Methods and systems for performance based arrival and sequencing and spacing

A non-transitory computer-readable medium storing processor executable instructions, the medium comprising:

• instructions to receive flight parameter data relating to a plurality of flights in a processor in communication with a storage device including a probabilistic spacing advisory tool (PSAT) with a trajectory modeler and a spacing advisor, the flight parameter data including indications of aircraft performance based navigation (PBN) capabilities, a cleared or best available flight plan information, an aircraft configuration, and an airport configuration for the plurality of flights;
• instructions to assign probabilistic properties to the flight parameter data;
• instructions to receive accurate and current position and flight plan information from on-board avionics or from a ground-based monitoring and control system for a plurality of aircraft corresponding to the flight parameter data;
• instructions to determine a probabilistic trajectory for two of the plurality of aircraft based on a combination of the probabilistic properties of the flight parameter data and the position and predicted flight plan information, the probabilistic trajectory being specific to the two aircraft and including a target spacing specification to maintain a predetermined spacing between the two aircraft at a target location with a specified probability;
• and
• instructions to generate a record of the probabilistic trajectory for the two aircraft.
