Hi Guys - been awhile since I was here
Thought it was time to change the flow of things on here
Seems rather boring and same old same old going on
How about a tread with some issues that are/will affect us all.
Everything is getting pretty bloody ugly out there.
Middle East invasions and intimidations ?? Maybe not, maybe yes ??
Europe central bank – federal reserve – who owns them ??
Ordinary working people getting treated like morons - or perhaps they are becoming morons ???
Thoughts please
Thought this chap might be me old mate Mike – sure makes sense like he used too.
Shortly after takeoff on 4 November 2010 from Singapore Changi Airport at about 7,000 feet, a loud bang was heard in the cockpit of Flight QF032, followed by indications of a failure to the No 2 engine. It was subsequently discovered that the RR Trent 900 engine’s IP turbine hub had broken into several large pieces which caused significant damage to the wing and to a number of systems of the A380 aircraft. Minor injuries occurred to some people on Batam Island in Indonesia as debris from the aircraft rained down.
The Captain, Richard de Crespigny, held the aircraft at 7,000 feet. It soon became apparent that auto thrust had failed. Indications of No 2 engine overheat, and subsequently of fire, were dealt with but there was no confirmation that the fire extinguisher had discharged. After discharging the second fire extinguisher without confirmation, the engine fire warning was replaced by an overheat warning. A PAN call was made. The Captain placed the aircraft in a holding pattern close to the airport while First Officer Mathew Hicks, dealt with more than 50 messages on the aircraft’s systems monitoring and alert system.
The list was considerable:
The No 2 Engine display showed a ‘failed’ mode, while engines 1 and 4 were in ‘degraded’ mode
The green hydraulic system indicated low pressure and low quantity and the yellow hydraulic system indicated engine 4 pump cautions
AC 1 and 2 electrical bus system indicated failure
Flight controls were in ‘alternate law’
Wing slats were inoperative, spoiler control was reduced and aileron control was partial
There were numerous warnings for landing gear control and brake systems
Autothrust and autoland were inoperative
Error messages for engine anti-ice and air data sensor were displayed
Multiple fuel systems errors including fuel jettison fault and centre of gravity messages were displayed
No 1 engine generator was disconnected
Left wing pneumatic system was leaking
Avionics system overheat warning was displayed
S/O Mark Johnson, went to the cabin and saw that the fin camera display showed a significant fuel leak from the left wing. As the fuel dump and transfer systems were unserviceable, the aircraft was moving towards both longitudinal and lateral out of balance. The Captain decided to land 50 tonnes overweight while the aircraft was still within the C/G limits. After computing several options with different configurations, a landing calculation was found that would permit a landing on runway 20C with a 100m margin.
F/O Mathew Hicks handled an unprecedented array of failures in an aircraft with great systems complexity.
S/O Mark Johnson established voice communications with Qantas engineers in Sydney through a mobile phone after failure of the aircraft’s satellite voice link.
Training Captain David Evans and Captain Harry Wubben, who was undergoing training as a Training Captain, made valuable contributions including visual inspections from the aircraft cabin, communication with cabin crew and passengers and assisting with calculation of overweight landing performance with the damage to multiple systems.
After controllability checks, the Captain commenced a 20nm final approach to runway 20C with the No 4 engine set to the same thrust as the No 1 engine while using only the No 3 engine for thrust control. After the autopilot disconnected twice, the Captain flew the approach manually from 1,000 feet. After touchdown, full reverse thrust was applied to No 3 engine, however, maximum braking could not be applied until the nose wheel had touched the ground. The landing run was completed about 150m from the end of the runway.
After completing shut down checks, the crew were informed by the fire crew that the No 1 engine was still running, even though there was no instrument indication of the engine running. Despite numerous efforts, it proved impossible to shut down the engine by normal means. The fire services were then requested to drown the engine. All the passengers were then disembarked without injury.
For their safe handling of an unprecedented set of failures, sound decision making in an extremely complex emergency and superb handling of an aircraft in extreme circumstances, saving the lives of all on board, the crew of Flt QF032 are awarded the Hugh Gordon-Burge Memorial Award.
Very cool account, Ivor. I didn't know these details.
I guess that most people who registered the news of the accident fell into two camps: those who are scared of planes and always suppose the worst, and therefore see this flight as having been very lucky; or those who know that the scheduled flights of major airlines in the 21st century have an awesome safety record, and therefore expect that a jet has very good chances of surviving an engine failure.
I was in the second camp, until a day or two after the accident when I read how many systems had been disabled by the explosion. That they were on the way to exceeding CG limits is complete news to me. The flight crew well earned the Award -- they were disciplined and skillful in a situation that could easily have been a catastrophe. How they kept that ship on the runway, is miraculous to me.
Though the uncontained engine failure falls in the "should never be allowed to happen" category, and the 380 suffered plenty of damage, the airframe had enough strength and redundancy to get them to the airfield -- thank God they weren't in mid-ocean at the time.
When I had my first (and so far only) 380 ride a few months ago, I felt "safe as houses," and extremely comfortable as well. Both Boeing and Airbus are now running about 1 fatal accident per 3 million departures. Awesome!
@maxirat: The history of political discussions on this forum is pretty miserable. As to fiat currency, all of the modern world's reserve currencies are of this type, and people seem to like receiving them. To my mind, if one takes a step back and looks at the big picture, one system is about as arbitrary as another.
