Abstract

Methods and systems are provided for optimization of an aircraft flight trajectory with shortcuts. The method comprises retrieving an active flight plan stored in a flight management system (FMS) and identifying a potential shortcut with a shortcut advisor tool. The FMS monitors the location of the aircraft with respect to an identified start point of the potential shortcut. Prior to the aircraft's arrival at the identified start point, current key performance indicators (KPI) of the shortcut are evaluated with the shortcut advisor tool. The aircrew is alerted to the potential shortcut along with a preview of the performance of the aircraft upon accepting the potential shortcut. The aircrew may accept the addition of the potential shortcut to the flight plan and request approval of the shortcut by air traffic control (ATC). The active flight plan is updated with the shortcut upon approval from the ATC.
