Would it help to have a little beeper thing that gets louder and higher the greater the g-force is above 1g?,(reply>), +FeepingCreature In order to avoid the graveyard spiral you need an instrument which tells you which way you're turning so that you can roll level. If you're flying in cloud there's nothing to see outside anyway, so your attention is focused on the turn and slip indicator or the artificial horizon. Also we already have an instrument which beeps at us to tell us whether we're climbing or sinking, so another would be quite distracting!
