This bachelor thesis includes two different manuals and design of an interface box between a test object and a general test station (computer) with ARINC429 communication.There are three different purposes with this project:The first is to setup a general test station with ARINC429 communication using a communications card from DDC (DD-42916i3-300) and software from Ampol Technologies (dataSIMS).The second is to design a new interface between the test computer and the test object. As well as implementing two components in the equipment.The third is to write two separate manuals to guide the users of this equipment. There are two different kinds of users of this equipment, technicians and system engineers. Technicians use the equipment to test and repair flight components. System engineers will implement new components in the equipment.The result of this project is a working test station with a new interface and two manuals..

The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.
