Related to insurances:
The airline’s insurers – Allianz Global Corporate & Specialty and Lloyd’s of London unit Atrium – have already paid more than $300 million for claims related to the crash. Both companies have issued statements saying the discovery of part of the wreckage has not changed the situation, nor their willingness to pay valid claims
[…]
Currently, tenants of the international Montreal Convention limit liability payments from airlines at $175,000 per passenger regardless of whether the airline is at fault.
300M$ divided per 239 death leads to 1,255M$ paid per person onboard
Hunt for Flight 370 to continue at least until June 2016
Consistent with the undertaking given by the Governments of Australia, Malaysia and the People’s Republic of China earlier this year, 120,000 square kilometres will be thoroughly searched. It is anticipated this will be completed around June 2016.
More than 80,000 square kilometres of the seafloor have been searched so far.
Here is the new area being searched (notice the increased surface area)/alrdy posted:
3 differents ships are now on station :
Fugro Discovery continues to conduct search operations with deep tow equipment and is scheduled to depart the search area around 6 January 2016.
Fugro Equator arrived in Fremantle for a scheduled resupply visit on 21 December. This extended visit will include scheduled engine maintenance operations, and the vessel is expected to depart for the search area around 29 December.
Havila Harmony is conducting search operations using the Autonomous Underwater Vehicle (AUV). The AUV is currently surveying some of the most difficult portions of the search area that cannot be searched effectively using the deep tow sonar.

EU Increases Black Box Tracking Requirements
The regulations will go into effect by mid-2018, and by the end of that year, airlines will be required to track their aircraft over oceans, a provision added in response to Malaysia Airlines Flight 370. […]
Under the rules, the underwater locators in planes’ black boxes will have to work for 90 days instead of the current 30 days, Bloomberg reported Wednesday.

A powerful statement! (Sadly)

Here is a more appropriate article published today in the VillagesSunTime
This last sentence is probably the most sensible wording of the events so far:
The crew’s improper control inputs led to a loss of control which this crew were not capable of recovering from.

*the RTLU is the faulty circuit board governing the travel limit of the rudder trim
Everything is driven by profit, not only aviation!
However, I have just done Boeing 737-800 training at British Airway/Comair training facility in Johannesburg and I can say that they place a HIGH emphasis on safety and CRM to the extent that the airline will commend a pilot for any safety action he/she takes regardless of the cost. For instance a go-around or diversion in poor weather.
Obviously the above Press release is controversial. You are right to emphases that many are standing as real professional and safety is what drive them. Be ensured that it’s not my intention to put the discredit on all (and hence none).
WHat this press release show is that something (at least) is happening and gains a certain momentum. We see some moving forward calling cards for the next round.
QZ8501 as a stepping stone?
Engineers warn of repeat of AirAsia crash
In a statement, Aircraft Engineers International [which represents 40,000 aircraft engineers in 30 countries], said: “The public must be made aware that aviation today is driven by cost. Cost, not safety, is paramount.
“Pilots and Engineers are often placed under increasing pressure to accept second best, in order to ensure aircraft meet unrealistic flight schedules.
[…]
With training of pilots and engineers often the bare minimum, spares and manpower levels reduced to unacceptable levels, although workloads increase, the working life of these safety professionals has become centred on lowering costs.

