol.
Example Sentence 1
While reviewing the chart, the pilot noticed 2K2 was listed as closed indefinitely and selected a different alternate.
Example Sentence 2
Before departure the pilot checked the current list and confirmed 2K2 remained closed indefinitely.
