Hi @DrewAvia, I’ve spent most of my time working on products for the Airbus A350 which was the first aircraft to be made from carbon fibre reinforced polymer. Improvements in efficiency can come from a few different ways:
> Sometimes we make a component lighter than it was before, maybe by designing it differently or using new materials. Any weight saves means less fuel will be consumed.
> I’ve also worked on electrical products like connectors where we reduced their resistance. This means less power (and therefore fuel) will be consumed.
> Lastly we sometimes find faster ways of installing or repairing our products. This reduces the maintenance cost and improves the cost efficiency of operating their aircraft.
I hope that was helpful 🙂
