The airspace concepts evaluation system: Recent improvements and analysis results

Abstract

Presents a collection of slides from the author's conference presentation. ◉ ACES has proven to be a useful tool, especially for NextGen concept analysis and benefits studies - ACES, developed by NASA, has many NextGen features “built in” - examples include time-based flow management, the ability to meet RTAs via KTG, the ability to specify arrival and departure routes and investigate direct routes (RNAV and Q-routes), the ability to model CNS, and other features ◉ ACES gets compared against real world data on a caseby- case basis as it is used - Several examples shown in this briefing - ACES is close to actual system but, as expected with any model, not exactly equal to it ◉ ACES run-time continues to improve - On track for a five-minute run time within 5 years (50K flights)
