Brazil is a country where aviation does more than move people from one airport to another. Across vast jungle, remote communities, and regions where roads can be limited or nonexistent, aircraft help carry medical care, essential goods, and people who depend on reliable transportation. That’s why accurate fuel indication matters. In our latest video, we talk about what it means for CiES technology to support pilots and operators serving some of Brazil’s most challenging and important routes. #CiES #AviationSafety #BrazilAviation #FuelIndication #GeneralAviation Special thanks to Reverb Films

"A fuel gauge only needs to be accurate when it's empty." For years, that saying was accepted as fact—and it even became a Hollywood trope, with pilots tapping the fuel gauge whenever something went wrong. In this edition of From the Founder, Scott Philiben talks about this mindset and how accurate fuel indication helps pilots make better decisions. #FromTheFounder #AviationSafety #GeneralAviation #FuelManagement #Pilots #CiES #accuratebeforeempty Special thanks to Reverb Films

When we first introduced our technology, many people questioned whether they really needed more accurate fuel indication. Today, the conversation has changed. In this edition of From the Founder, our founder reflects on one of the biggest paradigm "flips" we've witnessed over the years—from skepticism about improving fuel gauges to customers asking, "How did we ever fly without this?" Innovation doesn't just change products—it changes expectations. Hear the story behind that transformation and why accurate, repeatable fuel level indication has become an essential part of safer flying. ▶️ Watch the latest episode of From the Founder. #CiES #FromTheFounder #AccurateBeforeEmpty #GeneralAviation #AviationSafety #AircraftMaintenance #Avionics #AircraftOwners #innovations Special thanks to Reverb Films

Tech Tip Tuesday: Repeatability Matters Accurate fuel indication isn't just about getting the right reading—it's about getting the same reliable reading every time. Traditional mechanical float-arm senders can experience hysteresis, meaning the indicated fuel level may differ depending on whether the tank is being filled or emptied. The wiper moving across a resistive track can also introduce mechanical wear and electrical variability over time. CiES digital fuel senders use non-contact AMR sensing to determine float position, eliminating the wiper-to-track interface. The result is improved measurement repeatability across the operating range, giving pilots more consistent fuel level information they can trust.

We're proud to support and supply our fuel quantity solutions to Air Tractor, Inc.

There's a reason so many pilots say they wish they had upgraded sooner. Accurate fuel information brings confidence to every flight. With CiES fuel senders, pilots can move beyond the uncertainty of wandering fuel gauges and trust what they're seeing in the cockpit. Thank you, Rodrigo, for sharing your experience! #CiES #AccurateBeforeEmpty #AviationSafety #GeneralAviation #Beechcraft #Debonair #AircraftMaintenance #Avionics #PilotLife #FuelManagement #FlyingConfidence #AviationTechnology #AircraftOwners #GeneralAviationPilots

Fuel totalizers and fuel level indication serve two very different purposes. A totalizer estimates fuel remaining based on fuel flow data, but it can’t detect leaks, improper fueling, or fuel loss from an unsecured cap. Reliable fuel level indication provides an independent verification of the actual fuel onboard. At CiES, we manufacture fuel level indication senders designed to give pilots accurate, dependable fuel quantity information when it matters most. #AviationSafety #GeneralAviation #AircraftMaintenance #Pilots #Avionics #FuelManagement #CiES
