Disadvantages of Hydraulic Control

Although hydraulic controls ofl’er many distinct advantages, several disadvantages tend to limit their use. Major disadvantages are thie following:

1. Hydraulic power is not so readily available as that of electrical powe:r This is not a serious threat to mobile and airborne applications but moist certainly afi’ects stationary applications.

2. Small allowable tolerances results in high costs of hydraulic comi- ponents.

3. The hydraulic fluid imposes an upper temperature limit. Fire am
