As an important part of airworthiness conformity verification, the environment appraisal requirements of airborne equipment (including environmental adaptability, power supply adaptability, electro-magnetic compatibility, fire flammability, etc.) have been attracted the airworthiness authorities, host units, equipment design manufacturers. Due to contradictions between these requirements, how to balance and solve them is the focus of environment appraisal of airborne equipment.
