The Impact Of Unscheduled Maintenance To An Airline’S On Time Performance, Augusto Dalazen, Beatriz Barbi, Beatriz Ponzoni, Giovanna Simões, Lucas Kamalakian

Student Works

Unscheduled maintenance events have a significant impact on airlines performance and network operations. Some events can have its consequences minimized by simple actions due to its simplicity and lack of influence in the safe conduction of a flight.

This study aimed on collecting data regarding the cost and consequences of ground turn back events in the Airbus A320 family. The study suggested that after the implementation of proper supporting regulation on Crew Applied MEL, money would be saved as well as network disruption consequences could be avoided.

The data presented in this study reflects current Brazilian legislation, and data from …

Scheduling Aircraft Departures To Avoid Enroute Congestion, Johannes Martinez 2022 University of Minnesota - Morris

Scheduling Aircraft Departures To Avoid Enroute Congestion, Johannes Martinez

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

When scheduled flights are forecast to overcrowd sections of enroute airspace, an air traffic control authority may need to delay departures. Mixed integer linear programming can be used to compute a schedule that resolves the congestion while bringing the sum of all delays to a minimum. Standard linear programming constraint formulations for such scheduling problems, however, have poor run times for instances of realistic size. A new constraint formulation based on cycles and paths through a route graph reduces run times in computational experiments. It shows particularly strong performance for schedules that approach the worst-case solution times in standard formulations.

Characteristics Of Unmanned Aircraft System (Uas) Sightings And Airport Safety, Cheng Wang, Sarah M. Hubbard 2022 Minnesota State University, Mankato

Characteristics Of Unmanned Aircraft System (Uas) Sightings And Airport Safety, Cheng Wang, Sarah M. Hubbard

Journal of Aviation Technology and Engineering

This paper presents the characteristics of unmanned aircraft system (UAS) sightings and discusses these characteristics in the context of airport safety using airport operational data. An unmanned aircraft in the vicinity of a commercial airport may be a potential threat to aircraft operations, and may result in operational and economic impacts if it causes an airport delay or shutdown. To ensure a record of UAS activity, the Federal Aviation Administration collects and publishes a UAS Sightings Report. This study analyzed UAS sightings and found that they vary by time of year and time of day, with more sightings in the …

Classifıcation Of Survivor/Non-Survivor Passengers In Fatal Aviation Accidents: A Machine Learning Approach, Tüzün Tolga İnan Dr.

International Journal of Aviation, Aeronautics, and Aerospace

The safety concept primarily examines the most fatal (resulting in dead passengers) accidents of aviation history in this study. The primary causes of most fatal accidents are; human, technical, and sabotage/terrorism factors. Although the aviation industry started with the first engine flight in 1903, the safety concept has been examined since the 1950s. The safety concept firstly examined the technical factors, and in the late 1970s, human factors started to analyze. Despite these primary causes, there have different factors that affect accidents. So, the study aims to determine the affecting factors of the most fatal accidents to classify the survivor/non-survivor …

Noise And Time Pressure Effects On Situation Awareness And Aviation Maintenance Tasks, Syaza R. M. Haris 2021 Embry-Riddle Aeronautical University

Noise And Time Pressure Effects On Situation Awareness And Aviation Maintenance Tasks, Syaza R. M. Haris

Doctoral Dissertations and Master's Theses

Aircraft maintenance technicians (AMTs) working in a line maintenance work setting are very susceptible to the deafening occupational noise from the airport vicinity or the maintenance machinery itself. Compared to a base maintenance working period, a line maintenance job requires AMTs to complete a task within a short time frame. The current study's objective is to determine if different noise levels and time pressure influence AMTs' performance and situation awareness (SA). Sixteen Embry-Riddle Aeronautical University students majoring in Aviation Maintenance Science participated in a within-subject experimental design. Each participant's performance, SA level, and perceived workload were measured during maintenance tasks …
