CVR/FDR uplink wouldn't save lives
- whatever happened would still have happened, and yes you would have known more about why
- it would be expensive, expensive enough to install and run that some operators would not be able to afford it
- pilots would resent being spied and it would cause a lot of money
GPS track logged to satellite every 5 minutes (battery backed, trickle charged) would be simple and cheap
- would it save lives? possibly since SAR would know where to go to look
- possibly a military plane could have escorted a disabled plane to a safe landing ... if they knew where it was and the safe landing was possible.
- Maybe the ground systems could be enhanced to give warning that a plane was 'outside' it's planned corridor - as early warning that something is wrong

Commercial aircraft crashes themselves are very rare when you take into the consideration the amount of them that are in the air at any one time. If one company manufacture 10,000 FDR's, how many in the whole serviceable lifetime are called into service? How many times in the last 30 years have you known a CVR/FDR save lives? As far as I'm concerned if the technology saves just one life in those 30 years it was worth it, which one of us do you think the pax relatives will be in agreement with?
If this aircraft had been equipped with GPS of that kind would it have taken 2 or 3 weeks to reach the ACTUAL search area?
The problem of two weeks is a problem of money and politician's careers. These are nothing to do with airline safety.

DAY 19:
[6:14pm]: Highlights from today's press conference:
- New satellite images have spotted 122 objects - between one and 23 metres in length - in a 400 sq kilometre debris field. Some appear to be bright which could indicate that they were solid material.
- Australia has divided search area into east and west, 12 planes will search both areas
- On Malaysia’s image getting hit by international media, Minister Hishammuddin Hussein said attention would fall on Malaysia as there have been no debris linked to MH370 yet. He said Malaysia has done an ‘admirable job’ coordinating 26 countries during the events of the past 17 days. “I think history will judge us well”.
- On engagement with families in China, Hishammuddin said MAS has done everything to support the next of kin and will continue to engage with them, saying Malaysians and people of other nationalities have lost their loved ones as well.
The Malaysian transport minister says the images, taken on 23 March, showed objects up to 23m (75 ft) in length.
Some of the objects captured by France-based Airbus appeared bright and were possibly of solid material.
A further 122 objects potentially from missing Malaysia Airlines flight MH370 have been identified by a satellite, a Malaysian minister says.

Its not just about saving lives, its the families of the loved ones not knowing where the Aircraft is, also if an Aircraft is found quicker it cuts down on resources looking for it and the chances of losing valuable data and evidence.
In my opinion the location of a Commercial Airliner should always be known even if it has disappeared of the Radar.

Originally posted by anterian View PostIt seems that one objection to an automatic GPS reporting device is that it could still be turned off either intentionally/maliciously or by a total power failure. A trickle charged sealed unit I would think overcomes this objection. My remark was not specific to this flight other that it points out the need for such a device.
What facts?

Originally posted by Exadios View PostI'm still trying to understand which problem automatic position reporting is meant to solve. For instance, how many people on this particular flight that are now dead would be alive id this equipment had been installed? The answer is zero.
In fact I can only think of 2 possible instance in the last 30 years where this sort of equipment might have saved lives. No doubt there are some others but they are extremely rare.
If this aircraft had been equipped with GPS of that kind would it have taken 2 or 3 weeks to reach the ACTUAL search area?

Originally posted by Exadios View PostI remind you that there is no evidence that anything was turned off on this flight. And, if equipment was turned off, there is no evidence that there was any malicious intent. So what issue is your suggestion addressing?
Also keep in mind that there are very few conditions that are more serious than a fire on board an aircraft.

Originally posted by iazoniccc View PostIndeed there is no place in the flight deck for my desktop pc, I suppose what I am trying to say is that what i have outlined earlier provides an additional layer of security to any post-accident investigation, like this one.
If we're calling a spade a spade, these pieces of equipment probably didn't fail simultaneously. While it remains a far-out possibility, there is also no evidence it was damaged by fire.
Indeed electricity can cause a fire, disconnecting its supply will not extinguish an existing fire, it is the source of ignition. As long as the fire has fuel and oxygen, it will continue on its path. If my set top box caught fire I cannot extinguish it simply by pulling the plug.
A computerised circuit breaker system would obviously have the ability to detect a fire and shut down the component, while at the same time preventing the same component from being shut down without good cause.
Also would like to raise an issue with your previous comments about safety and streaming data/GPS. Human beings have been known to survive aircraft crashes before, who's to say there were no human soul's to have survived this impact only to be killed by the ocean? If SAR had known the exact location they could have got straight to the last known coordinates and possibly found survivors.

There is some evidence that the pinger on Air France 447 do not work at all. After the searchers recognized that possibility they feed that into their model and, because of the revised recommendation, found the wreckage a week later.

Originally posted by smay69 View PostAren't the flight recorder pings only supposed to last 30 days. Isn't this past the 30 days?
Anish Patel, president of beacon manufacturer Dukane Seacom Inc. told CNN
"After 30 days, the battery will continue providing power and the beacon will ping, but the output will quickly drop, Patel says.
"As the battery 'wears down' the pinger output decreases until the battery reaches a point that no ping is emitted," Patel wrote in an e-mail to CNN. "The pings get lower and lower in 'volume' as the battery weakens."
"Our predictive models and lab tests show 33-35 days of output before we drop below the minimal value," he wrote. "Depending on the age of the battery, it could continue pinging for a few days longer with progressively lower output levels, until the unit shuts down."
