  3. After landing, the plane is placed on a horizontal plane, and the horizon seen in the hud has a tilt ranging from 0.01 to 0.07, but at this time the plane is physically level
  4. After a while (the time is not fixed), the ground plane starts to move in an inclined direction in the hud. When it reaches a certain position, it triggers: ekf3 imu0 forced reset; At this point, hud returns to a horizontal position
