# 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](/bell-505-maintenance-guide/system-descriptions/flight-control-systems/rotor-flight-controls.md). ## 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](/bell-505-maintenance-guide/system-descriptions/flight-control-systems/hydraulic-power.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://bell-505-guide.gitbook.io/bell-505-maintenance-guide/system-descriptions/flight-control-systems.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
