Final answer:
One type of weather phenomenon that may concern remote pilots associated with cold fronts is turbulence.
Step-by-step explanation:
One type of weather phenomenon that may concern remote pilots associated with cold fronts is turbulence. Cold fronts are known for creating significant temperature differences along the frontal boundary. As the colder air mass interacts with a warmer air mass, it can lead to the formation of turbulent conditions, including gusty winds, vertical air currents, and turbulence pockets. These turbulent conditions can be hazardous for remote pilots and may require adjustments to flight plans and altitude.
