US Air Force Buys iPads To Replace Flight Bags 348
redletterdave writes "Following the precedent set by commercial airliners, the U.S. Air Force plans to buy up to 18,000 iPads for its Air Mobility Command (AMC), replacing heavy flight bags with light and efficient Apple iPad 2s for the crews that fly cargo aircraft. The devices will reportedly be used by the crews on the C-5 Galaxy and C-17 Globemaster aircraft. There are several benefits to using electronic flight bags instead of physical versions. For one, the iPad can instantly update charts electronically, while the AMC would require flying charts get reprinted every 28 days to stay up-to-date. By cutting publication printing and distribution costs, and exchanging 70 pounds of paper for a 1.3-pound iPad, the Air Force can save some serious cash, including more than $1.2 million worth of fuel per year."

Always. In it's most simple case the AC needs to be converted to DC before being converted again to DC.
In the most common case the DC is smoothed by capacitors that need to withstand 400V and a high ripple.
In the most ideal case (anything larger than that cheap $5 chinese crap you normally get with a phone) you need to isolate the output from the input via a small transformer, and often feedback through optical isolation.
In every case DC-DC converters are simpler than AC-DC converters.

Re:Battery (Score:5, Informative)
If you want to do it in the most horribly inefficient fashion, yeah, that will work.
Shunt regulators really suck for anything other than minuscule amounts of current, for a reference as example.
A shunt reg has to burn more than just the voltage drop (the extra in the zener, to keep the voltage level). It has to be sized to draw slightly more than the device's maximum draw at all times.
So - say full load on the ipad is 2A, idle is 1A. We design this to draw say 2.2A, a little room so it doesn't drop out on peak - so we're burning 28V * 2.2A = 62W all the time, while the ipad is getting 5W average, or 10W peak (out of the 62W).
8% efficiency at idle. 16% at full load.
A better setup is a normal linear reg (which can be made up of discrete parts, or integrated like the venerable 7805), which will basically only burn the drop (there is a small amount for ref, but basically negligible)
So 23V drop * 1A draw = 23W burnt. total consumption 28W.
~18% efficiency at idle or full load (this one is linear..)
Typically you wouldn't do this though, you'd use a transformer off the AC supply (assuming their is one) to get the voltage into the ballpark, then rectify and reg, to get efficiency up over 50%, maybe as much as 80% with decent design and low dropout reg. (transformers are heavy and bulky though - which is why planes use 400Hz).
SMPS is of course, the best, some modes exceeding 90% efficiency - but that didn't always exist. A lot of old military transceivers used dynamotors, which is the most efficient non-transistorized way to do DC-DC conversion. kinda... funny in a way, so very primitive, but also sort of genius. brute-brilliance, i guess... Heavy, loud, and high maintenance, though.
