Abstr: To compare the "frontside" control strategy and "backside" control strategy in carrier landing, a dual-channel pilot model in pursuit tracking flight is established.

文章摘要：为了比较前面与背面这两种飞行员着舰时所采用的操纵策略，建立了双通道飞行员跟踪控制任务模型。

In some instances, this effort is extended to include sending messages through to backend service provider applications to ensure that both frontside and backside links are in service.

有些情况下，还会将消息发送给后台服务提供者应用程序，以确保前台和后台连接都能够正常使用。
