The International Air Transport Association (IATA) released the 2022 Global Aviation Flight Safety Report, revealing a reduction in the number of fatal accidents, compared to the 2021’s figures and to the average of the last five years. The Boeing Company gathers and studies accident data involving commercial aircraft since 1959. The last report published in August 2022 points out that the highest percentage of fatal accidents occurred in the final approach and landing phases. One of the causes of an unstable approach is the pilot’s inability to manage the aircraft’s total energy (translational kinetic and gravitational potential) during its approach since this does not have a direct indication in the cockpit. However, either low or high energy scenarios can lead to a non-stabilized approach along the final segment, representing the most common contributing factor that leads to a loss of control in flight, landing short of the runway, not being able to stop the aircraft within the its dimensions, hard landing, or tail strike. Traditionally, flight safety management systems use Flight Data Monitoring (FDM) applications to assess the risk level of flight operations, based on the volume of exceedances occurring in the various flight phases. In this paper, a significant number of Boeing 737-400 approaches at Eduardo Gomes International Airport (SBEG) in Manaus, Brazil, is analysed taking advantage of all flight data collected from a Flight Data Management (FDM) system to identify and understand possible atypical data, potential precursors of unstable approaches since the initial approach phase that can lead to accidents or incidents. A total aircraft specific energy condition monitoring method is applied to such data to determine specific low and high energy scenarios applicable to such location. The results are conveyed into pilots training recommendations to mitigate unstable approaches risks and in the final instance, avoid accidents.
