E5 EA100 Installation
Installation Limitations
An IFR GPS must be connected to the EFD1000 E5 that is connected to the EA100.
The EA100 must be installed in a temperature-controlled part of the aircraft.
The EA100 must not be installed on the firewall.
Maximum Ethernet cable length between the EFD and the EA100 is 30 feet.
An “A/P AHRS FAIL” light (amber) must be installed in the pilot primary field-of-view.
The FAA approved AFMS revision with the Configuration Matrix completed must be inserted in the
Airplane Flight Manual.
E5.1 Equipment Location Documentation
The AML-STC requires recording of the EA100 mounting location in the Instructions for Continued
Airworthiness. In addition, the location of the “A/P AHRS FAIL” annunciator and an accurate description
of the wire and cable routing must be shown on those figures.
E5.2 Weight and Balance
Using the EA100 weight from the table below and the moment arm of the mounting location perform a
weight and balance calculation per AC 43.13-1B Chapter 10. Also account for equipment removed
during the modification process.

E5.3 Mechanical Installation
It is recommended to mount the EA100 as close to the autopilot computer as possible.
The EA100 has no user interface, and therefore can be remote mounted in any orientation as long as it
is accessible. Orientation with the connectors facing upwards is not recommended due to the potential
for accumulated water in the connectors. The optimum mounting location is an area that minimizes
wire runs to interfacing equipment. This typically means near the autopilot computer or near the
attitude gyro it is replacing.
Locate the EA100 on an existing avionics shelf, radio rack, or cabin or cockpit floor. Attach to material
and structure that is appropriate for equipment mounting, using appropriate fasteners and corrosion
control. The EA100 is suitably protected against corrosion. Do not permit other parts of the aircraft or
cabling to abrade against the EA100. Installation of the EA100 must be in accordance with AC43.13-
2B, Chapter1 Paragraphs 100 to 114, pages 1 to 8.
NOTE
The EA100 has been tested for normal operation over a temperature range from -20C to +55C, and
for short time operations from -40C to +70C. This qualification permits installation in non-
pressurized but temperature controlled regions of aircraft operated up to 50,000ft. For all aircraft
on the EFD1000 AML STC installation in a temperature controlled region of the aircraft is
acceptable. Should an alternate location be selected the installer must validate that the temperature
in the alternate location is within the equipment’s qualified temperature range.
