The objective of this systematic review is to investigate the various approaches that have been undertaken in finite element analysis (FEA) of human–seat interactions and synthesize the existing knowledge. With advances in numerical simulation and digital human modeling, FEA has emerged as a powerful tool to study seating comfort and discomfort. FEA employs various biomechanical factors to predict the contact stress and pressure distribution in a particular seat design. Given the complexity of human–seat interaction, several modeling and processing steps are required to conduct realistic FEA. The steps of how to perform an FEA simulation on human–seat interactions, the different models used, the model mesh compositions, and the material properties are discussed and reviewed in this paper. This can be used as a guideline for future studies in the context of FEA of human–seat interactions.

This report provides designs and solutions to develop an airflow system that would be placed inside the C-series cabin at Downsview testing facility. Designing a smart air quality system proved to be problematic, such as the interference with other research projects, and the requirement of having to mimic the G7500 HVAC system. However, the design proposed managed to solve those problems, in addition this report provides basic information about how ventilation system works in aircrafts, and their different types. It also provides information about the various harmful particles found inside aircraft cabins, and what kind of sensors can be used to catch and measure those particles. Finally, a sample simulation was shown to give a starting point for future research to be done.
