FAA released beta version of B4UFLY smartphone application for testing by up to 1,000 unmanned aircraft users. Aimed primarily at model aircraft enthusiasts, app gives users information about restrictions or requirements in effect at their current or planned flight location. Status indicator function considers airspace, proximity to airports, temporary flight restrictions, and current law. FAA expects beta test will yield valuable data on how well B4UFLY functions and uncover any software bugs.
