Embodiment 1
[0057] This embodiment provides a flight trajectory optimization method based on dynamic sampling;
[0058] Such as Figure 7 As shown, the flight trajectory optimization method based on dynamic sampling includes:
[0059] S101: Obtain the data of the airborne quick access recorder QAR; create an empty array L, and sample and record data idx=0;
[0060] S102: Load the data of the quick access recorder QAR one by one in chronological order;
[0061] S103: Determine whether the ground speed at the current time point is greater than the first set threshold; if yes, enter S104, if not, return to S102;
[0062] S104: Determine whether the difference between the heading in the previous second and the heading at the current time point is greater than the second set threshold; if yes, go to S105; if not, go back to S102; add one to the sampling record data idx;
[0063] S105: judge whether the sampling record data idx is a multiple of the third set threshold, if yes, record the lat...
Embodiment 2
[0081] This embodiment provides a flight trajectory optimization system based on dynamic sampling;
[0082] Flight trajectory optimization system based on dynamic sampling, including:
[0083] The acquisition module is configured to: acquire the data of the airborne quick access recorder QAR; establish an empty array L, and sample and record data idx=0;
