Use real-world reference data (flight manuals and Type Certificate Data Sheets) to calculate accurate results for flight simulations and for instructional content in Ground School Training Programs.

Weight And Balance Includes:

Weight And Balance Settings (Widgets)

  • Data table workflow which allows the development through the settings of the principle data tables with multiple aircraft selection and profiling of weight and balance data.
  • Item weight settings.
  • Center Of Gravity Calculations (Displayed and Back-end Data): Total Weight, Total Moments, Longitudinal CG Arm, Percent MAC, Forward CG Arm Limitation, Aft CG Arm Limitation, Over Max Weight State, Outside CG Limits State, Category Number, Category, Payload Weight Data, Fuel Weight Data, and Oil Weight Data.
  • Automatic transfer of CG data to the player pawn.
  • Center Of Gravity Visualization: visualization of the center of gravity location, forward limitation, and aft limitation in relation to the Mean Aerodynamic Chord (0% MAC to 100% MAC). Forward and aft limit bars provide color indications of the CG state.

Longitudinal Stability Demonstration (Map, Blueprints, And Widgets)

  • Demonstrates the implementation of the transferred CG calculations and simulates the principle effects of weight distribution on the longitudinal (pitch) stability of the aircraft.
  • Demo fixed wing aircraft data: Trainer, Acrobatic, and Commuter.
  • Control Panel: Pitch Trim, Airspeed, Center Of Lift, and Center Of Gravity Scale.
  • Pitch Attitude Indicator.
