Easyjet tries a Nanotechnology Coating on its aircraft aimed at reducing drag and increasing fuel efficiency.

By simou simoop

EasyJet Coats Airplanes With Ultra Thin Paint To Reduce Fuel Consumption

A high-tech coating used on military aircraft could make commercial planes more aerodynamic and allow them to fly more efficiently through the air. Budget airline EasyJet has applied the coating, invented by TripleO, to eight of its aircraft and will compare their fuel consumption to the rest of the fleet over the course of the year. If successful, all 194 of EasyJet’s aircraft will be coated. Experts say the coating could cut fuel costs by 2 percent, which would save EasyJet £20 million each year.

The nano-technology has been used on U.S. military aircraft, but this is the first time a U.K. airline has applied it to commercial planes. The coating, which is 100 times thinner than a human hair, smooths out microscopic bumps and nicks on a plane’s surface, letting it glide more easily when in flight, ultimately cutting fuel consumption and cost. It adds only 4 oz. of weight to the aircraft, and reduces the buildup of debris on the aircraft’s surface, thus reducing drag.

To work, the coating must be applied in two stages. First an aircraft is washed in a special solution to purge the plane’s pores and give it a positive electric charge. Then the main coating is applied with a negative charge. The oppositely charged molecules are pulled into any spaces and magnetically held there. The coating contains durable acrylic elements that create a perfectly smooth surface by filling the pores with a special resin. The coating also prevents the penetration of any contaminants or debris.

The fuel savings will result in a lower carbon footprint and lower costs, which will be passed on to airline passengers through ticket prices. Last year, EasyJet’s fuel cost was nearly £750 million, and with rising fuel prices, that could jump to £1 billion this year.

WHY THIS MATTERS

Airplanes use massive amounts of fuel, so any reduction in fuel consumption will result in less CO2 emissions, thus helping to curb global warming. If EasyJet’s trial with TripleO’s nano-technology coating is successful, more commercial airlines could start using it, meaning more airlines would reduce CO2 emissions.

Earth’s magnetic pole shifts, screws up runway at Florida airport

By Saurabh Vats

Earth’s magnetic pole shifts, screws up runway at Florida airport




An airport in Tampa, Florida, has had to temporarily close its runways to keep up with Earth's magnetic north pole, which is drifting toward Russia at a rate of 40 miles per year.

Fox News reports that the international airport was forced to adjust the signs on its busiest runway Thursday because pilots depend on the magnetic fields to navigate. The runway will be closed until Jan. 13, and will re-open with new taxiway signs that indicate its new location on aviation charts, the Tampa Bay Tribune reports.

Paul Takemoto, a spokesman for the FAA, says the Earth's magnetic fields are constantly in flux -- but rarely so much so that runway signage needs to be changed. "You want to be absolutely precise in your compass heading," he told Fox. "To make sure the precision is there that we need, you have to make these changes."

[Rewind: Scary gaffe adds to week of airline mishaps]

"The Earth's poles are changing constantly, and when they change more than three degrees, that can affect runway numbering," FAA spokesperson Kathleen Bergen told Fox News. It's unclear whether any other airports will have to adjust their runways.

Earth's magnetic field, which still flummoxes those who study it, "is thought to be generated deep inside the planet," LiveScience writer Jeanna Bryner explains. "An inner core of solid iron is surrounded by an outer core of molten iron. They rotate at different rates, and the interaction between the regions creates what scientists call a 'hydromagnetic dynamo.' It's something like an electric motor, and it generates a magnetic field akin to a giant bar magnet."

 

 

Sometimes, the poles completely flip -- and presumably when that happens, many bigger changes are afoot than modest tweaks to airport signs. The last time the planet experienced a polarity flip was 780,000 years ago.

Qatar Airways pilot died during flight

By Saurabh Vats

The captain of a Qatar Airways Airbus A330-300, flight QR645 from Ninoy Aquino International Airport(MNL) in Manila, Philippines to Doha Airport (DOH) in Qatar died of a heart attack during the flight, onWednesday morning, October 13.

The copilot took command of the aircraft, diverting to Kuala Lumpur International Airport (KUL) inMalaysia, landing at 11:30 a.m. local time on Wednesday, October 13. Paramedics were unable to revive the man, who was described as an Indian national.

