航向/航迹垂直速度/飞行路径角度切换

The HDG/TRK VS/FPA button switches between a heading and vertical speed reference (where the nose is pointing at and how fast you climb or descent) over to a track and flight path angle reference (where you're actually flying with the wind and at what angle you climb or descent).

The TRK+FPA mode is useful during an approach where you have a bit of crosswind and instead of calculating how much you need to point the nose into the wind to fly where you want to, you just tell the autopilot where you want to fly to in track mode. It automatically compensates the cross wind and keeps the aircraft flying in the same direction.

HDG / TRK VS / FPA按钮可在航向和垂直速度参考(鼻子指向以及您爬升或下降的速度)之间切换到轨迹和飞行路径角度参考(实际上是随风飞行的位置)以及您攀登或下降的角度)。

TRK + FPA模式在有一点侧风的情况下非常有用，您无需告诉自动驾驶仪您想飞向何处，而是计算出将鼻子对准风向飞行所需的飞行距离在跟踪模式下。它会自动补偿侧风并保持飞机向同一方向飞行。(现在MSFS 2020这个按钮并没有启用)
