Thread: Plane Carrying 133 Crashes In China, Causes Mountain Fire

^ Less than two minutes to work out what is going on and find a solution. No solution and you die. Some sort of stability is required before you call in the emergency.

Not being an expert in the subject I don't know. but I am willing to take a guess and say that in that situation a Mayday would not have helped and it could have hurt.
So that might be another reason why one was not made.

It depends. In an emergency situation, calling for help can be invaluable. I've watched shitloads of flight crash docs and its rare to hear nothing from the pilots. The tower was calling the plane as it started to descend on radar. You are supposed to reply if you can.

This from the guy who thinks speculation is fun when people die.

Back off and allow those with genuine knowledge and experience do the speculation. Watching crash documentaries does not make you an expert. You have no place here with such a cavalier attitude to the untimely death of strangers.

Skidmark is a witless fucktard with the intellectual capacity of a retarded amoeba. Better not to engage.

Thick as shit and trying to pass off internet opinions as his own?

Yup.

This was stated and brought to the forefront immediately after the crash. Please up your game.

^^ A suggestion that a max fcc was fitted to an ng?
I don't know if they are interchangeable.

My experience has been that where boxes are interchangeable between different variants the software gets a hardware input to indicate configuration. Where there is a conflict between SW and HW you get a nogo on power up. That happens even in risk class 3 SW let alone class 1.

Even if it were possible the aoa indicator is only an option on the ng and mcas would be Inhibited. Even if that was screwed up then the stab trim cut out switches work differently on ng and problem can be inhibited and still use trim switches. Then we have the aircraft in autopilot where mcas is inhibited.

That's a lot of reasons to think it isn't likely...

You didn't finish the article.

Which the article then goes on to do by theorising about the accident being caused by some software upgrade or other.

1. Hoohoo posted it.

Nine days after the crash and the chinkies have just seen fit to issue visas to the NTSB team.

Plenty of time for the chinkies to try and sanitise the crash scene of course.

And if they haven't finished, they can always play the quarantine card.

2-3 weeks . . . wankers

I had a check this morning and found the following link that provided the software upgrades for the FCC:

Automatics - An illustrated guide to the different MCP's & autopilots used on the 737

If you go to the bottom of the link then you will see there is a maintenance page with a BITE test for HW part number and FCC OPS SW number. These will need to match for the BITE to pass so it is as I expected.

There's been a lot of changes since I last worked on a 737, which was the Classic 3/4/5 series. I haven't seen the Collins MCP before, only the Sperry SP-300 AFDS, so I am out of touch with the later Boeing designs.

Reference the NTSB, I believe the quarantine aspect is still under discussion:

I expect that China will provide the NTSB with the FDR and CVR data anyway, it will only be a problem if this data is unreadable.

FTFY.

I'm not sure such distrust in the Chinese aviation authorities is warranted. Previous airline accidents in China have attributed pilot error and maintenance error where appropriate.

I am expecting the preliminary report to be an accurate account of events leading to the accident.

Just like the COVID outbreak.

Don't know much about Chinese modus operandi, do you . . .

Its one thing covering up issues like COVID and human rights etc in their own country but they have to operate their airlines internationally, failure to disclose the cause of accidents will have consequences for their ability to operate in others airspace.

The CAAC have been very open so far. It is in everyone's interest to find out what happened. The Chinese have a huge fleet of 737s so they want to know if there was anything wrong with the aircraft, with maintenance, or with their SOPs.

I don't expect information leaks that are so common in the West. If there is anything found to be wrong with the aircraft I expect Boeing to be informed immediately.

I guess I have a little more faith in icao procedures than others.

Exactly.-And even if they can’t, they will!

BEIJING, March 31 (Reuters) - The cause of the crash of the China Eastern Airlines (600115.SS) jet last week must be determined as soon as possible, state media said on Thursday, following a meeting of China's highest decision-making body helmed by President Xi Jinping.

I.e. before the experts arrive and the truth comes out.
