Why and why not

机场附近注意事项
一般在1公里之内没有住房。10公里内没有高楼住房，10公里范围内不超过30米，20公里范围内不超过150米。
机场净空保护区是指为保障航空器在机场安全起飞和降落，按照机场净空障碍物限制图的要求划设的一定空间范围，保证在飞机的起飞和降落的低高度飞行时不能有地面的障碍物来妨碍导航和飞行。现在的风筝、航模、无人机等升空物体制作工艺先进，很容易飞到几百米甚至上千米的高空，这些东西一旦被吸入飞机发动机，很可能造成飞机发动机空中停车或者仪表指示故障，严重的会是飞机损失升力，造成飞行安全事故；另外，燃放烟花爆竹产生的光线和浓烈烟雾，容易影响到机场区域的能见度，对飞行员准确判断跑道位置产生干扰。
