What is the advantages of helicopter?
The biggest advantage is being able to land and take-off in a very small space. This is very useful in cases like operating off warships where they may land on a very small and moving space on the rear deck.
There are numerous advantages to a Black Hawk helicopter. The first is that it is durable as sh*t. It will get you where you need to go(not speaking about comfort here). It can also be transformed so that the injured and wounded can be attended inside the aircraft. Lastly, it gets troops and supplies in and out and it has a great track record and has been around for quite a while.
Helicopters tilt to offset the direction of their lift in order to initiate movement in that direction. A helicopter pilot can tip the helicopter forward to get a little forward motion, and then tip the helicopter back to stop or even reverse. Likewise, the pilot can make the helicopter "slew" left or right by tilting the helicopter left or right.
