Abstract
The purpose of this article is to investigate the barrier ice accretion after aircraft de-icing, as well as to analyze the impact of it on flight safety. The influence degree of the flight speed factor, the factor of the ice ridges location relative to the aircraft Pitot tubes on the airflow disturbance creation and the total pressure indicators pulsations is studied. It was analyzed the aviation accidents related to the aircraft icing process. A detailed study of the incident caused by the barrier ice in the fuselage nose section was performed; weather conditions and de-icing procedure by the ground personnel were analyzed. It has been presented a picture of the turbulent flow pulsations behind the ice ridges, making it possible to determine the flight conditions when the crew may receive unreliable information about the airspeed being an important parameter necessary for the autopilot normal operation.
