The FAANASA jointly sponsored Controlled Impact Demonstration CID test was conducted. The CID test was a major milestone in a series of inter- related analyses and test prescribed in the FAA Crash Dynamics program. Prior to the CID test, several section and impact tests including analyses were performed. Subsequent to the CID test, correlation between KRASH pretest analyses and actual test data was evaluated. The actual CID test resulted in an unsymmetrical impact which was modeled and the results compared with the recorded test data. Analyses are performed for air-to-ground, ground-to-ground, and longitudinal-only impacts. The results are presented in the form of triangular pulses with definition of the peak amplitude, base time duration and pulse change of velocity. The analytically obtained data are integrated with the full-scale aircraft and section test data to formulate crash design velocity envelopes. The results of the study are used to suggest seat dynamic test conditions. Keywords Dynamic pulse, Design criteria, Transport category airplanes.
