Things that get integrated into the cockpit tend to be hard to change and have long legacy lifetimes. If you ever want to gouge your eyes out for an evening, peruse the spec for CADRG, which is the file format used by military cockpit in flight displays: http://earth-info.nga.mil/publications/specs/printed/89038/89038_CADRG.pdf http://earth-info.nga.mil/publications/specs/printed/89038/8... It's a format designed for ultra-fast decoding, but it's not widely supported and a real mess under the hood. There's some advantage to having things in the pilots hands if the technology is improving rapidly.
