Abstract: In order to determine the most critical condition for dynamic impact test of aviation seat, this paper carried out the analysis and calculation of dangerous condition selection for a certain type of aviation seat in two stages of displacement loading and impact loading, based on the study of Article 25.562 of Chinese civil aviation regulations(CCAR), Federal Aviation Administration(FAA) AC 25.562-1B, Society of Automotive Engineers (SAE) AS8049B and other relevant airworthiness regulations and technical standards. The most critical condition for dynamic impact under various predeformation of the floor during the airworthiness test is evaluated and the forensics test of airworthiness is completed according to the conclusion. This method can be applied to the selection of critical conditions before dynamic impact test of various types of aviation seats.

Key words: aviation seat, dynamic impact test, most critical condition, airworthiness
