Malaysian Airline didn’t buy cheap upgrade that ‘could have found lost jet’
Apparently the Malaysian Airline did not purchase a service package that costs about $10 per flight that would have provided data on MH370's location even if the transponder is shut down. Reportedly the system's use is mandatory on planes flying in the North Atlantic corridor between the Europe and the US but not on other plane routes. Does anyone know if ATC can monitor whether or not the system is activated on international inbound US flights approaching from Asia, South America or… (nypost.com) Más...Sort type: [Top] [Newest]
This FANS info page is from 1997 or earlier. Sounds like Boeing's incarnation of plane-side of NextGen technology. But the page does explain much of the technology clearly.
Much of the novelty at the time was from using satellites to accurately triangulate a precise location for each plane/ handheld device.
But for data transmission, ADS-B can be 'sent by satellite or radio waves'. While radio waves will work in the same areas roughly where radar can be captured (ie. over land or just off shore). Far out in the middle of the world's oceans and/or polar regions, some kind of long range communications like satellite comm would be necessary for anyone not on the plane to know where the plane is located.

Was FANS available for the 777 in 2002 when the missing aircraft rolled off the line?
Unless a 777 and similar class aircraft have this capability fully functional they should not be allowed into US controlled airspace.
I remember well when Lufthansa ripped out all the standard issue avionics hardware and software in the Boeings. They found a link where Seattle could intervene into the FMS and take over the flight. Replaced it all with home grown Siemens and Lufthansa specific software. They never flickered at how much this cost..
...through a satellite data link, airplanes equipped with FANS can transmit automatic dependent surveillance reports with actual position and intent information at least every five minutes. The position is based on the highly accurate Global Positioning System (GPS).
....777 includes FANS 1 as a basic feature, as of press time,
