Abstract:Before an airplane can be licensed to carry passengers on commercial flights, the manufacturer must demonstrate that their airplane design can meet the evacuation requirements, commonly referred to as the 90-second certification test. Since the certification requirements use a single test, parameters that could significantly affect evacuation time are not fully understood or fully captured. One proposed method of addressing these limitations is to include simulated evacuation data in the certification process. This report examines the impact different parameters have on simulated evacuation data, such as exit availability, crew assertiveness, and passenger exit-selection behaviour. Five separate evacuations were simulated looking at these parameters (or a combination of two) and compared to a baseline design. Several of these parameters had a significant impact on simulated evacuation performance. The results of these simulations were used to make recommendations for how modelling and simulation data can be incorporated into aviation evacuation certification. This paper also recommends best practices for creating and evaluating modelling and simulation data for industry and regulators.
