An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly.
