波音737NG太平洋调机RNAV运行可行性初探

Preliminary Research on Boeing 737 NG Pacific Conditioners RNAV Operation

波音737的早期机型由于受到航程等性能参数的制约,按照西雅图—夏威夷—马绍尔群岛—塞班岛的航路运行。波音737NG对飞机的性能进行了改进,增大了飞机的航程。调机飞行时,波音737NG无业载情况下可达到最大航程,为夏威夷—塞班岛的直飞RNAV运行提供了可能性。通过RNAV运行的前提条件和机载导航设备性能分析,在大圆航线模型下对夏威夷—塞班岛直飞航线进行了航路规划,并以B737—800机型为实例,对耗油量等进行了定量计算。夏威夷—塞班岛直飞航线比传统夏威夷—马绍尔群岛—塞班岛航线缩短688 km,在50 km/h强顶风状态下飞行,航行用油小于15 t,说明在机组经过相关培训并配备专职领航员的条件下,波音737NG太平洋调机具有夏威夷—塞班岛直飞的可行性,减少一次起降并缩短约0.8 h飞行时间。

Due to early voyage of the property parameters,such as restraint,Boeing 737 aircraft was operated according to Seattle-Hawaii-Marshall islands-Saipan island route.The performance of B737—NG was improved to increase the aircraft flight distance.Without pay load,the MAX Range could be achieved to make Hawaii-Saipan non-stop RNAV operation possibly.Through analysis the premise condition and airborne navigation equipment performance of the RNAV operation..In the great circle route model,planning on the Hawaiian-Saipan direct route,with B737—800 for example,quantitative calculation the fuel consumption.Hawaii-Saipan direct route than traditional Hawaiian-Marshall islands-Saipan routes shorten 688 kilometers.In the strong dead wind condition,the wind speed is 50 kn/h,oil sailing less than 15 tons.After related training of flight crew and equipped with full-time navigator,the civil aviation Boeing 737—NG has the feasibility of non-stop flight,reduce a take-off and landing and the time will shorter 0.8 hour.
