Infrastructure Needs For eSTOL and eVTOL Aircraft May Be Closer Than Imagined
eSTOL aircraft developer Airflow maintains that the performance of its blown wing design could match or exceed that of eVTOLs in terms of real estate needs on the ground.

With scores of eVTOL and eSTOL aircraft currently under design, construction, or even actual testing, the infrastructure needed to support them is also undergoing intense study. Take Airflow's planned hybrid-electric eSTOL model, for instance. It is being developed for middle-mile cargo missions, making trips of up to around 300 miles, directly connecting warehouses or industrial sites.

Speaking at the Vertical Flight Society's  Electric VTOL Symposium, Marc Ausman described the runway needs of his proposed blown wing aircraft as being 150 feet of ground roll with an overall requirement of 300 feet in length. That is roughly three times the length of the currently proscribed touchdown-and-liftoff (TLOF) area plus safety zone, for a helipad.
