Analysis of Loss of Control Parameters for Aircraft Maneuvering in General Aviation

Abstract

A rapid increase in the occurrence of loss of control in general aviation has raised concern in recent years. Loss of control (LOC) pertains to unique characteristics in which external and internal events act in conjunction. The Federal Aviation Administration (FAA) has approved an Integrated Safety Assessment Model (ISAM) for evaluating safety in the National Airspace System (NAS). ISAM consists of an event sequence diagram (ESD) with fault trees containing numerous parameters, which is recognized as casual risk model. In this paper, we outline an integrated risk assessment framework to model maneuvering through cross-examining external and internal events. The maneuvering is in the critical flight phase with a high number of LOC occurrences in general aviation, where highly trained and qualified pilots failed to maintain aircraft control irrespective of the preventive nature of the events. Various metrics have been presented for evaluating the significance of these parameters to identify the most important ones. The proposed sensitivity analysis considers the accident, fatality, and risk reduction frequencies that assist in the decisionmaking process and foresees future risks from a general aviation perspective.

The Analysis of Spatial Pattern and Hotspots of Aviation Accident and Ranking the Potential Risk Airports Based on GIS Platform

“…11:00-12:00 and 15:00-16:00 are high accident periods [6]. The research on aviation accident characteristics analysis also includes the analysis of accident phases, the impact of weather conditions on aviation accidents, and the ranking of factors affecting general aviation accidents [7][8][9][10][11].…”

Integrating the HFACS Framework and Fuzzy Cognitive Mapping for In-Flight Startle Causality Analysis

“…Examples include Man-Machine Integration Design and Analysis System MIDAS [35][36][37][38] and Integrated Safety Assessment Model (ISAM). Of pertinent interest to this article, [3] employed ISAM to evaluate general aviation safety in the National Airspace System (NAS) within an unsuccessful aircraft maneuvering context, resulting in loss of control. The ISAM utilizes event sequence diagrams (ESDs) with fault trees that depict relevant parameters and is a well-known and documented causal risk model.…”

“…We proceed on the premise that decision-making during in-flight operations involving fast-evolving challenges can be significantly tasking, cognitively [1][2][3]. However, despite normal safe flight conditions requiring constant monitoring, when an unexpected event occurs in flight, resulting in an aircraft upset, existing research has reported a loss of control (LOC) as an imminent consequence of this situation [4][5][6].…”

Research on the Determination Method of Aircraft Flight Safety Boundaries Based on Adaptive Control

“…Obviously, this is due to the fact that the original envelope value did not change with the actual icing conditions and therefore did not prevent the aircraft from exceeding its safe flight range. For this reason, it is necessary to introduce the concept of adaptive flight boundaries for icing aircraft, to dynamically determine the boundaries in real-time, and to protect the boundaries based on reliable control means [3][4][5][6].…”
