All modern planes (and this one is only a year old) have some ability to de-ice while in the air - whether by heating or even using inflatable devices which break the ice around key components. Ice can build up very quickly as planes pass through different layers in the atmosphere.
For anyone who lives in a cold climate, go wash your car on a day when it is below freezing and then don't dry it. See how fast your locks and wipers freeze up? Magnify that by a factor of ten and that's what airplanes have to deal with.
