We present a basic althought little known numerical stability condition: for convection equations, the von Neumann stability constraint ∥un + 1∥L2 ≤ (1 + C   Δt) ∥un∥L2 drives to the stability condition Δt ≤ CΔxα with where p is an integer linked to the stability domain of the time scheme and q ≥ p an integer linked to the upwind property of the space discretization (in the centered case we have q =  +∞ and ).
