Overview of Capacity Program
Terminal Area Productivity (TAP)
Safely achieve clear-weather airport capacity in instrument-weather conditions:• increasing single runway throughput 12 to 15%• reducing lateral spacing below 3400 feet on parallel runways• equivalent instrument/clear weather runway occupancy time
Advanced Air Transportation Technologies (AATT)
In alliance with the FAA, enable next generation of increases in capacity, flexibility and efficiency, while maintaining safety, of aircraft operations within the US and global airspace system:• increasing terminal throughput 40%• increasing enroute throughput 20%
Short-Haul Civil Tilt-Rotor (SHCT)
Develop the most critical technologies to enable a civil tilt-rotor: • reducing perceived noise 12 dB• enabling safe terminal area operations• enabling operation with one engine inoperative
SHCT Goals
Efficient, Low Noise Proprotor
Reduce Proprotor Noise by 6 dBA over current technology.
