EFIS Trainer AV3737

The Matrix Electronic Flight Information System consists of an EFIS with LCD display, user controls, compass
sensor, attitude sensor and a Locktronics board with additional potentiometers mimicking further sensors
on an aircraft. The sensors and the EFIS are connected with CAN bus. Students use this system and PC based
MODULE 2.0
diagnostic software to understand how complex computer based flight systems are made from separate
electronic modules linked by multiplexed signals on a serial data bus – in this case the CAN bus. Fault finding
with multimeters and oscilloscopes is included. The system links to our microcontrollers training package so
that students can understand system operation at a low level. A 50 page manual is included. This is a student
centred course that will take around 5 hours to complete.
