Two advantages of helicopter services over aeroplane services are-
- Helicopters can hover, land and take off in a vertical position due to its small size. Aeroplanes cannot do that.
- Helicopter service provides site-seeing for the tourists and offer a wide variety of services including flying ambulances to hold patients, assistance in loading water to fight giant fires.
One disadvantage of helicopter services over aeroplane services is that the noise and vibration might cause nausea, pain and motor dysfunction in the passengers. The comfort level is less as compared to an aeroplane.
