The world's bestselling drone-maker has unveiled models that warn their operators when there is a risk posed by nearby aeroplanes or helicopters, BBC reports. 

The M200 series use ADS-B (automatic dependent surveillance broadcast) receivers to detect broadcasts from nearby manned flights.

The transmissions allow users to see the position, altitude and velocity of surrounding aircraft so they can take evasive action if required.

One expert praised the move.

"It's an extra safety measure and will help drone operators work in restricted airspace," explained Dave Black from the commercial drone services firm Blackwing Aerial.

"The way we tend to do this is to contact air traffic controllers before we fly, tell them where we are flying and then they contact us by phone if there's going to be any conflict.
