Civil tiltrotor technology will literally change the way man flies! With the advent of modern vertical flight aircraft, like the tiltrotor, air travel will accede to new levels of convenience, safety, and cost-effectiveness. Tiltrotors can operate in all weather conditions from airports or from smaller facilities called vertiports strategically located to provide convenient access to other transportation systems. In evaluating the economic viability of this mode of travel, the entire cost of the system must be included to realise the benefits of such a system, not just the cost of the aircraft or its cost of operation. When an improved air transportation system is developed, tiltrotors, because of their time savings and cost-competitiveness, will be able to compete in the 50–500 mile range with all types of aircraft as well as high-speed rail and other modes of transportation. While each mode has its advantages, tiltrotor will do well because it can add flexibility to the system and can complement the other modes and make the overall system more efficient. It will also be acceptable to the public at large because of its unique capability and low noise signature.
