How do aircraft “back-up” from the gate by themselves?

first_imgVietjet’s interline agreement with Qatar will make it easier for passengers to connect with the Gulf carrier. ApprovedIn a fully approved procedure, an aircraft can back away from the gate under its own power under reverse thrust. However, before the jet can move backwards, it must roll forward slightly before the reversers can be deployed, and to move off of the tire’s ‘flat spot’ created when the aircraft sits parked on the ramp for any length of time.A critical component necessary for this procedure is the ramp agent or ground marshaller. After engines are started with the jet still parked at the gate, the marshaller signals the pilot in command when to move forward, and then using a rotating motion rapidly moving the signaling wands one-over-the-other, indicates exactly when to deploy the reversers and back away from the gate. When the aircraft has safely cleared the ramp area, the reversers are closed, throttles are brought back to idle, and the airliner can then taxi out to the runway.

Indaba to tackle SA mining challenges

first_imgLabour disputes, rising costs and slowing demand due to a stagnant global economy are the major issues faced by South Africa’s miners. How the country plans to address these challenges will be a key focus of the Investing in African Mining Indaba taking place in Cape Town this week.More than 7 500 delegates, representing 1 800 international companies, will be in South Africa to discuss and debate mining interests in Africa.Mineral Resources Minister Susan Shabangu told a Brand South Africa gathering at the Cape Sun on Sunday night that the transformation of the industry was fundamental to helping the country overcome its dual challenges of poverty and inequality, and ensuring that everyone benefited from South Africa’s mineral wealth.The mining sector roundtable, hosted by Brand South Africa, KPMG and CNBC Africa, included a panel discussion about the opportunities for growth offered by transformation.‘No plans to nationalise mines’ In a pre-recorded video address, Shabangu said improvements to the regulatory framework had been made with the intention of attracting investment, adding that the government had repeatedly reassured investors that it did not have plans to nationalise South Africa’s mines.“The way to balance profit and social responsibility is to work together,” the minister said. “Partnerships are key.”Shabangu urged investors to view transformation as a positive, not a negative factor: “See yourself as contributing to South Africa, the gateway to Africa”.Miller Matola, the chief executive of Brand South Africa, said it was important to discuss ways to ensure the sustainability and success of what is a key sector of the South African economy.“We must find ways to take advantage of opportunities that are presented by a continent that is clearly on the rise,” he said.‘New solutions needed’ Godfrey Olifant, the deputy minister of mineral resources, said that although South Africa could do better, growth in the industry was strong and he was comfortable that “we are doing well”.Rivalry between unions and the importance of beneficiation to employment creation were not new issues, Olifant said. The challenge was rather to find new solutions to old problems.Change required commitment, he said, and it was time “to do something new”.Also participating in Sunday night’s roundtable were Chamber of Mines of SA vice-president Khanyisile Kweyama, South African Mining Development Association president Bridgette Motsepe Radebe, and Leslie Maasdorp, president of the Southern Africa at Bank of America Merrill Lynch.The organisers of the four-day Investing in African Mining Indaba say the event has injected more than R336-million in revenue into the Western Cape’s economy over the past five years, creating 3 000 direct or indirect jobs.More than half of the delegates attending the event come from Africa, while 18% are from Europe, 12% from Australia, and 8% from North America.SAinfo reporterlast_img read more

Food prices down for Easter

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Lower retail prices for several foods, including eggs, ground chuck, sirloin tip roast, chicken breasts and toasted oat cereal resulted in a significant decrease in the American Farm Bureau Federation’s Spring Picnic Marketbasket Survey.“As expected due to lower farm-gate prices, we have seen continued declines in retail prices for livestock products including eggs, beef, chicken, pork and cheese,” said John Newton, AFBF’s director of market intelligence.The informal survey showed the total cost of 16 food items that can be used to prepare one or more meals was $50.03, down $3.25 or about 6% compared to a year ago. Of the 16 items surveyed, 11 decreased, four increased and one remained the same in average price.Egg prices are down sharply from a year ago and also are down slightly from the third quarter of 2016.“Egg prices continue to move back toward long-run average prices following the bird flu of 2014/15,” Newton said. “The Agriculture Department is currently monitoring bird flu detections in the Southeast U.S. If detections continue, retail poultry prices could feel an impact due to lower exports or changes in supply.“As farm-gate prices for livestock products have declined and remained lower, prices in the retail meat case have become more competitive,” Newton said.

