Method and system for processing airspeed data of aircraft and aircraft

A method for processing aircraft airspeed data is presented, comprising receiving atmospheric data pressure source data; performing first filtering on the atmospheric data and the pressure source data; calculating the airspeed based on the data subjected to the first filtering; performing second filtering on the airspeed; and selecting the airspeed to output using a filtering error-based segmented restriction strategy. The invention further discloses an aircraft airspeed data processing system and an aircraft. According to the scheme, the airspeed display accuracy and stability can be improved. 提出了一种用于处理飞行器空速数据的方法，包括接收大气数据压力源数据；对大气数据压力源数据进行第一滤波；基于经第一滤波的数据，计算得到空速；对空速进行第二滤波；以及使用基于滤波误差的分段限制策略来选择要输出的空速。还公开了飞行器空速数据处理系统及飞行器。本方案能够提高空速显示准确性和稳定性。
