Data driven collaboration achieving a net zero aviation future, by reducing fuel waste now Despite perceptions, airspace is a finite resource, essential not just for the transport of people and goods, but for defence of sovereign territory, facilitation of telecommunications, and the furtherance of science through space flight. Airspace Unlimited is an innovator in airspace usage, not only to maximise these activities by users, but to do it by reducing fuel burn and associated greenhouse gas emissions. Our Research activities have led to the development of an algorithmic-based analysis of multiple flight routing options against variables such as route charges, winds aloft and the placement of military reservations. This analysis focuses on the core elements of flight planning, which have become an increasingly sophisticated operation.
