摘　　要：IMA系统认证过程中,DO-297提出的增量式认可方法将IMA系统认证划分成多项任务,分别获得局方对每个任务的认证信用并积累,最终实现整个IMA系统适航认证的目标。DO-297任务1、任务2的IMA模块认可实现IMA模块级的认证工作,而IMA平台以及驻留功能/应用相关的TSOA也可以为IMA模块级认证工作提供一定的支持。因此,如何复用已获得TSOA的认证信用来支持IMA系统认证、以减少IMA系统适航工作量,成为了IMA系统认证和局方适航审定的关注点。从IMA增量式认可、TSOA以及已获得TSOA的组件在IMA系统的应用这三个方面进行阐述,目的是通过研究掌握IMA系统认证过程的要求,促进IMA系统的适航审定工作。The release of the guidelines DO-297 addresses the challenges of IMA development and certification.In DO-297,IMA incremental acceptance includes 6 tasks, accumulating certification credit in tasks, and finally achieving the IMA system installation approval or credit for certification.IMA module acceptance(i.e.DO-297 task 1,task 2) and TSOA are the basis of IMA certification.How to reuse the certification credit from authorized TSO to support IMA certification in order to reduce the workload of IMA certification has become the focus of IMA certification and airworthiness authorities.This paper describes IMA incremental acceptance, TSOA and the use of authorized TSO components in IMA system.The purpose is to learn more skills on IMA certification process and promote the airworthiness certification of IMA.
