Jumbangla Desk: There are two altitude limits for private helicopter service providers. The Civil Aviation Authority (CABA) has two runways at 500 and 1,000 feet from the ground. While there is an obligation to fly drones, remotely piloted aircraft systems, remote controlled toy aircraft in this border without permission, it is not allowed to fly kites. In many cases, kites are flown at heights of up to one and a half thousand feet using long strings. As a result, kite strings often get stuck in flying helicopters. There is a fear of a major accident.
According to international rules, there are restrictions on flying kites above 60 meters or 200 feet. There is also a ban on flying kites within three nautical miles of the airport. Although these are not accepted in the country. Especially around Hazrat Shahjalal International Airport i.e. kites flying using long strings from Gazipur, Purbachal and Ashuganj are creating more risk in helicopter traffic. Although no major accidents have occurred so far, the private helicopters are often facing mechanical damage.
In this context, the director of the flight operations department of the private helicopter service company South Asian Airlines and the chief pilot squadron leader Gulzar Hossain told Barta that 500 and 1000 feet are allocated for private helicopters, but 500 feet is used in most cases. In the past, kite flying was limited to a maximum range of 300 feet, but in recent times, many competitors use long strings to fly kites up to 1,500 feet in airspace, which is dangerous for helicopter flights. Plastic strings are being used instead of ordinary strings for flying kites, which are so tough that they tear and twist when they come into contact with helicopter blades, posing a serious risk to safe flying.
He said, although kites are flown throughout the year in our country, this trend increases after monsoon. Initiatives should be taken to increase awareness among the common people before major accidents occur.
According to the investigation, plastic kites have replaced paper kites. And the plastic thread that is being used instead of the ordinary thread for flying the kite is also being strengthened by mixing glass, iron and aluminum powder with glue. By mixing these materials, the yarn becomes so strong that it cannot be torn easily even by pulling. If the helicopter’s fan is twisted, pulling the kite thread and untying it creates many problems. In many cases there are mechanical errors.
A senior official of the flight safety department of Babychock, the private helicopter service regulatory body, said that the ‘Civil Aviation Authority Bill-2017’ has been passed to control any flying device including drones, gliders. Flying kites uncontrollably around airports is a punishable offense as it poses a risk to helicopters operating in the airspace. But it is difficult for the baby to control it. That is why those who fly kites using long strings around the airport should be aware. At the same time, awareness about the risk of accidents should be increased.
Note that a press release of Inter-Services Public Relations (ISPR) has also warned about flying kites. According to the 2020 notification, permission will be required to fly drones, remotely piloted aircraft systems, remote controlled toy airplanes and kites. Flying them without authorization is considered a risk to national security. As a result of flying without authorization, domestic and foreign regular passenger aircraft, helicopters and
High-speed military aircraft are prone to sudden crashes. ISPR said in a notification at the time that flying anything without authorization considering the risk to national security would be considered a punishable offence.
The little girl hugged the ostrich’s neck, then what will happen
According to Babychak sources, 30 helicopters of 10 companies are currently providing commercial services in the country. Apart from this, they are also used for personal purposes. Among them, three helicopters of Square Limited, four of Meghna Aviation, seven of R&R Aviation, four of South Asian Airlines, four of Bashundhara Airways, one of Impress Aviation, two of BRB Air Limited, one of Bangla International Airlines, two each of Pertex Aviation and BCL are being used commercially. . According to Bebichak’s calculations, a few years ago the number of helicopter flights per month was about 1,000, but now more than 5,000 flights are being operated per month.
