Civil Aviation to 1970

For the period to 1970, an increase of up to 2-1/2 times the 1960 passenger-mile traffic is expected. Increase in air freight is more uncertain and will depend primarily on the extent to which air freight costs can be reduced. By 1970, civil fixed wing aircraft probably will reach a maximum gross weight of 350,000 lb and have longer nonstop capabilities than the present (1964) civil transports. No radical increase in speed of aircraft or required runway length is anticipated. The supersonic transport is not expected to be introduced into service until after 1970. Noise will continue to be a significant problem at many airports throughout the world. In-runway lighting, arresting devices, and improved approach and landing aid for all-weather operation will be implemented at high density airports.
