# Flight Control Systems

The flight control systems consist of the [Rotor Flight Controls](#rotor-flight-controls) and [Hydraulic Power](#hydraulic-power).

## Rotor Flight Controls

The rotor flight control systems consisting of cyclic, collective, and directional controls are used to adjust the helicopter attitude, altitude, and direction of flight. For a system discussion and/or description, refer to [Rotor Flight Controls](flight-control-systems/rotor-flight-controls).

## Hydraulic Power

The hydraulic power system supplies pressurized fluid to operate the cyclic and collective flight control servo-actuators. Without the aid of hydraulic power, pilot effort to manually counteract the control feedback forces of the cyclic and collective flight controls is drastically increased. For a system discussion and/or description, refer to [Hydraulic Power](flight-control-systems/hydraulic-power).
