From Elite Simulation Solutions AG:
ELITE's precise aerodynamic flight modeling assures that each aircraft's flight characteristics are predictable and expected. You shouldn't have to divert your attention by reacting to unexpected flight characteristics when you have other tasks to focus on. That is why ELITE has painstakingly made every effort to create the most accurate flight models available. ELITE combines aircraft known "book" data with data collected from actual aircraft flight tests to form the foundation of each flight model. The lengthy design process yields an acceptable flight model algorithm (the software instructions that define how the aircraft flies) only after numerous cycles of testing, refinement, and re-testing. After all, the aircraft should fly like an aircraft. You'll find no surprises here.
