A system for managing multiple independent cockpit displays, comprising: a first display device and a second display device in a cockpit of an vehicle, wherein the first display device and the second display device are configured to receive input from a user and display pages to the user, wherein the pages are pre-defined by a plurality of parameters in a page definition database; a display device control system comprising a processor coupled to a memory, wherein the memory stores the page definition database, wherein the processor is configured to: receive a request from a user to display a first page on the first display device; retrieve a flag associated with the first page, wherein the flag is a predefined parameter in the page definition database, wherein the flag indicates whether a particular page is safe or unsafe for simultaneous display and editing on two or more display devices; when the flag associated with the first page indicates that the first page is unsafe for simultaneous display and editing or the two or more display devices, retrieve (222, 224) a group designator associated with the first page and a group designator associated with a second page displayed on a second display device, wherein the group designator is a pre-defined parameter in the page definition database, wherein the group designator identifies pages that are related to one another; and control display and editing of pages on the first display device in response to the request based on: the flag associated with the first page; or the flag associated with the first page, the group designator associated with the first page, and the group designator associated with the second page; wherein the processor is configured to display (206, 230) the first page on the first display device with editing enabled when: the flag associated with the first page indicates that the first page is safe for simultaneous display and editing or the two or more display devices; or the group designator associated with the first page and the group designator associated with the second page are different; and wherein the processor is configured to prohibit selection of the first page when the group designator associated with the first page and the group designator associated with the second page are the same. a first display device and a second display device in a cockpit of an vehicle, wherein the first display device and the second display device are configured to receive input from a user and display pages to the user, wherein the pages are pre-defined by a plurality of parameters in a page definition database; a display device control system comprising a processor coupled to a memory, wherein the memory stores the page definition database, wherein the processor is configured to: receive a request from a user to display a first page on the first display device; retrieve a flag associated with the first page, wherein the flag is a predefined parameter in the page definition database, wherein the flag indicates whether a particular page is safe or unsafe for simultaneous display and editing on two or more display devices; when the flag associated with the first page indicates that the first page is unsafe receive a request from a user to display a first page on the first display device; retrieve a flag associated with the first page, wherein the flag is a predefined parameter in the page definition database, wherein the flag indicates whether a particular page is safe or unsafe for simultaneous display and editing on two or more display devices; when the flag associated with the first page indicates that the first page is unsafe for simultaneous display and editing or the two or more display devices, retrieve (222, 224) a group designator associated with the first page and a group designator associated with a second page displayed on a second display device, wherein the group designator is a pre-defined parameter in the page definition database, wherein the group designator identifies pages that are related to one another; and control display and editing of pages on the first display device in response to the request based on: the flag associated with the first page; or the flag associated with the first page, the group designator associated with the first page, and the group designator associated with the second page; control display and editing of pages on the first display device in response to the request based on: the flag associated with the first page; or the flag associated with the first page, the group designator associated with the flag associated with the first page; or the flag associated with the first page, the group designator associated with the first page, and the group designator associated with the second page; wherein the processor is configured to display (206, 230) the first page on the first display device with editing enabled when: the flag associated with the first page indicates that the first page is safe for simultaneous display and editing or the two or more display devices; or the group designator associated with the first page and the group designator associated with the second page are different; and the flag associated with the first page indicates that the first page is safe for simultaneous display and editing or the two or more display devices; or the group designator associated with the first page and the group designator associated with the second page are different; and
