Discussion On Planes & Aviation

[Guest dude]

more about the gigantic water pipe burst in Qantas QF94 flight to Melbourne, from Los Angeles.

[Hiboy]

And luckily it was fresh water flowing down on them and not other stuffs...

[Traveler]

Seems that Qantas is the only airline to have persistent problems plaguing its A380s. Maybe they need to to review their maintenance procedures.

[Enelym1978]

Actually SQ had a few regular issues with their A380 too.... we all know that the A380 is not the most reliable... I didn't say unsafe. It is safe but there are always small technical issues... My pilot friend from SQ told me...

 

B777 remains the most reliable so far for them.

[Channing]

ya i agree 777 is still the most reliable plane in the world

if not the OZ and MH accidents, 777 should have had no fatal accidents thus far

but this is kind of tricky as the ones that spoiled 777's safety records happen to be two of the world's best airlines... LOL

You need to qualify what you said about the two best airlines, MAS ( malaysia airlines ) and Asiana (South Korea' s No .2 airlines in terms of age and fleet size ).

 

 

Both airlines are quite different.

MAS received awards in the areas of inflight service being warm, genuine and going the extra mile to satisfy the passengers , most of the respondents like the satay served during mid and long range flight, but its management by quite a sad state of people who put racial color first over merit in the board of management, it was leaking losses like nobody's business,

 

 

 

Asiana wanted to be different form Korean Air , the imcumbent by having younger in flight crews, a swifter check in system, more use of internet booking and also routes that korean airlines did not fly too.

What has been repeatedly pointed out by external observers , that the Korean culture of deference to someone of an older age and seniority can sometimes and had beeen pointed out to be a cause of cockpit communication failures that can put plane passsengers lives in danger.

The end of AIRBUS is coming, since UAE airlines cancelled abig order of Airbus A350 planes and there are no new buyers for A350 from the major airlines recently in the Farnborough airshow, and Airbus is rolling out the refitted and reengined A330 neo series, soon Airbus will crumble under a mountain of debt from the failed A350 planes .

 

Bye bye Airbus.

 

they have not even reached the breakeven number for A380 planes yet.

Bye bye Airbus.

 

they have not even reached the breakeven number for A380 planes yet.

 

A further nailin the coffin for AIRBUS and its A350 XWB plane program is that Boeing is commited to providing 18Inches seat width to go with the New BOENING 777x planes seating 10 across with 18 inch seat width ,

 

trumping the A350s with 9 across seating with 18 inch also seat width, Boeing will beat Airbus to a pulp, 

 

You don't hear ads trumpeting about Airbus A350 18 inches seat width in economy, Airbus has suddenly gone silent , when Boeing announced that it will provide 18 inch seat width for the new 2020 launch date Boeing 777x planes that can seat more passengers and fly further on less fuel than Airbus A350's any of the models from A350-800,-900,-1000.

 

Looks like has no answer for Boeing 's  new plane, 

 

but then delivery date is still 7 years away for Boeing 777x , and it is heavily depended on composites like CFRP , carbon fibre reinforced plastics and carbon composite for the outer fuselage, we still don't know how reliable the composites are in ten years of service, it just takes one major incident that will happen , then we will really know how reliable the extensive use of CFRP plane parts. sad but true.

 

And Boeing 's new B777x has foldable wing tip for some models of its plane cause the wing is too long for some air port tarmacs and may hit and crash other parked planes on the tarmac, mechanical folding wing tips , Hmmmm......how relaible are they in everyday operations, will it come off unexpectedly will it ,alfunction at get stuck midway between midair and park position, we have yet to find out.

 

Plus the newer planes promises lower fatigue via less pressurised cabin and higher humidity for passenger comfort. Higher humidity is anthema to carbon composites , they can cause water molecule expansion during take off and landings , causing carbon fibers bounded by epoxy to fray .

 

There are still many question marks ??

