An easily colored outer fabric is provided with a colored camouflage pattern and backed with a non-colored high tenacity fabric for enhanced durability. A colored intermediate adhesive is employed to maintain a camouflaged visual appearance without the added complexity of dying the high tenacity fibers of the backing material.

Abstract: Methods and systems are provided for indicating suggested or recommended diversion destinations with respect to segments of a planned route of travel. One exemplary method of presenting potential diversion airports for an aircraft involves identifying a flight path segment of a plurality of flight path segments between a departure location and a destination location based on a flight plan from the departure location to the destination location and identifying a subset of airports satisfying one or more filtering criteria with respect to the flight path segment. From among that subset, a recommended diversion airport is identified based on a viability ranking of the subset of airports with respect to the flight path segment and indication of the recommended diversion airport for the flight path segment is provided to a pilot or other user.
