I think if there is no gps_code it's better to take the id from 'ident' column. At least this one doesn't change within OurAirports DB and you can always find it in theirs list

The gps_code field for each aerodrome is the ICAO code.
Aerodromes without gps_code can use the name or municipality attributes to display in the logbook. The ident attribute for internal database use.
