EFD-750 Electronic Flight Display

Product Overview

The compact, advanced EFD-750 is a scalable OEM and retrofit solution that comes standard with attitude, airspeed, altitude and slip/skid. Customized hardware configurations are available to support internal air data, or external air data from an existing digital source on the aircraft. EFD-750 also reduces maintenance time by storing all display and interface configuration data in an OEM or installer-programmed data configuration module for field-loadable software updates using the MicroSD card slot on the front bezel.
