Aero A.14
 The Aero A.14 was a Czechoslovakian biplane military reconnaissance aircraft built in the 1920s. It was essentially a slightly modified version of the Hansa-Brandenburg B.I aircraft that Aero had been built during World War I as the Ae.10 and for this reason the aircraft is sometimes referred to as the A.14 Brandenburg. When equipped with a slightly different engine (the Hiero L in place of the standard Hiero N) the aircraft was designated A.15 instead.
