CIES Corporation Devices Designed For A Wide Variety Of Aircraft
The FAA has granted TSO C55a approval to CIES Corporation of Redmond, Oregon for its line of digital fuel level senders. The float-based fuel level senders are designed to replace the majority of the existing fuel level sending systems in general aviation aircraft. The proprietary and patented system provides a new level of accuracy, reliability, and stability to fuel level indication in the cockpit. CIES meets a TSO standard of 2% variance in tank volume, a standard normally reserved for corporate and commercial aircraft with corrected capacitive solutions. No other float based system meets this stringent TSO standard while achieving the intrinsically safe “no wires in the tank” requirement.

"As a manufacturer of aircraft systems, we see FAA certification as critical to our success and the foundation for everything we do," said Richard Kirkness, Vice President of CIES. "FAA approval is the result of months of hard work on the part of our team here in Redmond and could not have come at a better time for CIES as the company continues to grow and strives to achieve the goal of becoming a world class supplier of advanced systems and technologies.”
“After the successful introduction at the beginning of this year of our senders on all new Cirrus production aircraft, we began working with other manufacturers and owners groups to provide specific fuel level sending solutions for production and legacy aircraft," added Charlie Babb, General Manager of CIES. "The next logical step was to acquire FAA certification to validate our quality control system and lean manufacturing processes while making aircraft integration and approval significantly easier to obtain.”
The CIES fuel level senders require a dedicated digital fuel level display to ensure that the 1% accuracy achieved in the fuel tank is provided in the cockpit as well. As a result, CIES partnered with Aerospace Logic in Hamilton, Ontario to utilize their digital fuel level cockpit display. Aerospace Logic updated their fuel level gauging system to accept the digital communication link from the CIES digital senders.
