Hi guys!

I was just browsing through pictures when I noticed that an SQ bird had these orangey tip things on the back of the wing strut type things! (I'm sure someone could correct me on the lingo!) I looked around for earlier pictures of the plane and found that they were without these orange tips!
Here's the plane with and without this orange bits!

They are fairings around the flap mechanisms and they are often called canoes. As for the orage tips, well I have always wondered that myself.

Those parts are called canoe fairings. They are an aerodynamic cover for the flap mechanism.

The tip is usually there to make ground crews away of the the canoe fairings. In particular, catering trucks will come fairly close to them when they service doors L4 and R4.

No idea.

Safety. Think it is part of their effort to reduce things from driving into them. Probably helps with insurance as well. If the flaps are down those canoes can be a hazard. Bump into one and the plane is going to be out of service. Orange paint is much cheaper.

Many years ago, ANA painted their jet engine hubs with a swirly white spiral to scare off birds and make it easy to tell the fan was spinning... soon every carrier got into the act and now most engines have them. It was done for safety.

It's been common practise for the last 30-40 years for these birds:

Same with the orange or red vortilons on the ERJ. Apparently they're pretty sharp and at just the right height to bump your head.

What is even weirder is that when AS got their first 73G, they painted black hashmarks on the wingtips. For this reason, I have no clue to why. I even asked the painter while he was doing it what it was for. He didnt have a clue himself. N607AS got the first painting of the wingtips in black hashmarks.
