calendar time in service (The term "time in service" is clearly defined (CAO part 100.5.0; AAC article 198-2 refers) and is reasonably well understood. To reiterate, aircraft time in service is the "time from the moment the aircraft leaves the ground on a flight until it touches the ground just prior to the end of that flight". It is normally measured in hours. Total time in service is the cumulative time so recorded. "Calendar time in service" is intended to mean the total elapsed time since the aircraft, or component, first entered service. For an aircraft, this would normally mean time since manufacture; for a component it normally means time since the component was first installed on an aircraft. It does not include prior storage time. This calendar time then runs continuously, without interruption for, for example, periods when the aircraft (or component) is temporarily removed from service.
