And what are those two iron triangles beneath the wing (if that's what it is)?

I think that they are part of the machinery for the flaps. They always seem to be at the end of the flaps on most wings. Maybe someone could provide a more tehnical answer.

I'd guess Embraer also, but not ERJ...maybe EMB-120? Doesn't look like the ERJ tip/light assembly to me.

I would guess it could be a GA aircraft. I don’t think Brasilia has such things (the yellow triangles), and I am pretty sure it has boots to the end of the wing (this does not). Not to mention it would be hard to get such a picture without the prop being in it.

And an ERJ has a swept back wing.

Which was what I was thinking, but I've never seen those triangular fins on anything else than a ERJ. The Brasilia doesn't have them.

Can't be a EMB-120 or 110 for that matter, due to the lack of de-ice boots. Only Embraer I think it might be is the EMB-312 Tucano, but I doubt it.

I'm thinking more like an Ag type plane like a Maule or something. The "triangles" may be hard points where tanks of chemicals are attached. Looking forward to the real answer.

They are called Vortelons (sp) and direct the air to better flow over the ailerons. Looking at that picture it sure looks like an Embraer ERJ

There are 3 of them present in photo and 1 hidden.

Its an ERJ probably either American Eagle or DL connection since it is in the Bay Area vincinity

Although this is in fact correct, their "unofficial" name is actually 'head splitters' (one of the main - if not the only- reason NOT to walk under them

Certainly an ERJ.

But this message is too short to be of any value to the aviation world, of which clearly my answer is a very small, insignificant portion. So instead, I'll just stand on a soapbox, and make my message say two things at once.

Definitely an ERJ-135/145. My best guess would be a -135. You can tell by the Vortilons as EMBQA mentioned.

They are vortilon's and fix an aerodynamic design problem.
In this case they are most likely there to prevent outboard wing stall in flaps down configurations.
Outboard wing stall is generally bad for swept wings since it provides a nose up pitching nose.

See.... http://www.berkut13.com/berkut45.htm

At high angles of attack they produce a vortex which travels over the wing which delay the stall. (Similarly to the nacelle vortex generators)

Think your confusing the ones in the picture with boat Fairings on the trailing edge flaps. These boat fairings, ,as you indeed are correct in saying, contain the flap carriages and machinery/jack screws for the flaps in order to allow them extend and retract.

I believe the correct term is "flap actuator housings", but they are often referred to as "canoes". I never heard "boats" before, but I haven't heard everything! Makes as much sense as canoes.

As for the vortilons...yeah, you do NOT want to be on the receiving end of one of those!

They are for the option to carry AIM-9 Sidewinder, heat-seeking, short-range, air-to-air missiles.

No seriously, I believe they create artificial vortices for the aerlerons, to improve their performance.

Hmm..Boeing must refere to them as Flap Actuator Housings....the correct term Airbus use in the Maintenance Manual and I.P.C. is Flap Track Fairings....but as you know yourself, its usually the shorter names we call things instead. I have heard the American guys call them canoes in the past alright, this side of the pond they are just referred to as boat fairings.

Because of the angle of the picture, I originally thought I was looking at the BACK of the wing, not the Leading Edge! My answer was going to be flap track fairings, but this is obvously wrong...

I just spoke with a 737 mechanic who I know pretty well, and he tells me that Boeing just calls them "flap housings". I don't know where I got the "actuator" part of that...must have heard it around somewhere. (Maybe from Embraer mechanics?)

Like you said though...in daily use we call them canoes, or boats in your case!
