In what situation would the term 'no show' be applicable to a crew member?

The term 'no show' applies specifically to a crew member when they fail to report for an assigned duty. In the context of airline operations, being a 'no show' indicates that a crew member was expected to be present for a flight or duty assignment but did not arrive without prior notice or justification. This situation can significantly affect flight schedules, operational efficiency, and safety, as crew availability is crucial for maintaining the flow of flights and ensuring compliance with regulatory requirements regarding crew duty hours.

Arriving late for a flight, requesting a leave of absence, or canceling a scheduled assignment do not fit the definition of a 'no show,' as these actions involve either some degree of communication or a legitimate reason for absence. In contrast, a 'no show' typically implies a complete absence without any prior communication or indication that the crew member would not be reporting for duty.
