Boeing successfully completed a high-pressure test, known as “high blow,” on the 787 Dreamliner static test airframe at its Everett factory on Saturday. The test is one of three static tests that must be cleared prior to first flight. During the test, the airframe reached an internal pressure of 150 percent of the maximum levels expected to be seen in service - 14.9 lbs. per square inch (1.05 kilograms per centimeter) gauge (psig). It took nearly two hours to complete the test, as pressure was slowly increased to ensure the integrity of the airplane.
