Hi Captain Doug
A question popped up in my head the other day and I was wondering if you could address it in either your blog or in enRoute.
If winglets (as found on newer jets such as ERJs and next gen B737) produce less drag aerodynamically and more fuel efficient, then why are they not found on the newest big jets such as A380 and B777?
Leon. Excellent question. If you look at the B777's wing you'll see it has a unique twist near the wing tip. I believe it's called a raked wing.
Boeing determined by increasing wing area and by fine tuning the design it was not necessary to add winglets. Winglets can be an issue in tight spots on the ground as well. They just don't go up but bend outward on many aircraft.
I was going to say Boeing didn't want to admit winglets worked because it was Airbus that lead the way. Having said that the B747-400 and the new
B737s have winglets. Boy, I know I'm going to get flak from the Boeing camp on this. LOL
Heck, since I'm on a roll what about that control column? The new B787 still utilizes that "thing" between a pilot's legs. Sure you need it
for take off and landing, but what about the 10 to 14 hours in between? Which leads me to the one of many Boeing/Airbus jokes. "An Airbus pilot
has nothing between his legs."
Leon, hopefully this question will stir the pot and will generate the real answer about B777's winglets.

Doug, for gods sake quit being sorry for nothing.Your blog is by far the best out there. I look forward to reading it at all times. My best buddy is an F/A for Delta, 32nd year this year and I turned him onto your blog also. Now he is also flying the A319+A320. Hope you blog for years to come!!. Hope tp see you and your bus at SFO. Yeah I know you guys and gals dont like it but it is great for spotters.Great views of the 28s and even better spotters point at the hold short line of 01 right. KEEP IT UP!!

He is chief pilot of a small charter company and had an interview with Air Canada.
He is still waiting for the results. I have my fingers crossed.
I hope I didn't miss anybody. Thanks everyone.

Before I go I'd like to thank Chris St. Clair at the Weather Network for having me in this morning for a few questions on weather. You should see my "mug shot" now and again for the next few days...in the meantime...anyone want to come to Mexico City this afternoon? ....gone flying.... Captain D
