Multiple and complex problems of providing an adequate restraint system are discussed in these phases: Design, support system details, test criteria, and crash analysis.
Design requires more knowledge of man's critical properties: How and where to provide restraint and support to give man a better chance of surviving crash conditions.
Design detail is of great importance in three major categories:
Test criteria should provide validation of an initial hypothesis and, as additional research information becomes available, the quality and significance of test programs will improve.
Crash analysis offers authoritative evaluation of a restraint system since no other method can simulate the relation between the fuselage structure and the seats and restraint harness.
