t
they are a cost to be mitigated with things like P2F.
Agreed. There is only one way to fight bean-counters, by making their business model unprofitable.

You could start with this...

Pilots involved in P2F should not be called professional pilots, because the definition of professional is being paid to do a job (in your profession)..."not paying to do your job"!

During in-flight introductions they should be introduced as such. ie... cadet pilot, amateur pilot, or pilot in training.

I think the PAX have a right to know, and just maybe, just maybe it might raise some eyebrows. Or make some feel uneasy, and choose another airline next time.

About the captains military experience.
It's difficult for western pilots to understand how some air force fighter pilots from some South East Asian countries can leave the service with very limited flying skills.

Speaking in general terms, not saying that was the case with this AirAsia captain.
Any information on his age?

Bud Leon #1088 and others: ICAO has a handy tool for comparing air safety capabilities of different states at http://www.icao.int/safety/Pages/USOAP-Results.aspx. It’s based on very thorough, independent audits.

Before making sweeping comparisons between Asian and “Western” safety regimes just note that Singapore is one of the few States with a near perfect score and China is almost as good. Malaysia is much on a par with Australia and well above the international norm. Sadly Indonesia lags badly and theirs is very recent audit. So I fly on AirAsia’s Malaysian registered planes but not on those of its associates.

Interestingly AirAsia X Indonesia was due to start direct flights between Melbourne and Bali on 26 December but postponed the service at very short notice. Does anyone know if there were problems with the airline’s technical readiness?

@mary meagher

In dangly engined jets at low airspeed, and therefore low aero forces, extreme pitch up with high power has happened many times. Not all were so fortunate as in the example illustrated.

Budi Sampurna, a professor at the University of Indonesia and member of the forensic team responsible for identifying bodies from the crash, said one autopsy had already taken place, but he didn’t comment on the cause of death. He also didn’t say how many other autopsies were planned.
via the Wall Street Journal

just to confirm autopsies have been performed

53 IIRC.

@chefrp I wish it were that simple. The flying public has shown time and time again that it will do anything to save $5. Even if saving that $5 costs them $50 in fees. What you're proposing by implication is an education campaign by pilots that has a steep hill to climb in convincing people that safety is worth a little extra. People will cram themselves into 28 inch pitch seats over a few dollars. If they won't pay a bit extra for their own comfort, the statistical unlikelihood of an accident makes it unlikely that they will pay for an extra safety margin.

Times Strait reports:

PANGKALAN BUN/JAKARTA – Indonesia’s transport ministry will investigate all Indonesia AirAsia flight schedules from Monday as part of a government probe into Flight QZ8501 that went missing almost a week ago.

This comes as the ministry said flight QZ8501 was on an unauthorised flight schedule because the airline was only permitted to fly the Surabaya-Singapore route on Monday, Tuesday, Thursday and Saturday. Flight QZ8501 took off last Sunday and the airline had not sought permission to change its schedule prior to the flight.

“We are going to investigate all AirAsia flight schedules,” said Djoko Muratmodjo, acting general-director for air navigation in the transport ministry. “Hopefully we can start on next Monday. We won’t focus on licences, just schedules.”

“It might be possible to revoke AirAsia’s licence in Indonesia,” Muratmodjo added.

The transport ministry suspended AirAsia's Surabaya-Singapore route on Friday. "AirAsia's permit for the route has been frozen because it violated the route permit given," he said.

The airline said it would cooperate fully with the investigation and would not comment on the matter till the investigation is completed.

The ministry said "customers who have booked AirAsia's Surabaya-Singapore tickets should be compensated with other airline tickets as per the existing regulation."

Just to second that it seems autopsies are being done, just not on every body. Which is understandable given the circumstances and in some cases pointless.

AirAsia flight QZ8501: Another 12 bodies sent to Surabaya hospital for identification - South-east Asia News & Top Stories - The Straits Times

Autopsy will be performed on some of the bodies to support an investigation into the crash, Xinhua news agency quoted head of the Disaster Victim Identification (DVI) center Budiono as saying.

"Some of them will be autopsied to find out the cause of the accident," he said at the Police Hospital Bhayangkara in Surabaya, the provincial capital of East Java.

"We will conduct autopsy at least on bodies of the pilot, co-pilot,'' he was quoted as saying.

that will save a lot of time on tedious investigations.

Thank you, Dave Reid, for that very useful link to the full UK AAIB report on the Boeing 737 stall - a full stall, NOT just the approach to the stall - that took place on approach to Bournemouth on a flight from Faro on 23 Sept. 2007.

