The first viscous compressible three-dimensional BiGlobal linear instability analysis of leading-edge boundary layer flow has been performed. Results have been obtained by independent application of asymptotic analysis and numerical solution of the appropriate partial-differential eigenvalue problem. It has been shown that the classification of three-dimensional linear instabilities of the related incompressible flow [13] into symmetric and antisymmetric mode expansions in the chordwise coordinate persists for compressible, subsonic flow-regime at sufficiently large Reynolds numbers.
