Title:
METHOD AND SYSTEM FOR MEASURING IN-FLIGHT LANDING DISTANCE
Document Type and Number:
WIPO Patent Application WO/2022/257620
Kind Code:
A1
Abstract:
A method and system for measuring an in-flight landing distance. The method comprises: performing, on parameters, which are related to the measurement of an in-flight landing distance, in each flight of each of aircrafts of different types, parsing and decoding, big data writing, and matching and association with flight information in a flight operation system, and establishing a relationship matching table of flight data and flight information (step 1); creating a static data table of glide path data of an airport runway, storing same in a big data environment, performing, by means of taking a landing runway in a landing airport as a data primary key, matching and association on the static data table of the glide path data of the airport runway and the relationship matching table, and constructing a flight information dynamic table that includes the glide path data (step 2); performing normalization processing on the parameters (step 3); and on the basis of the distances from glide paths in different runways of different airports to runway thresholds, and glide angles, measuring the horizontal distances from the runway entrances to a ground point (step 4). By means of the method, the calculation precision of an in-flight landing distance is improved, and the effects of monitoring the control quality of a pilot and assessing civil aviation safety risks are improved.
