This study focuses on an in-depth analysis of the causes and effects of the IAS Disagree indicator lighting up on the ATR 72-600 aircraft. This indicator is often a serious concern in the aviation world, as it can affect flight performance and safety. The Fault Tree Analysis (FTA) method is used to identify and map various potential causes that could trigger the appearance of the IAS Disagree indicator. Therefore, this study emphasizes the importance of intensive and periodic maintenance, especially on components. With proper maintenance, it is hoped that the risk of the feel diff press indicator appearing can be minimized, thereby improving the safety and reliability of the aviation system.
