The invention relates to a system for assisting the pilot of an aircraft, which comprises aboard the aircraft:a computer,a set of sensors able to provide data to the computer and,a seat for the pilot equipped with haptic actuators controlled by the computer. The metallic peripheral belt includes at least one elastically deformable portion that prevents the bulk glass-metal seal from getting damaged and is no more vacuum tight when subject to the evacuation process of the envelope and the thermal treatments of the panel and the potential reciprocal displacements of the glass plate and the joined metallic peripheral belt. Once on the LAN, the device can exchange information with a store computer such as by sending the list of voice inputs to the computer and receiving back information about the location of those items in the store. The power management unit, the WIFI module and HDMI are coupled to the central processing unit respectively and the central processing unit decodes the sharing information for transmitting the decoded information to the display terminal by way of HDMI. The focusing unit corrects the focusing status of the focus lens detected in the other focus detection area based on the focus correction information stored in the memory and achieves focusing.
