A jet trainer is a jet aircraft for use as a trainer, whether for basic or advanced flight training. Jet trainers are either custom designs or modifications of existing aircraft. With the introduction of military jet-powered aircraft towards the end of the World War II it became a requirement to train pilots in the handling of such aircraft.
