1. A flight trajectory system that estimates contaminant exposure experienced by a flight, comprising:
at least one input interface that is configured to receive at least one trajectory of a flight comprising flight track points;
a storage medium configured to contain instructions for executing a flight trajectory algorithm and a database of flight trajectory data; and
a computing arrangement coupled to the at least one input interface and the storage medium, wherein the computing arrangement receives the at least one trajectory of the flight and interrogates the database of flight trajectory data to:
validate the flight track points, wherein the flight track points are validated based on at least one performance of the flight,
generate a fixed trajectory for the flight based on the validated flight track points and the flight trajectory algorithm, by means of: interpolating latitudes and longitudes at (i) a flight track point without latitudes and longitudes and (ii) at least one gap in the at least one trajectory of the flight if the flight track point without latitudes and longitudes and the at least one gap in the at least one trajectory of the flight are detected,
interpolating altitudes at a flight track point without altitudes if the flight track point without altitudes is detected,
extrapolating take-off of the flight by modelling a beginning of the flight up to the first flight track point of the at least one trajectory or landing by modelling the end of the flight from the last flight track point of the at least one trajectory, if not available, and
analyze, using a flight trajectory model, the fixed trajectory of the flight to estimate contaminants exposure of the flight on the fixed trajectory, and wherein the contaminants comprise at least one of: dust, ice, atmospheric aerosol particles or corrosive gases.
