The Aero A.30 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia in the late 1920s. It originated as an attempt by Aero to improve the performance of the Aero A.11, but soon evolved into quite a different aircraft, larger and more powerful than its predecessor. The aircraft is readily distinguished from other related types by the difference in spans between its wings – the upper set being of much greater span than the lower.
Prototypes of the A.30 were retrospectively designated A.130, with the A.230 the main production version. The A.330 and A.430 featured different, more powerful engines, but the latter of these did not enter production, serving instead as the prototype for the Aero A.100.
