I don't want to be on a pinglist,
What is a winglet?
Thanks
This AeroMexico 737 has winglets on the wing tips.
Blended Winglet Equipped Boeing 757 Makes First Flight
Another Aircraft Model Enters the Sky with Blended Winglets - Landmark Milestone Achieved
SEATTLE, March 11 /PRNewswire/ -- On March 9th a Continental Airlines Boeing 757-200, outfitted with 8 foot 2 inch tall Aviation Partners Boeing Blended Winglets, flew from Everett, WA to Los Angeles with a brief stop en route at Boeing Field Seattle. "The first flight was a complete success," says Aviation Partners Boeing Vice President of Programs Jay Inman.
"From an airline perspective, this is our most significant Blended Winglet Program ever. With this technology, Boeing 757-200 operators will experience block fuel improvement of up to 5%, saving as much as 300,000 gallons per aircraft, per year for every Blended Winglet Performance Enhanced 757-200," said Aviation Partners Boeing Vice President Sales and Contracts Patrick LaMoria.
FAA certification of 757-200 Blended Winglets is anticipated in May 2005 with first customer installations beginning in July. Initial launch customers Continental Airlines and Icelandair are the first operators that will take advantage of patented* Blended Winglet Technology on their 757-200's.
"Market interest in this program has been unprecedented," says Aviation Partners Boeing CEO Mike Marino. "The 757-200 is a very popular aircraft that has been coming up in value lately. More and more airlines are looking to increase the utilization of one of the most efficient aircraft every designed on a cost per seat basis. Blended Winglet Technology, now available for the 757-200, is helping to make this possible."
Aviation Partners Boeing expects to Performance Enhance the majority of the 600 plus existing fleet of 757-200s with revolutionary Blended Winglet Technology. Operator benefits include: a block fuel improvement of up to 5%, approximately 200 nautical miles of additional range or up to 10,000 lbs. of incremental payload capability, improved second segment climb, enhanced operational flexibility (such as trading improved fuel burn for faster cruise speeds), improved takeoff performance out of high, hot, or obstacle limited airports, reduced engine maintenance costs, enhanced aesthetic appeal, increased aircraft residual value, and a range of environmental benefits that will equate to an economic payback period of less than 3 years for most operators.
"The 757-200 Blended Winglet Program is a tremendous milestone for us and very exciting from a sales perspective," says Aviation Partners Boeing Chairman Joe Clark. "This landmark program will translate into about 180 million gallons in annual fuel savings when the entire fleet of 757-200's is upgraded with Blended Winglet Technology. Anytime you can enhance the productivity of an existing asset we feel it is a wise business investment."
I recall reading at some posts on Free Republic that some pilots do not want to fly Airbus aircraft due to perceived safety issues, and have gone as far as undergoing extensive retraining even though that may have a significant impact on them.
Can any pilots out there comment on whether this is true or not?
I flew on an A320 today, and will be on an A330 in a few days, I have no problems with them, they make good planes.
Hey, they can always tow it to the show! Image is everything!
Airbus' ideal for long distance flying is not mine. If you've ever watched rush hour at JFK, that is Airbus' vision. Imagine 20-30 of these things waiting in line to take off. I'd much rather be able to catch a direct flight at DFW or IAH than have to go through JFK.
Yeah. . .I've had five internation flights this year and I can't stand LAX, JFK and IAD.
Hopefully it goes better for Airbus than the 1988 one did...
The last time I flew Airbus, stuff in the cabin was falling apart, and the plane was making these weird noises. I've never been afraid to fly, but on that trip, I was seriously giving thought to changing my return flights to be something other than Airbus, and I could not wait for that flight to be over...
A wiglet reduces the loss of lift at the wingtip producing a more efficient wing. Better wing equals better fuel economy.
That's because LAX and JFK still haven't completely updated their international terminals to modern standards. This is totally unlike SFO (San Francisco International Airport), which has a totally new International Terminal that opened at the end of 2000 designed to support more 747-400 operations and even has four gates that are ready to support the A380-800 right now. 
By the way, I've heard that Airbus will start taxiing tests on the A380 prototype within the next few days.
On a Boeing product if you want to wave off on auto pilot you start with the Take Off/Go Around button on the throttles. This brings the power up first and makes inputs to the flight director system, as well.
All depends on the airline, my airline, which I retired from and have free flights on for life flies 320/319, no problem, I'm no fan of the A300 or the A300-600, but the A330 is a joy to be a passenger on.
I don't care for the MD-11, a crappy plane, poorly built and thankfully being used for cargo mostly.
The winglet's function is to break the vortex that forms at the tips of the wings. A vortex creates substantial extra drag. If you've heard of ground effect, where an airplane has less drag close to the ground, this is because the ground breaks the vortex. Winglets have this same effect, though require high structural strength at the weakest part of the wing.
