Additional breakthroughs in display technology are the  new electronic chart systems or electronic flight bags that  facilitate the use of electronic documents in the general  aviation flight deck.  [Figure 1-7] An electronic chart or  flight bag is a self-powered electronic library that stores and  displays en route charts and other essential documents on a  screen. These electronic devices can store the digitized United  States terminal procedures, en route charts, the complete  A/FD, in addition to 14 CFR and the AIM. Full touch-screen  based computers allow pilots to view airport approach and  area charts electronically while flying. With FAA approval, an operator may replace paper charts as well as other paper  materials including minimum equipment lists (MELs),  standard operating procedures (SOPs), standard instrument  departures (SIDs), standard terminal arrival routes (STARs),  checklists, and flight deck manuals. As with paper flight  publications, the electronic database needs to be current  to provide accurate information regarding NAVAIDS,  waypoints, and terminal procedures. Databases are updated  every 28 days and are available from various commercial  vendors. Pilots should be familiar with equipment operation,  capabilities, and limitations prior to use. 1-11
