MH370 Search area to be expanded
 
'Should the aircraft not be found within the current search area, ministers agreed to extend the search by an additional 60,000 square kilometres to bring the search area to 120,000 square kilometres and thereby cover the entire highest probability area identified by experthttp://images.intellitxt.com/ast/adTypes/lb_icon1.png analysis," they said in a joint statement."Ministers recognise the additional search area may take up to a year to complete given the adverse weather conditions in the upcoming winter months." '

Cool, more ocean floor data.:p

but
 
the Indian Ocean covers 73,440,000 square km :sad:

and
 
Has there been any cost-benefit analysis been done to justify the cost of continuing to search for the aircraft? :confused:

MH370 contrails have been identified
 
I know the MH370 thread was closed because there were no real news but I think this is really breaking.

Can you put a value on finding out the problem/cause that cost an aircraft and lives? If you can do that then a CBA should be easy

neville_nobody 17th Apr 2015 00:10

Given the amount of satellite data that various countries collect these days I find it ridiculous that we are spending tax payers money for ocean floor survey for a foreign registered airliner. Given that the ATSB would not cough up to go and get Pel Air's Black Boxes why are we now mapping the Indian Ocean?

I bet MI 6 or the CIA would have some indication of what went on why dont our people talk to their people and cut down this wild Goose chase.

Unless of course this is part of the strategy for whatever reason.

Oh dear. Seriously?
If I squint hard enough I can see...

...anything.


Forgive my cynicism.

Surely, if he wanted to avoid detection, he would have turned off the Chemtrails?
A professional pilot would know that the CIA has sat tracking on the Chemtrails units.

You need to look at the ALARP and SFAIRP if you want to try to answer that.

ALARP - as low as reasonably practicable.

SFAIRP - so far as is reasonably practicable.

The two terms mean pretty much the same thing, and they rely on the concept of “reasonably practicable”, which involves weighing risk against the trouble, time and money needed to control it.

Source: Risk management: ALARP at a glance

The comment that I made was more to the point of “What are the potential safety benefits likely to be gained at this point by continuing the search?”

In other words, is the trouble, time and money being expended on the search likely to provide any significant safety benefit?

It’s not as though there’s all of a sudden a mysterious safety phenomenon that’s started to cause lots of airliners to divert off course for no apparent reason and to disappear without a trace.

So the balance of risk and societal benefit in continuing the investigation of this (so far) one-off event needs to be considered, particularly when you look at the ATSB’s published information regarding the decision ‘…whether to investigate’, and especially in the context of whether there’s any safety value to be gained from continuation of the search in anticipation that it will provide safety actions other than those that have already been suggested.


Level of response
The level of investigation response is determined by resource availability and such factors as detailed below. These factors are presented in no particular order and may, depending on the circumstances, vary in the degree to which they influence the ATSB's decision to investigate and the level of response.
• anticipated safety value of an investigation, including the likelihood of furthering the understanding of the scope and impact of any safety system failures
• likelihood of safety action arising from the investigation, particularly of national or global significance
• existence and extent of fatalities/serious injuries and/or structural damage to transport vehicles/other infrastructure
• obligations or recommendations under international conventions and/or codes
• nature and extent of public, interest, in particular the potential impact on public confidence in the safety of the transport system
• existence of supporting evidence or requirements to conduct a special investigation based on trends
• relevance to an identified and targeted safety program
• the extent of resources available and projected to be available in the event of conflicting priorities
• the risks associated with not investigating including consideration of whether, in the absence of an ATSB investigation, a credible safety investigation by another party is likely
• timeliness of notification
• training benefit for ATSB investigators.

Good question, nicely put, f***ed if I know :8

any pilot worth their salt knows the mintra level.

fastjet45 17th Apr 2015 14:08

It seems to me that they are making a picture fit what they believe are contrails to where they think the aircraft tracked, not actually identifying a contrail found in the middle of a cloud system then confirming it belongs to MH370.

Evanelpus 17th Apr 2015 14:10

That shows me sweet FA, I'm afraid.

Australopithecus 17th Apr 2015 14:48

Nike...I always calculate the mintra level or risk being jumped by those pesky 109s out of Abbeville. Can't be too careful...loose lips sink ships, etc.

We legally have to because the believed crash site is within our SAR region.

If my chopper crashed when we're off of Hawaii then I'd be hoping the local SAR agency would come and look for me rather than not bother since I'm a foreigner. Same deal here.

Australopithecus 18th Apr 2015 08:16

No we don't. We have an obligation for search and rescue only. This is a criminal investigation of events that did not occur in or over Australian soverign territory.

There are plenty of fishing vessels that are lost in the SAR area that get only a short search. One in fact called a mayday with over thirty crew around the same time as MH370. We sent one search flight only.

Except that when you crash your chopper the ELT goes off so everyone has a good idea where you are.

In this instance a multi million dollar aircraft crashes with multiple ELT's and NONE of them work, so we start doing grid patterns all over the ocean?

Contrail analysis via satellite.
 
Kirill Prostyakov and Dr Bobby Ulich have put a lot of effort in this analysis. The derision seen here sounds like the first critiques of the handshake timings by Inmarsat. Little wonder that moderators have chosen to stifle the snarkiness on MH370 threads. " Reddit/r/MH370.com " gives more technical detail.
