示例： This is a picture about runway excursion. On the top of the picture, the sky is overcast, visibility is poor, and it's not a good day for flying. In the middle of the picture, there is a multi - engine aircraft in the water near the runway, having gone off the runway. At the bottom of the picture, I can see the blue water. On the left side of the picture, there are airport buildings, runways, and other aircraft parked. On the right side, there's more water and a small boat nearby. Runway excursions can be dangerous, so pilots must undergo thorough training to handle such situations. 这是一张关于跑道偏离的图片。 在图片的上部，天空阴沉，能见度差，不是适合飞行的好天气。 在图片的中部，有一架多引擎飞机在跑道附近的水中，已经偏离了跑道。 在图片的下部，我能看到蓝色的水。 在图片的左侧，有机场建筑、跑道以及停放的其他飞机。 在右侧，有更多的水，附近还有一艘小船。 跑道偏离可能很危险，所以飞行员必须接受全面的训练来应对这类情况。