SIngapore Airlines are gonna have sleepless nights, Etihad airways have launched their new livery and it looks fantastic, and the have launched new products for their first class and business class products for the ultra rich and those with bottomless pitof money,

 

DANNI MINOGUE, Kylie Minogue's lesser famous sister is the brand introducer for Etihads new launch of the current 2015 new products enjoy and dream of flying one day with Etihad airways.

 

 

 

The residence by Etihad, Italian design for everthing.

 

[Guest Guest]

THe new livery and the the new uniforms of Qatar airways,

 

 

Uniforms launches form 10.26 mins onwards.

 

Smart and contemporay , a departure from Emirates with some Middle Eastern acccents in theirs , Etihads are going ultra modern and the staffswill be so happy in their fashionable uniforms

 

[Guest Guest]

Sorry typo error , meant to say Etihad airways instead of Qatar airways.

[Guest Guest]

The UAE airlines QATAR airways and Etihad Airways, have launched fantastic new products recently ,if they improve on the infrastructure and software like cabin satisfaction for customers, Qantas and Singapore Airlines will find it hard to keep their Business Class customers from Jumping ship and abandoning QF And Sq in droves , if they have not already.

 

Qatar airways also launched newer and more luxurious products in their First and Business class products.

[Guest Guest]

SCOOT air to take delivery of New B787 Dreamliners this coming weekend.

 

I wonder how good is Al Jazeera's  report on the shoddy manufacturing of B787 Dreamliner that is plagued with all kinds of quality issues

 

 

[Guest wozzit]

Re the Taipei air crash, investigators hv studied the black boxes. They r now saying the pilots may hv accidentally shut down the wrong engine. They then tried to glide the powerless plane for 72 seconds. They may hv attempted to restart the engine but too late.

 

Both the pilots had thousands of hours flying this particular plane. Yet there hv been previous incidents on twin-engine jets where pilots hv suffered engine failure in one engine n mistakenly shut down the functioning one resulting in loss of power n a crash involving multiple fatalities. One featured in the TV series Air Crash Investigation. This involved a Boeing 737 in the UK trying to land at Manchester airport without power.

 

Investigators into the recent Air Asia crash say the plane gained height too quickly, was flying too slow n then entered a stall resulting in the crash. As many hv pointed out, that scenario is very very similar to the Air France A330 crash over the Atlantic in 2009.

 

What seems to link these crashes is their similarity to previous crashes. It makes me wonder if pilots of twin jets are routinely tested to assess how they react to loss of one engine n if they r briefed on other previous similar crash incidents. If not how long will it be before we see a twin engine wide body jet like the 777 in trouble after the loss of one engine?

[Phil]

Yes, pilots are regularly checked, and the tests often include engine loss simulation.

Nobody's perfect...

[Guest wozzit]

Nobody's perfect...

 

Agreed no ones perfect. But safety of the passengers is n must b a pilots absolute No. 1 priority. These 4 crashes killed hundreds of innocent people. If pilots make mistakes, then surely technology has to make certain these pilots know precisely what has gone wrong so they can correct the situation. Yet at least 2 crashes (n maybe more) hv involved senior pilots not knowing which engine has failed resulting in their shutting down their only operable one. So surely either training is not effective or the technology has to be improved?

Edited February 7, 2015 by wozzit

[Phil]

Sure, sure...

There is always room for improvement.

But in this last Taiwan ATR72 case, I think that human factors need more attention than technology.

Anyway, let's not speculate too much as long as the investigation is still going on. And there are certainly better aviation experts here than me...

From what we have so far heard, it certainly seems so.

Not speculation. Taiwan's Civil Aeronautics Administration (CAA) has ordered retraining for all 71 TransAsia pilots flying its ATR fleet. This will take about 4 days n has led to the cancellation of 90 flights.

 

According to the BBC website "Thomas Wang, executive director of Taiwan's Aviation Safety Council, said on Friday it was too early to draw firm conclusions about why the first engine had lost power but he told the BBC that the pilots had not followed normal procedure."

[azimuth]

Hopefully computers can take over more cockpit functions next time. The human brain cannot perform very well under fear and pressure. :-)

[Guest Sam Toon Ng]

anyone has experience flying with Cubana?

