A case study of high sea salt aerosol (SSA) concentrations as a hazard to aviation

Abstract

Abstract: On the night of 2nd January 2014 an aircraft on approach to Cork airport was required to abort a landing attempt due to sea salt aerosol (SSA) accretion on the windscreen. The salt reduced forward facing visibility to dangerously low levels. This was the first time such an incident was recorded by Irelands Air Accident Investigation Unit. This paper describes the meteorological conditions at the time of the aborted landing approach. Sea salt aerosol formation mechanisms are elaborated as is the relationship between SSA concentration enhancement and meteorological variables. A brief comparison between the meteorological conditions surrounding this and another notable event documented by the US naval service is made. The potential for SSA to be a significant hazard to aviation is considered as are recommendations for further research.
