Take all practicable steps to minimise hazards to persons, property and other aircraft (i.e. don’t do anything hazardous)

The Pilot in Command is responsible for the safety of the flight.

To achieve this the drone must not create a hazard to people, property, or other aircraft.

This is a very broad ‘rule’ and has a lot of aspects to look at to achieve compliance. Interaction with people to ensure you do not create a hazard to them, consent to operate in the area you are in, hazard identification of the area to ensure no harm can be made to vehicles, buildings, stock etc. Permission from Air Traffic Control if required, and even with permission, maintaining a watch for other aircraft and abiding by the clearance ATC has given to you.

A useful method to ensure you have covered all aspects of potential hazards before beginning the flight is to use a checklist or a hazard identification process. You can then be confident the likelihood of creating a hazard is low and you’ve ensured you have taken all practicable steps to minimise hazards, as per the rule 101.13(1)
