What should a pilot do if they suspect icing in flight but temperatures indicate it's above freezing?

Activating de-icing systems is the appropriate action a pilot should take if they suspect icing in flight, even if the temperature indicates it's above freezing. This is because certain conditions, such as supercooled water droplets, can exist in clouds or precipitation at temperatures above freezing, which can lead to ice accumulation on the aircraft.

Utilizing de-icing systems helps prevent ice buildup that can adversely affect flight performance, control, and safety. It’s crucial for pilots to remain proactive in managing the risk of icing regardless of temperature readings to ensure safe flight operations.

While reassessing the approach and altitude or consulting with ATC could provide additional safety measures, the immediate and most effective response to a suspicion of icing is to engage the de-icing systems to mitigate the potential risk. Ignoring the conditions is not advisable, as it could lead to dangerous flight situations if ice does start to accumulate.
