Aviation's Effectiveness

The AER evaluated the effectiveness of aviation at advancing people’s work, relative to surface transport, in the five basic transportation contexts found around the world: the road, river, ocean, trail, and no-mode contexts. The project used missionary aviation’s functions and sub-functions as a practical framework.
