AIRCRAFT NAVIGATION SYSTEM FOR FREE ROUTE AIRSPACE

摘要

Systems and methods are provided for displaying an availability for free routing within at least one free route airspace location to a pilot. The method includes the step of storing information related to at least one free route airspace location along a flight plan of the aircraft and an associated time window of availability for free routing within the at least one free route airspace locations in a memory module. The method also includes the step of comparing the stored time window of availability for free routing within the at least one free route airspace location to a system clock time. The method also includes the step of determining, on the basis of the comparison, the present availability for free routing within the at least one free route airspace location. The method also includes the step of displaying the present availability for free routing within the at least one free route airspace location to the pilot.