Retail price changes from a year ago:• eggs, down 41% to $1.32 per dozen• toasted oat cereal, down 15% to $2.83 for a 9-ounce box• sirloin tip roast, down 13% to $4.95 per pound• ground chuck, down 10% to $3.92 per pound• chicken breast, down 6% to $3.17 per pound• apples, down 6% to $1.55 per pound• flour, down 5% to $2.36 for a 5-pound bag• shredded cheddar cheese, down 4% to $4.10 per pound• deli ham, down 3% to $5.42 per pound• bacon, down 3% to $4.65 per pound• potatoes, down 1% to $2.68 for a 5-pound bag• bagged salad, up 6% to $2.34 per pound• white bread, up 2% to $1.72 per 20-ounce loaf• orange juice, up 1% to $3.22 per half-gallon• whole milk, up 1% to $3.27 per gallon• vegetable oil, no change, $2.55 for a 32-ounce bottlePrice checks of alternative milk and egg choices not included in the overall marketbasket survey average revealed the following: 1/2 gallon whole regular milk, $2.10; 1/2 gallon organic milk, $4.20; and one dozen “cage-free” eggs, $3.48.The year-to-year direction of the marketbasket survey tracks closely with the federal government’s Consumer Price Index (http://www.bls.gov/news.release/cpi.nr0.htm) report for food at home. As retail grocery prices have increased gradually over time, the share of the average food dollar that America’s farm and ranch families receive has dropped.“Through the mid-1970s, farmers received about one-third of consumer retail food expenditures for food eaten at home and away from home, on average. Since then, that figure has decreased steadily and is now about 16%, according to the Agriculture Department’s revised Food Dollar Series,” Newton said.AFBF, the nation’s largest general farm organization, began conducting informal quarterly marketbasket surveys of retail food price trends in 1989. The series includes a spring picnic survey, summer cookout survey, fall harvest survey and Thanksgiving dinner cost survey.According to USDA, Americans spend just under 10% of their disposable annual income on food, the lowest average of any country in the world. A total of 117 shoppers in 31 states participated in the latest survey, conducted in March.last_img read more

The laboratory expects to study a variety of new green building materials, including hybrid poplar lumber engineered to be three times stronger than old-growth Douglas fir, new types of environmentally friendly concrete, and building insulation made from recycled plastic.Portland State University (PSU) will receive $651,000 to establish the Green Building Research Laboratory. The lab will specialize in building- performance monitoring and the use of infrared cameras for evaluating wall assemblies, ceiling assemblies, and windows. Researchers at PSU also plan to study how occupant behavior affects building energy use.last_img read more

Why Solar Microgrids Are Not a Cure-All for Puerto Rico’s Power Woes

first_imgThe power system before MariaPrior to Maria, Puerto Rico had one of the largest public power authorities in the U.S., known as PREPA, serving a population of 3.4 million people from 31 power plants, 293 substations and 32,000 miles of wire. Almost half its generation was from old, very expensive oil-fired plants, resulting in prices of about 22 cents per kilowatt hour, among the highest in the U.S. The island has several photovoltaic (solar electric) farms but gets about 46% of its power from oil and only about 3% from solar.At the center of all this is PREPA and its outsized role in Puerto Rico. With $9 billion of debt, PREPA has been part of the contentious refinancing process that ultimately required congressional action. PREPA is also the largest employer on the island, with strong connections to the island’s leadership, so proposals perceived to adversely impact PREPA can be difficult to enact. Recently the island has established a new energy commission called PREC with oversight over PREPA’s plans, spending, and rates.The PREC’s efforts at reform underscore the enormous challenges the utility faces. In September 2016 the PREC issued an order directing PREPA to convert some of its oil plants to gas, renegotiate some high-priced renewables contracts, and purchase more renewable energy.In April 2017 PREPA issued a new financial plan with starkly grim prospects: a $4 billion maintenance backlog, the loss of fully one-quarter of its sales in the next 10 years, and continued red ink as far as the eye can see. Meanwhile, renewable power developers who have tried to build plants on the island have encountered great difficulties, as chronicled in this blog post.Then, just before Maria, PREPA declared bankruptcy. Maria therefore destroyed the grid of a system that was already bankrupt, having trouble maintaining its service and paying its bills, resistant to renewable interconnections, and politically difficult to reform.

