The point would be cost savings. You can replace every paper document in the cockpit except navigation pubs. Take a look at how many books that is on a 767. You also get to fire all the people responsible for maintaining those books and you get the weight reduction from taking them off the aircraft.

What Delta however wants is a lot more functionality then the Ipad can provide. They want it to interface with both dispatch, crew scheduling, maintenance and the aircraft. That kind of capability is months if not weeks away. USAIR is installing a product that looks much like a Ipad that Boeing markets that can do much of what I mentioned.

Again the Ipad has not been approved for use below 10,000 feet for any part 121 airlines. Most of the stuff quoted here concern part 91 or 135 operations. The better written articles about Alaska mentioned that shortcoming and that they will still carry paper Nav pubs. Delta may yet buy the Ipad as interim deice because it will reduce weight on the aircraft and let them lay off a large number of employees. If I worked in aircraft publications for Delta I would be very concerned about the future of my job.
