Limited Artificial and Natural Icing Tests of the External Stores Support System (ESSS) Installed on a UH-60A Aircraft.
A limited artificial and natural icing evaluation of the production UH-60A Black Hawk helicopter equipped with an External Stores Support System (ESSS) and selected components of a prototype Wire Strike Protection System (WSPS) was conducted to determine the capability to operate safely in a moderat...
