目视飞行

For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.

对于以目视飞行规则飞行的飞机，是飞机将到达机场上空的估计时间。

In the subjects given, learners operate an integrated simulator landing stage of flight data to meet the aircraft and instructors to give students hands-on consolidated results. And then for the visual route trilateral, quadrilateral, and five edge-to-landing phases, with 37 operators' experiments through interviews with senior instructors, the instructors selected seven simulator modules to assess and define the effectiveness of the actual operation of the parameters. Through the way of neural network learning , the establishment of the definition of parameters of simulator training with the students finished the cause and effect comprehensive results relationship, so this research create a set of objective assessment of the effectiveness of flight training simulation platform.

在给定同样操作课目之下，以学员操作落地阶段之模拟机综合飞行数据，配合学员实际操作飞机教官给予之综合成绩，再针对目视航线三边、四边及五边到著陆阶段，以37位操作者为实验，各选取七个模拟机数据，透过资深教官访谈，定义教官评量学员实际操作成效之参数，透过类神经网路的学习，建立模拟机定义参数与学员完训综合成绩的因果关系，如此即可建立一套可以客观评估飞航训练成效的研究模拟平台。

At last, a practical engineering example under VFR is given and a detailed analysis on the model is carried out.

最后给出目视飞行条件下的一个实例并对此模型进行了详细的分析。

Norm: What's VFR?

什么是目视飞行规则？

To provide a direction or suggested heading to VFR aircraft as a method for radar identification or as an advisory aid to navigation.

作为雷达识别或领航咨询协助，为目视飞行的航空器提供方向引导或航向引导。

CONTROLLED AIRSPACE, An airspace of defined dimensions within which air traffic control service is provided to IFR flights and to VFR flights in accordance with the airspace classification.

受管制空域，一个范围明确的空域。在该空域内，仪表飞行规则飞行和目视飞行规则飞行有空中交通管制服务。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
