Airlines Slow Down To Save Money

U.S. Airlines have ordered their pilots to slow down to reduce fuel consumption.They say the move will add minutes to flight times whilst, at the same time, save millions in fuel costs.
However, the strategy will not be taken up by the large British airlines, even though the price of jet fuel has shot up by more than 70 per cent in the past year.
Both British Airways and Virgin said they have already introduced fuel-saving measures which they believe are more effective than those adopted by their American counterparts.
Insisting that reducing speed saves fuel in certain speed ranges, the U.S. operators are introducing slower cruising speeds on both domestic flights and long-haul routes to Britain and Europe.Northwest Airlines, which is in merger talks with rival Delta to become the world’s biggest carrier, said it saved 162 gallons of fuel on a Paris to Minneapolis flight recently when the pilot cut his average speed from 542mph to 532mph. The speed reduction only added eight minutes to the flight time but saved the airline nearly £300 ($600).
Northwest number crunchers calculate that by slowing down just slightly they will save £300,000 this year alone just on the route between Los Angeles and Hawaii.
Another U.S. airline, Southwest, estimates it will save £21million this year by adding one to three minutes to each flight.
Budget airline jetBlue said it would save nearly £8million.
United Airlines recently followed B.A’s tactic by installing similar flight-planning software, which it believes will save £10million a year. BA’s software shows pilots the best altitude and speed to allow optimum use of fuel. Experts said most passengers would not notice the slightly longer times.Virgin’s Paul Charles said: “We believe our fuel-saving measures are better than the Americans.” Virgin is concentrating on reducing the weight of planes by using light carbon-fibre fittings. “We will save many millions of pounds more with our weightwatchers programme than the Americans can save by slowing down,” said Mr Charles. American carriers are struggling with older, less efficient fleets than British companies, he added.
BA has also ordered its pilots to use only one engine while taxiing around airports. And both BA and Virgin also try, where possible, to use ‘continuous descent’ when landing, so planes glide smoothly down. The alternative is to descend in steps, a process which uses a lot of fuel but is sometimes essential at busy airports.
But a word of caution came from Bob Mann, a New York-based airline consultant, who warned that reducing speed can increase maintenance which means aircraft spend less time in the air. “Everyone is looking for that ” sweet spot” when an airplane flies at the highest speed for maximum fuel economy,” Mr Mann added yesterday.

A 40 percent uplift in fuel efficiency, together with a 15 percent reduction in CO2 emissions are planned for 2012.It plans to do this by introducing a new engine capable of running on waste derived bio-fuel as well as petrol (gas). And all this without sacrificing performance.
Mercedes-Benz launched a new “green” flagship S-class limousine.The S400 BlueHybrid, which uses lithium-ion battery technology, does 35mpg with CO2 emissions of only 190g/km. It is no slouch though because it can do 0-62mph in 7.3 seconds. Top speed is a limited 155mph
