RIO – Em entrevista coletiva em Recife na manhã desta segunda-feira o tenente-coronel Henry Munhoz, da assessoria de imprensa da Força Aérea Brasileira (FAB) e do Comando da Aeronáutica, afirmou que as ações de busca e resgate continuam, ininterruptas, e concentradas nos pontos onde foram localizados os corpos de vítimas do acidente com o Airbus A-330 da Air France.

Paralelamente a essas ações, a aeronave R-99 permanece realizando varreduras eletrônicas no intuito de identificar outros focos de destroços.

– As condições meteorológicas não atrapalham as operações de busca e resgate neste momento, porém, existem áreas de instabilidade próximas ao Arquipélago de Fernando de Noronha – informou Henry Munhoz.

Atualmente a Operação conta com 14 aeronaves, sendo 12 da Força Aérea Brasileira e duas da França. O Navio-Patrulha Guaíba está substituindo o Navio-Patrulha Grajaú, que retorna para Natal (RN).

– Os meios navais continuam compostos por cinco navios da Marinha do Brasil e uma Fragata da Marinha da França.

O sindicato de pilotos da Air France afirmou nesta segunda-feira ter pedido a seus associados que não voem enquanto a companhia aérea não mudar os sensores de velocidade dos Airbus A330 e A340, dispositivos considerados uma das possíveis causas do acidente com o voo 447, no último dia 31.

“A companhia disse que vai mudar os sensores nas próximas semanas. Nós queremos proteger nossas tripulações e nossos passageiros, por isso não podemos esperar esse prazo”, disse o líder sindical Christiphe Presentier na emissora “France Info”.

Por isso, o sindicato assegurou que pediu a seus membros “que não voem se o aparelho não tiver pelo menos dois dos três sensores modificados”.

Presentier afirmou que se trata de “uma medida de precaução” enquanto se investiga a possibilidade de uma falha nesses sensores ter provocado o acidente do Airbus-A330, que voava do Rio para Paris.

O líder sindical lembrou que o Escritório de Investigação e Análise (BEA, na sigla em francês), responsável pelas averiguações sobre a tragédia, apontou os sensores como uma das possíveis causas do acidente, embora ainda não tenha dado uma explicação conclusiva.

Presentier indicou que no ano passado foram registrados outros problemas na Air France e em outras companhias relacionados com os sensores de velocidade.

Segundo o BEA, esses sensores enviaram informações contraditórias sobre a velocidade do voo AF447 que caiu no Atlântico.

A incoerência desses dados fez com que alguns sistemas eletrônicos do avião deixassem de funcionar, como o piloto automático, segundo o BEA.

No entanto, os responsáveis pela investigação afirmaram que é cedo demais para se saber as causas do acidente.

A Air France, por sua vez, assegurou que acelerou o programa de substituição dos sensores, iniciado em 27 de abril passado, após os incidentes registrados em vários de seus aparelhos.

A companhia aérea francesa mudou esses sensores em sua frota A320, a primeira em que foi registrado algum tipo de problema, e não iniciou a substituição nos A330 e A340 até que a Airbus propusesse um modelo compatível.

Sir Richard Branson: These dramatic pictures bring home the horror of what happened last week. It’s very sad and I hope the investigators reach conclusions as quickly as possible.

Recovery personnel have located the vertical fin of the Air France Airbus A330 which crashed in the South Atlantic on 1 June.

The Brazilian defence ministry says it has discovered “dozens of structural components” from the aircraft.

Search teams have also retrieved a total of 16 victims, it adds. There were 228 occupants on the aircraft when it disappeared en route to Paris from Rio de Janeiro.

Round-the-world solar aircraft prototype to be unveiled this month

Click here for more news / Clique aqui para mais notícias

Sir Richard Branson: This has the potential to be a major breakthrough in renewable energy usage in aviation. Solar power is free, yet it’s untapped. Let’s have a vision that half our aircraft fly on solar power by 2030.

Researchers are preparing to unveil the prototype of a solar-powered aircraft which is intended eventually to conduct a transatlantic and round-the-world flight.

The Solar Impulse aircraft, under development for several years, will be shown off at Switzerland’s Dubendorff Airfield on 26 June.

Tests of the Solar Impulse, construction of which began in 2007, are set to take place later this year with a view to performing a 36-hour zero-fuel flight in 2010.

It has a wing span of 61m (200ft) and four engines producing 30kW of power, enabling it to fly at about 38kt (70km/h).

The aircraft’s single-pilot cockpit is unpressurised, limiting its altitude to 8,500m (27,900ft), but the prototype is intended purely as a validation and experimentation platform.

