The direction she faces is controlled by pushing the appropriate pedal. If the helicopter drifts forward she moves the cyclic stick rearward a bit to counter the drift, if it drifts right moves the cyclic left, etc. When everything is perfectly balanced our pilot can quit moving the controls and the helicopter will stay motionless in a 10 foot hover. This lasts for maybe a second. On a good day.
Helicopters are inherently unstable.
Throw in the push of the invisible wind and they get worse. So our pilot starts to move her flight controls again, hands and feet together, coordinated and smoothly, precisely and timely. The helicopter will drift no more than a couple of inches in the air in any direction. If our pilot is not very proficient or if the wind is gusting she will move the controls an inch or two. The helicopter will drift a foot in any direction.
