哎，真不知道怎么一个两个都把它藏着掖着，查了半天资料以及IDA逆了来电精灵和一个一键飞行工具才明白了其中的内幕。

成品界面看附件图。

不多说了，用法是：
SetPhoneState(LINEEQUIPSTATE_MINIMUM); //开飞机
SetPhoneState(LINEEQUIPSTATE_FULL);   //安全着陆

TAPI标准里应该是先用lineUnregister注销网络然后再lineSetEquipmentState关闭GSM，但是注销网络这一步会导致程序停止响应一会儿（因为lineUnregister要等待返回，除非用多线程去做），同时由于要注销网络，会稍慢一些，而国内其他飞行功能软件都是跳过这一步直接关GSM的，大概现在的GSM通讯升级了吧，关闭前系统会自动通知基站电话关闭的，所以去掉了lineUnregister这步，达到迅速关闭GSM的目的。
