Quantification of Aerospace Environmental Impact S4
Module aims
This course focuses on understanding and addressing the challenge of sustainable aviation, using the analytical and computational tools employed by scientists, engineers, and regulators worldwide to monitor and minimize net damages. Basic methods such as the Breguet Range Equation and thermodynamic cycle analysis introduced in previous years will be built upon to understand first what aircraft emit, the ways in which those emissions impact the environment, and how these impacts can be understood in terms of net economic damages. The principal focus of this module is on quantitative methods, first covering fundamental techniques to estimate environmental change and extending to the theory and application of modern atmospheric simulation tools used in real-world environmental impact assessments. This module is necessarily broad: among other topics it will touch on climate science, atmospheric chemistry, ice cloud physics, and the economics of public health.
Learning outcomes
On successfully completing this module, you should be able to:
1. Calculate the magnitude and spatial distribution of emissions of key pollutants from a typical flight;
2. Explain the physical mechanisms by which different aviation emissions modify the climate, the global ozone layer, and surface air quality;
3. Quantitatively evaluate how different existing or novel aircraft designs, operational strategies, and fuels might trigger different environmental outcomes;
4. Apply modern computational tools in the estimation of aviation's climate and air quality impacts; and
5. Translate environmental impacts from aviation (or any other sector) into monetized health and climate impacts appropriate for use in regulatory settings.

Teaching methods
The module will be delivered primarily through large-class lectures introducing the key concepts and methods, supported by a variety of delivery methods combining the traditional and the technological. The content is presented via a combination of slides, whiteboard and visualizer.
Learning will be reinforced through tutorial question sheets.
Assessments
This module presents opportunities for both formative and summative assessment.
You will be formatively assessed through progress tests and tutorial sessions.
You will have additional opportunities to self-assess your learning via tutorial problem sheets.
You will be summatively assessed by a written closed-book examination at the end of the module.
You will receive feedback on examinations in the form of an examination feedback report on the performance of the entire cohort.
You will receive feedback on your performance whilst undertaking tutorial exercises, during which you will also receive instruction on the correct solution to tutorial problems.
Further individual feedback will be available to you on request via this module’s online feedback forum, through staff office hours and discussions with tutors.
