Marcel,
great.
I check accuracy regularly: just refueling from
the pump and watching the numbers. If FF says
there will be in the tank still left say 23,4
liters I typically fill 42-43 liters (my tank is
68,1 liters) so it has a positive purpose made
error about 5% by K-factor.

I am extremely happy with my FC-10 (
http://www.fdatasystems.com/Products/FC-10/FC-10.html
).
As Raimo, I would be uncomfortable without a FF
now I got used to having one.
For all FF's a calibration needs to be performed,
which basically means flying of fuel and recording
times and Gallons/Liters, then doing the math. Not
a big deal. As a bit of additional safeguard, I
put the actual fuel tank content minus 6 liters in
as the maximum for the "virtual tank", and set
warning about 3 liters 'above' the real point
where main tank runs empty and switching to
reserve is required to keep the engine running.
After putting in the K-factor that came with the
sender, I burnt about 75 liters of fuel, then I
calculated that I had to make a small adjustment.
This adjustment gave me an accuracy of about 3%
over the next 250 liters burnt (or should I say
inaccuracy [Wink]). I then stopped recording all
of the time because there was hardly any variance
in the numbers. Now I check accuracy every once in
a while, usually once a year over the course of a
couple of flights.
