This photo was taken on a recent flight from Adelaide to Pt Augusta. As you can see, it gets pretty cold at 20,000 feet, and on this occasion it was also very moist. The ice was forming all over the aeroplane, but built up particularly on the wing leading edges and the radome. You can see that the ice on the rubber leading edge has been cracked off by the de-ice boot, but it doesn't all come off. The propeller also picks up ice like this, and can get out of balance very quickly and send vibrations throughout the airframe. All in all, icing can be quite dangerous and we try to avoid it where possible. It's just nice to know that the aeroplane is capable of flying in these conditions....
