1. The simulated aircraft was a Boeing 747. The f l i g h t equations were based on References 10 to 12. The aerodynamic forces and moments were obtained from Reference 11 and stored i n the form of lookup tables. The equations were solved using a 2nd order Adams-Bashforth numerical integration scheme. A f u l l set o f ground handling equations was developed as well, along with a JT90-3 engine model derived from Reference 11. Navigation and Landing Aids
