Maybe Im going nuts, But I don't think so. I noticed that while taxiing and doing brake tests today, At about 1/4 fuel left the idle increased slightly. Barely noticable but the plane would not stop without the brakes. Only thing different about todays run was the turbine oil percentage. I used 2.5% instead of 4-5% like the last batch, Something tells me that's not the cause. Any suspects come to ind? Anything I should check on the data terminal?
Thanks! Pete
1 . Change in fuel system? filters replaced? new UAT?
the FADED runs auto calibration , if the pump runs "lighter"after a filter change or Tubing replacement the ecu needs time again to adjust.
this seesm to be your case
start the engine let it run in idle .
go slowly from idle to full throttle leave it at full for 10 seconds , come down again to idle.
problem should go away.
