Have The Right Emergency Plan For Helicopter Safety

Flying a helicopter is a challenge for most pilots simply because helicopters struggle with opposing forces in order to keep itself airborne. As such, there is a need to ensure the safety of helicopter flights using proper energy management. Energy management can help the helicopter fly safely in case of engine failure and prevent it from rising to unusual altitudes.

All aircraft safety relies on energy management. An airplane, for example, relies on potential energy to maintain altitude and kinetic energy to maintain forward speed. A pilot needs to play between these two kinds of energies in order to successfully maneuver the plane and bring it gently to the ground if they need to land it or if they experience engine failure.

With a helicopter, a pilot has to manage three types of energy: potential energy to maintain altitude, kinetic energy to maintain forward speed and angular momentum to maintain blade speed. Unlike airplanes in mid-air, helicopters can’t fly without an engine. If the rotor blades slow down, you simply can’t convert potential energy into kinetic energy and make the rotor blades spin.

Say for example the helicopter is losing altitude because the engine stops. There is no need to waste more energy on trying to kick start the rotor blades. You’ll have to lower the helicopter’s collective pitch to flatten the rotor. They will now be spun by the wind that passes through them as the helicopter falls. You can then use the remaining energy on adjusting the cyclic to maintain forward speed, all the while aiming for your landing zone.

As the ground nears, you’ll have to pull back the cyclic in order to reduce forward speed. This helps flare the helicopter. Seconds before it touches the ground (about 6′ feet from the ground), you can stop the flare and keep the helicopter parallel to your landing area. Once you raise the collective, you simply use the potential energy on the blades against gravity and allow the helicopter to land safely.

Maintaining the descent rate means using more power. To settle, the helicopter must be flown forward, away from the vertical descending column of its rotor downwash. A full collective will only deplete the helicopter’s energy reserves, which are better off used to produce a forward motion.

If you have a high-performance helicopter, energy management may not be as much of a concern. These helicopters allow sufficient power reserves that prevent vertical descent, provided of course, that your helicopter flies without an extra load.

Russia celebrates Victory Day

Monday, May 10, 2010

Russia yesterday celebrated Victory Day, to commemorate the 65th anniversary since Nazi Germany surrendered.

In a first for the annual celebrations, soldiers from other countries joined in the parade, including those from former Soviet allies in the war: the United States, the United Kingdom, France, and Poland.

Leaders from other countries were present at the event, including Angela Merkel, the German chancellor, the Polish acting president Bronislaw Komorowski, Israel’s Shimon Peres, and China’s president, Hu Jintao.

Media reports describe the events as being among the most elaborate since the Soviet Union fell apart two decades ago. Anti-aircraft rockets, mobile howitzers, and missiles rolled through Red Square, and 150 airplanes and helicopters performed a flyover shortly thereafter.

Russian president Dmitriy Medvedev speaking during the celebrations at Red Square, appealed for international solidarity: “Only together can we counter present-day threats. Only as good neighbours can we resolve problems of global security in order that the ideals of justice and good triumph in all of the world and that the lives of future generations will be free and happy.”

Chrysler files for bankruptcy, Fiat Group SpA to run company

Friday, May 1, 2009

The American auto company Chrysler filed for bankruptcy Thursday, however a deal with European auto maker Fiat went through. The emerging Chrysler will be owned 55 percent by the United Auto Workers, eight percent by the United States Government, two percent by the Canadian Government and Fiat would begin with a 20 percent share.

Chrysler Chief Executive Robert Nardelli will step down when the bankruptcy proceedings are finalized.

Initially, the Italian company, Fiat, will appoint three members on the emerging Chrysler’s new board, and the United States government will appoint six. Fiat can assume the majority of the ownership upon repayment of American loans.

Chrysler administrators expect that the bankruptcy should take a couple of months.

“We expect this to be a very short, 30-to-60-day bankruptcy process, during which the company will function normally,” a top administration official said, “People will be able to buy cars, they will have their warranties honored, and everything should go on normally.”

The bankruptcy filing indicated that Chrysler was in debt to 20 creditors to a tune of more than $10 million each.

Meanwhile, the deal with Fiat did go through, and Chrysler should have cars designed by Fiat out on the market by 2011.

“It’s a partnership that will give Chrysler a chance not only to survive, but to thrive in a global auto industry,” said American president Obama, “Fiat has demonstrated that it can build the clean, fuel-efficient cars that are the future of the industry.”

