  • Aircraft fuel indicator is a device to indicate the amount of fuel remained during flight, where accurate and consistent operation of the indicator should be maintained. Previously the Korean Utility Helicopter fuel indicator sporadically displayed abnormal sign by "8888" during flight, jeopardizing flight safety. Inappropriate EMI/EMC performance was detected during trouble shooting process. The cause of the abnormal display was found to be resulted from unstable power induced by electro-magnetic disturbance and CAN communication error. The aircraft fuel indicator design was improved and the design compatibility was verified to avoid abnormal display.

  • In this paper, we present a development of an Operation Flight Program(OFP) on Real Time Operating System(RTOS) and Java Virtual Machine(JVM) of real-time and embedded system. The OFPs are consisted of Multi Function Display(MFD), Integrated Up Front Control(IUFC), Head Up Display(HUD) and Fire Control(FC) and loaded for localization Mission Computer(MC). This paper describes the structure and implementation of a MFD OFP and middleware based on Java.

  • This paper describes the development and implementation for the SYMBOLGEN(SYMBOL GENerator) software. The SYMBOL-GEN software is for improving graphic processing speed and decreasing data communication load in ASC by genera ting and downloading off-line symbol file for HUD and MFD , which are the main display equipments in military aircraft. The SYMBOL-GEN is developed on PC using C++ language and MS Visual Studio 6.0 development tool. It is also designed to be modified and extended easily by introducing object-oriented software development technique.
