Flight incidents

My understanding is that airline incident investigations and consequent safety standards are the best there are.  They are used as a model for incident investigation in many other industries and services.

The line of accountability is quite impressive, every single screw and small component has to be signed off as fit for use and leaves a paper trail all the way from instillation to designer so if something does go wrong you can find out exactly where and who's door the blame lies at. 

Am always fascinated by people's backgrounds on here at times

Mind me asking how you're aware of things sort of thing - Is it purely through interest or genuine work?

Work, I did when I first left uni, freelance work as an aerospace engineer ( which my degree is in) got contracted to look at blackbox data and correlate the data to speculate on areas of failure.

How many black box data analysts are there ? 

Like I say I was working freelance so I'm not sure exactly how many and that depends, if it goes to the manufacturer or one of the investigative labs but it's usually a quite large team  and then sometimes they outsource the data after they've come to the own conclusions to people such as myself to verify their results and see if we catch anything else, I had to sign NDAs though.

One of the cases which isn't mainstream and I can talk about because they didn't make me sign an NDA, they gave me data on a single stage jet turbine but there was data missing ( pretty sure deliberately because I worked out what it was afterwards anyway and the issue was a known fault on that engine under extreme stress, anyway ) I had to correlate the rest of the data on how the engine was performing, for example at different RPMs, its compressor and turbine effeciencies (which at a specific RPM dropped to - 5% so you can see the problem here) so then I had to look at the other data at that specific RPM all across the heat cycle, which led to the problem being the fuel flow valve failing which flooded the compressor, choking the engine to death.

Just to make everybody feel all the bit safer, it wasnt for a commercial jet, it was for an BAE testbed prototype which they were stress testing. 

Would such a rapid descent knock out the people on board?

I remember watching a program on sky one called the Day Britain Stood still. Probably about 15 years ago now. The premise was that a couple of accidents at certain points on the M25 would result in Britain being completely choked. At the end it resulted in air traffic controllers being unable to be relieved and therefore suffering from fatigue which resulted in a mid air collision at 15000 foot over Gatwick. Apparently in a mid air collision one plane usually disintegrates and the other falls out of the sky with a plane size hole in it. It said that at 15000 feet you'd still be conscious when you hit the ground.

Happy new year

10,000ft in a minute! Blimey

I've just done the maths. 
.It would take Watson 17 months 

What the hell do they do in Indonesia? Apparently it's the 7th crash killing 50 or more people in the last 15 years!

Barely a year passes without some kind of plane crash/incident there.

All Indonesian planes were banned from Europe for quite a few years due to their poor safety records

To expand upon this in the past its been found that their maintenance staff didnt inspect their craft to the standard expected in the EU, one of the other reasons they were banned

Thinking of starting a thread. 

How did you feel when your dog got run over. 

Ruff

Bit like the joke... What does a Cat sound like when its been ran over - MEEEEOOWWWWWWWWWWWW

Sorry to derail the thread!!

Discussing plane crashes is one thing, but train crashes... on a Charlton forum of all places... too sad, just too sad. 

When you watch Air Crash Investigation it always seems that a series of issues cause a plane to crash.

I can tell you what they do. They ignore safety procedures. They don't believe in worrying about it too much. I lived there for a year and took many internal flights. I'm surprised that there have only been 7 crashes in 15 years. I remember one particular flight during which I was constantly looking around me wondering where the open door or window was.
Of course you don't hear about their road accidents, sinking boats, exploding ovens etc.
I had a fun 15 months though.

Actually I've done a bit of research into this as I have a scene in my novel that required it.
You would be conscious when you hit the ground but you wouldn't feel anything. This is because of the time it takes for the feeling of impact to reach the brain. An impact which would result in certain immediate death cannot be felt.

But nobody can really know that for sure.

They’ve found wreckage and body parts in the Java sea. Most is 75ft below the surface and they are trying to recover an emergency signal.

That's 7 crashes in 15 years in which 50 or more people have died.

There have been many other crashes.

In all of these, people survived thanks to Allah.

Slightly off topic, but an interesting tale - in the early 1980’s my mum had a Boeing 757 named after - her husband was finance director of Air Europe - the airline was part of Intl Leisure Group, which also owned Intasun and Club 18-30 - they flew to the Boeing factory to pick up the plane, and she poured champagne over the nose - its registration was G-BPGW and it was called Anne Marie - they were presented with silver ignition keys by Boeing and she started the engines - she gave me one of the keys for my 50th birthday last year - key and the actual plane below - it’s not flying anymore - scrapped a few years ago