[Guest wozzit]

The human brain cannot perform very well under fear and pressure. :-)

 

 

But isnt that what pilots of technologically highly sophisticated aircraft r repeatedly trained to do - perform not merely well but outstandingly well under fear n pressure? A pilot has to react instantaneously, calmly n effectively under the most extreme circumstances.

 

Think of the BA Beijing to London flight in 2008 which crashed on landing. As the 777 was coming in to land at Heathrow the pilots suddenly found they had no thrust in the engines. A previously unrecognised problem of ice crystals forming had blocked fuel from reaching the 777s engines. The plane was only 220 meters off the ground n still had to fly 3 kms to get to the runway but actions to increase engine thrust met with no response. That plane could have crashed into houses near the airport or on to cars on the motorway around it. Instinctively the pilots disconnected the autopilot, adjusted flap settings n took other measures to try n keep that plane from falling out of the sky. They made it but it crash landed on to a grass verge. The plane was a write off but not one passenger was killed n all evacuated the plane safely.

 

That surely is an example of the human brain performing superbly under fear n pressure. As the accident report made clear it was only the speedy action of the cockpit crew that avoided a disaster. Both pilots were regarded in the aviation industry as heroes! The same is surely true of the Qantas A380 pilots who in 2010 guided their A380 back to Changi after it became technically uncontrollable due to an engine explosion.

I do agree that there are exceptions. Like what you mentioned this is what sets them back from the rest and they became heroes. They perform exceeding well under stress. Unfortunately, I cannot agree that all pilots are equally trained as that. :-)

[Guest wozzit]

Taiwan's Civil Aeronautics Administration (CAA) has ordered retraining for all 71 TransAsia pilots flying its ATR fleet.

 

Shocking news today that 29 Transasia pilots have been suspended for failing or missing the retraining testing. That's 29 out of 71. So 41% of that airlines pilots may not have had all the required skills to fly the ATR aircraft which crashed. Wld u b happy putting ur life in the hands of pilots not adequately trained to actually fly the plane u r in?

 

It surely points out one absolute of flying as a passenger. It doesnt matter how fancy n luxurious the passenger experience becomes or how cheap the tickets r or how modern the fleet, the airline u fly must hv the best training programmes n facilities, the best safety-based culture, the best engineers n experienced pilots highly trained in all the skills required to handle all emergencies - barring a total hull explosion (as happened to the Malaysian aircraft over the Ukraine).

 

WIll you now think more carefully about which airline u fly?

THAI's standards hv slipped badly in recent years n the quality of inflight seating n service suffers in comparison to other regional airlines. That vdo seems to add to the mess. Nothing whatever about the aircraft n its facilities. Just drinks n food falling upwards as though the aircraft had hit an air pocket! Beautiful visuals that hv nothing to do with an airline experience dont sell seats! The Vietnam ad is far more informative.

I guess the problem is there is no rating available on airline safety standards for consumers (correct me if I am wrong) to compare unless we look at the number of crashes per airline.

 :-)

I think thats more or less correct, unfortunately. Even then, an airline with a good safety record in the past is not a cast iron guarantee of unrelated problems in the future.

 

Cathay Pacific with its excellent record is one example. In 2010, an A330 from Surabaya encountered engine problems during the flight. The pilots decided it was safe to fly on rather than turn back. All was fine till the aircraft was descending. 83 kms from Hong Kong airport both engines showed stall warnings n one cut out. The pilots cut the auto-pilot n flew the plane manually, first increasing power on the one remaining engine to full thrust. They managed to bring that plane in to land safely at a speed 176 kph higher than the recommended maximum and massively over the standard flaps n tyre speeds. Only one thrust reverser worked, 5 tyres exploded but no-one was killed. The pilots were later awarded the Polaris Award by the International Federation of Air Line Pilots' Associations for their heroism n airmanship.

 

N the problem with that jet? Contaminated fuel supplied by the contractors in Surabaya! Without the skill of those pilots, the aircraft would hv crashed. 

