A monitoring system for an aircraft has sensors configured to sense objects around the aircraft and provide data indicative of the sensed objects. A sense and avoid system is designed in a plurality of software layers, each layer functioning in an independent manner. An evasion software layer is made up of fixed, non-modifiable code that meets an applicable regulatory standard. The remainder of the software layers may be made up of modifiable or non-modifiable code configured so as not to adversely impact the functioning of an evasion software layer, even when modified. Each of the software layers of the sense and avoid system may use information from the sensors and information about the aircraft to generate a recommendation which is ultimately used to determine a possible route that the aircraft can follow to avoid colliding with the sensed object. The aircraft may then be controlled, in accordance with the recommendation, to avoid collision with the object.
一种用于飞行器的监测系统具有被配置为感测飞行器周围的物体并提供指示感测到的物体的数据的传感器。感测和避让系统被设计在多个软件层中,每个层以独立的方式运行。回避软件层由满足适用的监管标准的固定、不可修改的代码组成。软件层的其余部分可以由可修改或不可修改的代码组成,该代码被配置为即使在修改时也不会对回避软件层的功能产生不利影响。感测和避让系统的每个软件层可以使用来自传感器的信息和关于飞行器的信息来生成建议,该建议最终用于确定飞行器可以遵循以避免与感测到的物体相撞的可能路线。然后可以根据建议控制飞行器以避免与物体碰撞。
