A bill introduced in the Senate this week would require drone operators to prove they understand aviation regulations. The bill would set policy for the Federal Aviation Administration and includes a requirement for unmanned fliers to pass an online test. The measure is one of the several provisions designed to improve drone safety following many reports of unmanned aircraft flying too close to traditional planes and helicopters, according to Bloomberg. The bill would also beef up the FAA’s enforcement of violations, require safety features and fund programs to intercept drones near airports. The FAA started requiring operators to register with the federal agency this year, but there is no testing required currently. Unmanned aerial vehicles have many uses for farming and industry leaders say agriculture represents the largest sector of growth for the technology.
