垂直偏离指示（Vertical deviation indication，VDEV） 垂直偏离指的是飞机在进近时偏离了FMGC计算好的垂直航迹参数的情况。 VDEV在A320客机PFD中有两个版本：一种是只带点的VDEV标志，另一种是带有点和标尺的VDEV表。

2023年8月16日 · One important aspect of flying the A320 is understanding the concept of Vertical Deviation (V/DEV). V/DEV refers to the difference in altitude between the aircraft’s actual position and its intended altitude. In this article, we will explore what V/DEV is, its significance in aircraft operations, and how it is managed on the Airbus A320.

2007年11月15日 · "Upon reaching TOD and down to final approach guidance a magenta VDEV symbol is displayed. It indicates the aircraft vertical position in relation to the FMGC vertical profile". So my question is, does it just act basically like

2015年12月6日 · vdev is vertical guidance in a range of descent & approach modes. if you select an NPA approach in the FMGS / MCDU (ie not an ILS approach), and after the approach phase is activated (either manually or automatically), VDEV (the brick) is shown beside the PFD vertical altitude ladder for vertical guidance ... in both managed & selected modes.

1.在rnav进近中只出现了L/DEV 未出现V/DEV应怎么解决？ 5 用来增加进近速度提升飞机机动性，比如天气不好或者有故障的时候。 注意打开顶板上的land config 3. 关于A320的一些疑..最近在飞FBWA3201.在rnav进近中只出现了L/DEV 未出现V/DEV应怎么解决？ 2.跑道有积水或正在下大雨或预计起飞后会遇到大雨或颠簸的情况下 发动机模式选择器选择点火 什.

ALT CST* guides the aircraft to acquire an altitude constraint provided by Flight Management. Once the aircraft has reached the altitude, the altitude mode (ALT or ALT CST) engages. The mode engages when the aircraft reaches the altitude capture zone, defined by the aircraft vertical speed (among other parameters).

2018年1月2日 · Remember, the VDEV is not going to be very useful unless you are getting down to your final altitude at high speed & decelerating from that point. If you are configuring your aircraft earlier due to an ATC speed limitation and trying to keep a continuous descent going, the VDEV is going to show you deviation with respect to levelling off and ...

2020年6月30日 · I've recently availed of your product and am currently a type-rated A320 pilot. I'd just like to ask why the "yo-yo" or the magenta donut indicating VDEV as well as the actual VDEV that shows when you arm the approach on the FCU are both showing green instead of the standard magenta?

2014年2月13日 · 空客 显示v/dev是什么意思 . 哦，第一次飞空客发现这个问题，感谢楼上两位

如果GPS PRIMARY,机组应监控VDEV，XTK，飞行计划.此外，对于VOR 或ADF 进近,机组应监控原始数据。 如使用恒定下降角下降,应保持IF高度限制通过IF,在合适的下降点之前0。 3海里拉出FPA旋钮，按照最后进近段给定梯度恒定角度下降。 下降角及下降点计算：tan2.9°≈5.0%≈300ft/1nm tan3°≈5。 2%≈320ft/1nm tan3.2°≈5。 6％≈340ft/1nm＊ 传统的非精密进近采用阶梯下降，在MDA（H）改平，然后过渡到目视进近阶段并着陆。
