The application provides an aircraft longitudinal limit overload limit value calculation and alarm method. A flight control system receives fuel oil information sent by an electromechanical system, plug-in information sent by an avionic system and Mach number information sent by an atmospheric system, and a maximum allowable limit overload of the aircraft in the state is calculated in real time. Meanwhile, the current plug-in state, the residual oil quantity and Mach number information are monitored and the effectiveness of the longitudinal limit overload limit value is judged in real time; alongitudinal overload safety limit value can be set under the condition of an input information fault; longitudinal overload of the aircraft in the state is acquired in real time through the flight control system; after derivation and filtering, an alarm judgment function is jointly formed by the longitudinal overload and the real-time longitudinal overload of the aircraft, and an alarm is sent toan aircraft cockpit in real time, so that the purpose of giving an alarm to a pilot in advance when the longitudinal overload is close to a limit value is achieved, and the purpose of ensuring the flight safety of the aircraft is achieved.

    本申请提供的飞机纵向极限过载限制值计算及告警方法通过飞控系统接收机电系统发送过来的燃油信息、航电系统发来的外挂信息、大气系统发来的马赫数信息,实时计算飞机该状态下的最大允许极限过载。同时,通过对当前外挂状态、剩余油量、马赫数信息的监控,实时判断纵向极限过载限制值的有效性,可以在输入信息故障的情况下设置纵向过载安全限制值,并通过飞控系统实时采集飞机该状态下的纵向过载,经过求导与滤波后与飞机的实时纵向过载共同组成告警判断函数,实时的向飞机座舱发出告警,从而在纵向过载有逼近限制值的趋势时,达到向飞行员提前发出告警的目的、确保飞机飞行安全的目的。
