A coded identifier for an Aerodrome/Heliport. The rules according to which this identifier should be formed are as follows: 1) If the AD/HP has an ICAO four letter location indicator, this will become the CODE_ID for the Aerodrome/Heliport; 2) If the AD/HP does not have an ICAO four letter location indicator but has an IATA three letter code, then this will become the CODE_ID for the Aerodrome/Heliport; 3) If the AD/HP does not have either an ICAO four letter location indicator or an IATA three letter code, an artificially generated code will be used. This will contain a group of letters and a number. The group of letters could be the 2 letter code of the State responsible for the Aerodrome/Heliport (or one of these, if there are more than one, like ED and ET for Germany) and the number could be an integer between 0001 and 9999; 4) As an alternative to 3, it is also possible use the 2 letter code of the State responsible for the Aerodrome/Heliport and add at least four letters and/or numbers to it.