Another Qatar Airways flight crew flew the aircraft from Kuala Lumpur to Doha, the capital of theQatar, arriving 272 minutes late (4-1/2 hours), according to flight status tracking at FlightSmart.com

Qatar, which has an emirate-type government, is located in the Middle East, bordered by Saudi Arabia and separated by the Persian Gulf fromBahrain. It is rich in oil and natural gas. Al Jazeera, an international news network headquartered in Doha, was among the first media to report the incident.

Qatar Airways said in a statement that its priority"remains the comfort and safety of its passengers and staff". It did not confirm the cause of death, or if the flight was ever at risk.

While rare for a cockpit crew to become incapacitated aloft, according to the British Civil Aviation Authority (CAA), there were 32 incidents during 2009 when pilots were incapacitated during a flight. During 2008, such situations occurred 39 times, caused by food poisoning, nausea and fainting.

The last reported death by a flight crew while airborne happened on June 18, 2009 when a 60-year-old pilot aboard Continental Airlines (CO) flightFlight 61, a Boeing 777-200ER, from Brussels AIrport (BRU) to Newark Liberty International Airport(EWR) suffered a fatal heart attack at 10:30 a.m. EDT over the Atlantic. The first officer and a relief pilot took over control of the aircraft. None of the 247 passengers on board the plane were aware of the tragedy.

Many commercial aircraft and airports around the world have computerized heart paddle defibrillatorsavailable which can deliver a shock to help restore normal cardiac rhythm to persons suffering heart related incidents. It is not yet known whether such equipment was on board the Qatar Airways flight, or if it were deployed.

This journalist was on a Northwest Airlines flight in 2007 from LaGuardia Airport (LGA) to Minneapolis(MSP), which had to return to the gate because a flight crew member had become critically ill. Our sympathies go out to the family, friends, and colleagues of the deceased Qatar Airways captain.

 The Qatar Airways pilot who died on a flight was a 43-year-old Indian national who worked with the airline for five years, according to a Qatari daily.

Ajay Kukreja suffered a massive heart attack shortly after he took off from Manila’s Ninoy Aquino International Airport, and his co-pilot had to fly the plane (Flight No QR645), with around 260 passengers on board, to Kuala Lumpur International Airport (KLIA) for an emergency landing.

After the pilot complained of a chest pain, the co-pilot requested permission from the KLIA authorities to land and asked that a medical team be on hand. The passengers on board were not told about the pilot’s condition.

However, the pilot was declared dead after the flight landed at KLIA.

The entire crew of the plane was changed, and it continued on its journey leaving Kuala Lumpur at 1.15pm and landing in Doha at 3.37pm, more than four-and-a-half hours behind schedule.

Meanwhile Kukreja’s body was taken to Serdang Hospital in Kuala Lumpur for a post-mortem. Reports said he died of cardiac arrest. He reportedly suffered a heart attack roughly an hour after the flight had left Manila.

Sources close to his family in Doha said he had no past history of heart problems. However, he was asthmatic and always carried an inhaler. His body will be flown to Mumbai directly from Kuala Lumpur, and Qatar Airways is also making arrangements to bring his family over.

Kukreja was from Delhi and had married woman from Goa, but his parents live in Mumbai. He has been living in Doha and working with Qatar Airways for five years. His widow teaches in a nursery in Doha, and the couple's two children, a 13-year-old boy and a 10-year-old girl, are students.

The aircraft landed safely at Heathrow

A British Airways jumbo jet with 296 people on board had to make an emergency landing shortly after taking off from Heathrow airport.

The Boeing 747, destined for New York, was over London at 0920 BST when a light in the cockpit indicated that one of the doors was not completely closed.

Wimbledon residents reported a low-flying aircraft as the jet turned and headed back to Heathrow.

The flight, BA117, landed safely at the west London airport.

In total the plane was airborne for 11 minutes.

Passengers were being put on another flight thought to be departing at 1500 BST.

'Smoke under wing'

Hannah Evershed was on board. She said: "It wasn't fun. I fly a lot for work and I knew we were flying too low.

"The pilot alerted the cabin crew over the loudspeaker to answer his calls. It all happened quite quickly."