“Current solar aircraft are not designed to store energy and therefore have to land in cases of insufficient sunlight,” says the development team.

“To demonstrate the formidable potential of renewable energies, Solar Impulse intends to place the bar much higher and have a piloted aircraft fly night and day without fuel.”

This can only be achieved, says the team, by a “drastic reduction” in energy consumption.

Solar Impulse was launched by pilot Bertrand Piccard and the project’s co-founder Andre Borschberg. Piccard was one of the pilots of the Breitling Orbiter 3 expedition which performed the first non-stop circumnavigation of the Earth by balloon.

The solar-powered aircraft programme has been backed by primary sponsors Deutsche Bank, Omega and Solvay.

If the trials are successful a second aircraft will be built to attempt several consecutive 24-hour cycles and a transatlantic crossing around 2012.


Virgin Nigeria to lose ‘Virgin’ brand name next month

Sir Richard Branson: Virgin Nigeria has been a breath of fresh air in the Nigerian aviation industry with a strong focus on safety and higher standards. It has a real opportunity to grow strongly as the Nigerian economy itself grows from strength to strength in the year’s to come.

Virgin Nigeria is to rebrand in a month’s time to reflect discontinuation of shareholder Virgin Atlantic‘s day-to-day involvement with the carrier, and its new strategic direction.

Several names are being considered for the rebrand – among them ‘Nigerian Eagle’ and ‘Air Nigeria’ – ahead of the change which must be undertaken by 7 July.

Shareholders of the Lagos-based carrier are also meeting this week to discuss future funding for the airline.

Virgin Atlantic, which holds 49% of the airline it established five years ago, is “not extending brand rights”, says a source familiar with the process – adding that Virgin Nigeria, which is looking for additional capital, “doesn’t need the branding cost”.

Last year Virgin Atlantic stated that it planned to sell its stake in the carrier and allow it to stand alone as a wholly Nigerian-owned venture.

Long-term Virgin Nigeria managing director, Conrad Clifford, will be succeeded on 18 June by Dapo Olumide.

He will oversee Virgin Nigeria’s development of local connections with its Boeing 737 and Embraer regional jet fleet, after the airline opted to discontinue long-haul services earlier this year.

A spokesman for Virgin Atlantic says it “supports the strategy of focusing on the domestic market, which is a huge opportunity”.

He adds that the UK carrier “remains open to offers” for its 49% shareholding in “what has been a successful business in terms of a strong safety culture and growth in Nigeria”.

Virgin Atlantic says it “always intended” to pull out from the Nigerian carrier within about five years, and last week brought technical co-operation to a close, essentially ending its day-to-day participation in Virgin Nigeria’s operations.


Boeing shakes off tough year for 747-8

Click here for more news / Clique aqui para mais notícias

By Stephen Trimble

Veteran Boeing programme executive Mohammed “Mo” Yahyavi inherited the 747-8 programme in February as development of the next-generation widebody was still emerging from a cloud of delays and cost overruns.

Coming only three months after Boeing chief executive Jim McNerney expressed “frustration” with 747-8 issues, leading to widespread doubts about Boeing’s support for the programme, Yahyavi appeared to be facing a classic turnaround situation.

Perhaps surprisingly, Yahyavi, an Iranian-born and Italian navy-trained engineer, says he arrived at the 747-8 programme in February to find a fundamentally solid plan for development and production, and a strong staff already in place to carry it out.

“I saw a very strong, capable team in place,” says Yahyavi. “This is a very important programme for the company and industry, so there has been a really good focus at the programme level, with all aspects of best practices in place.

“It came to me very quickly that I did not really need to change anything,” he adds. “I believed I could follow this process already in placeand act like a cheerleader and get the team going.”

Yahyavi’s public confidence for the 747-8’s existing plans and team marked a major mood reversal in the development programme.

After all, within the past 10 months, the 747-8 has endured two announced schedule delays, its second unexpected leadership change and a confidence crisis sparked by an equivocating remark by McNerney in January about Boeing’s commitment to the programme.

After a four-year marketing effort, the 747-8 Intercontinental has attracted only a single firm deal from a passenger airline – 20 orders for Lufthansa – but a further seven have been sold to VIP customers.

Asked by an analyst in January whether Boeing could cancel the slow-selling 747-8I, McNerney replied: “We still see a viable business proposition here. Now, obviously, if we ever got to a point where we didn’t, we’d have to work with our customers to come up with another answer.”

Boeing’s communications staff quickly followed up to clarify that the company remains solidly behind the 747-8I programme.

