context_page_description: The Schleicher Ka-4 Rhönlerche II, sometimes called the KA-4 or even K 4, is a West German high-wing, strut-braced, two-seat glider that was designed by Rudolf Kaiser and produced by Alexander Schleicher GmbH & Co.
context_section_description: The Rhönlerche II was first flown 7 December 1953. Its design goals were to produce a simple, inexpensive and robust two-seat trainer for school and club use. The design was a success and several hundred were constructed.
  The Rhönlerche II is constructed with a welded steel tube fuselage and a wooden wing and tail surfaces, all finished in doped aircraft fabric covering. The 13.0 m (42.7 ft) span wing is supported by single lift struts and employs a Goettingen 533 airfoil. The aircraft's landing gear is a fixed monowheel, with a nose skid.
  The aircraft was issued a US type certificate on 28 September 1960.
