aerobatic aircraft is an aerodyne (a heavier-than-air aircraft) used in aerobatics, both for flight exhibitions and aerobatic competitions.
Most fall into one of two categories, aircraft used for training and by flight demonstration teams, which are often standard trainers or fighters, and aircraft especially designed for aerobatics, usually at the expense of other attributes, such as stability, carrying passengers or endurance.
Dates are of first flight.
