Slope landings are a normal everyday part of helicopter operations for most pilots and over time you will get to the point that you will enjoy doing them. The real trick to doing them successfully is to pick the slightest angle possible....and if it is not comfortable to you...find a more level place....even if it means refusing to do the required task. Always fly within your levels of comfort....as you gain experience those levels widen. I might suggest that you include slope landings more often than the one time a year you are tested on them. In time....it becomes a piece of cake....especially after you escape from flying Robbies.
