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