SofemaOnline (SOL) www.sofemaonline.com Considers Aspects of Aircraft Ground Icing & the potential for Performance Degradation.
Introduction - There is no such thing as an insignificant amount of ice.
As we understand any roughness on an aerodynamic surface (caused by ice, snow, or frost) is likely to disrupt the airflow over the lift and control surfaces of an aircraft.
Frost, ice, or snow formations on an aircraft may decrease the lift and alter the stall and handling characteristics. Aircraft may become airborne in ground effect but be unable to climb.
