5.2) comparing related parameters in the image information source with a preset threshold, if the related parameters exceed the threshold, judging that the airplane parts observed from the point position have faults or potential safety hazards, and reporting to a crew through a management platform in time for maintenance;
and 5.3) if no fault or potential safety hazard exists, finishing the point location inspection maintenance work.
