A biometric computing system obtains, via an inertial sensor, time-based inertial measurement data with respect to a human subject located on-board an aircraft for each of a plurality of on-board sessions with one or more aircraft. The time-based inertial measurement data may be transformed for each on-board session to a common reference frame that is shared by the plurality of on-board sessions. The transformed data of the plurality of on-board sessions are combined to obtain a time-based inertial measurement profile for the human subject. The biometric computing system further obtains, via a range of motion sensor, force-based range of motion measurement data with respect to the human subject interacting with a physiological measurement device across a range of motion. The force-based range of motion measurement data is combined with the time-based inertial measurement profile for the human subject to obtain a combined measurement profile for the human subject.
