A system comprising a program component that programs one or more non-volatile memory cells of an array of pairs of NVM cells using FN tunneling, an erase component that erases the one or more NVM cells of the array of pairs of NVM cells using FN tunneling, and a read component that reads the one or more NVM cells of the array of pairs of NVM cells. Herein, the plugs are positioned beneath the first and second fuse boxes. Once the user has input the parameters, an aerodynamic coefficients generator module included with the flight simulation program determines aerodynamic coefficients for the aircraft design, using classical formulas and determining the coefficients in an appropriate order.
