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...
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...
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...
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...
