大家知道,作为航空器,空中是它展示才华最主要的舞台。在空中它们各显其能、尽展英姿。然而航空器在地面活动的情况如何,可能许多人都不太了解。例如,直升机在机场,允许以1米以下飞行高度进行调度,航空器需要用牵引车来移动位置等。但是在更多的情况下,滑行是航空器在地面活动最主要的方式。 We all know that as an aircraft, the air is the most important stage for its display of talent. In the air they each show their ability to make their best. However, the situation of an aircraft operating on the ground may not be well understood by many people. For example, a helicopter at an airport allows for scheduling at flight altitudes up to 1 meter, an aircraft needs a tractor to move a position, and the like. However, in more cases, taxiing is the most important way for an aircraft to move on the ground.
