ABSTRACT
In 2020, the amount of cargo requiring haulage was surplus to the transportation facilities available. The number of commercial flights operated decreased due to Coronavirus 2019 causing lockdowns, immigration restrictions, and border closures. Stay at home measures increased demand for online shopping and deliveries. Due to the reduction in commercial airline passengers and vacancy of the passenger cabin, governmental aviation agencies and airline regulators sought permissions to transport cargo in the passenger cabin. This paper evaluates the task of transporting cargo in the passenger cabin from a cabin safety perspective. Type of cargo and cargo placement in the cabin were key areas identified, as well as fire prevention. Consideration is also given to human factors and the continuously updating standard operating procedures for which cabin crew found themselves responsible when flying weeks after the World Health Organization announced Coronavirus 2019 to be a pandemic. © 2022, American Institute of Aeronautics and Astronautics Inc, AIAA.

ABSTRACT
A method to maintain safe air quality standards in an aircraft passenger cabin will be presented. Safe air quality with respect to aerosols in a closed space is important to protect people in their environment. The COVID-19 pandemic has increased the significance of this topic. This article is based on equations from Silich (2021) and presents these prior equations in a different format that can help to provide greater insight to the behavior of aerosols in a well-mixed space. One purpose of this article is to enhance our understanding of how an aerosol behaves in a closed space where dilution ventilation is the method used to clear the aerosol. The primary focus will be that of an aircraft passenger cabin. The model used is best applied to an aviation scenario by understanding its relationship to health care ventilation requirements. © 2022.
