## 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

**SHCT Goals**

_**Efficient, Low Noise Proprotor**_
- Reduce Proprotor Noise by  6 dBA over current technology.

_**Contingency Power**_
- Engine technology to achieve One Engine Inoperative requirements in the terminal area at minimum cost

**< 65 DNL outside confines of vertiport**

_**Low Noise Terminal Area Approach**_
- Reduce Ground Noise Impact by  6 dBA utilizing complex approach profiles, safely, under all-weather conditions
