Regarding stability:
Control and stability at the stall was tested in accordance with standards stipulated in A.D.M.293. The Spitfire I handling was found satisfactory and the aircraft deemed fit for service use. Of particular note it was concluded that during acrobatics: "Loops, half rolls off loops, and slow rolls have been done. These manoeuvres are easy to make and the aeroplane behaves quite normally in all of them."