I am fed-up. Here is what we had to read today:
t was a mismanaged technical problem by the crew that caused the AirAsia Airbus A320 crash, almost a year ago (28 December 2014), in the Java Sea.
According to Indonesia’s National Transportation Safety Committee’s final report, it was a a tiny soldered electrical connection in the top of the vertical stabilizer, or tail, that caused the triggering of an alarm, which in turn indicated a failure of the rudder movement control system.
The captain then actuated the on/off button to reset the system (Rudder Travel Limiter Units). The alarm stopped, but was set off again shortly after. Three times the pilot performed the same operation, but when the alarm sounded a fourth time, the captain tried something else. He attempted to reset the Flight Augmentation Computer that controls the aircraft, by removing and re-inserting its circuit breaker, however, in so doing, the captain inadvertently disengaged the autopilot, and the automatic stall protection.
At 38,000 feet, the aircraft stalled. For four minutes, inappropriate and contradictory actions (miscommunication) of both pilots, led to the non-recovery of the plane, and the AirAsia A320 crashing at sea.
The report points to shortcomings in the aircraft’s maintenance and lack of crew stall recovery training. The accident claimed the lives of the 162 people on board the A320.
The chain of events clearly show that at each step, a comprehensive analysis of the inherent fault of the design done long ago would have led to a different outcome.
Let’s review it briefly (all sourced from the very easily and understandable KNKT report linked above):
– The design of the rudder trim induces some divergence in case of a problem instead of being auto-centered in safe mode just like with a basic set of springs and pulley.
– You need both computer to center it correctly ( this is why they experienced 1.4deg rudder offset (see the BEA comment at the end of the report).
– While the crew did pull physically the circuit breakers correctly, you still need to reset the overhead connected display indicator manually by pulling them off then pushed back on ( yes, just our cheap Window OS devoid of any logics).
– That very low amount of deviation resulted in a 60deg bank in a very short period of time thanks to the inadequate aerodynamic configuration that is not stable in roll (there was no action from the second Pilot during that time).
– The actual “stick” time of that young pilot was so inadequate for him to be in charge of so many life that he over rolled twice attempting to correct with a 60 deg correction on the right and then on the left (~15deg) (Imagine the situation of panic in the cabin after that – poor souls, it is so horrible to think at it). Last time I checked any F16 pilot with half the flight hours and four time the roll rate can manage better (while having no passengers).
– Once it was clear that his second was not able to handle the situation, the Captain tried to maneuver the plane out of the stall. The Airbus dual and un-linked mini-sticks philosophy led to the deep stall and spin (the young pilot kept pulling full aft canceling the action of his captain thanks to the AVERAGING LAW governing the sticks input – this is total madness by the way and similar to AF447 nearly a decade ago showing clearly that nobody care much at Airbus about previous experiences).
– Once in an unrecoverable situation, both pilots were still acting under the LIMITATION of a flight computer that HAD NO VALID CONTROL LAWS to manage the situation since this flight SITUATION is not FLIGHT TESTED. I fail to understand Airbus logic here.
– The Trim circuit fault rooted from an incident report dated from 1993. No proper action were taken by Airbus to successfully tackle the source of the problem despite the relatively basic complexity of it. Could it be the sign of a deliberate choice to keep an outdated process in the loop only to increase the turnover rate of that part and increased its profitability (see cost/year of a typical CN). I wonder if this is specific to this A320 series. What about the A330 or the A380?!?
[ATTACH=CONFIG]242439[/ATTACH]
– The related maintenance manual is a mess with addition being piled up during the years without any deep rewriting. This imparted IMOHO the maintenance crew to have a deep understanding of what proper actions could have been taken before the event (read it by yourself in the annex, it’s full of loop, redundancies and non-specific instructions). At the age of high turnover in many industrial process (part related), any Technical documentation MUST put the emphasis in having a pedagogical content.
– there are some troubling confusion in the teaching material b/w what is a stall and how you might enter a spin during a stall recovery (you certain don’t need to take roll action to get out of a stall even if you are in a bank turn). Coincidentally, the FAA issued a revision of its “Stall Prevention and Recover Training ” on the 24th of November:

To conclude, AirAsia crash reflects a systemic failure (design, SOP, maintenance and formation) and this ONLY should fill the content of a serious news article. Because the doubts raised today makes air traveling really scary…*
A thought for all the dead and their families. Once again, hundreds of people confident in a system that prized itself for its culture of safety died in an horrible agony after having to endure a 3min long terrifying plunges toward the ocean.
Note:
The above news article is extracted from http://www.aeronewstv.com/ but could have been from CNN or some other major media.
It’s a shame for the industry (and journalism perhaps) that we have to read this!
So yes, as we are reaching Christmas, let’s say that an Airbus should make for a nice toy for any fan of simulation with plenty of buttons to click-on with an automatic death sentence to fear in case the right sequence is not entered correctly…but not so much IMOHO in a real flight where the culture of safety is an integral part of performances.

*At least with planes designed by this manufacturer. But given the silence of the ICAO and the trend of outsourcing parts with identical subcontractor, this in effect, tarnish other.
Air Transportation Director General Suprasetyo said the inspections of the A320 fleets began Thursday, and that planes would be allowed to continue operations during the inspection. Mohammad Alwi, director of airworthiness and aircraft operations, said inspectors would check maintenance and operation records for any signs of trouble, even beyond the rudder system.
“Our inspectors will physically check the RTLU. We will open the panel, even if the records do not indicate any problem,” he added.
As a side note to the topic handle:
FCTM – Side-stick and takeover Priority Button
When the Pilot Flying (PF) makes an input on the sidestick, an order (an
electrical signal) is sent to the fly-by-wire computer. If the Pilot Not Flying (PNF)
also acts on the stick, then both signals/orders are added.
Therefore, as on any other aircraft type, PF and PNF must not act on their
sidesticks at the same time. If the PNF (or Instructor) needs to take over, the PNF
must press the sidestick takeover pushbutton, and announce: “I have control”.
If a flight crewmember falls on a sidestick, or a mechanical failure leads to a
jammed stick (there is no associate ECAM caution), the “failed” sidestick order is
added to the “non-failed” sidestick order.
In this case, the other not affected flight crewmember must press the sidestick
takeover pushbutton for at least 40 s, in order to deactivate the “failed” sidestick.
A pilot can at any time reactivate a deactivated stick by momentarily pressing the
takeover pushbutton on either stick.
In case of a “SIDE STICK FAULT” ECAM warning, due to an electrical failure,
the affected sidestick order (sent to the computer) is forced to zero. This
automatically deactivates the affected sidestick. This explains why there is no
procedure associated with this warning

NTSC Final report QZ8501 p79
” A crack in a tiny electronic module caused the system to send repeated warning alerts to the pilots, who responded by resetting the system.”
A fault like this could be due to bench testing showing NFF (No Fault Found) as the unit was probably not stressed by heat or cold on the bench as in the air.
Had lots of problems with Jindivik Transformer Rectifier Units until luckily found water across a couple of junctions. Normally this water would evaporate before being able to inspect item. This led to a change in design of the cooling air inlet!

