Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft.
Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor.