Even aviation professionals believed there to be an engine fire, or similar, that needed extinguishing or dousing and it became something of an amusement that the airport fire service had been called upon to actually drown the engine in to submission, I don't believe this has ever been called upon before.
It was caused/due to these modern technologies, fly by wire, computerised controls etc. whereas when the No.2 engine exploded it severed the controls to the No.1 engine and the No.1 would continue at the same speed/revolutions etc. as it had been at the time the controls were severed, the crew couldn't even cut off the fuel supply to it.
But the aircraft was, with fuel loss from one wing etc, heading for a position where it would fall out of trim and no longer be flyable, for the crew to elect for an overweight landing whereas the knew that they were going to use all but 100m of the runway, 100m is bugger all to a beast of that size, they could have waited longer to lighten the weight (by fuel burn and loss) but to go for a max runway length overweight landing can be taken as a sign of just how desperate they were to get that beast on the ground!
And had it happened way out over the South China Sea? ... It is likely that the aircraft would have fallen out of trim, become unflyable ... and you know what happens thereafter!
I stand by my words ... The smaller the aircraft, the more engines the better, then the better chance of survival one has and you won't find me anywhere near an A380!
Agreed, the part about needing to drown the engine was news to me, and quite astonishing.
In general, would mechanical throttle linkages would be more robust than FBW in the case of an uncontained engine failure? At least the FBW systems have redundant cabling along physically separate routes (supposedly), which is not practical for pulley-and-bellcrank rigs.
Meanwhile, maybe you could look into fitting 4 Gnome radials to the wings of a Cessna 150. The structure would need some stiffening, but with the extra 320 hp the added weight should be manageable. If two of them are mounted as pushers, that would eliminate the gyro precession effect :) This ship would carry its single passenger with an impressive margin of reliability!
In a more practical version of smaller + more engines, I recently had my first ride on a BAe146. It's a neat little airliner, and its quiet is noticeable.
The most amusing thing about the BAe146/AvroRJ is the noise the flaps make when retracting in the climb out after take-off, it's like something out of Star Trek ... "Warp speed Mr Zulu" or whatever. :)
I love to travel on Fokker70/100 aircraft, on aircraft I normally like to sit towards the back, but the travelling public generally don't appreciate that on the Fokker's there are no emergency exits aft of the wings hence why I normally sit forward of the wings on the Fokker's.
At the end of October I travelled on a B747, it's 21 years since I last travelled on a B747 ... give me an A340-300 anyday like the last time I flew to/from HKG with Swiss International Airlines ... But that said, this time, Cathay Pacific's catering is the best I have ever experienced, I was on the cheapest of economy tickets, on the B747 we had 2 choices of starter, 4 choices of main course followed by ice cream for desert with breakfast to be served towards the end of the 11.5 hour flight.
Expecting it to be a standard airline breakfast how wrong I was, this was a full blown 3 course breakfast with a choice of 2 main courses, in HKG I didn't even have time to finish a cup of coffee before it was onwards on an A330 to Cebu City, only a 2.5 hour flight, to be hit with another 3 course main meal and with a choice of 2 main courses. NEVER before have I vacated a flight feeling so full up. :)
Then, as Girl Friday and myself were departing Cebu for our home island on 04 November on an ATR72, she did the cross her heart thing on take off ... little did she realise the short runway length that we were flying in to, somewhat marginal for an ATR72 in these temperatures, that should have been the time she was crossing her heart. :)
But back to the A380 incident, it's never happened before so the good old-fashinoned mechanical controls must take the glory for this. Reminds me of back in the 90's, my cargo airline employee, we, then, operated DC8's, chartered in a B707 due to more work than we could fly ourselves. Well the B707 took off out of Belgium but somewhere over France one engine decided to fall off, not only that but it gave the adjacent engine a nudge on the way out and took that engine with it also.
So we had a 2 engined B707, no engines whatsoever on one wing, fuel pissing out of the wing, the wing on fire, no hydraulics etc. etc. etc. I heard this account from one of the crew members in an Oostende bar afterwards, the Captain got it down by throttling backwards and forwards on the two remaining engines, having declared a "Mayday" they were heading for the nearest French military airfield, without hydraulics they needed to crank the undercarriage and flaps down by hand, on approach the spewing fuel was setting fire to the hills etc. and whilst they managed to touch down near to the end of the runway they had no steering so the aircraft went it's own merry course across the airfield, the burning fuel following it, and by sheer luck they came to rest in what I can best desribe as a giant tray of cat litter designed specifically for such an incident and there to soak up burning fuel.
The French military really enjoyed it, they valued the emergency training that the incident provided, and unsurprisingly the crew went out with the French military and got totally bladdered. :)
P.S. Apparently John Travolta's B707 has changed from it's Qantas livery and was recently observed in PanAm livery for some film shooting somewhere near to NYC.
Mikhail Prokhorov challenges Putin. Prokhorov is majority stockholder of the New Jersey Nets. I didn't know the New Jersey Nets was owned by a Russian.
I don't doubt you, LR. But, I am skeptical. It is foolish to do to much research on this but I did Google "Al Gore is related to Stalin" or something like that and it produced no viable results. That fact is not that far fetched as Gore inventing the internet.
Facebook did do a study and they said everyone in the world can be connected by only four or five friends. In other words, someone you don't know, or even the president is a friend of a friend of a friend of a friend.
