CiES Inc. is a Bend, Oregon-based designer and manufacturer of modular embedded aircraft systems and sensors. The company’s fuel-level senders have largely transformed—and bettered—fuel-management in general aviation aircraft.
Differing dramatically from marginally-reliable float and legacy capacitance fuel-sensor systems, CiES’s intelligent fuel-level sensors are precise, dependable, and safe. Comprising advanced sensor technologies, unique interfaces, and embedded software, CiES products provide pilots and aircraft operators accurate and reliable data upon which important decisions may be better and more confidently made.
On 10 August 2023, CiES’s next-generation fuel-sender—which features dynamic damping, pitch-compensation, and expanded digital communication capabilities—was granted FAA TSO-C55a Approval.
Magnetic Field Sensor technology is patented by CiES and salient to the function of the company’s fuel-level senders. The function of subject sensors is predicated upon the premise that the electrical properties of certain ferromagnetic alloys, such as permalloy, are influenced by external magnetic fields. The described phenomenon—by dint of the careful situation of magnets—can be harnessed to measure angles.
The effect approximates a compass, with the float on the surface of a volume of fuel functioning as north. After the fashion of a compass needle pointing northward in perpetuity, a CiES’s fuel-senders points, always, to the floats sitting atop the surfaces of host aircrafts’ fuel-tanks. Regardless the manner in which or the direction or degree to which the fuel-volume is displaced, CiES’s fuel-senders point unerringly to the float.
CiES’s proprietary digital fuel-quantity system utilizes high-tech sensors that facilitate accurate and repeatable measurement of aircraft fuel-quantity down to changes in fuel-level of less than 0.03-of-an-inch. The antecedent value represents considerably less than one-tenth of a U.S. gallon.
Moreover, CiES developed the fly-by-wire throttle system by which Safran Electrical & Power’s ENGINeUS electric aero-engine is managed. Subject powerplant, as energized by Electric Power Systems’ (EPS) battery module, motivates Diamond Aircraft’s eDA40—a light, two-to-three-place trainer currently slated to be the first electric aircraft certified under FAA Part 23.
Aero-TV is a production of the Internationally syndicated Aero-News Network. Seen worldwide by hundreds of thousands of aviators and aviation adherents, ANN's Aero-TV has produced over 5000 aviation and feature programs, including nearly 2000 episodes of our daily aviation news program, AIRBORNE UNLIMITED, currently hosted by Holland Lee. Now in its third decade of operation, parent company Aero-News Network, has the most aggressive and intensive editorial profile of any aviation news organization and has published nearly a half-million news and feature stories since its inception -- having pioneered the online 24/7 aviation new-media model that so many have emulated.
