Method and system for determining aircraft landing runway conditions

An airport manager system for determining aircraft landing runway conditions, the airport manager system comprising at least one processor, wherein the at least one processor is adapted to:

• acquire a set of data groups of different types for evaluating and monitoring deteriorating runway conditions of a runway, wherein a first data group of the set of data groups is acquired from a first source and a second data group of the set of data groups is acquired from a second source different from the first source;
• determine weighting coefficients to each data group;
• filtering the data of the set of data groups;
• determine, for each data group, a partial runway condition for a sector of the runway based on the filtered data;
• modify the weighting coefficients of each data group after filtering the data;
• and
• generate (i) a runway coefficient for the sector of the runway by combining the partial runway conditions and (ii) a confidence index associated with the runway coefficient, wherein the confidence index is derived from the modified weighting coefficients.
