System Description
3.1
EFD1000 E5 Dual Electronic Flight Instrument (EFI) system
The EFD1000 E5 contains an internal ADAHRS that is used to provide attitude, heading and air
data for the display. The EFD1000 E5 comes standard with an internal battery to provide 30-
minute operation in the event of power loss
Additional equipment is normally installed in support of the displays, including the Remote
Sensor Module (RSM), Configuration Module (CM), EA100 and optional Analog Converter Unit
(ACU). An external GPS receiver is required for IFR but is optional for airplanes restricted to
VFR. Optionally a remote VOR navigation receiver may be connected.
The EFD1000 E5 provides display of attitude, airspeed, altitude, direction of flight, vertical
speed, turn rate, and turn quality. The system can provide display of navigation information,
pilot-selectable indices (“bugs”), and annunciations to increase situational awareness and
enhance flight safety.

EFD1000 E5 Flight Display (EFD)
The EFD1000 E5 (EFD) display is a digital system that consists of a high-resolution 6” diagonal
color LCD display, user controls, photocell and Micro SD data card slot. The rear portion of
the EFD includes a non-removable electronics module that contains a full air data computer,
attitude heading reference system, power supplies, internal battery, and dual processor
electronics. Also on the rear of the unit, a fan is provided to cool the backlight and
electronics.
The EFD mounts to the front surface of most instrument panels. The electronics module and
cooling fins on the back are sized to fit into existing instrument panel holes. A recess-mount
bracket is available to mount the displays nearly flush with the instrument panel.
The mechanical design allows the instrument to be installed in a vertically oriented pair of
instrument openings, without interfering with the surrounding instruments. The installation
requires minimal mechanical modifications to most general aviation aircraft instrument
panels. The EFD contains a microSD card port and reader at the bottom of the display bezel.
When authorized, software updates and system upgrades can be installed using the card port.
This is a maintenance action that is accomplished by authorized maintenance personnel.
The EFD is a digital system and supports both ARINC 429 and RS-232 digital interfaces. In
installations with a modern digital radio installation, the display connects directly to the
interfaced equipment.
In installations that require interfaces to analog avionics (i.e., older VLOC navigation radios
and autopilots) an optional ACU is required to digitize the analog signals into ARINC 429.
