Ice Ridges on the Lower Nose Fuselage

With the start of the winter season in the northern hemisphere, it is a timely reminder to re-publish this Airbus article, initially written in 2018. Ice ridges on the lower nose fuselage can cause Computed Airspeed (CAS) values delivered by the ADRs to be lower than the actual airspeed which may lead to unreliable airspeed events. This article describes the potential effect on the aircraft’s systems from the takeoff phase and how to prevent such a situation.
