US Air Force Buys iPads To Replace Flight Bags
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."
But printed charts and manuals don't have an 8-10 hour battery time ...
What about when they have to turn them off when the flight door is closed?
The people who have been sniffing around Apple's supply chain say that the iPad3 will have a 2048x1572 screen, etc ... so why not get the iPad2 cheaper, or get the iPad3 for its better display, etc.?
Let's call it what it is, Anti-Social Media.
Wouldn't a device with e-paper (Kindle, Nook, Sony Reader, etc) be a better replacement for books? Those devices have no glare, have all of the benefits listed, and all have a longer battery life.
That is only the fuel, you forgot the cost of printing those books, distributing them, making sure the latest version is on each aircraft, replacing damaged copies, etc.
TFA specifies once that in truth, they are looking at tablets, not just iPads. Than it's back to Apple this and iPad that. If it indeed is a forgone conclusion, they should have explained why. That's some mighty fine journalism, there. Also, they mention iOS isn't certified yet; don't know if any tablet is.
Lt. Col. Glen Roberts, clarified the report, stating the commend "is looking for a tablet device, not necessarily an iPad"
Seeing that there is custom DoD Android edition and clearances, where iOS has not . http://www.bgr.com/2011/12/28/pentagon-approves-android-device-for-department-of-defense-apple-still-awaits-clearance/ . There is even a DoD SDK.
But one thing about the Air Force there are different commands and they all make different decisions . ASFOC will make one decision, AMC another and the ANG another, and they never cooperate, costing tax payers millions.
These are more for diagrams and maps. e-paper is best for text only.
I remember reading an article a while back by a retired USAF pilot where he wrote about the time spent making sure that all the manuals and other paperwork were up to date and the trouble he could get into if it wasn't when someone inspected the aircraft. So I'm guessing that could save more than $1.2 million dollars of aircrew time.
I have to say, it reminds me of the comment an ex-Signals guy doing his amateur radio licence at the local club made, along the lines of "a map with a bullethole in it is a map that's still mostly accurate, but a laptop with a bullethole in it is really just too big to be a useful paperweight"
They are not cheaper than an ipad. In fact they are much more expensive. However, they are designed for use in flight environments, they have input methods specifically designed for use in flight, they are rigorously tested for interference with other devices and certified for cockpit use by the FAA. They also have larger, easier to read displays that are designed to be used in cockpits where it can be either very dark, or the sun can be shining directly on it. They are also wired into the electronics system, can integrate with the autopilot and other aircraft devices, and are not loose in the cockpit. Finally, another plus is that many and possibly all C-5 and C-17 aircraft in operation already have them.
If you are not allowed to question your government then the government has answered your question.
I think the point is that if there are any power ports available--and I don't know if there are, but if they are--it shouldn't be difficult to make an adaptor that can peel off 5V DC and spit it out of a USB-shaped plug.
The CB App. What's your 20?
In particular, any computer needs to be built in the west, with chips from the west, to be trusted.
I prefer the "u" in honour as it seems to be missing these days.
exactly. The west is destroying itself by trusting goods coming from China. Instead, the west's military should require that all electronic be secured by west manufacturing.

So, go ahead and find me a USB port on the flight deck of a C-17. I'll wait <crickets> I thought so. ...
Did you forget that *you* wrote that 28 Vdc was available.
... Whatever they're doing to keep their pads charged beyond normal battery endurance, it'll be a workaround hack (issuing external USB-connected battery packs along with the pad) or some significant auxiliary systems re-engineering of in-service military transport aircraft.
Or it will be a simple DC/DC converter, simpler than the AC/DC converter that every iPad already ships with.
Adapters for 28V dc aircraft environments already exist: http://www.lonestaraviation.com/Power-Adapter-USB-Socket.html
Really? Slashdot is going to argue over whether the military can figure out how to charge an iPad on a C-17? Really?

Which means that the iPad is replacing the paper copies as a backup system to start with. So, if the main system breaks, the iPad needs to work only long enough to find a reasonable field to land at, and not necessarily provide a full-flight's worth of operation. Considering that both pilots will have one, there will be two backups.
I had a hard time believing they'd go for an iPad over a more rugged device, but the article says Special Operations Command already did so. iPads are consumer hardware. From Apple's specs:
* Operating temperature: 32 to 95 F (0 to 35 C)
* Nonoperating temperature: -4 to 113 F (-20 to 45 C)
* Relative humidity: 5% to 95% noncondensing
* Maximum operating altitude: 10,000 feet (3000 m)
Even for a cargo plane, that seems pretty limited. I know they have at least some climate control in flight, but don't they park the planes in arctic and desert environments too? Don't they need the checklists before they start the plane up? Or do they keep them running all the time and only shut down at their home base?

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.
And now if you'll circle back to the start of the discussion you'll see that a converter does have to be specially made because you aren't going to find a standard household powerpoint on a military aircraft.
And you'd be wrong. The C-17 has several "standard household powerpoints" conveniently located at the feet of the passengers seated in the "jump-seats". I'm sure there are even more on the flight deck.
