Shops are faced with the challenge of working with a wide variety of fuel sensors given the wide variety of aircraft that come into the hangar. Unusable fuel isn’t the same as empty, but it might as well be. Worth mentioning is that FAR 23.1337 partially says each fuel quantity indicator must be calibrated to read zero during level flight when the quantity of fuel remaining in the tank is equal to a type-specified unusable fuel supply. And it’s a critical step in the installation.

The trouble with that is the old fuel senders might not even allow the new instrument’s software to pass the calibration portion of the setup. The task has to begin with good documentation, and that includes having the aircraft maintenance manual.Īt many shops there’s a tendency to keep the old senders in place and simply trying them when installing a new fuel quantity system. We’ve found that for some shops, dealing with old OEM sensors is uncharted territory. Aside from having to drain the fuel tanks, this creates extra work for the installer because chances are they’ll have to send the sensors off for overhaul.

That’s what you’ll likely find when your aircraft is in for an engine display upgrade and your avionics shop suggests-as they should-to overhaul or repair the fuel quantity senders. Here’s a primer, with also some guidance for upgrading even when a big-screen monitor isn’t your plan. In our view, whether you’re investing in a fully integrated suite like a G3X Touch or SkyView HDX, or a standalone engine display to replace the OEM gauges, it pays to spend the time and money to repair or replace the fuel senders. With engine display upgrades becoming more common than ever, we’re hearing plenty of stories from owners frustrated with their installers when the new system ends up being less accurate than expected.
The critical part of the system-the fuel quantity sensors-live deep in the fuel tank. That’s because the new display is only half the interface.
Sure, a digital fuel indicator solves the nuisance sticky/bouncing needle that plagues older systems but it might not make the system any more accurate. If you’re considering upgrading to an all-in-one engine display that also replaces the OEM fuel quantity gauges, there’s the potential for disappointment.
