AEDsys - Aircraft Engine Design System Analysis Software. This program calculates the performance constraints (wing loading versus thrust loading) and aircraft system performance plots (contour plots) in support of Chapters 2, 5-7 in Aircraft Engine Design, Second Edition; and the fuel use and aircraft performance in support of Chapters 3 through 7 in Aircraft Engine Design, Second Edition. This program includes the off-design analysis of gas turbine engines (previously contained in OFFX) to predict engine performance. It is written in Visual Basic 6 with user input menus and data fields
