Scheduled time of departure, often referred to as STD, indicates the specific date and time a flight is set to leave its departure stand. This term is mainly relevant for passengers rather than for operational staff. When you check this information on public displays at airports, it will typically be shown in local time, whether standard or summer, and formatted in a 24-hour clock. If there are any changes to the scheduled time, you’ll find updates either in the Remarks section or in a separate column labeled “Estimated time.”
