The Yale, named after the university, was produced as an export version of the AT-6 Texan advanced trainer. It became the standard advanced trainer for the BCATP in Canada and the RAF in Britain. It was used to train thousands of Commonwealth pilots for combat flying in fighters and fighter-bombers.
The Yale was well suited to its training role, as it had enough bad habits to teach inexperienced pilots to respect their future, high-performance fighters. The distinctive snarl of the Yale has long been a familiar sound in Canadian skies and is produced by its propeller tips
approaching sonic speeds when in fine pitch at high revolutions per minute (rpms).
