How CiES Fuel Senders Saved My Life
I have a 1956 Cessna 182. Serial number 10! When I refurbished the airplane a few years ago, I took out the old wing root sight gauges. During my G3X upgrade, I installed the CIES senders in their place. Now I can see the fuel levels on the display right in front of me. I flew to…
Unleaded Fuel? No Problem!
The recent demonstration by the AOPA showcased the ongoing transition towards unleaded aviation fuel, highlighting a significant step in sustainable aviation. On October 31, AOPA President Mark Baker piloted a Beechcraft Baron, which uniquely ran on two different types of fuel: the newly FAA-approved 100-octane unleaded G100UL fuel in one engine and the traditional avgas…
How to Test a Fuel Sender
Experiencing a malfunction in your aircraft’s fuel sending unit can be a major safety risk, especially during flight. It could lead to incorrect fuel readings, which might force you into emergency procedures you hoped to avoid. Imagine taking off for a long cross-country flight only to find yourself low on fuel much sooner than anticipated!…
Why Frequency Output for Fuel Level Indication?
CiES initially adopted a frequency output for their sender units in response to Cirrus’ specific requirements. Cirrus was utilizing the Garmin GEA71, which already had its analog inputs fully engaged. The consensus between Cirrus and Garmin was that a digital signal would enhance fuel quantity measurement. With over a decade of use, CiES has validated…
CiES Takes Flight to a New Location in Bend, Oregon
Bend, OR – Exciting developments are on the horizon for CiES, a pioneer in aviation technology! We’re thrilled to announce we’ve moved to 63049 Lower Meadow Drive in Bend, Oregon – the former site of Kirby Nagelhout Construction Co.
Maximize Aircraft Fuel Management with CiES Digital Fuel Sensors
In Larry Anglisano’s article on October 25, 2023, “Digital Fuel Sensors: Installation-Critical,” the importance of accurate fuel quantity measurements in aircraft is highlighted, especially during primary engine instrumentation system retrofits. While it may be tempting to save costs by using existing OEM analog fuel tank sensors, this often leads to compromised accuracy and reliability. The…
What is a Fuel Sending Unit? Technology Benefits & Disadvantages
What is a fuel sending unit? An aircraft fuel sending unit (also referred to as a fuel sensor, fuel sender or fuel probe) is a crucial component for measuring fuel quantity. In a modern system, the fuel sending unit employs advanced technology to accurately measure and transmit fuel level data to the cockpit instrumentation, providing…
10 Advantages of Magnetic vs. Ultrasonic Fuel Senders
Fuel senders play a crucial role in the efficient functioning of an aircraft’s fuel system, providing essential data to the pilot regarding the fuel level in the tanks. Among the various types of fuel senders available, magnetic fuel senders stand out for their unparalleled advantages over ultrasonic fuel senders. In this article, we will delve…
Why does my fuel gauge jump back and forth?
Have you ever been flying your airplane and noticed that the fuel gauge needle is jumping back and forth? This can be a concerning sight, especially if you’re not sure what’s causing it. And it can be very distracting, no matter how many times you’ve flown. There are a few possible reasons why your fuel…
9 Advantages of Magnetic vs. Resistive Fuel Senders
In the realm of aircraft fuel systems, fuel senders play a pivotal role in accurately measuring the fuel level in the tanks. Among the various types available, magnetic fuel senders have emerged as a cutting-edge technology with distinct advantages over their resistive counterparts. In this article, we will explore the nine key benefits in fifteen…
Why Aircraft Fuel Sender Repair is a Poor Longterm Solution
Fuel senders are a vital part of any aircraft. They are responsible for providing the pilot with an accurate reading of the aircraft’s fuel level. This information is essential for the pilot to make safe and informed decisions about the aircraft’s flight. However, fuel senders can malfunction for a variety of reasons. These reasons can…
13 Advantages of Magnetic Fuel Senders vs. Capacitive
Aircraft rely on precise and accurate measurement of fuel quantity to ensure safe and efficient operation. In the aviation industry, there are several types of fuel senders used for this purpose. Here we will compare magnetic and capacitive fuel senders. While both types serve the same purpose, there are significant differences between them which can…
