The purpose of this course is to introduce students to the broad field of aviation, energy and the environment, i.e., the air quality and climate impact induced by flying on an airliner, and the potential approaches to mitigate this impact. Teachers are current members of the MIT Laboratory for Aviation and the Environment (LAE), and will combine their expertise to not only introduce students to this field, but also share insights of their current research. The lecture will include topics related to contrails, hydrogen and biofuels, inter modality, and electrification, among others.
