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…
