The Cessna Model 210 Hydraulic System and Its Development

This paper presents the current hydraulic system on the Cessna Model 210 aircraft and some of the problems encountered during its development. Several cross-section views of the various components are illustrated, along with a schematic of the system, to aid in explaining how the necessary sequencing is accomplished with a combination of electrically and hydraulically controlled sequencing devices. In view of the demands made of the system, it is a practical, reasonably simple, and reliable light aircraft landing gear retraction system.
