1. A method for selecting a taxi exit on a runway for an aircraft that lands on the runway, the method comprising:
receiving historical data, wherein the historical data comprises:
historical runway data for a runway, wherein the historical runway data comprises:
a length of the runway,
a length and a location of a touch-down zone on the runway, and
locations of a plurality of taxi exits along the runway;
historical aircraft data for previous aircrafts that have landed on the runway, wherein the historical aircraft data comprises:
specification information of the previous aircrafts,
published aircraft performance data for the previous aircrafts,
speeds in the air of the previous aircrafts in a time period before landing,
elevations of the previous aircrafts in the time period before landing,
trajectories of the previous aircrafts in the time period before landing,
distances between the previous aircrafts and the runway in the time period before landing,
touch-down locations on the runway of the previous aircrafts,
displaced thresholds for the previous aircrafts,
decelerations on the runway of the previous aircrafts,
the taxi exits used by the previous aircrafts,
taxi times after landing of the previous aircrafts, and
fuel consumed after landing of the previous aircrafts;
historical weather data at a location of the runway; and
historical notice to air missions (NOTAMs) for the previous aircrafts, the runway, or both;
training a model using the historical data to produce a trained model;
receiving current pre-landing data for a current aircraft that is to land on the runway, wherein the current pre-landing data comprises:
current pre-landing aircraft data for the current aircraft, wherein the current pre-landing aircraft data comprises:
specification information of the current aircraft,
published aircraft performance data for the current aircraft,
a speed in the air of the current aircraft in the time period before landing,
an elevation of the current aircraft in the time period before landing,
a trajectory of the current aircraft in the time period before landing, and
a distance between the current aircraft and the runway in the time period before landing;
current weather data at the location of the runway; and
a current NOTAM for the current aircraft, the runway, or both;
determining, during the time period before landing, a feasibility of the plurality of taxi exits on the runway based at least partially upon the trained model and the current pre-landing data, wherein determining the taxi exit feasibility comprises dividing the plurality of taxi exits into at least a first group and a second group, wherein the current aircraft will either overshoot the first group of taxi exits or have to decelerate more than a predetermined deceleration threshold to access the first group of taxi exits if the current aircraft lands within the touch-down zone on the runway and does not have to turn around on the runway, and wherein the current aircraft will neither overshoot the second group of taxi exits nor have to decelerate more than the predetermined deceleration threshold to access the second group of taxi exits if the current aircraft lands within the touch-down zone on the runway and does not have to turn around on the runway;
determining a touch-down location for the current aircraft based at least partially upon the trained model, the current pre-landing data, and the feasibility;
receiving current post-landing data after the current aircraft lands on the runway, wherein the current post-landing data comprises:
current post-landing aircraft data for the current aircraft, wherein the current post-landing aircraft data comprises:
the touch-down location of the current aircraft on the runway; and
a speed of the current aircraft on the runway;
updating the feasibility during a time period after landing to produce an updated feasibility, wherein the updated feasibility is based at least partially upon the trained model, the current pre-landing data, and the current post-landing data; and
selecting one of the taxi exits in the second group based at least partially upon the updated feasibility.
