Problem

Commercial jet aircraft use an auxiliary power unit (APU) for energy generation while the main engines are off. Despite airline policy, APUs are often left to run longer than necessary, resulting in excess pollution.

Approach

Team Corgo worked with SeaTac Airport to develop a system that detects, monitors and reports APU usage to aid policy enforcement.

Solution

The team built and installed three sound-gathering devices around SeaTac, which listen for specific sounds generated by APUs. This audio is analyzed by their trained machine learning model, and results are displayed on a custom dashboard.
