Abstract
An evacuation assembly of an aircraft includes an evacuation slide and a sheet coupled to the evacuation slide. The sheet may be deployable in a wind curtain configuration and a canopy configuration. In the wind curtain configuration, the sheet may extend, as a substantially vertical panel, longitudinally along opposing lateral sides of the evacuation slide. In the canopy configuration the sheet may extend over at least a portion of a top side of the evacuation slide. In the canopy configuration, the sheet may include a first portion that is the substantially vertical panel that extends longitudinally along the opposing lateral sides of the evacuation slide and a second portion that extends over the top side of the evacuation slide. The second portion of the curtain may in a furled, collapsed form in the wind curtain configuration and may be configured to unfurl in the canopy configuration.
