What are those pointy things hanging from the flaps called? And what do
they do exactly?

As far as I know, they are just fairings for the flap extension/retraction
mechanism.

If they are called anything other than "fairings", I don't know what.

The fairings that cover the flap tracks are sometimes called "canoes"
due to their general appearance.

I saw a display of the Airbus A-380 "canoes" once, they were *massive*.

On the B727, these would be called "Flap Actuator Jackscrew Fairings"
You can actually dispatch with these missing, after consulting the book.
(Reduction of Field Length Limit and Approach/Landing Climb limit of 100 lbs
is necessary, according to my manual)

Ah, I see. I didn't realize how much the flap track/hinge protruded
underneath.

It seems to me that the canoe-style fairings were not implemented until
maybe 15 years ago, because I don't remember seeing them before 15
years ago. Did the fairings used to be small and hidden below the flap?
And then evolved into extending well beyond the flap?

On my plane, the pointy things hanging from the flaps are called
"icicles."

.... but not this month.

Right. The flap actuating mechanism is very complex, and large. It allows
the flaps to actuate back, and at a downward angle, with slots between each
section of the flaps. This allows the wing to grow in size (with the flaps
extended), and increase the lift coefficient of the wing with the flap
extended, more than just a plain pivoting flap like general aviation planes
usually have.

LoPresti Speed Merchants out of Vero Beach Fl frefer to them as
"splitters". which are fairings that cover both the forward and aft flap
hinge assemblies for GA applications.
