Development of the Cessna Model 210 Hydraulic Power Pack

The present power pack used on the Cessna Model 210 is an electrically driven hydraulic unit. This approach in power-pack design combines the advantages of the electric gear system and the hydraulic gear system without reducing the reliability of the total system. The hydraulic system provides light weight and remote location of power units without the use of large pushrods and their related routing problems. This, plus the low cost of electric power units and the deletion of all hydraulic components from the already crowded engine compartment, provides a very substantial improvement to the aircraft landing-gear system.
