“…In 2014, Ayres et al developed a risk assessment and reporting template especially for runway veer-offs at landings and take-offs [16]. Ayres' accident probability model was further modified in the study of "advanced risk assessment of runway safety areas with enhanced algorithm" [17].…”

Rapid exit taxiways enhance runway operational capacities by means of reducing the runway occupancy times of aircraft. The selection of rapid exit taxiway locations is important to achieve the optimum runway capacity. This paper presents a methodology for locating rapid exits based on excursion risk. Considering the level of severity and frequency of historical runway-related accidents and emerging use of rapid exit taxiways in the future, this study explores the associated veer-off risk at rapid exits. The proposed methodology estimates veer-off risk using three successive steps such as event probability, location probability, and severity estimation. An existing logistic regression model developed for landing overrun probability estimation is adapted for the exit taxiway facility to estimate event probability. Aircraft touchdown speed, deceleration, and runway criticality factor are the important operational parameters of this model adaptation. The aircraft turn path radius and kinetic energy at the time of veer-off are used to estimate the respective location probabilities and accident severities. As the sample analysis proves, the associated veer-off risk increases when the exits are closer to the runway threshold. The paper recommends wider taxiways and larger taxiway radii to compensate for increasing veer risks. The methodology helps for planning risk-based rapid exit taxiways for varying design, operational, and weather conditions.

Flight safety is one of the key priorities in the air transport industry. Considering historical aircraft accidents, majority of the aircraft accident occurred at airports. Among the airport related aircraft accidents, a higher percentage of accidents have taken place during the landing operations. Runway excursions such as overruns and veer-offs are the typical runway related aircraft accidents that frequently occur during aircraft landings. Thus, this paper focuses on aircraft excursion risk at the Bandaranaike International Airport (BIA) where the majority of the international flight movements are currently taking place in Sri Lanka. This paper considers different operational conditions that probably exist at BIA, and accordingly associated excursion risks are estimated. Aircraft airfield design elements such as the runway length, safety areas and the corresponding critical aircraft for the BIA are used for the estimation. Potential overrun and veer-off risks at aircraft landings are mainly focused. The methodology follows a quantitative approach which consists of event probability, location probability and consequent severity estimation steps. Among the potential weather factors, the conditions at which tailwind over 12 knots (6.17 m/s), reduced visibility and rain are the worst contributory factors for the greatest overrun risk. The paper highlights that the airfield design elements can compensate excursion risks that generate due to various spikes of the operational conditions.

Inadequações relativas ao projeto geométrico podem ser consideradas comuns em aeroportos pelo mundo. No Brasil, alguns aeroportos apresentam inconformidades de separação entre eixos de pistas de pouso e decolagem e de taxiamento paralelas que são inferiores aos requisitos exigidos pela Agência Nacional de Aviação Civil. Este trabalho objetiva avaliar o impacto de tal situação no risco de colisões associado a operações simultâneas de aeronaves em condições de operação por instrumentos. Para tanto, foi utilizado um método de análise de risco proposto pelo Airport Cooperative Research Program do Transportation Research Board com aeronaves de três categorias distintas que operam no Aeroporto Internacional de Fortaleza. Percebeu-se que há probabilidades reduzidas de acidentes acontecerem nestas condições, sendo o método apresentado um meio relevante para a análise quantitativa dos riscos operacionais em tais situações de inconformidade, podendo esta abordagem ser aplicada em casos similares.
