When can a pilot operate a RPAS according to CAR regulations regarding icing conditions?

Operating a Remotely Piloted Aircraft System (RPAS) in icing conditions is highly regulated due to safety concerns. The correct choice highlights that a pilot is permitted to operate an RPAS when equipped with anti-icing equipment. This is because anti-icing systems are specifically designed to prevent ice accumulation on the aircraft's critical surfaces, ensuring control and stability during flight.

The presence of ice can significantly impact an aircraft's performance, leading to reduced lift, increased drag, and potential loss of control. Therefore, regulations mandate that unless a drone is equipped with appropriate anti-icing or de-icing systems, it should not be operated in such conditions to mitigate the risks associated with icing. This choice reflects a crucial understanding within aviation safety about the importance of proper equipment in potentially hazardous weather conditions.