Goof hypo but Airbus Engineers were way aware of the concerns. It’s a problem of decision takers…
Extract from the NTSC:
According to the Airbus information, there were three Technical Follow-Ups (TFUs)
regarding the AUTO FLT RUD TRV LIM 1(2) (SYS) problems that were issued
since 1993. TFU No. 27.23.51.004 was opened in 1993 regarding the problem of
fatigue rupture of solder and closed on 1996. The problem found was “fatigue
rupture of soldering” and the improvement made was “new electronic module”.
Another TFU 27.23.00.004 was opened in 2000 with the same problem of “Rupture
of soldering” and closed in 2014 with the improvement of the “Electronic board
process” which was available since 2002. The third TFU (number 27.23.00.007)
“Mechanical stop failure” was opened in January 2015 following this accident.
Airbus informed that the installed RTLU on PK-AXC had been improved with both
Technical Follow-Ups (TFUs).
In other words: no conclusive actions were taken on that point since the problem was first discovered in… 1993.
Points Of Interest:
The aircraft operator advised the KNKT that the flight crew of PK-AXC had not
received the upset recovery training on Airbus A320 training simulator.

@nJayM:
No, I hadn’t found a copy of the report so far and haven’t read it yet. This is why I restricted myself from any comments.
You can find it here: NTSC final Report QZ8501 AirAsia Crash
Media reports are indeed troubling:
– the repetitive occurrence of the trim rudder failure
– the fact that the failure is an aggravating one instead of being tempered by a mechanical action (like the canards on the Gripen that switch to passive mode in case of damages – see also the rear CG of Airbus planes and the Pull down order of the Captain [?] ).
– The dual control stick with no linkage (again) and the fact that there are still no forced travel coordination b/w the two set in 2015! (a cheap upgrade)
– the Similar presence of a young Fr pilot behind the yoke that still point toward a lack of relevant screening process for trainee (add the Germanwings crash). Thank you for bringing up the apparent relevance of the Stuntman thread
– The fact that some major Media insisted on the pilot error when the mechanical fault and apparent weakness in SOP generated this disaster first (CNN)
Thinking more into the concept, I think a flying flight simulator could come around easily. Systems emulation, adaptive control laws and virtual trafic are now notions that won’t afraid anybody anymore speaking about it. The new key is now to have a low kinetic “situation” simulator to emulate the most hairy critical situations that a pilot now must have to be trained to deal with.
With crash safety design solutions and some other new minded approach, it should be possible to have a safe enough plane offering high sink rate and able to emulate the experience of a deep stall, a flat spin or a crash landing with enough safety and acceleration control to have an Instructor on-board teaching and screening several dozen of trainee at a low cost (before he had seen enough and decide to move on).
This kind of flying kinetic simulator (fitted with the above described virtual rendering systems (trafic, FCS systems and ctrl laws)) could be part of a mandatory session to all trainee with refreshing cursus in place for experienced aircrew.
It’s easy to foresee an economic model around it with the design fulfilling an international RFP (ICAO for example) and the plane being bought by individuals or structures renting hours to companies or professional flying school (just like the NATO’s pilot training system in place).
With such a tool, sensations could be safely introduced in the cursus, adding a new dimension to the training that will bring in a much needed awareness for the pilots encountering a critical situation.
Low kinetics is the necessary variable to emulate safely on a regular basis an abrupt flight departing, a high pitch rate (periodic or pulsed), a high drifting angle, a high sink rate and, of course, the most dairying crash landing training.With such a tool (and added hardware), we can even envision to train (via flying simulator as opposed ti ground based one) for landing on forest canopy, crash landing at sea, take off and landing in icy/ or heavy snow conditions, extreme cross wind landing and of course, power-off approach (tracting engine at full power for safety – not even at idle).
NASA Brings Fused Reality Simulation Into Cockpit
NASA also wanted to evaluate use of Fused Reality for a landing task requiring a high glide angle to touchdown. This could not be tested using NASA’s F/A-18 because the aircraft would not be able to arrest its descent rate fast enough to recover. “We could simulate a runway at 5,000 ft. above ground level and fly a very steep approach to touchdown. The aircraft would flare to touchdown and fly through the virtual runway, but that was OK,”
Here we are… now where is my low kinetics flying mule?
