The Provost was an all-metal, single-engined, two-seat monoplane, featuring fixed conventional landing gear with a fully-castering tailwheel. It was developed to provide training that was better-suited to the increasingly-complicated operational aircraft that were then being brought into service. The main two seats in the cockpit were positioned in a side-by-side configuration, enabling the instructor to sit directly alongside the student, easing training by allowing for mutual close observation and for flight procedures to be more readily demonstrated; a third seat had been originally specified for use by an observer, but this position was later omitted following little use. The cockpit was considered to be relatively bulky amongst its contemporary rivals, a feature that did not heavily impinge upon the aircraft's overall performance. The type was designed to be easy to maintain; various components were intentionally interchangeable where possible and there was a generous provision of access hatches in the fuselage.