However, automotive analyst Erich Merkle has hesitations.

“History would show that alliances really don’t work that well,” Merkle said, “even though, no matter how good they may look on paper.”

The restructuring has been managed by Steve Rattner, a former investment banker, and the U.S. Government auto task force.

Obama has set three ultimatums before Fiat. Fiat should produce a 40 mile per gallon vehicle while managing the new Chrysler, transfer fuel efficient Fiat technology to Chrysler factories in the United States, and produce cars in Chrysler factories and distribute them in Europe.

Banned film ‘The Profit’ appears on Web

Sunday, March 23, 2008

Copies of The Profit, a 2001 film blocked from distribution in the United States due to a court injunction won by the Church of Scientology, appeared on the Internet Friday on peer-to-peer file-sharing websites and on the video sharing site YouTube.

Directed by former film executive Peter N. Alexander, the movie has been characterized by critics as a parody of Scientology and of its founder L. Ron Hubbard. Alexander was a Scientologist for twenty years, and left the organization in 1997. The film was funded by Bob Minton, a former critic of Scientology who later signed an agreement with the Church of Scientology and has attempted to stop distribution of the film. Alexander has stated that the movie is based on his research into cults, and when asked by the St. Petersburg Times about parallels to Scientology and L. Ron Hubbard said: “I’ll let you draw that conclusion … I say it’s entirely fictional.”

The film was released in August 2001, and was shown at a movie theatre in Clearwater, Florida and at a premiere at the Cannes Film Festival in France. A Scientology spokesman gave a statement at the time saying “the movie is fiction and has nothing to do with Scientology”. The Church of Scientology later took legal action in an attempt to stop further distribution of the film. The Church of Scientology claimed that the film was intended to influence the jury pool in the wrongful death case of Scientologist Lisa McPherson, who died under Scientology care in Clearwater, Florida.

In April 2002, a Pinellas County, Florida judge issued a court order enjoining The Profit from worldwide distribution for an indefinite period. According to the original court injunction received by Wikinews, the movie was originally banned because the court found that it could be seen as a parody of Scientology. In his April 20, 2002 ruling on the injunction, Judge Robert E. Beach of the Sixth Judicial Circuit Court in Pinellas County, Florida wrote: “…an average person viewing the film entitled The Profit could perceive that it is a parody of the Church of Scientology”.

“To the extent that any person considered as a potential juror in evaluating any issues involving the Church of Scientology, the process of voir dire provides a fair and complete remedy to eliminate any potential juror that may possibly have been influenced to be less than fair and impartial,” added Beach.

Luke Lirot, the attorney for the film’s production company, announced on the film’s website on April 7, 2007 that “We have absolutely no exposure for any repercussions from the court order,” but that the film was still blocked from distribution due to an ongoing legal battle. Lirot wrote: “all that’s stopping the release of the movie is the legal battle with the partner who was compromised by Scientology (Robert Minton) and is currently using his power as partner to stop the release of the film.”

In an October 2007 article, The Times described the film as “banned in the US because of a lawsuit taken out against it by The Church of Scientology,” and Russ Kick’s The Disinformation Book of Lists included the film in his “List of 16 Movies Banned in the U.S.”. An 8-minute teaser segment from The Profit appeared on the film’s website and on the video sharing site YouTube in February 2008, and an attorney representing Bob Minton sent a letter to Luke Lirot requesting that the film clip be taken down. In a response letter, Lirot wrote that “Rather than damage any asset of the LLC, the short clip merely keeps the film in the public eye, and in a positive way.”

On Friday, copies of the film began to circulate on peer-to-peer file-sharing websites and on YouTube. A link related to the film’s appearance on the Internet on the community-based link aggregator website Digg.com had 3,638 “Diggs” – and hit the front page of the site’s Entertainment section on Saturday.

I had nothing to do with this release at all. But I’m happy it’s out there.

On Saturday, Scientology critic and Emmy award-winning journalist Mark Bunker put a streaming version of the film on his website, www.xenutv.com, and encouraged others to watch and discuss the film on a real-time chat channel. In a video posting to YouTube Saturday, Bunker said “I did not do it. I had nothing to do with it … I had nothing to do with this release at all. But I’m happy it’s out there … people are finally having a chance to see it. A lot of people have been curious over the years and there’s been a lot of interest in seeing the film, so finally you can.”

We have all wanted to see this movie that scientology kept hidden away from us. We have all wondered just how damning could this story be that we were banned from watching it.

