All,
This question should have been asked before plunking down dollars: what are the precision and accuracy standards for a Dynon EFIS?
The D-10A and EDC I resently retrofitted to a flying -7 perform acceptably except that the heading tape is useless for precise flying, something akin to using a wet compass. The installation is requirements compliant, latest software loaded, functionalitites verified, compensations and calibrations completed, and assistance asked of Dynon. Yet the heading indication leads and lags turns as much as 15 degrees, error magnitude being heading dependant, turn rate inconsequential. Regaining straight and level, the tape requires 10 or more seconds to drift back to within 3-4 degrees of actual heading. The factory considers such performance within cummulative tolerances, to which I say the worst precessing DG I've ever flown behind was vastly superior.
How well does your D-10A with EDC perform?
