An Elementary Flying Training School (EFTS) gave a trainee 50 hours of basic flying instruction on a simple trainer like the De Havilland Tiger Moth, Fleet Finch, or Fairchild Cornell over 8 weeks.Elementary schools were operated by civilian flying clubs under contract to the RCAF and most of the instructors were civilians. For example, No. 12 EFTS Goderich was run by the Kitchener-Waterloo Flying Club and the County of Huron Flying Club.The next step for a pilot was the Service Flying Training School.