Solar Industry Offers Help in Puerto RicoWhy We Still Need to Discuss Grid DefectionAn Introduction to the Duck CurveA Neighborhood Microgrid Takes Shape in Brooklyn Getting Power From Solar Equipment When the Grid is DownVermont Utility to Develop New Grid TechnologyWhy a Vermont Utility Welcomes Solar By PETER FOX-PENNERIn addition to its many other devastating human consequences, Hurricane Maria left the island of Puerto Rico with its power grid in ruins. Power was knocked out throughout the island, with an estimated 80% of its transmission and distribution wires incapacitated. When hospitals and other critical users could not get backup power and water supplies ran low, an extended outage became a humanitarian crisis that has yet to be resolved.This shameful outcome should have been avoided with strong, swift federal leadership. Yet more than five weeks after the storm, only about 40% of the grid has been rebuilt, and service remains unreliable even where power is restored.As the recovery process inches its way forward, the questions many are asking go like this: Why are we rebuilding the grid to be the same as it was before the storm? Can’t we use this as an opportunity to create a more modern, resilient, renewable power system? Isn’t this the perfect opportunity for an upgrade?center_img The answer to these questions, from my perspective having worked with and researched the power industry for four decades, has little to do with technologies and everything to do with some nearly insurmountable financial and governance challenges. There is a path forward, but it will not be easy. A sustainable, resilient path forwardPuerto Rico’s citizens have endured great hardship and tragedy. We as a society certainly owe it to them to do whatever we can to lessen the damage from the next hurricane and speed power restoration. However, the path to a sustainable and resilient grid for the island is not as simple as air-dropping solar panels and other equipment onto the island and assuming all will be well. The suggestion that restoring power by replanting the current poles and wires will foreclose a more distributed solution isn’t correct, nor is it the most equitable way to restore power to everyone as quickly as possible.This isn’t to say that the installation of fully independent solar systems and microgrids should be discouraged in any way. With the important provision that the hardware is maintained properly, the more solar and storage we can get onto the island sooner the better.At this point, Puerto Rico’s grid is being rebuilt essentially as it was before.But even as the grid is rebuilt as quickly as possible, the planning and engineering should begin on how to migrate the grid to smaller sections that self-island. This must include all the main aspects of power system development and operation, including financing, ownership, operation, and maintenance of the systems.The only logical way for Puerto Rico — and every other storm-prone electric system — to become a series of resilient and clean microgrids is to first get the entire grid functioning and then to create sections that can separate themselves and operate independently when trouble hits. Proposals for rebuilding with microgridsThe challenge, then, is to 1) restore energy access as quickly as possible; 2) begin to build a long-term resilient and operable grid; and 3) reform a broken regulatory system. In the wake of the storm, clean energy experts and businesses saw this as the perfect opportunity to start over.“Puerto Rico will lead the way for the new generation of clean energy infrastructure,” one solar CEO asserted, “and the world will follow.” Elon Musk also famously tweeted an offer to solve the island’s energy problems with Tesla solar systems and batteries.With an array of solar panels and batteries, a group of buildings, such as a hospital or a neighborhood, can power itself and operate independently in the case of an outage with the central grid — called “islanding” in industry parlance.Provided they can be paid for and operated safely, quickly setting up these solar microgrid systems is an excellent measure that is both stopgap and long-term contributor. These systems can be set up in a matter of days, providing enough power to help neighborhoods with critical power needs, such as cellphone charging, powering cash machines, and providing electricity service for health care and first responders.However, these systems cost tens of thousands of dollars, and there is currently no substantial way to pay for them other than the kindness of strangers. Three-and-a-half million people would need perhaps 350,000 of these systems — at a price tag in the billions — to provide only a fraction of most families’ power needs.Even if costs were not a consideration, these distributed systems aren’t a substitute for the grid. Many people think that microgrids don’t need poles and wires, but if they serve more than one building they use pretty much the same grid as we use today.Once the grid is rebuilt, the new grid-independent systems should then become part of a series of new community microgrids, or networks of multiple solar panel installations backed up by storage. These interconnected systems would be able to “island” together to keep the whole community running at partial if not complete levels of service. With the necessary planning and approvals, new community power organizations could be set up — perhaps separate from PREPA — to finance the conversion of local grids to a more resilient form.So there is a path from the current grid to one that is far cleaner and more resilient, but it’s not simple or quick. It would require melding complete and rapid restoration of power with a major infusion of capital.Changing the base of generation from PREPA’s aging, inefficient fleet to clean sources is an essential part of this path. However, even at an extremely fast pace, it takes months to plan the economics, financing, and engineering of this transition. More commonly, it takes years and careful economic and financial planning to raise the billions of dollars of capital needed and then spend it wisely.last_img read more

