Goal: Increase aircraft throughput at the runway threshold by controlling the spacing between aircraft to a greater precision than can be accomplished today. APS is a time-based spacing concept, today’s system relies on distance-based spacing. ATC determines a spacing interval between a leading and trailing aircraft, then issues a clearance to the trailing aircraft with that interval. The trailing aircraft performs speed changes during its approach to achieve its assigned time spacing with respect to the leading aircraft at the runway threshold. The first in a chain of aircraft does not have a leading aircraft and is assigned a required time of arrival (RTA) at the runway threshold.

Towards a Cloud-Based Flight Management System

This paper summarizes the results of an initial concept exploration into the Cloud Flight Management System, or Cloud FMS, idea. Cloud FMS is a concept in which part of the aircraft’s FMS is on the aircraft itself, while another part resides in a ground-based cloud environment. This paper is limited to understanding whether this idea can be practically implemented within the current constraints of air-ground network throughput, availability, reliability, and latency. Simulation and live flight tests were conducted to study this concept, and specific findings that further fine-tune the Cloud FMS concept are provided.
