BPF - the problem with looking out at the nose is that often an engine failure in a twin is given under IR training and hence the stud is behind screens. I always used to use 'Dead leg, dead engine'.
But I agree with your general point that too many 'sayings' can obscure the picture.
One that that I remember from training 'Fly the aeroplane......!' So "aviate-navigate-communicate" always a good one to keep in mind.
