Type Civil trainer
National origin Germany
Manufacturer Heinkel, Manfred Weiss
Maiden flight 1926
Primary user Hungarian Air Force

The Heinkel HD 22 was a trainer aircraft designed in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-struts. The pilot and instructor sat in tandem, open cockpits, and the main units of the fixed, tail-skid undercarriage were linked by a cross-axle.

The main producer of the type was Manfred Weiss in Hungary, who built the design to equip the Hungarian Air Force, which was at that time masquerading as civil flying clubs. Around 30 aircraft were purchased, making this the most significant user of the type.
