## Abstract

Techniques for assessing an operational condition of an uncrewed air transport platform are presented. The techniques include: arranging the uncrewed air transport platform and at least one external sensor in proximity to each other, where the at least one external sensor includes a vibration sensor; executing a sequence of operations of the uncrewed air transport platform; acquiring sensor data of the uncrewed air transport platform from the at least one external sensor; automatically analyzing the sensor data to detect at least one non-normal health signature of the uncrewed air transport platform; automatically diagnosing one or more degradation condition in the uncrewed air transport platform based on the at least one non-normal health signature; and providing an indication of the one or more degradation condition.
