The throttle levers provide input to which control unit?

The throttle levers provide input to which control unit?

• A. Each lever provides input to its respective engine FADEC.
• B. They do not feed any FADEC, only display.
• C. They control fuel pumps directly.
• D. They are linked to a single central throttle controller only.

Answer: (A)

The throttle levers are the pilot’s primary input for engine thrust, and that signal is read by the engine’s FADEC. In the Growler, each engine has its own FADEC, so the position of the corresponding throttle lever is sent to that engine’s FADEC to determine fuel metering and other control actions. The FADEC uses this input, along with sensor data, to manage ignition, compressor variables, and safe limits to achieve the requested power. So the lever input isn’t a display and it doesn’t directly drive fuel pumps, nor is there a single central throttle controller that all levers feed. Each lever feeds its own engine’s FADEC, which then handles the engine’s operation.
