FPGA-BASED IMPLEMENTATION FOR AVIONICS INDUSTRY

1. INTRODUCTIONAircraft data bus systems allow a variety of avionics equipment to communicate with one another and exchange data. Bus systems can be either bidirec-tional or unidirectional, and they can also be serial or parallel bits of data. Because of the constraints imposed by conductor length and weight, all practi-cal aircraft bus systems are based on serial data transfer. For an example, this autopilot director system has been designed using field programma-ble gate array (FPGA)-based technology and in normal situation, a word H E L O will be displayed once the main system is being switched ON. There-fore, issue with the autopilot director computers as shown in Figure 1.

2. PROPOSES SYSTEM APPLICATIONOne example system involving the autopilot is an airborne collision avoidance system (ACAS). It is an aircraft system that operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision. If the risk of collision is imminent, the system indicates a ma-noeuvre that will reduce the risk of collision. noeuvre that will reduce the risk of collision. Based on the report and schematic diagram pro-vided by aircraft maintenance engineer as shown in Figure 2, a word H E L O has not been dis-played, it just a blank computers screen. It’s show that something wrong with the circuit and its probably failed to detect any warning sign on the autopilot computer.

3. OBJECTIVES� To identify and troubleshot the problems with the schematic diagram and FPGA board.� To determine relationship between FPGA with electronics.� To appreciate electric & electronic device in avionic industry. in avionic industry.

4. RESULT AND ANALYSISFrom the task given, we are required to investi-gate and solve the issue with the autopilot direc-tor computers as shown in Figure 1, and get a word H E L O will be displayed once the main system is being switched ON. We manage to get word HELO on the FPGA screen after the modifi-cation of the logic gate at the board system. Figure 3 show the diagram after the modification process, a word H E L O has been displayed on computers screen. While Figure 4 show word HELLO that we manage to get after the modifica-tion. It’s represent the system in normal condition and manage to detect any warning sign on the autopilot computer.

5. CONCLUSIONFPGA offer many advantage and designed to be configured by a customer or a designer after manufacturing.. In addition to digital functions, some FPGAs have analog features. The most common analog feature is programmable slew rate and drive strength on each output pin, allowing the engineer to set slow rates on lightly loaded pins that would otherwise ring unacceptloaded pins that would otherwise ring unaccept-ably, and to set stronger, faster rates on heavily loaded pins on high-speed channels that would otherwise run too slow
