Raisbeck Engineering and CiES Announce Modern Fuel Quantity System for Beechcraft King Air Fleet
SEATTLE, WA — Raisbeck Engineering, Inc. (“Raisbeck”) and CiES Inc. (“CiES”) today announced a new agreement to deliver a modern, highly reliable Fuel Quantity Indication System (FQIS) for Beechcraft King Air operators.
Building on the companies’ successful collaboration for the Cessna Caravan, the new King Air solution pairs CiES’s proven magneto-resistive sensing technology with Raisbeck’s industry leadership and customer support network. Supplemental Type Certificate (STC) approval is targeted for Q4 2025, with first customer deliveries planned for Q2 2026.
Finally! King Air Operators Can Get Accurate Fuel Quantity Readings.
The new FQIS will give pilots precise, stable fuel readings across the entire operating envelope while reducing nuisance faults and long-term maintenance burden.
“King Air operators expect mission-ready reliability, and this program delivers exactly that,” said Gregory Davis, President of Raisbeck Engineering. “CiES’s sensing technology and our customer-care capabilities are a powerful combination. We’ve developed a trust-based partnership that leverages both teams’ strengths and that translates directly into quality, speed, and support for our customers.”
“Raisbeck understands product development, integration, and the King Air market like few others,” added Scott Philiben, President of CiES. “Pairing our magneto-resistive fuel sensing, now widely adopted across OEM and retrofit applications, with Raisbeck’s support culture ensures King Air operators receive a best-in-class solution backed by a team that will stand behind it.”
“This is the upgrade our customers have been asking for,” said Nick Lyle, Vice President of Sales at Raisbeck.
“There is real pent-up demand in the King Air community for a modern, dependable fuel quantity system. We’re excited to bring this to market and begin shipping kits as soon as certification is complete.”
