On another note:. Selecting where to point the nose when starting the descent is actually something one should think about carefully. The way I was taught its spin and pull, spin and pull, pull. Don't think just do.
But how much to spin the heading, and in which direction? I was flying along one day when I realised that if we were to turn left and start a descent we would fly straight into reciprocal traffic on an adjacent airway. It's not always so black and white. Shame they don't teach this procedure in more nuanced way.
