Agreed NYE.
A voice of reason in a mad world.
RIP HLS

RIP.

There are far too many Tom and Dicks in this world, but not nearly enough Harrys.
He can now rest in peace knowing that he made a difference.

Nairobi attack: How 'fearless' SAS hero who stormed Kenya hotel 'saved many lives' As gunfire rang out and screaming and bloodied civilians fled, the lone, balaclava-clad figure stormed the building without hesitation www.mirror.co.uk/news/world-news/nairobi-attack-how-fearless-sas-13868452This is the kind of person that deserves a Knighthood, not the likes of politicians, Sportsmen and Billionaire tax-dodgers - what a bloody hero this man is.

We fly on the 737-800 with winglets.
I'm not worried...

Winglets are designed to reduce the effects of vortex shedding. My understanding of this is that Boeing have previously identified a software issue which was potentially the cause of the recent Lion Air crash. The flight profile of the crashed ethiopian aircraft indicates a problem maintaining a steady climb rate and therefore unlikely to have anything to do with winglets.
If it's any consolation, I was coming back from a business trip to Italy some years ago and driver clipper a parked aircraft with his wingtip. We parked up and a fitter with some step Ladders dashed out and patched it up with duct tape and off we went.
Winglets won't be the problem.

Thanks very much for the insight, though, mate - it made for interesting reading.

Just to be clear, by vortex shedding, I assume you mean like F1 cars when they create 'dirty air for the cars behind?

I could tell a few tales of tense flying moments mate, clear air turbulence being by far the worst. It's a phenomenon associated with air pressure or rather the lack of it. The result is that the aircraft drops (plummets would be nearer the mark). Believe me, adrenalin is brown!

Just to be clear, by vortex shedding, I assume you mean like F1 cars when they create 'dirty air for the cars behind? There is a famous film clip which I'd be able to upload if I was sufficiently whizzy on a phone. You'll probably get it on YouTube. It shows an aircraft flying at low altitude through smoke. Aircraft create vortices which flow normal to the direction of flight (unlike cars) and away from the fuselage. It's caused by airflows leaving the wings. In large aircraft like the A380 it can be very destructive and would almost certainly cause small aircraft to have serious problems remaining airborne. For that reason there is a minimum time period before aircraft can fly through airspace recently vacated by others. They have to wait for the air to settle down.

Haha, was just disturbed by the boss. The issue with dirty air behind a car is similar yes. Other examples would include tall modern factory chimneys. Very often manufactured from aluminium, they have a small fin spiralling down around the outside. That's to prevent vortex shedding. If not, the turbulence would bring the chimney down. Cutwaters on the piers of stone bridges is another, the taper close to the bottom, just above the surface of the water to the rear of the pier is not for decorative purposes, it allows the water to flow off the surface of the pier with a minimum of turbulence.

Cheers for that excellent and informative insight, mate - very much appreciated!