On the newsgroup alt.religion.scientology, a poster by the username “Alexia Death” commented on the film’s appearance on the Internet in the context of censorship: “It is out! And so it is a WIN if many people review it even if they say it SUCKS! … Being bad is no cause to allow censorship … And being censored is no cause to assume its good”. A post to the blog Blogsreel commented: “We have all wanted to see this movie that scientology kept hidden away from us. We have all wondered just how damning could this story be that we were banned from watching it.”

In a post on Sunday to the message board attached to the official website for the film, attorney Luke Lirot asked that individuals stop distributing copies of The Profit over the Internet. Lirot wrote: “It has been brought to my attention that several unauthorized transmissions and downloads of this protected work have taken place over the last 72 hours. Such actions are copyright violations and are unlawful. I request that any further distribution and/or dissemination of this important work cease immediately and any copies of the work that have been downloaded please be deleted.” In his statement, Lirot recognized the rights of individuals under the First Amendment to the United States Constitution, but also said that unauthorized distribution of the film “will only serve to harm the goal of vast distribution”.

Blog postings have attributed the film’s appearance on the Internet as part of the anti-Scientology movement Project Chanology organized by the Internet-based group Anonymous, but this has not been confirmed. Wikinews previously reported on international protests against Scientology which took place as part of Project Chanology on February 10 and March 15. A third international protest by Anonymous is scheduled for April 12. Titled “Operation Reconnect”, the third international protest will focus on highlighting Scientology’s practice of disconnection.

New legal British tender revealed

Wednesday, April 2, 2008

For the first time in 40 years, the Royal Mint has chosen a new set of designs for the reverse of the coins, first introduced in the Coin Design Competition 2005. The designer, Matthew Dent of Bangor, North Wales, was paid £35,000 (GBP) for his designs, which depict the Shield of the Royal Arms spread over the six denominations below £1, with the entire shield embossed on the £1 coin.

The new coins are expected to come into circulation this summer – and Mr Dent envisions a success: “I can imagine people playing with them, having them on a tabletop and enjoying them. I felt it was important to have a theme running through from one to another.” he said, referring to the puzzle-like nature of the new design, which requires the coins to be arranged in a particular way to see the Shield of the Royal Arms.

The chief executive of the Royal Mint, Andrew Stafford, has said that the obverse of the coins will still depict the portrait of the Queen, like it has since 1998. The old coins will remain legal tender until they slip out of circulation.

‘Unfounded and unsubstantiated’: London policemen cleared of beating Muslim

Monday, June 6, 2011

A jury last week cleared four officers from London’s Metropolitan Police of assaulting a Muslim arrested on suspicion of al-Qaeda involvement. After trial their lawyer described the charge as “unfounded and unsubstantiated” – but in 2009 the police said Babar Ahmed, 34, had suffered “a serious, gratuitous and prolonged” assault.

Ahmed has been previously paid £60,000 in a civil case, which the jury was unaware of. After one hour of deliberations, they acquited Pc Roderick James-Bowen, 40; Pc Mark Jones, 43; Pc Nigel Cowley, 34; and Detective Constable John Donohue, 37, of assault occasioning actual bodily harm.

The four officers claimed at trial that Ahmed’s wounds were either self-inflicted or caused during legal restraint during his December 2003 capture. They said he had fought hard against arrest. The prosecutor contended the four officers, from the specialist Territorial Support Group, “punched and [beat Ahmed] on the floor,” calling him a “fucking bastard” and a “fucking cunt.”

“On the floor the assault continued as his wife called out for the police to stop,” Jonathan Laidlaw, prosecuting, told the jury. This was followed, he claimed, by a visit to Ahmed’s prayer room, where he was positioned as if praying and asked “Where is your god now? Pray to him.”

The prosecution alleged further abuse against Ahmed in a police van en route to the police station, with Ahmed saying at Charing Cross police station he was attacked again in an area not covered by CCTV surveillance. He was left, in the words of Laidlaw, with “areas of bruising, reddening and grazes to [his] head and neck, bruising to the chest, areas of bruising to [his] back, extensive bruising and grazing of the arms. In effect, there were injuries all over the victim’s body.”

The defence noted that MI5 bugged Ahmed’s house and a recording of the arrest failed to show elements of the alleged attack. James-Bowen told the court of a “ferocious” fight with Ahmed, who used “significant force.” Jones told the jury his superiors had informed him Ahmed had been trained in both armed and unarmed fighting.

