| Summary: | The reliability of the VHF Air to Ground communication system is critical to the safety and efficiency of flight operations, as it is the primary means of communication between pilots and air traffic controllers. Perum LPPNPI or Airnav as a company that is given the duty and authority as the provider of flight navigation services in Indonesia has routinely conducted equipment reliability reporting based on the regulation of the Director General of Civil Aviation KP 35 Year 2019. However, the current evaluation of the reliability of communication equipment facilities focuses on the subsystems of the equipment only without looking at the overall equipment in the communication system configuration.
This research was conducted to evaluate the current reliability measurement method and compare it with other methods, which are Reliability Block Diagram (RBD) and Markov Analysis. The research data collection was conducted at Airnav Denpasar by studying the configuration of VHF A/G equipment in the Aerodrome Control (ADC) service unit.
Based on the analysis, the current reliability evaluation method using reliability metrics has shortcomings because it combines transmitter and receiver equipment, and does not analyse the reliability of all equipment or the redundancy of the VHF A/G communication system configuration. By using RBD, reliability evaluation can be performed in more detail by considering other supporting equipment and system redundancies. In addition to RBD, Markov method can be used in evaluating the reliability of VHF A/G equipment redundancy and proving that equipment redundancy can improve the reliability of the whole system. These two methods can be used as alternative or additional methods by Airnav in measuring the reliability of the current communication system.
