Modern maintenance intervals also depend on evidence about how engines behave over long periods. The illustrative example specifies three engines running for 250,000 hours each, alongside continuous maintenance and recorded results. Computer calculations and fatigue averages can supplement practical running tests. Test engines may be connected to the electricity grid so their output is useful during endurance work.

Engine endurance tests behind maintenance intervals
Long maintenance intervals require endurance evidence, supported by fatigue calculations and practical tests whose output can supply the electricity grid.
