Comprehensive in both theoretical and numerical presentation. The authors show how to model invicid, incompressible aerodynamics using pnael methods which are based on potential theory. They also show how to incorporate viscosity inside the boundary layer. I found the book's detailed treatment of panel methods for unsteady aerodynamics particularly useful. Most textbooks only show the steady state case. The book is very practical with very good description of algorithms. At the end of the book, you can also find sample programs developed by authors' students.
