The pilot’s spatial orientation, the same as the one of any other human, relies on a combination of stimuli coming from their audio-visual, vestibular and proprioceptive perception systems. However, these instinctive perceptual methods can easily fail while pilot is perceiving real changes of attitude, position or movement and they can also generate false illusions to each of the aforementioned parameters. This failure in a real flight is called “flight illusion” which can negatively affect the pilot’s spatial orientation. The influence of a flight illusion on the pilot’s spatial orientation can be assessed either subjectively or objectively. The aim of this paper is to demonstrate one of the possible objective assessments of the flight illusions influence on the pilot’s spatial orientation using the flight data generated by an appropriate flight simulator which were analysed in MATLAB® software. The chosen method is based on a comparison of the digitalized standard instrument flight trajectories with the real flown trajectories in the time interval with potential flight illusion influence.
