| Abstract | Interval Management (IM) is a future airborne spacing concept that aims to provide more precise inter-aircraft spacing to yield throughput improvements and greater use of fuel- efficient trajectories in arrival and approach environment s. To participate in an IM operation, an aircraft must be equipped with avionics that provide speeds to achieve and maintain a desired spacing interval relative to another aircraft. It is not exp ected that all aircraft will be equipped with the necessary avionics, but rather that IM fits into a larger arrival management conce pt developed to support the broader mixed-equipage environment. Arrival management concepts are comprised of three parts: a ground-based sequencing and scheduling function to develop an overall arrival strategy, ground-based tools to support the management of aircraft to that schedule, and the IM tools nec- essary for the IM operation (i.e., ground-based set-up, initiation, and monitoring, and the flight-deck tools to conduct the IM operation). The Federal Aviation Administration is deploying a near-term ground-automation system to support metering operations in the National Airspace System, which falls within the first two components of the arrival management concept. The near-term system will include sequencing and scheduling functions and tools to help air traffic controllers in managi ng aircraft to meet their scheduled times of arrival (STAs) at meter points. This paper presents a methodology for determining the required delivery accuracy at the meter points in order to achieve desired flow rates, adequate separation at the meter points, and to enable aircraft to meet their STAs while remaining on their RNAV arrivals, which will reduce costly vectoring and holding. An example based on operations at Phoenix airport is presented to illustrate the analysis framework in a real-world context. |
