My understanding is that there IS realtime telemetry for engine parameters. Multiple redundant location data, on the otherhand, mustn't be high on priorities as there 'should' be many locations monitoring the planes' progress. Can't be hard to add in a few more bits for GPS co-ordinates..

Technically real-time data transfer can be done easily...apparently the cost is too high...about $300M per average size airline according to some estimates I heard

I actually don't think the statement about safety is true...air travel remains one of the safest way to travel...theer are 40,000 people dying in car accidents in North America alone...and another 30,000 annually in hospitals due to wrong diagnosis or medication

Was watching the news yesterday they said its been 5 days and no information could be found about the missing plane, now Indian Government is also going to help in search. Its really so tough time for the families of people on board the flight. Airtravel is no longer safer these days.

The GPS satellites are transmitters.  A GPS unit, if it is able to receive signals from 3 GPS satellites, calculates the position of the unit from the information contained in the received signals.  So to track an aircraft by GPS, a GPS receiver unit on the aircraft would track the aircraft, and then the position would need to be relayed automatically to a remote site, perhaps by a satellite internet connection.

This is what sticks with me. It seems that we should have all kinds of rea-time data flowing out of these flights, a simple beacon at the very least. We should know EXACTLY where that transmission stopped.

Just a wild thought.  

The flight control centeres are still using the ages old Radar technology for keeping track of the air-borne planes. But when a plane crashes or has to have a forced landing on an unknown surface, this Radar contact is lost and if the other communication systems on board have failed then it becomes a herculian task to locate the illfated plane.

 

Can a satellite tracking based technology ,like GPS,  be employed so that the location of the plane can be pin-pointed whether it is air-borne, laned  or has crashed.

What you suggest is possible, but airlines will not do so for cost reasons. Same suggestion came up during the Air France episode. Remember how long it took to fit collision avoidance systems. Even tne radios seem to use terrestrial relay stations, thought there would be default backup sat. radio I would go one step further, two external low res cameras along with a cockpit camera.

Yes, probably what makes this most frustrating for engineers is how an airplane incident should be readily debugged but isn't. Some cases still open, so prevention is still not in our grasp.
