I'm building some AI traffic for FS9.Is there any website where I can find statistics on currently registered a/c?e.g. how many B737 or Cessna172 are there in US, or in UK, etc?Thank you in advance,Marco

To get you started, you can download a spreadsheet of Airbus orders & deliveries, which includes the number of aircraft in service, split by geographical area and airline, from their press centre:http://www.airbus.com/en/presscentre/#It doesn't provide a breakdown by country, but as long as you know where the airline is based you can work this out yourself.Boeing have something similar on their website which is split by country, but it covers deliveries rather than aircraft in service:http://active.boeing.com/commercial/orders...edselection.cfm

With the United States you can always use the FAA database.http://www.faa.gov/licenses_certificates/a...rcraft_inquiry/Search for Make Cessna and Model 310 - shows there are:C-310 - 346C-310A - 51C-310B - 130C-310C - 155C-310D - 152C-310E - 12C-310F - 95C-310G - 88C-310H - 81C-310I - 124C-310J - 135C-310K - 165C-310L - 122C-310N - 109C-310P - 98C-310Q - 415C-310R - 538There are 430 types of Boeing 73x aircraft, many of which are no longer flying or never flew. 19 pages of data - some of the larger groups / types: 737-322 - 77737-3H4 - 150737-522 - 35737-524 - 61737-724 - 36737-7H4 - 253 - most Southwest Airlines737-823 - 78 - most American Airlines737-824 - 99 - many Continental Airlines737-832 - 74 - most Delta Airlines737-924 - 12 - many Continental Airlines737-990 - 12 - Alaska AirlinesOne of the things which makes the database a little difficult is that: WELLS FARGO BANK NORTHWEST NA TRUSTEE in Salt Lake City, Utah"Owns" 3,463 aircraft - more than anyone else - just as the finance company owns your car.But still a very useful and interesting source.Commercial sources such as RedOne Aviation - http://icarus.red1aviation.com/index.jsp - and FBOWeb - www.fboweb.com - have much information.Perhaps the definitive source is ADU http://www.airlinedataunlimited.co.uk/But their database cost between 70 and 105 UK Pounds per year
