Visual FPM



Visual FPM (vFPM)—Westar’s Second-Generation Technology


The FPM (Flight Performance Module) provides an electronic representation of an aircraft’s capabilities and limitations.  The FPM is used by a mission planning system to compute an aircraft’s ability to execute a mission.  vFPM is Westar’s second-generation FPM development tool and runtime engine.

vFPM reduces life-cycle costs through:

  • enhanced developmental tools
  • automated engineering processes
  • improved maintainability
  • simplified testability
  • extended platform support


The user benefits from reduced computation times.

Similar FPM datasets (derived from flight test data, engineering data, digitized performance charts) support various hardware platforms and operating systems to include Windows-based kneeboard, hand-held, on-board, and other emerging architectures.

These datasets also may have a reduced set of functionality (sub-setting) and/or functionality overrides (substitution). Sub-setting allows for minimizing the FPM to the functionality required for a specific platform or application while providing the same result as the “complete” desktop mission planning FPM. Substitution enables approximating functions to replace iterative solutions that can not be tolerated on a time critical system (embedded). This provides a result within the time tolerance defined at FPM design.
