For aircraft with Aspen Avionics' EFD1000 ­Evolution flight display system in the panel and an autopilot that needs analog attitude information, Aspen now offers the EA100 digital autopilot interface. The EA100 adapter converts digital attitude data to analog for older autopilots and eliminates the need to maintain old and expensive mechanical gyro systems such as the King KI256. The EA100 delivers attitude data from a single Aspen Pro PFD, or with both a PFD and MFD installation, attitude input is available from either the PFD's or MFD's AHRS sensors. If the EA100's health-monitoring algorithms detect a faulty AHRS input, it immediately disengages the autopilot. The EA100 weighs two pounds, retails for $2,495 and is certified for Class III aircraft. Aspen is planning to expand the autopilot types with which the EA100 can function so the unit can be installed in larger aircraft with other types of flight directors and autopilots.