Forgiving loans offers BC First Nations opportunities says grand chief

first_imgTina HouseAPTN NewsGrand Chief Ed John of the First Nations Summit says the forgiving of loans taken out to negotiate comprehensive claims or treaties will have a huge impact on First Nation communities.“How big a deal is it? Its a $1.4 billion deal and to me, when the loans are forgiven and off the books for First Nations, it provides those communities opportunities to raise revenues for other business opportunities for other development in the communities,” said John, head of the B.C. First Nations Summit.In the federal budget delivered in March, the Liberals announced that the government would be forgiving loans that were taken out by First Nation communities to prepare for negotiations.Many went into debt for millions of dollars.B.C. Treaty Commissioner Mary-Ann Enevoldsen is the former chief of the Homalco First Nation in B.C.She said that forgiving these loans is a step towards reconciliation.“The issue of taking on loans for the protection of our rights title and culture was very devisive, and controversial,” she said. “It was counter productive to advance our treaties on behalf of our nations it gave fuel to people who opposed our efforts and it left a negative cloud over the treaty processes goals.”Crown-Indigenous Relations Minister Carolyn Bennett made the announcement in the backyard of former attorney general and justice minister Jody Wilson-Raybould.Media stories have reported a rift between the two ministers over the failed Indigenous rights framework agreement.Bennett called the situation unfortunate and that the government is pressing on.“These kinds of conversations discussions about recognition and implementation of rights should be done and paid for by Canada that it is now going forward contribution agreements where we pay for what it will take to be able to reach an agreement and nation to nation re-build the nations,” she said.Bennett said there are a few more steps within government to finalize the details.But letters should be going to affected communities [email protected]@inthehouse7last_img read more

Hearing on Khaledas bail pleas adjourned for Wednesday

first_imgKhaleda Zia. File PhotoThe High Court on Tuesday adjourned until Wednesday the hearing on two petitions filed by Bangladesh Nationalist Party chairperson Khaleda Zia seeking bail in two cases, reports UNB.An HC bench of justice AKM Asaduzzaman and justice JBM Hassan passed the order after partially hearing the petitions.Earlier on Monday, the HC deferred the hearing on the petitions filed by the BNP chairperson’s lawyers for Tuesday.One of the cases was filed in Cumilla on charge of plotting to carry out subversive acts and another in Narail on charge of defamation, said BNP legal affairs secretary Kaisar Kamal.On Sunday, the HC granted permission to Khaleda for filing the bail petitions after her lawyers prayed for it.The Appellate Division earlier on Wednesday upheld the High Court order that had granted bail to convicted BNP chairperson Khaleda Zia in the Zia Orphanage Trust graft case.However, the BNP chief was not freed from jail as Khaleda was shown arrested in the cases filed with different police stations in Cumilla, Dhaka, Narail and Panchagarh.The BNP chairperson is now facing a total of 36 cases.Eight people were killed and at least 20 others injured when miscreants hurled a crude bomb at a bus at Jogmohanpur in Chouddagram of Cumilla district during the BNP-led alliance’s movement on 3 February, 2015.On 21 December, 2015, Khaleda Zia at a discussion at the Institution of Engineers, Bangladesh raised questions about the actual number of liberation war martyrs saying, “There’re controversies over how many were martyred in the liberation war.”Reacting to Khaleda’s remark, a defamation case was filed against her with a Narail court on 14 December.Meanwhile, the HC will likely to hear two more petitions of BNP chairperson Khaleda Zia on Wednesday, seeking bail in two other cases.Earlier, in the day, the BNP chairperson’s filed the petitions with the High Court seeking bail in two separate cases.One of the cases was a defamation suit filed by Bangladesh Jananetri Parisad President AB Siddik on 3 November, 2016 against Khaleda Zia for distorting history of the liberation war, demeaning the national flag and map.The other was filed by journalist Gazi Jahirul Islam on 30 August, 2016 accusing Khaleda of observing birthday on 15 August on false information.Khaleda Zia’s lawyer filed the petitions with the HC bench of justice M Enayetur Rahim and justice Shahidul Karim after taking prior permission from the court.last_img read more
