the range was by default set at zero when the changes were
made to the website. when the range of the aircraft has been edited
then the value will be something other than zero.
All aircraft information can be submitted for edit. There is a pencil icon next to every airplane when you click on the "Aircraft Types" link on the right side of the site when you are logged in and that shows a list of all the aircraft types in the database. Click the pencil, make the changes, and click submit. The Admins will then review and either accept or deny depending on if the edit conforms with the rules of FlyNET and is correct to the information given by the manufacturer.
