    Which fuel tank sensor type should I get?

    The method is similar but it is different technology. EI uses a Hall effect sensor, and CiES uses an AMR sensor. AMR is used extensively in automotive for drive by wire functions. Throttle pedal and throttle plate, brakes, crankshaft position sensing i has supplanted hall devices as it...

    Psychology of fuel management

    Interesting - I had the opportunity to rewrite the FARS on Fuel Quantity and I with others removed the ambiguous language. Basically, it reads from full to empty where full is the placard exact value found on every certified aircraft wing and zero is the end of usable fuel . As for the...

    You can, not really a step forward from 1968 when it was designed. Linearization of the tank was catch as catch can and this was true of most analog gauging of the time. Pennycap was an apt term for the system, renting the barfield to diagnose was $$$$$mucho dinero cap. An addressable...

    Flew A Cirrus today. Long

    I designed that knob - it is a 3 position rotary switch in the form factor of a flap on a wing. It was the former company so I don't have a picture. It was what Cirrus asked for . When we did the Columbia/TTx the center light bar flashed while the flap was in transition

    You wouldn't design a system to be not trusted - that would be foolish and a waste of effort. Cirrus relies on our fuel quantity system to signal the automatic switching of the fuel tanks on the SF50 Jet, failure to do so accurately and reliably would result in temporary fuel starvation and...

    Dan. Good luck with that. The average is more for detecting lowering level of fuel. All of what you said is correct, however this will be an owner modification. There are better ways to handle the picofarad differences with modern electronics and processors. The dog simple butter...

    How does this even happen??

    The North Cascades of Costa Rica I believe that is the best answer - Nice to catch I like videos with something a little different

    How does this even happen??

    You can set a 2 position switch the Two levels it is in the Aerospace manual

    How does this even happen??

    I'm glad the senders are finally where they belong - The dimmer is easy to add, but I found the onscreen dimmer to be easier . Hooking the dimmer up to the aircraft lighting dimmer is problematic as they have a dead zone to let the Garmin auto dim. You can output to the Rochester Gauge in...

    I am betting our solution is an 2 AMU and the problem is resolved forever. No fiddling - no jury rigging. Problem solved

    We hold TSO Approval and we are STC'd - What component part of 21.303 are you referring to?

    It will that is the design nature of a potentiometer in a fuel volume - or fix the problem permanently as we guarantee them for life

    C172S fuel gauge drops to zero

    All things are possible - including fuel level averaging

    C172S fuel gauge drops to zero

    The senders are now STC'd for a majority of GA aircraft
