The iEFIS system

The iEFIS system consists of three different sized touch screen panels:

Challenger: 10.4” XVGA
Explorer: 8.5” WGA
Discovery: 7” WGA (Temporarily unavailable)

These are full feature systems and require an iBOX unit which is the central part of the system. One or two iBOX devices can share up to 8 panels.

Challenger Lite, Explorer Lite and Discovery Lite do not require an iBOX and feature built in sensors and AHRS. These variants are intended for aircraft not requiring the full interface capability and this results in lower cost and simplified installation.

A typical system is shown on the right using a single iBOX. Wiring is greatly reduced by being able to place the iBOX in a suitable location while interconnections between the systems is minimized by using effective network connections to panels and the well proven automotive CAN network interface to devices.

This image shows only a few of the many options but serves as an introduction to a possible system.

Functionality in brief

Primary Flight instruments:

Altimeter, Airspeed, Vertical speed, AHRS, rate of turn, slip, angle of attack.

Synthetic vision including 4 video sources (FLIR cameras etc), TAWS (on synthetic vision and 2D maps).

Navigation system:

Built in WAAS GPS (50 channels), connectivity to external navigation systems and radios. ARINC (G430 etc), VOR, ILS. Including built in simulated ILS/Glide slope and VOR using GPS.

Voice annunciation and alerts

Engine monitoring:

Via external RDAC modules up to 4 engines, comprehensive sensor connectivity. Suitable for any type of engine including turbines. RDAC modules greatly reduce wiring.

Redundancy:

Systems from simple to complex redundancy can be constructed using multiple sensors (AHRS etc), dual iBOX and mutiple panels. Master and backup power supplies in various topographies suported.

“Lite” systems provide self contained panels that can share sensors.

Autopilot:

Supports external autopilots (NMEA and ARINC) as well as providing a built in autopilot that can drive MGL servos directly.

The built in autopilot is one of the best in the industry and can fly even “twitchy” aircraft in all conditions. Supports one, two or three axis servo control. Autopilot includes lateral as well as vertical control and can fly glide slopes.

Connectivity (iBox):

6 x RS232, 3 ARINC RX, 1 ARINC TX. 2 x CAN. Analog nav inputs, analog/digital inputs, encoder output, general purpose outputs

“Lite”: 2 x RS232, 1 x CAN
