Inserting 'helicopter' into 'Aircraft type/name' produces a seemingly healthy number (686) so one could be thinking that the figure was valid - but it is way off the mark........
Well, 'Helicopter' is not really what is intended as a 'Type'. If you enter S92, EC225, AW189 etc you will see them listed
You can also use * as a wildcard. For instance, searching "Aircraft Type/Name" with BEECH 200 will only return BEECH 200, however searching on BEECH*200 will return BEECH 200 and BEECH B200. Data can also be entered in any combination of the search fields to further refine your search.
The "Aircraft type/name" search field simultaneously searches on the manufacturer, full type name, popular name and generic name of the aircraft. If you are unsure of the designation of an aircraft put in the simplest description of the aircraft (generic name), e.g. PA34 for a Piper PA-34-200T, a single line listing of all examples will appear. From the information displayed you will be able to refine your search to reduce the number of records retrieved.
Alternatively enter the popular name for the aircraft, e.g. Citation for a Cessna 500, a single line listing of all examples will appear. From the information displayed you will be able to refine your search to reduce the number of records retrieved.
The "ICAO Aircraft Type Designator" field searches on the two, three or four letter designator code published by ICAO under "DOC 8643 - Aircraft Type Designators" at
www.icao.int . The search phrase entered should be an exact match of the ICAO Aircraft Type Designator, e.g. a search for designator A31 will only return A31 and will not return A310, A318 and A319.
