Were awed at the precision with which the GFC700 flies-on all ends of the airframe spectrum. Its no easy task to make an autopilot fly just as well in a Skyhawk as it does in a beefy 350 King Air. The G1000 NXi retrofit includes complete removal of the old autopilot system and many trash bins of old wiring. Got an old King Air with the primitive AC inverter system? That all comes out, simplifying the electrical bus and overall reliability.