Less than a year earlier, a similar operation in Manchester resulted in an officer stabbed to death by a suspect now serving life in prison. The four officers dealing with Ahmed had been warned their suspect posed a similar threat.

Speaking outside court, their solicitor, Colin Reynolds said the men were now able to “[get] on with their professional lives” following the dismissal by the jury of “unfounded and unsubstantiated allegations.” Local media had been barred during trial from reporting that, between the two of them, Jones and James-Bowen had been accused of a total 40 assaults from 1993 to 2007, all of which have been rejected. Jones was previously tried for assaulting two teens in the back of a police van and yelling racist abuse at them, but was cleared.

Fiona Murphy, who represents Ahmed, was critical of the Independent Police Complaints Commission. “We now call upon the IPCC to put its abject failures in relation to this case to one side and to give proper consideration to the misconduct aspects.” Ahmed released a statement, saying, “Today’s verdict means that no police officer has been held to account for this abuse. Therefore I urge the Metropolitan police to bring disciplinary proceedings against all officers who were personally involved in the assault – and those who turned a blind eye.” His father read it out at a post-trial press conference.

Ahmed was never charged, but was re-arrested in 2004 and has spent the last seven years in custody facing extradition to the US. The US seeks to try him for fundraising for militancy amid claims he is a member of al-Qaeda; though initially a ruling in favour of extradition was reached an appeal is pending.

Judge Geoffrey Rivlin QC, who oversaw the trial, expressed support for Ahmed’s position detained without trial: “I express the hope that his ordeal as a man in detention in this country for a number of years without trial is brought to an end as soon as possible, either by his extradition or by his release. It is no concern of this court as to which, but it is a matter of concern and I would have thought should be a matter of concern to the public at large, quite apart from Mr Ahmed, that here is a man who has been in custody for literally years without knowing what his fate is to be.”

Reflections, Lichtenstein, two new exhibitions at Edinburgh’s Modern One

Saturday, March 14, 2015

This weekend saw the opening of two new exhibitions at Edinburgh’s National Gallery of Modern Art. Wikinews attended Thursday’s press preview for the event where a full contingent of the capital’s press turned out to see the striking collection of paintings, photographs, and other works. Presented below are a selection of images captured at the preview.

REFLECTIONS: A Series of Changing Displays of Contemporary Art, billed as a showcase of a “diverse range of internationally-renowned contemporary and modern artists” is to display major works from the Gallery’s permanent collection, alongside important loans. Alongside this broad range of works, a three-room display of pieces on-loan from the Roy Lichtenstein Foundation — with a dramatic painted steel relief, ‘borrowed’ from the Tate in London — runs from March 14 through to January 10 next year.

Admission to both exhibitions is free; being located in Dean, to the north-west of Edinburgh’s city centre, a free Gallery bus service is available.

Egyptian treasures found in ancient tomb

Friday, March 13, 2009

A team of archaeologists excavating an Ancient Egyptian tomb have discovered golden jewelry in a recently-discovered lower chamber at the Valley of the Kings burial site in Luxor, Egypt.

Two golden rings and five golden earrings were found in the tomb of Djehuty, an 18th-dynasty official of Queen Hatshepsut, and were probably the property of Djehuty or his family.

The discovery was announced by Farouk Hosni, Egypt’s current Minister of Culture.

Djehuty was overseer of the treasury and overseer of works for the Queen. Hatshepsut reigned approximately 1479–1458 BCE. Djehuty was responsible for managing the huge amounts of precious goods brought in from Egypt’s military expedition to Punt in the Horn of Africa and the vast building projects of Hatshepsut which have made the female pharaoh one of the most-remembered of any from ancient Egypt.

Djehuty died after Hatshepsut did, sometime during the reign of Thutmosis III. Both Hatshepsut’s and Thutmosis’s names are recorded on the tomb. In a fashion typical of ancient Egyptian rivalries, Hatshepsut’s name was partly obscured on the monument over the tomb sometime after the queen’s death.

The team, led by José Manuel Galán of the National Research Center (Consejo Superior de Investigaciones Científicas, CSIC), in Madrid, Spain, had been excavating the tomb, designated TT11 and located in the necropolis of Dra’ Abu el-Naga’, since 2002. While much of Djehuty’s funerary equipment was lost to fire in antiquity, the lower chamber of his tomb was concealed at the end of a three-meter shaft and discovered at the end of 2008.

