Abstract
As a rule, the lifetime of any system (component) can be measured and observed on more than one time scale. There are two widely used “parallel” time scales for cars: the calendar time scale and the mileage scale. For aircraft frame, three time scales are popular: the calendar time scale, the number of flight hours (time in the air) and the number of takeoffs/landings. For jet engines, the age is measured in operation hours and in operation cycles.

Counting time is not so important as making time count.

You will never “find” time for anything. If you want time, you must make it.
