Description
Factors contributing to the effectiveness of prelaunch testing are examined from a systems viewpoint. The complexity of manned space vehicles increases the quantity of test data that must be evaluated before launch can take place.
The effect of these factors on prelaunch checkout is to place greater emphasis in the care of establishing: (1) accuracy and error budgets, (2) test techniques and equipment design, and (3) methods, plans and procedures for carrying out the prelaunch test program.
By defining checkout effectiveness in terms of probabilities of undetected failures and false alarms at time of launch, the constraints on the above categories can be shown in numerical terms. Interrelationships between test intervals, percentage of system tested, measurement accuracy, stimulus and measurement techniques, and procedures in use of the test system are developed.
