Not everyone needs a certificate to fly a drone; if a drone weighs less than 7 kg, if it is flown indoors or in sparsely 2 populated areas, then a certificate is not required, the AOPA says.
AOPA表示，并非所有人都需考证才能操控无人机。操控7公斤以下无人机，在室内或非人口稠密区操控无人机，则不必考证。
Drones are still risky 3, and can be dangerous if flown with inexperience, in a bad weather, or illegally.
无人机仍旧是具有风险的，如果飞行经验不足，或是天气恶劣，又或是非法飞行就会非常危险。
