不好意思楼主,虽然我主飞320,但是波音我多少还是了解一点。
为了图方便,我就截取PMDG Tutorial的话,如果你觉得PMDG的教程有问题或者有的没的,请和他们联系。
you always add at least 5 knots extra to your VREF. In a no wind situation like this, 5 knots is fine, but there are situations involving crosswinds, windshear risk and so on with manual throttle control where you’d add more than 5 to it. Boeing states however that 5 knots is always sufficient when using the autothrottle.
如果我没记错,final appr spd是 Vref+5或风速分量/2。至于侧风和阵风还有不同的算法,下面的表格可以做个参考。
还是希望楼主能虚心学习一下。 |
