Jet2 emergency descent and diversion

[sonicwave]

Jet2 in the news : Second emergency landing for Jet2 plane in two weeks - BBC News (http://www.bbc.com/news/uk-england-40763488)

Jet2 is quoted as saying "and at no point was the safety of passengers compromised."

Surely thats a bold faced lie ?

An 'emergency' descent, oxygen masks deployed and a diversion; by any definition that is less safe than the intended, uneventful flight. So safety indeed WAS compromised.

[Brigantee]

What's the issue?? The masks deployed as they should ...had they not you may have a point, However as it is your talking boloxs..sorry

[Piltdown Man]

Had the oxygen masks not worked and the pilots not initiated a decent then that would have compromised the safety of the passengers. What was compromised were the passengers' plans, the profitability of the flight and this aircraft's schedule.

sonicwave you will soon find out that the experts on this site do not make new posters very welcome and try to ridicule them.

I'll tell all of you that I wouldn't feel 100% safe in a 31 year old 3rd hand aircraft that seems to go wrong too often.

[Piltdown Man]

OK VC10, please tell us how many people have been injured in these 31 year old, 3rd hand aircraft operated by Jet2. I think it's less than one. Ridicule? No, we'll leave that for your next post, unless of course you can back up your comments with hard facts. As for a welcome, well that depends. If anybody makes a post based on fact, an opinion based on science or posts a genuine question then they are treated appropriately. But the line "Surely thats (sic) a bold faced lie ?" deserves a reply. As does your comment about an aging aircraft. So tell us, are you a qualified engineer or just a troll?

[VC10man]

You see sonicwave I'm right. Just come out with an opinion and the thought police come and get you.

Piltdown you know as well as anyone that these planes are past it and however well they are maintained they needed replacing a few years ago. Oh and do you have to be a qualified engineer to post on here?

Your remark about being a troll just sums you up.

[Johnny F@rt Pants]

How many times does age crop up??Age has nothing to do with it, it's the number of cycles that count. These aeroplanes have been well maintained whilst at Jet2, and I have no doubt whilst they were at their previous operators. This is a very unusual instance where the same aeroplane has had the same type of problem in the space of a couple of weeks, but I can reassure you as one who flies these aeroplanes, and as one who sits down the back with my family regularly that there are no reasons not to.

Just come out with an opinion and the thought police come and get you

They come and "get you" when your opinion is based on no experience or knowledge of the subject matter, it is pure speculation based on having read bullsh1t in newspapers and on websites where equally ill informed bozos make mountains out of molehills and report utter tosh.

[simmple]

Well maintained, well built 31 year old aircraft have stood the test of time and are probably just as likely to break as the new generation of poorly designed, cheaply built ones!

[VC10man]

Are you saying that the Boeing NG aircraft are not very good?

[Check Mags On]

Doesn't have to be old to have a pressurisation problem.

Well this one was two weeks old at the time of the incident.

@Brigantee and Piltdown

I'm amazed you think that there is no issue with an emergency decent and O2 mask deployment. I for one WOULD be worried and would want more than someone in the cockpit telling me that things were ok and not to worry. If there was NO issue, why the rapid descent, why the O2 mask deployment? Only AFTER the fact can you KNOW there was no issue.

I suppose you also think battlefields are safe because not everyone gets hurt (or worse) and the generals keep saying don;t worry son, I know what i'm doing, you'll be ok

[Piltdown Man]

There was clearly a problem and possibly both incidents were related. But maybe they were not. Maybe it was the age of the components, maybe not. But unless we have more facts we won't know. But what is for certain is that Jet2 have good engineers who will not knowingly sign off an un-airworthy aircraft.

So given a pressurisation problem (finger trouble, bleeds, packs, controllers, ducts, electrical wiring, dump valve etc.) what do you expect will happen? Let me tell you. Firstly the pilots will put on their masks. An emergency descent will then be initiated. When the cabin altitude exceeds 14,000' or so the masks will deploy. Now the panic starts in the back. It's now traditional to think you are going to die and some people must scream, even if just for effect. But two people at the front will be executing Plan B or even C, one of the ones they were thinking about before it all went wrong. When that is underway they may even tell the passengers what happened. But they will not be believed even if they were listened to. Notice, the last people to hear what's going on will be the passengers - as it should be.

After the inevitable diversion (not 'emergency landing', whatever one of those is) the plane will probably be grounded, even if just for the local authorities to have a poke about. But the news of what happened will come from the passengers, the ones who thought they were going to die. Facebook and other social media will be filled full of tripe even before the plane has landed. The press and TV will do a yet another emergency landing (not diversion), passengers barely clinging to life, nearly crashing stories; without doing much in the way of research. They may even interview an idiot who was on the flight for effect.

Unsafe means there was danger or the risk of injury. If the emergency descent was not performed AND the masks failed to drop then that would have been unsafe. But both occurred. So based on what you believe, you'll be better off not flying. Events such as this happen to new and old aircraft. So you had better find a safer form of transport because flying will never be safe enough for you.

Well. Said.

[DaveReidUK]

not 'emergency landing', whatever one of those is

I'd say that "landing after having declared an emergency" was a reasonable definition. :O

[Piltdown Man]

DR - Fair enough. So what sort of landing is one that follows a PAN? And is a landing following a low fuel Mayday an 'emergency landing'? Thinking more about it I feel an 'emergency landing' is one where the outcome of the landing is in doubt.

[Chesty Morgan]

This was an emergency descent followed by a diversion followed by a normal landing.

The emergency was over at the point they reached breathable air.

[HamishMcBush]

I'd say that "landing after having declared an emergency" was a reasonable definition. :O

Far better than "Failing to land after having declared an emergency"

This may come as a huge shock to you but aircraft are complex machines that can and do go wrong no matter how well maintained , Its what machines do im afraid

So in their wisdom the clever chaps who design these complex amazing machines we all take for granted provide us with safety nets when things occasionally do go peak tongue



In this case there was a problem with the pressurisation system (which is there to ensure we are flying in a cabin that's at around 8000 ft whilst the marvel of engineering we are in is actually at a much higher altitude) in the event that for whatever reason the cabin altitude starts to climb above that figure then fear not those clever designer chaps provide us with drop down o2 masks with a completey independent self generating o2 supply for each and every pax which will keep us from turning blue whilst the pilots reduce the aircrafts altitude to one which is suitable for us humans to survive, And it worked perfectly as intended

So whats the issue FFs ?
