Autonomous systems increase the robustness and safety of current aircraft and to support simplified vehicle, reduced crew, and single pilot operations. The autonomous systems aid air crews in their handling of non-normal, high workload, aircraft upset scenarios. The upset scenarios include the recovery from attitudes outside of the normal operating envelope that even the most robust automatic flight control systems currently in service today do not support.

Multi-axis upset recovery system

A system for an airborne platform includes a sensing device, an automatic throttling system, and a processing circuit. The sensing device is configured to measure a current airspeed of an aircraft. The processing circuit is configured to receive a control input comprising a current airspeed value, an airspeed reference value, a maximum adder threshold, and a minimum adder threshold. The processing circuit is further configured to calculate an airspeed error value based on the control input. The processing circuit is further configured to determine a programmed error value based on the calculated airspeed error value. The processing circuit is further configured to calculate an adder value by applying an integration function to the determined programmed error value and to determine a dynamic airspeed reference value based on the calculated adder value. The processing circuit is further configured to transmit the dynamic airspeed reference value to the automatic throttling system.
