The fuselage length of 17 meters and wingspan of 25 meters place it within the lower range of light transport aircraft, such as the De Havilland Canada DHC-6 Twin Otter, Let L-410 Turbolet, and Cessna 208 Caravan. The internal cargo bay has a volume of about 18 cubic meters and is designed as a continuous, unobstructed compartment capable of accommodating standardized cargo containers and specialized loads such as refrigerated goods.

I don’t really understand the point of making a large cargo aircraft unmanned. It isn’t going to be able to pull maneuvers a human couldn’t survive and the weight of the human becomes neglible compared to the cargo capacity.

I would prefer a DHC-6, L-410 or Caravan modified to be able to fly unmanned any day.
