1. A support system for monitoring an air outlet valve in an aircraft, the system comprising:
- an air outlet valve disposed between an aircraft cabin and the outside atmosphere, wherein the air outlet valve can be fully opened to equalize the air pressure within the aircraft cabin with the outside atmosphere before aircraft cabin doors are opened;
a camera arranged to capture an image viewed through the air outlet valve; and

Abstract
The invention proposes that a camera (18) takes a technical picture of an air outlet valve (10) of an aircraft, and the picture taken of the outlet valve (10) is displayed on a picture display unit (20), for example in the cockpit of the aircraft. By shining light onto the outlet valve from a light source (22), a clear picture with a high level of contrast is produced. The valve setting of the outlet valve (10) can thus be monitored visually, in a reliable manner, by the pilot.
