The major aircraft manufacturer in Seattle requires the use of "air- assisted" airless sprayers for all paint operations inside their plants. Improved transfer efficiency not only saves money, but also reduces airborne contaminants and keeps their workforce safer. I'm all for their use.

There are several ways to improve transfer efficiency, but first and foremost is operator training. A well trained operator will improve transfer efficiency as the operator will be able to determine if pressures are too high or too low. Additionally, the operator will be able to adjust viscosity properly and choose the proper tip size. By matching pressure, tip size and viscosity, the optimum transfer efficiency can be achieved.
A caution on John's comment: one needs to be careful when moving the gun closer to the surface as orange peeling can be the result.

Reduce pressure, reduce viscosity, or both. In fact, both Graco and Titan are introducing tips that reduce the pressure needed to atomize coatings without creating tails on the edges of the spray pattern.
You can also improve transfer efficiency by placing the nozzle closer to the surface.
