The implicit approximate factorization scheme known as AF2 is investigated for application to the solution of two- and three-dimensional transonic full potential equations in conservative form. The artificial viscosity used by different authors has been deduced, and is discussed in detail. A second-order correction to the implicit artificial viscosity is tested for transonic flow past a Korn aerofoil at both design and off-design conditions. The inviscid transonic flow past different aerofoils, wings, and wing-body configurations has been computed using the AF2 scheme, and the solutions are compared with experimental and other numerical results. It is shown that the AF2 scheme is fast, and is not sensitive to grid stretching