A superficial description of the tomb itself was recorded almost two hundred years ago by 19th-century French Egyptologist Jean-François Champollion, rubble blocking the entrance hindered excavation until the 21st century. In that time, emphasis in Egyptology has changed from the cataloging of treasures to the investigation of ancient culture, life and religion.

Since excavation began, Djehuty’s tomb has yielded a number of surprises. It was discovered that the tomb was re-used repeatedly up to and during the Greco-Roman period. There is an unusual face-on depiction of pharaoh Thutmosis III hunting ducks, and the mummy of a young, bejewelled, as-yet unidentified woman.

In 2007, 44 preserved bunches of flowers thought to be from Djehuty’s funeral were found in the site. In their 8th season of excavation, which ended on February 22, 2009, the team also found considerable evidence that below Djehuty’s tomb is a network of burial sites from the 11th dynasty, four thousand years old.

The lower chamber also displays passages from the Egyptian funerary text the Book of the Dead on its walls and a colorful mural of the goddess Nut, an embodiment of the heavens, on the ceiling. The names of Djehuty and his parents were also intact in the second chamber; the names were defaced in the previously-known first chamber of the tomb, which had also been looted.

According to a press release from Dr. Zahi Hawass, Secretary General of Egypt’s Supreme Council of Antiquities, Djehuty’s tomb is only the fifth known decorated burial chamber of the 18th dynasty. An additional unusual feature of the tomb is that its upper chamber is decorated in relief, rather than simply paint. When the excavation is completed, Dr Galán’s team plans to open the site to the public as the carved stoneworks will not be destroyed by tourists’ activities as paint would.

The identification of Djehuty is a complicated one, as a number of officials of the 18th dynasty bore the name, including a general and several governors. The name itself is an alternate transliteration of the name of the Egyptian god usually written in English as Thoth.

Doctor diagnoses Mexican artist Frida Kahlo’s infertility

Monday, April 23, 2012

File:Frida Kahlo by Artist René Romero Schuler.jpg

According to a new diagnosis by a surgical pathologist, Frida Kahlo most likely suffered uterine damage during a streetcar accident as a teenager and this led to a rare condition known as Asherman’s syndrome, and that would explain the Mexican artist’s infertility.

Dr. Fernando Antelo, from the Harbor–UCLA Medical Center, said, “Her survival defied the grim prognostication by her physicians; however, complications from this physical trauma would emerge in her adulthood.” He presented his diagnosis yesterday at the annual meeting of the American Association of Anatomists in San Diego.

Asherman’s syndrome is normally caused by a trauma to the uterus that results in internal scar tissue. For example, it can occur after multiple procedures to clear the uterus after a miscarriage or abortion, which is known as a “D & C” procedure. Antelo said Kahlo tried to have children many times and her miscarriages, as well as three therapeutic abortions, could have further aggravated the scarring.

At present the condition could be diagnosed and treated after advancements in medical imaging and hysteroscopy, but in Kahlo’s time, Dr. Antelo said, the technology had not advanced far enough to diagnose and treat her. Asherman’s syndrome has been known since 1894 when it was first reported. Kahlo died at age 47 in 1954.

“She kept attempting to have children with a uterus that wasn’t in any condition to do that,” Antelo said.

Antelo, who has been working on connections between art and medicine, says that Kahlo brought her infertility to the canvas and this can be seen in her many paintings of reproductive organs or in her depiction of her own bleeding body in the 1932 painting Henry Ford Hospital. In that image, Kahlo is shown lying on a hospital bed with multiple umbilical cords extending from her body and each one holds an object or body part, except one holding a baby.

Building partially collapses in New York City’s Upper West Side

Thursday, July 14, 2005

A building being prepared for demolition collapsed this morning in New York‘s Upper West Side around 9 a.m. EDT. Five people are known to be injured from the accident, as well as one rescue worker who was injured in the aftermath. None of the injuries were life-threatening.

The building was a supermarket, which was being taken down to make room for a high-rise building, something that residents took issue with. The roof, front wall, and scaffolding all fell to the ground, as stated by Fire Commissioner Nicholas Scoppetta.

Soon after the incident at least 100 police and fire department personnel combed the wreckage for more victims, using search and rescue dogs to find people by scent. They quickly accounted for the twenty-five construction workers who were working on the supermarket. Most of the victims’ injuries were broken bones, including one person who broke all four extremities.

Subway lines 1, 2, and 3 have been closed or redirected in response, along with the M104 bus.
