Advanced technology in both hardware and software design is being incorporated into today's military aircraft without fully considering the capabilities and limitations of the operator. Incorporating this new technology results in operators being disenchanted with the design due to the lack of a compatible human interface with that technology. Interface design, or in better terms, Pilot-Vehicle design, has been ignored or given minimal attention by the designers. Designers need to realize that implementing new software or hardware designs is more than coding a set of requirements or mounting a new system that ends up making the operator's tasks harder to complete. Programs at the conceptual phase need to seriously consider human capabilities meshed with the air vehicle design and its mission requirements. The antidote to this controversy is labeled Pilot-Vehicle Integration.
