It gives the final 10 positions recorded by FR24. Last position wasn't exactly at IGARI: it was 2.75 nm beyond that on a steady course of 040. Like it's aiming at BIBAN rather than BITOD.
BIBAN (042), or ANHOA (038), and such shortcuts isn't unusual... and yes, some might take the shortcut without ATC clearance if it doesn't deviate by "a lot"...
Now... did it go 040 because they went for a shortcut? (habit)...
Or something failed? (Pihero's theory)
Or someone just slapped on the HDG SEL? (which is open to Pihero's theory, or a 'deliberate action', but discounts '

I'm sure I'm repeating myself from 2,000 posts ago, but Google Maps for example caches a ton of data locally. If I switch my phone to airplane mode and access Google Maps
If you've preloaded the tiles on route and is still within the cache... yes. If you haven't... no luck.

Older BlackBerrys had an option to turn off AGPS, so it wouldn't look for cellular/WiFi "assistance" to get a lock, it will try only with satellite signal, location may not be perfect but will be in general area.
On the androids I used onboard, I switched off the AGPS. I used another GPS
software to see what the phone's GPS
was seeing. It was not able to pick up the different satellites in different directions, it just came as the satellites in 1 direction on the horizon.. the GPS
then couldn't get a fix.

ICAO should mandate (I guess they can only request) airlines to pass-on location information thru aircraft's WiFi Router (like all WiFi Routers do on earth). One can develop an app to capture your location and store in cloud using "passenger paid WiFi service". No cost to airlines.
This is a kneejerk reaction.
The "No cost to airlines" is a fiction.
Who's going to pay for the system? The WiFi Routers, the STCs if required? etc etc etc...
Part of what I do outside my job is toI sell solutions like these... no cost to airlines is a fiction. Some airlines are also too damn stingy...
|Quoting boacvc10 (Reply 274):|
Sorry, the aircraft's WiFi access point is actually not directly on the internet as you know it, and is transported on a proprietary network to a vendor's network operations center, where the data is uncompressed, filtered, routed, switched to its destination networks. You won't be able to reach the Wi-Fi access point on the aircraft from outside of the network as there will be multiple private gateways and firewalls separating the airborne network with the public network.
, question: How are you going to connect it to the vendor network operations center? Secondly, who's going to pay for it?
|Quoting bond007 (Reply 289):|
If passengers had smartphones with Google Maps (very likely), and if they were able to get satellite reception ...they most likely would have been able to determine their position with some degree of accuracy had they any reason to try to.
, don't pre-load the data for the routes and destination onto the cache. Get onto the airplane, and try to get your GPS
running on your phone...
I want to know what the various results are based on what they've tried... not based on "it should this and that".
I've tried it and wrote what I got.

No cost to Airline, pax using the bandwidth they paid for.
Gogo ATG network is unique, but again, the infrastructure that Gogo invested in on the ground isn't exactly small.
For non continental landmass of a single country, the Gogo ATG solution is not practical. So you'd need satcom.
1. Who's going to buy the satcom?
2. Who's going to pay for the airtime?
3. Who's going to buy the other equipment (onboard routers, etc)
Once you go from ATG to SatCom, the cost structure changes... and the "no cost to the airline" is a fiction.
|Quoting sipadan (Reply 314):|
However, when further pressed on Inmarsat alone releasing the raw, implied that they were legally restrained from doing so, as it was only the Malay investigation that 'legally' could release it.
The raw data of the satellite data packets (non-billable packets) won't be released under national security clauses and various non-confidentiality clauses between Inmarsat and various "chief client" government customers.
|Quoting aftgaffe (Reply 318):|
One explanation that might potentially make sense, assuming the raw data has at most only been released to the AAIB, is that UK national security laws (or potentially trade secrets laws, but I'd be more dubious of that) prevent further dissemination period. But I don't know what the national security concern would be and of course that does not square with what Inmarsat said above (for whatever that's worth).
The national security interest concerns (not national security concern) is there, and it prevents the whole raw data to be released. So Inmarsat has to be careful on how to release the info and the wording of the release.
And then, they decided to offer these "location through the non-billable data packet" that is previously confidential, as free tracking to the industry with no change to the existing set ups... If that's the case, Inmarsat, please, release the coordinates...
I better stop now before I get "visitors"...
