Ok - put your hands up if you have done an auto at night to the hover - on an airfield where everything is level and clear.
Now keep your hands up if you have done an auto to the hover off airfield.
Anyone scared themselves sh*tless yet?
Now imagine it happening at an unplanned moment where you have to select a suitable landing area in the dark AND THEN carry out an EOL you can walk away from.
Does anyone still not get why it is more risky at night???
