The manuals and charts being replaced are what you normally see pilots carrying around in their satchel. Replacing them with the Apple iPad would amount to such a large difference in weight that American Airlines will save $1.2 million a year in jet fuel costs. American is the only airline that has approval to make the switch and the iPad is the only tablet allowed to be used inside the cockpit during a flight.
American Airlines and UAL were to test out the program to replace the bulky manuals with the sleek tablet. The test was later expanded on American to cover all aspects of a commercial flight. The iPads are loaded with a special app approved by the FAA called the iPad electronic flight bag which replaces all of the flight charts and manuals usually used by pilots for navigation and other important functions.
The program will start on American Airlines' fleet of 777 aircraft and will roll out to the rest of the airline's fleet by the end of the year. By next year, American Airlines hopes to have stopped the paper revisions of navigational charts and flight manuals.