 

Im no longer a fan of the CX in flight service on regional routes but I hv absolute faith in its pilots, maintenance n training methods.

[Guest milehiboi]

I think safety as a consideration is probably overstated. Even with the spate of incidents lately, air travel remains overwhelmingly safe. I definitely consider comfort and value more than safety most of the time. Anyone here looking forward to SQ PE?

[Guest wozzit]

I agree air travel is far safer than travelling by almost any other form of transport. But even airlines will tell u that safety is their primary concern. Ever listen to what the captain says soon after u get on to a plane? "Ur safety is our primary concern." N thank goodness for that, coz it enables u to spend more time looking forward to SQ's PE, Although if the experience of other carriers is to go by, PE is no great shakes. Cathay Pacific has just announced it is going to reduce the number of PE seats on some of its flights coz it cannot sell them!!

I think the Vietnam video is an AVP.  While the Thai vid is a TVC.. based on both videos' running times. Perhaps, Thai Airways have another video focusing on their facilities or services.  

[Enelym1978]

To be honest, the Dreamliner is not that frost for long hauls. I'm talking economy class of course.

It's only bearable if it's the ANA configuration of 2-4-2 across but they are already switching to the more "classic" 3-3-3 which is a bit too crammed for me.

Tried NH, UA and QR. NH was the best. UA came second and QR was nothing to talk about....

[Guest milehiboi]

Haha. I love QR but I get your point. I think 3-3-3 is just ridiculous in this day and age.

[Enelym1978]

Haha. I love QR but I get your point. I think 3-3-3 is just ridiculous in this day and age.

It's not ridiculous for the airlines. More profitable. Some airlines are even adding one seat on the existing 777s.....

[Guest milehiboi]

Yea. EK has ten across. I know the reason why they're doing it. As a consumer we just have to take it on the chin

[Enelym1978]

I never realized that both EK and EY had 3-4-3 on their 777s..... yikes. Only QR (and SQ for instance) has 3-3-3. Fingers crossed.

[Guest Guest]

I never realized that both EK and EY had 3-4-3 on their 777s..... yikes. Only QR (and SQ for instance) has 3-3-3. Fingers crossed.

 

I believe AIR FRance, British Airways, EVA ( Taiwan ) , United, Delta, have 3-4-3 ten across seating for their B777 intercontinetal flights, too,

 

Malaysia Airlines also have 3-4-3 and Thai Airways (maybe ).

 

This airlines make Singapore Airlines look like a fool for stickingto 3-3-3 seating in this era, because their tickets are not that much cheaper than SQ bu they can fit in more passengers and make more money wit 3-4-3 seating fitting more paying customers into their planes, that is why Sq is losing money every year now ,and their Business class products looks dated and old compared to newly refreshed ETIHAd airways,

 

and some Japanese airlines and some China domestic airlines have 3-5-3 eleven across seating for their B777 and older B747 seatings, go figure it out.

 

You can check at seatguru.com and Airliners.net , these two provide seating info on airlines.

Asiana plane skids off runway at Hiroshima, Japan

 

 

Air safety authorities in Japan are investigating how a South Korean Asiana Airlines plane skidded off a runway on landing at Hiroshima airport.

The 74 passengers and seven crew members used emergency chutes to evacuate the Airbus 320 in the incident late on Tuesday.

Local media reported that at least 20 people had minor injuries.

Transport ministry officials said a plane wheel may have clipped a radio facility near the runway on landing.

The structure, known as the localiser, helps aircraft find the landing strip. A fragment was found on the plane's left wheel, Japan's national broadcaster NHK reported.

Images from the scene showed apparent damage to the 6m (18ft) tower, with mangled metal torn down.

An aviation safety official told AFP news agency that the left side of the plane's tail was damaged and the country's transport safety board was investigating.

Asiana Airlines apologised for the incident, and said it had set up a response team to cope with the aftermath.

"As to the determination of the cause of the accident, we will co-operate as closely as possible with the relevant authorities," it said.