As nobody got hurt and it was early in the day at a quiet airport, the details of the incident got lost in the bureaucracy, and only a sharp eyed chap in the back office flagged up the true significance. By that time the airliner and the pilots involved had been flying as usual, for several weeks, without sharing the experience with the authorities....which means the Black Boxes had gone on to other things. However the pilot did talk to the company engineer, who assured him the data had been saved on the OFDM, or operational flight detail mentoring, which was sent to the company by mobile phone. And THAT's how the scary charts and details were saved and then studied by the AAIB.

Quite simply, they didn't monitor the airspeed. The auto throttle had disconnected and the warning light wasn't noticed.

And as Jimjim has posted here, if you intuitively apply FULL power, underslung engines can tip up the aircraft so that the elevator is not so effective. A balance has to be achieved, by using trim, power, AND elevator to recover from a full stall. Airline pilots reading this, please have a good look at that AAIB full report referred to by DaveReid. It was not an Airbus, it was an elderly Boeing. and it was not an Asian Airline, nor overly deferential Asian pilots, they were both British, well trained and fully experienced.

They probably overlooked the inconspicuous warning light on the Boeing panel that the autothrottle had disconnected. With everything hanging down, the engines, the flaps, the spoilers, here goes the STALL STALL STALL noise, and what do you do 800 feet from the runway at a speed of 82 knots? Well, it pitched up 33 degrees, they did very well to go around.

All in a day's work. But what is different about having everything go pearshaped in a Cunimb at 38,000 feet? Should have plenty of time to sort things out, and those who fly in these latitudes are experienced in interesting conditions.

An eerily similar event took place by Iceland Air in Oslo, Norway, a few years ago. They came in for landing and messed up big time. Many passengers had brown pants... Capt didn't report it as he should have, it was only by reading out the FDR due to some other trouble that the incident was discovered (as I recall it...). I have the report on my computer somewhere but can't seem to find it right now on the Internet. You can look for it here:

From one Monkey to another.

" Is there anyone on this thread who actually wants to discuss about AIR ASIA QZ 8501??"

My gut tells me we are. I hope I am wrong but time will tell.

Coincidentally a very interesting discussion on BBC R4 this morning from the author of "The Glass Cage" concerning man's interaction with automation - listen to the end to hear quite a lot about aviation.

Here is the link - start listening at 1.20.55:-

Presumably the reports that they had no authority to fly that route are just a red herring, or is there a suggestion that as the paperwork for the flight schedule is not correct there may be other issues with paperwork?

Equally how did the Indonesians allow the flight to be booked, and depart etc as after they must have known it was happening.

Looks like they are getting close to the main wreckage field

Indonesian officials said Saturday that they were confident wreckage of AirAsia Flight 8501 had been located after sonar equipment detected four massive objects on the ocean floor.

The biggest piece, measuring 18 meters (59 feet) long and 5.4 meters (18 feet) wide, appeared to be part of the jet's body,
“I can confirm that these are parts of the plane we are looking for,” said Bambang Soelistyo, head of Indonesia’s National Search and Rescue Agency.

Search teams again battled high waves and struggled to lower a remotely operated underwater vehicle to capture clearer images of the objects on the sea floor at a depth of about 100 feet.

AirAsia was limited slots due to nearing it’s quota for flying people to Singapore

Fox News reports:

"So AirAsia has committed a violation of the route that has been given to them," Barata told The Wall Street Journal. He said the company's flights from Surabaya, Indonesia's second largest city, to Singapore had consequently been suspended on Friday.

AirAsia used to have permission to fly the route daily, but the number of slots was cut for the period Oct. 26 to March 28 because the country was nearing its quota for flying people to Singapore, said Indonesia’s acting director general of aviation Djoko Murjatmodjo. He didn’t say if other airlines also had their slots reduced.

Murjatmodjo added that AirAsia had been flying the route on Mondays, Wednesdays, Fridays and Sundays rather than the four days designated by the Transportation Ministry. He said the ministry is investigating why AirAsia was flying the route outside its permitted schedule. The probe will include an investigation of the ministry.

"Frankly speaking, it's a bit late for us to find out about this," he said. "One thing that's certain is the days that they are flying aren't the same as the days they were given. There was no request for changes."

Sounds a bit political to me more than regulatory.

AGAIN, any airbus guys ...CAN THE PLANE JUST HOLD PITCH AND WINGS LEVEL BASED ONLY ON GYRO AND NOT WITH AIRSPEED OR ALTIMETER INPUTS?

and

underslung engines...well a long time ago most of us realized that if you add power the nose goes up

so, throttles forward, stick forward and everything is dandy
