4D FLY 对比 B4UFLY by FAA 的使用情况和统计数据

B4UFLY is the simple way for drone operators to check airspace and local advisories before taking flight. Stay compliant and contribute to safer national airspace by making yourself aware of advisories and restrictions in the airspace and local advisories around you. With B4UFLY, you simply open the app and select where you want to fly to see the status of the airspace selected, as well as details regarding surrounding advisories. B4UFLY is provided through a partnership between the FAA and Aloft (formerly Kittyhawk). Learn more at https://aloft.ai/b4ufly/ We have also added new crowdsourcing functionality for people to contribute to our global advisory and compliance database. You can flag areas for review and submit new locations for addition to B4UFLY advisories from within the app, or you can also visit this page to submit areas for review at https://aloft.ai/b4ufly-data-submission-form/.