Since McNerney’s remarks in January, the 747-8I design team has also continued to make progress. As of late May, the company had completed about one-third of the engineering design drawings required to start the building process.

UNWAVERING CONFIDENCE

Moreover, Yahyavi expresses an unwavering confidence for the future of the 747-8I, deliveries of which are not now expected until the third quarter of 2011, with initial aircraft being for VIP customers.

“We are fully, fully committed, dedicated and invested in this product,” says Yahyavi. “Absolutely, there is no doubt in my mind. I have the full support of the company. I have no shortages as far as parts or resources are concerned. Everything is in place.”

In early May, a Bloomberg reporter quoted Yahyavi confidently predicting that Boeing would sign a new order for 747-8Is in the near future. Asked about the comments a few weeks later, Yayhavi would only say he is “optimistic” about the possibility of new orders.

“We are engaged in very active discussions with several airlines about this airplane,” he says, adding that the airlines want to “understand more” about the aircraft.

The market is also waiting to know more about the 747-8 Freighter, the first of the two variants scheduled to enter service. The first components of the aircraft began arriving in August at Boeing’s final assembly plant in Everett, Washington. As the sections and parts began being delivered, Boeing realised its production system had failed to keep pace with design changes. The programme, then led by Ross Bogue, began a review of the production system which concluded that the delivery schedule was unrealistic.

In the midst of the production review, Boeing also faced a 57-day labour strike called on 6 September by the International Association of Machinists and Aerospace Workers (IAM).

By mid-November, the workers had returned to the final assembly line. Boeing, however, was forced to announce a delay of up to nine months for the 747-8F, now scheduled for the third quarter of 2010. The 747-8I’s first delivery slipped from late 2010 to the second quarter of 2011. In April, Boeing’s decision to slow the delivery rate for 747-8Fs also meant the first 747-8I delivery would be delayed again to the third quarter of 2011.

Despite the production breakdowns, Yahyavi says the programme is still on track to achieve first flight by the end of the year. The programme has completed assembly of the 27.2m (89ft) forward fuselage section, including the upper deck. That section has also been moved from the final assembly installation tool for sealing and testing before starting the systems installation process.

“On the first airplane, we are almost about halfway to completion of assembly,” Yahyavi says. All the major fuselage sections for aircraft 1 are at the Everett plant. The first aircraft’s wing has also been completed, including the struts and pylons for the General Electric GEnx-2B engines.

Meanwhile, GE’s 747-100 flying testbed, based in Victorville, California, is about halfway complete on certification tests for the aircraft’s conventional bleed-air propulsion systems, says Yahyavi.

Further, the fuselage sections for aircraft 2 and 3, which comprise the flight-test fleet, are also in work on the final assembly line.

“We obviously want these airplanes to come together in a certain period of time so we can have a very efficient and quick flight test,” says Yahyavi.

DELIVERY WINDOW

He also estimates that the time between first flight of the 747-8F and delivery to launch customer Cargolux will span 10-11 months. The scheduled delivery window for the third quarter of 2010 ends on 30 September, which means first flight must be before 30 November for Boeing to meet its current schedule.

At the same time, the status of the air cargo market has declined dramatically because of the ongoing global economic crisis. However, the worsening financial outlook for the 747-8F’s customers has not yet translated into lost orders for Boeing.

“We have no cancellations on the freighter,” Yahyavi points out. “All of our customers love the airplane – and they want to stay with the airplane.”

In April, Boeing decided to slow production output for all its widebodies except the 787. That change allowed it to adjust its delivery schedule to align with the recent demands of its customers, including on the 747-8F line. “There is no doubt the freighter market is soft and we are working directly with every single customer to accommodate their plan and their schedule,” he says.

On top of the slower output off the production line, Boeing has also received requests from 747-8F customers to defer some delivery slots, allowing some customers to move ahead, says Yayhavi.

SCHEDULED DELIVERY

However, the opportunity created by the deferrals will not lead to changes in the 747-8I schedule. Those customers – either Lufthansa or VIP configuration buyers – will not be able to receive any aircraft earlier than the current scheduled delivery in the third quarter of 2011, says Yayhavi. “That is not in our plan right now.”

Boeing is also making progress on its weight reduction plan for the 747-8F. Last year, Bogue disclosed that the 747-8 exceeded its weight target by at least 1%. With the freighter design about 98-99% complete, Yahyavi says: “We have some weight challenges there, but it’s not huge.”

The programme is looking at all opportunities to remove weight from the aircraft, he adds, including the fuselage and propulsion system. As a sign of progress, the fourth aircraft in production beat the weight of its predecessor in final assembly.
