Why can`t helicopters go far from land?

Helicopters are designed to fly close to the ground and are limited in their range due to a variety of factors. The most significant of these is their relatively low maximum speed, which limits their ability to cover long distances. Additionally, helicopters are more affected by wind than other aircraft, and their range is further limited by the need to stay within the pilot's visual line of sight.
The primary reason helicopters cannot travel far from land is their relatively low maximum speed. The best helicopter speed record is held by a modified Sikorsky S-97 Raider, which achieved a maximum speed of 255 mph in 2019. This is significantly slower than the fastest fixed-wing aircraft, which can exceed 600 mph. The slower speed of helicopters means that they have a much shorter range than other aircraft.
Helicopters are also more affected by wind than other aircraft. Wind affects the speed and direction of helicopters, which can make it difficult to maintain a steady course. This makes it harder to cover long distances, as the pilot needs to constantly adjust their course and speed to account for the wind.
Finally, helicopters must stay within the pilot's visual line of sight. This means that they cannot fly too far away from land, as the pilot needs to be able to see where they are going. This limits the range of helicopters, as they cannot fly too far away from the pilot's point of view.
In summary, the primary reason helicopters cannot travel far from land is their relatively low maximum speed. Additionally, they are more affected by wind than other aircraft, and they must stay within the pilot's visual line of sight. These factors all limit the range of helicopters, making it difficult for them to cover long distances.

2. Mechanical Limitations: Helicopters can only operate within a certain range of airspeed, altitude, and wind conditions. These mechanical limitations limit the range of helicopters.
3. Weather Conditions: Inclement weather can reduce visibility and create turbulence, making it difficult for helicopters to fly safely.
4. Regulations: There are a variety of regulations that restrict how high and how far helicopters can fly. These regulations limit the range of helicopters.
5. Pilot Skill: The pilot's skill and experience level can also affect the range of a helicopter. Inexperienced pilots may struggle to fly in more challenging weather or terrain and thus limit their range.
