Er no Ols500, the standard cold and dark is not fine, in the RW if you come on board an A/C with the emergency lights in the armed position and gated the A/C would be grounded until all the emergency light batteries had been changed, the A and B elec. Hyd switches are never left in the on position because if somebody powered the A/C without checking all sorts of things could move, e.g. the steering, a bloke at Gatwick had his leg smashed because of this!!
