| has gloss | eng: A shakedown is a period of testing or a trial journey undergone by a ship, aircraft or other craft and its crew before being declared operational. Statistically, a proportion of the components will fail after a relatively short period of use, and those that survive this period can be expected to last for a much longer, and more important, predictable life-span. For example if an important bolt has a hidden flaw introduced during manufacture, it will not share the usual reliability characteristics of other bolts of the same type. |
