In the event of ice accumulation, what is the first step pilots should take?

When dealing with ice accumulation on the SkyWest CRJ 200, the first step pilots should take is to activate anti-ice procedures. This action is essential because ice can significantly impact the performance and handling characteristics of the aircraft. By initiating anti-ice procedures, pilots can prevent or mitigate the effects of ice buildup on critical flight surfaces, ensuring that the aircraft maintains its aerodynamic properties and control responsiveness.

Delaying action until landing can lead to an unsafe condition, as ice accumulation during flight can worsen and affect the aircraft's performance. Alerting air traffic control can be necessary in some situations, but it should not be the first step taken to address ice accumulation. Reducing engine power doesn't directly relate to managing ice and could actually exacerbate performance issues in ice-affected conditions. Therefore, activating anti-ice procedures is the correct and most effective response to ensure safety in the presence of ice accumulation.
