Japan's "Asahi Shimbun" January 14 issue published a report entitled "The Government intends to strengthen the domestic drone company's assistance policy", said that small drones are being widely used in cargo transportation and other industries, the government decided to introduce assistance policies accordingly, Help domestic enterprises to develop or introduce drone models that can effectively respond to cyber-attacks.

It is reported that the Japanese government plans to submit a new bill at the general meeting of the parliament that opens on the 20th and strives to formally implement this summer.

At present, due to safety considerations, according to the provisions of the "Aeronautical Law" and other regulations, UAVs are restricted to fly around urban areas, nuclear power stations, and other important facilities and beyond the eyes of the operator. The Japanese government's policy is to relax some restrictions before 2022 to facilitate the use of drones in the logistics and security industries with severe shortages.

According to the report, with the popularization of 5G, mainstream drones may be capable of autonomous flight in the future, but there is also the possibility of being manipulated by third parties through hacking means or maliciously intercepting captured video images.

In order to prevent similar situations, the Japanese government will introduce a new law to provide support for aircraft models that have adopted security measures or for the introduction and development of autonomous flight systems. It is reported that when a venture capital company with a government background makes a capital contribution, it will relax some of the approval conditions and will also facilitate the relevant companies to obtain low-interest Japanese policy financial treasury financing.

The NAHB survey also found that while 20% of all home builders are likely to use drones over the next three years, 38% said it would not be possible to use drones at all. However, when drilling into the details, the builder's size comes into play again. Only 13% of builders started at less than 6 units, and they responded that they would use drones in the near future, while 41% of 100 units started or more said they would.
Across the construction industry, including the commercial and industrial sectors, the number of drones used is even more impressive. In fact, a report from the International Association of Self-Driving Vehicle Systems (AUVS I) in April found that the construction and infrastructure industry is one of the largest commercial users of drones.
AUVSI makes an assertion based on the Federal Aviation Administration's exemption data, which shows that the FAA has granted construction and infrastructure companies nearly 1,800 exemptions, accounting for nearly 60% of all industrial applications, and about 40 of the total 4,600 exemptions approved by the FAA. %. Allows companies to apply for FAA drone exemptions so that they do not have to meet the same airworthiness requirements as manned aircraft. The FAA expects to develop rules for drones this year.
In contrast to home builder drone usage figures, For ConstructionPros.com's analysis of AUVSI data found that almost all FAA exemptions issued to construction and infrastructure companies went to those with less than $ 1 million in revenue and less than 10 employees. Small business.
Drones have become a game-changing technology in the construction industry because they can monitor construction sites, take pictures, collect information, and then send it back to the project manager or design team.
