Evaluation of Management System Effectiveness in the Preparation of the Aircraft for Flight in Faulty Conditions

Abstract

-Most flight delays in aviation enterprises are related to air traffic management and technical centers. This can happen for various reasons: untimely removal of defects, lack of spare parts, deficiencies in maintenance scheduling, etc. Another reason may be inefficient management in the system of preparing the aircraft for departure. The article suggests a possible option of such an assessment as well as the results obtained from the use of this methodology applied to a specific airline.

Analysis of Failure States of Functional Systems of Aircraft Such as Boeing 737 in the Airline

“…There was often a problem with the generator drive oil system, where the pressure was too low, or the oil temperature reading was incorrect. The flight crew may have an indication that the generator is not working, but the real cause is the generator drive, which, for example, does not provide the required frequency [14]. In Figure 5 it is shown that the situation has improved due to the introduction of mass fluing by the airline [10].…”

Airline Quality Assessment Methodology Taking Into Account the Flight Safety Level Based on Factor Analysis

“…In addition, a simple comparative analysis of actual and theoretically optimal rows by differences and inversions of ranks allows to evaluate the degree of accordance of the actual and desired row and to reveal chains of connected indicators. In accordance to the accepted model, we have a set of factors and indexes for airline functioning that has the following semantic value [8], [10]:…”

“…Such approach allows to take together and analyse all possible risk factors in an airline and could recommend some actions which necessary to increase strength of safety [4]- [7]. As shown in [8], by using complex approach, the airline`s activity can be presented as a group of 3 processes, where each process has its own change dynamics of influence factors, which determines those processes in the final time step:…”

Development of an Information Database for the Integrated Airline Management System (IAMS)

“…Based on this concept, five possible aircraft states can be distinguished in flight. We denote them by Si, where i = 0, 1, 2, 3, In case of a special event, a hazardious event occurs: incident or accident [3]. At the stage of analysis, the IAMS identifies the causal relationships of the development of a hazardious event, including several stages, each of which is sufficiently independent.…”
