The invention relates to a landing safety event prediction method and
system based on QAR data and multi-
task learning, and belongs to the technical field of
aviation flight safety. The method specifically comprises the following steps: S1,
processing multi-parameter QAR data through a multi-scale sharing
encoder; s2, performing task specific parameter
weight distribution on the shared unified feature representation through a parameter selector; s3, performing time dependence modeling on the task related features through a
time sequence decoder; and S4, utilizing a multi-task
loss function to jointly optimize the prediction tasks of the plurality of security events. The technical scheme of the invention can be used for simultaneously predicting various safety events in a flight landing stage, such as a
tail wiping event and a hard landing event, and a
flight safety guarantee tool is provided for an airline company; through
deep mining of potential association between
flight data and different safety events,
pilot training and operation processes are optimized, and
flight safety standards are improved.