Ms Evershed added: "Other passengers were quite calm but I was nervous.

"I'm travelling with my fiance and he saw smoke under the wing.

"We're waiting for engineers and hopefully we'll be on another flight this afternoon."

A British Airways spokeswoman said a full investigation was taking place.

She added: "Obviously it takes a bit of time to find another aircraft but we are looking to do that as soon as possible."

A spokeswoman for Heathrow operator BAA said the problem had been traced to a faulty light.

Kingfisher flight (IT 3214) goes 'missing' for 30 minutes

By Aman Kumar
Kingfisher flight goes 'missing' for 30 minutes


A Kingfisher flight created panic after it lost radio contact with the Air Traffic Control (ATC) for around 30 minutes. Flight IT 3214 from Delhi to Bangalore could not be contacted for 30 minutes on Wednesday afternoon. The flight that lost contact during transition from the Delhi to Nagpur Air Traffic Control had over 150 passengers onboard. 

The Directorate General of Civil Aviation (DGCA) has initiated a probe, even as sources say that the cockpit voice recorder and the black box will provide clues. 

Director General Naseem Zaidi said the air safety director will probe whether the incident involving the Delhi-Bangalore flight took place due to lapses in following standard operating procedures by pilots and ATC or due to a technical snag. 

According to sources, Kingfisher flight (IT 3214) took off from Delhi at 2.05 pm. “The flight was assigned 33,000 feet and was, initially, in contact with the Delhi ATC, which asked it to report to Nagpur area control as it flew southwards. Not only did the pilots failed to contact the controllers, but they also didn’t respond to calls on regular and emergency VHF frequencies by the ATC and other flights in the vicinity to establish contact with them,” sources said. 

However, the plane, which was being constantly tracked on the radar, maintained the assigned flight level, they added. 

When a flight switches over to another ATC unit, pilots are expected to inform the controllers about its flight level, call sign and a four digit squawk code assigned to them. 

“This information helps the controllers to verify whether or not it is the same aircraft that they are tracking on radar. However, IT 3214 failed to do so,’’ the source said. 

“After about 30 minutes the flight established contact with Nagpur controllers and sought a deviation from its route,’’ an official said. 

Pilots and air traffic controllers familiar with Nagpur said there are certain blind spots where VHF and radar coverage is poor. 

Some even suggested that Kingfisher pilots were monitoring wrong frequencies and were therefore unable to listen to calls made by Nagpur ATC. 

Kingfisher spokesperson said, “Preliminary indications are that the pilots reported bad weather and heavy static when they transitioned from Delhi area control to Nagpur area control. 

As soon as they were able to contact Nagpur, they sought and received a deviation to avoid the spot of weather. Further investigations are on.’’

Bomb scare forces Pakistan-bound plane to land in Sweden


STOCKHOLM (AFP) – A Pakistani airliner made an emergency landing in Stockholm over a bomb threat Saturday, but hours later Swedish authorities released a detained suspect after no explosives were found.

The Pakistan International Airlines (PIA) Boeing 777 was on its way from Toronto to Karachi when it diverted to land at Arlanda airport around 0730 GMT, following an anonymous phone call warning a man on board may have explosives, police said.

After questioning the suspect, a Canadian citizen of Pakistani origin, and thoroughly searching the plane but uncovering no explosives, the man was released without charge and allowed to leave Sweden.

"The prosecutor on duty decided not to keep the man suspected of having explosives on the airplane in detention," Swedish prosecutors said in a statement.

"The suspicions against this man are not sufficiently solid to keep him in detention and so he is free to leave Sweden," the statement said, adding that "no further information can be given for moment."

Canadian authorities meanwhile said they were opening an investigation into the alert, which was triggered by an anonymous phone call.

After being alerted to the possible presence of a bomber on board, the crew of PIA flight PK-782 decided to make the emergency landing in Sweden.

"A woman contacted the Canadian police and said there was a man on board that could have explosives on him. We do not know for the moment who this woman is," Janne Hedlund of the Stockholm police told the TTnews agency.

Hedlund said the call came from a telephone box.

Canadian police say they are looking into whether the bomb alert they received was a "terrorist hoax", a RoyalCanadian Mounted Police (RCMP) spokesman in Toronto, Marc Laporte, told AFP.

