HILLER H-23 RAVEN
Title: Hiller H-23 Raven
Hiller Helicopter Co was formed in 1942 for the development and production of helicopters. Initial work on early models led to the Model 360, known as the UH-12 (a civil designation in spite of its similarity to US military designations.) This was first produced commercially in 1948 and went on to see extensive service amongst military (as the H-23 series) and civil operators. An extended cabin variant able to carry four persons entered service in 1960, known in military service as the OH-23F.
This title contains three flight manuals for various models of the Hiller family. The files have been copied from the original flight manuals and retain any colour pages.
