Do not look down…biggest problem is folks focusing their eyes too close to the helicopter.
Look towards the horizon, do not focus too intently on one spot, you will get tunnel vision, let your peripheral vision do its job.
i always remember my instructor, after returning the helicopter to a state of equilibrium..placing one middle finger on top of the cyclic the other on the end of the cyclic and the toes of his boots lightly on the pedals and doing a perfect hover pattern with a 360 at each corner and saying…”yer making it much more difficult for yourself than it really is….now relax!”
Oh….hover hand relaxation device….a cigarette works even better.
