The helicopter is more advantageous in terms of takeoffs or landings because it does not need a large place like an ordinary aircraft but on the one hand, the helicopter had problems with takeoffs or landings where the place should be flat.
DARPA has just demonstrated a helicopter that has been modified its leg with the robotic landing gear in an unmanned flight near Atlanta, Georgia, that's designed to overcome these limitations by enabling landings on broken or uneven terrain with a high degree of safety.
