Raisbeck Engineering and CiES Inc. Redefine Confidence in the Cockpit
In aviation, precision is not optional. Fuel quantity indication plays a critical role in safety, operational planning, and mission success. For King Air operators seeking greater accuracy and long-term reliability, Raisbeck Engineering, in collaboration with CiES Inc., now delivers a next-generation fuel quantity indication system designed specifically for the King Air platform.
This advanced solution integrates state-of-the-art magneto-resistive sensing technology with rugged, aviation-grade engineering—establishing a new standard for fuel measurement precision and operational confidence.
Purpose-Built for the King Air
Unlike legacy or adapted fuel sensing systems, the Raisbeck–CiES solution is engineered exclusively for the King Air. Each fuel sender is factory-calibrated to the aircraft’s exact fuel tank geometry, ensuring accurate readings across the entire fuel range.
There is no post-installation adjustment required and no ongoing calibration cycle. The system is ready to perform from day one.
Why Upgrade to CiES Fuel Senders?
Unmatched Accuracy and Reliability
Magneto-resistive sensor technology eliminates mechanical wear points common in traditional float-based systems. The result is consistent, repeatable accuracy and long-term reliability in real-world operating conditions.
