A jump seat officially known as an auxiliary crew station, is a seat in an aircraft cockpit for individuals not operating the aircraft. These might include training pilots, off-duty crew in transition to another airport (see deadheading), government officials (such as Federal Aviation Administration staff), or other airline staff.
The term is also used to refer to the crew seats located in the cabin which are occupied by a flight attendant or other cabin crew during takeoff and landing. These cabin jump seats are typically located next to or near emergency exits so flight attendants can quickly open the exit in the event of an evacuation. Also, these seats usually fold up and out of the way when not in use to keep aisles, workspaces, and emergency exit routes clear.
Some aircraft have no jump seats in the cockpit, while others have one or even two. In most airliners, the observers\' seats have an audio selector panel so that the observer can monitor or participate in flight communi