The RCMP declined to the name of the passenger detained in the incident, or give any information on the phone caller or where the call was made.

The plane was carrying 261 passengers, including the suspect, and 18 crew members, according to PIA. It was taken to an isolated area of the airport where police used sniffer dogs to search it and the baggage for explosives.

"The searches were finished in the afternoon, we didn't find anything suspect or dangerous," said Stockholm police spokesman Kjell Lindgren.

The passengers were led inside the terminal and received food and assistance, an airport spokesman said, adding that psychological counseling was on hand.

Police interviewed some of the passengers in addition to questioning the suspect, who was held at the airport's police station.

Swedish police said the man was a Canadian citizen aged around 30, while a PIA spokesman said he was of Pakistani origin.

After receiving the all clear from Swedish authorities, the plane took off around 1500 GMT for Manchester in northwest England.

The airline decided to send the plane on to Manchester because the crew was too tired to complete the flight to Pakistan, Arlanda airport spokesman Jan Lindqvist said.

QANTAS jet's mid-air drama

A Qantas jet bound for Sydney was forced to turn back to San Francisco after an engine problem punched a hole in the metal shell around it.

Flight 74, carrying 212 passengers and a crew of 18, left San Francisco for Sydney at 11.05pm on Monday local time (4.05pm AEST on Tuesday) and returned at 12.45am (5.45pm AEST), San Francisco airport duty manager Carol Spear said.

About 15 to 20 minutes into the flight, the crew noticed "excessive vibration" in engine No. 4 of the Boeing 747-400, Qantas Airways spokesman Simon Rushton said in Sydney.

"After some initial troubleshooting, they made the appropriate decision to shut the engine down," Mr Rushton said.

"They also made the appropriate decision to seek priority clearance to return to San Francisco."

The pilot dumped fuel over the Pacific as a precaution, he said.

There were no injuries during the landing, Mr Rushton said, and the plane was able to pull up to the aerobridge at the terminal so passengers could get off the plane.

Engine failure a very rare event: Qantas

Mr Rushton said engine failures were "very rare events" and there was no fire. He could not say whether similar incidents had occurred to other Qantas planes.

"Engineers have determined the engine does need replacement, and they are checking to see what caused the problem," he said.

"We are ... dispatching a replacement engine early this afternoon to San Francisco along with a team of Qantas engineers who will also take the replacement and begin the investigations into what has happened."

But an engine surge can often cause what appear to be flames. The flames created a large hole in the engine cowling, the metal shell around the engine.

An aviation expert, John Nance, told the San Francisco Chronicle the incident was an "uncontained engine failure" that was "an extremely rare event".

He said Boeing 747s were designed to "lose three of four engines and still be able to get back".

Crew looked alarmed: passenger

Passenger Nolan Goldstein told local television station KTVU-TV she "heard a thud, a bump and the plane veered off to the left".

"It was very uncertain for a period of time until the captain announced that we had an engine that blew up. ... It was a real uncomfortable vibration at first and then the plane began to shake a bit."

"It wasn't turbulence," passenger Neil Dufty told KTVU. "It seemed that there was some pretty serious damage. People on the right-hand side of the plane seemed very shocked. Apparently, there were flames coming out of the engine.

Another passenger, Elizabeth Thomas said she heard a "very strange noise" that was "hard to describe".

"I don't travel that much but I knew it was very wrong," she told KTVU. "The staff looked a little alarmed and began to move very quickly."

Mr Dufty said the pilot "assured everybody that the plane was still relatively safe".

"There was serious damage in one of the engines. We jettisoned some fuel and turned around. The captain made a very good landing. We all cheered."

Mr Rushton said passengers were given hotel accommodation and meals.

"We are transferring them to Los Angeles to pick up Qantas flights to Los Angeles tonight to Australia."

The Federal Aviation Administration (FAA) in the US said Qantas will prepare a report into the incident for the FAA and the National Transportation Safety Board.

"Whatever Qantas does is going to have to meet with our approval too," an FAA spokesman said.

"The bottom line is we want to make sure and know that that aircraft is airworthy when they are saying they want to put it back on line."
