Calibrated Air Speed (CAS) is needed to get an accurate True Air Speed (TAS) readout on the D10A EFIS. Currently there is no Indicated Air Speed (IAS) offset available in the setup, so the EFIS displays IAS and the EDC10A corrects for density altitude to give a TAS with whatever error is in the IAS. Please consider adding a IAS-CAS OFFSET in the setup. The -5 knot error in my IAS displays the TAS as 5 knots less than actual, which when connected to the GPS 296 input shows a perpetual 5 knot headwind whatever direction is flown or gives an error in wind direction when the inflight wind is other than a direct headwind or tailwind.
