Since : ArcGIS API for Flex 2.0

Helps you find service areas around any location on a network. A network service area is a region that encompasses all accessible streets (that is, streets that are within a specified impedance). For instance, the 5-minute service area for a point includes all the streets that can be reached within five minutes from that point.

Note: ServiceAreaTask, and other service area related classes, requires ArcGIS Server 10.0 or above and a "service area" layer. A "service area" layer is a layer of type "esriNAServerServiceAreaLayer".
