SARcastic seems to be dangerously unaware of the dangers of night hovering. Autohover and height hold are very good but not infallible. A good friend of mine was nearly drowned in a FULLY COUPLED fully serviceable Coastguard S61N which ditched, I believe, due to loss of spatial awareness at night. He was washed into the tail and only managed to get out when the rear escape door was opened from the outside. AllyPally is right, you have to have the skill to fly the aircraft when the automatics fail/throw a wobbly. Writing notes in the Autohover is not a good idea unless you are totally unaware of what can go wrong.
