“I’m preparing to test an aircraft engine in the test tunnel. I’m attaching a cable harness now because even engines of the same type may have different connectors, depending on the aircraft model which they are used. It takes four of us about three hours to get a Boeing 747 engine like this one in place. Are the bolts tight? Have the fuel, power and air lines been laid? If so, the test can begin. In two hours, we simulate every stage of a flight, letting the engine run at full and medium throttle, and idle. Calibrated instruments collect data series that are then analyzed. Sometimes, but only rarely, do we need to replace small control units. Finally, we check the oil and fuel filters, eliminate any leaks, and are generally done within 12 hours. In some circumstances, other coworkers will equip the engine with any last components that might still be missing, and then the engine is reinstalled in the aircraft.”