Passengers told NHK that they heard an explosion after landing, and the cabin was soon filled with smoke and a burning smell. The plane also appeared to be sliding on the runway.

"There was smoke coming out and some of the oxygen masks fell down. Cabin attendants were in such a panic and I thought 'we are going to die'," one woman told Japanese networks on Tuesday night.

The plane was flying to Hiroshima from South Korea's Incheon airport, near Seoul.

The airport was closed for several hours.

In July 2013, Asiana Airlines Flight 214 from Incheon crashed on landing at San Francisco airport after its tail clipped a sea wall.

Three people died in the crash - including one Chinese teenager who was run over by a firefighting vehicle in the chaos.

And two years prior to that, two Asiana pilots were killed when their China-bound cargo flight crashed into the sea off South Korea's Jeju island.

 

 

 

[Guest wozzit]

Seems some Asiana pilots r just too keen to get their planes down on to the runway. Following the SFO crash youd hv thought the airline would hv spent more time training pilots to ensure  these sort of things dont happen!

 

Apparently the plane descended too quickly n struck the communications structure some distance from the runway. It then came down heavily on the grass lead up to the runway itself. Bloomberg's report states Hiroshima has an Instrument Landing System at the east end of the runway n aircraft r supposed to land fm the west. It speculates that the plane "possibly approached from the east, an entry against the wind that that isn’t supported by the ILS, according to Kyodo (News Agency)." (If that turns out to b true, one wonders why air traffic controllers permitted it.) Also seems the pilots flew the descent manually.

 

If all the above turns out to b fact, then pilot error seems once again most likely the cause.

Anyone have similar interest in aviation and plane spotting. Do share dicussion and opinions. 

[upshot]

Use to be a big fan and would read up everything on old and modern planes. then got into aero-modelling building planes out of balsa and flying them including Hirobo Helicopters but have seen slowed to a crawl though I am interested in maybe getting into drones since I am also heavily into photography and drone cam seem very interesting as prices are coming down and tech is improving.

 

I do go to airshows just to marvel at them close up or shoot them in the air when they do air show aerial demos. Nothing as exciting as flying machines all the way from Wright Brothers to Airbuses or Lockheeds..

 

My favorite is still the Black Bird with their sexy ramjet tech going up to mach 3.2. Holy shit...

 

For fighters especially Russian fighters are way cooler dog fighting jets... like their Flankers MiGs 30s series over the years.

[FizzleBuzz]

Black bird 3.2 mach?! What and where is that made from?!

That is the famous or infamous spy plane that is a legend heheh.... I remember in the 80s MPH I think offer this month think page 'magazine' where you buy 3 months and get a hardcover folder ring binder and you keep all each months articles on various planes from fighters to commercial planes, I use to keep that and in it so much was talked about the Lockheed SR-71 Blackbird

 

Specs:

Top speed: 3,540 km/h

Introduced: 1966

Retired: 1999

Range: 5,400 km

Wingspan: 17 m

Engine type: Pratt & Whitney J58

Unit cost: 33,000,000–33,000,000 USD (1966)

 

Goosebumps reading those specs again heheh... I am sure you know this one by now looking at the model number. It retired undefeated... not even when the Russian could fire any missile at it and could catch it heheh.. And till today since it was made, still the most sexy plane in the world. I still hope to see this in real life at the museum or carrier in the US. I spotted it on a carrier in the New York Habor far off as I have to work and with my boss, no way I could take time off to see it heheh...

 

 

[FizzleBuzz]

Oh ya... i saw that pic but didnt know the model. Paiseh. Haha

 

But im not really a fan of pratt & whitney. Their engine doesnt seems as much refined as like others, rolls royce or CFM.

For commercial planes... I think the A380 is awesome.. Give a chance I try to book this especially for long flight. And the Rolls Royce engine are something you have to watch one of the video to really appreciate how well made and how much of redundancy that has been put into them. I feel it is quieter and smoother.

Gotta agree on that. The trent 900(i think) is one of the if not, the most remarkable engine with massive thrust. Faa also rated it as super heavy and 747 not so super heavy.
