I want to know the answer to the following question:
What capability do helicopters use to move over the flight deck and land vertically?
All the background I'm provided with is that "The arrested-recovery system has used an angled deck since the 1950s because, in case the aircraft does not catch the arresting wire, the short deck allows easier take off by reducing the number of objects between the aircraft and the end of the runway.". Is that enough to answer the question?
Answer: no
