Visual Integrated Portable Environment for Rehearsal in 3-D
Viper 3-D Logo
VIPER 3-D is a portable 3-D environment that provides aircrews the ability to preview and, if necessary, re-plan their mission.  

VIPER 3-D allows mission data such as routes, threats, and airspaces to be displayed over 3-D terrain made of real world imagery and elevation data.  Data is pulled directly from the Portable Flight Planning System (PFPS).
