Abstract

Nowadays, many airlines in modern aviation utilize an Electronic Flight Bag (EFB) during flight to replace traditional paper-based systems. Considering the importance of aircraft weight and balance calculation to flight operations, the flight mission of X-123 (a small turboprop aircraft) and the current EFB market, research on weight and balance application development of X-123 on EFB in Indonesia is conducted. The research aimed to develop the application according to Indonesian regulations and to examine the weight and balance characteristics of X-123 through several simulations in a programming language, Python. Furthermore, Staff Instruction 8900 - 3.3 is analyzed to identify the factors that should be considered in EFB development. The global architecture design and substantial features are, then, proposed as an initial EFB development. In the global architecture design, the utilization of a gateway becomes important as a connection between the EFB developer and the client, providing aircraft data changes flexibility to the client. Moreover, the calculation formula is completely discussed in the calculation modules as a substantial feature and implemented in the simulation. According to simulation results, the payload weight and payload distribution changes can affect significantly the CG location. It is recommended to weigh and assign the payload before flight to ensure flight operation safety. In addition, the proposal of the architecture design and substantial features can be used as a reference and further developed by the Indonesian aviation companies.

Abstract

The technology of Unmanned Aerial Vehicles (UAVs), or drones, has rapidly evolved over the years, taking on various missions such as delivery, agriculture, mapping, surveillance, firefighting, and more. With the expanding functions of drones, the operational areas of UAVs also increase. However, there are restricted locations for UAV operations, one of which is an airport. Operating UAVs in controlled airspace requires permission from the government and local regulators. Moreover, a reliable communication system is crucial to support operations and prevent failures. This paper discussed the development of a communication system between UAV Ground Control pilots and Air Traffic Control (ATC) operators. The system utilizes strategic and tactical messages, developing the UAV communication system architecture based on the Controller Pilot Data Link Communication (CPDLC) standard operating procedures. This involved the design of the UAV Ground Control Station (GCS) communication system and the analysis of transmission power. The CPDLC system is a text-based communication system using the internet to send messages to ATC at an airport. The research methods included literature studies, collecting CPDLC messages based on documents (GOLD), developing the UAV communication system architecture, creating strategic communication standard operating procedures, designing the communication system interface on the GCS, and performing power calculations using link budget analysis. The research results indicate that the transmission power, calculated using the link budget at a distance of 100 km, is 17 dBm for payload communication and 15 dBm for telemetry communication, both meeting the minimum link margin standard of 15 dBm.
