我想问的是，它不能按预期运行，是什么问题，即飞机必须走这条路。虽然我尝试了许多不同的方法，但是输出是意外的，请帮助。

您的错误是绘制Cap Lift的方式。应在svg画布的原点绘制路径，例如：<path d="M0,0 L100,0 100,20 0,20z"/>

在CSS中，我还注释了position: absolute;和z-index: 1;-在svg中无用

.FollowPath {
  fill: none;
  stroke: #ff0000;
  stroke-width: 4;
  stroke-miterlimit: 10;
  animation: draw 2s forwards infinite;
  stroke-dasharray: 936;
}

.Cap {
  fill: #000000;
  stroke: #000000;
  stroke-width: 1;
  stroke-miterlimit: 10;
  /*position: absolute;
  overflow: hidden;*/
}
.Lift {
  /*z-index: 1;*/
  animation: move 2s linear infinite;
  offset-path: path("M501.92,545.3c290.65-278.3,564.46-216.26,830,13.06");
}
@keyframes draw {
  from {
    stroke-dashoffset: 0;
  }
  to {
    stroke-dashoffset: -936;
  }
}

@keyframes move {
  from {
    offset-distance: 0%;
  }
  to {
    offset-distance: 100%;
  }
}

<svg viewBox="0 0 1920 1080" >
<path class="Cap Lift"
      d="M0,-10
         L100,-10 100,10 0,10z"/>
<path class="FollowPath" d="M501.92,545.3c290.65-278.3,564.46-216.26,830,13.06" />

在CSS SVG动画中，我无法对Á对象进行动画处理以遵循路径
