video of my spin

[Nobody]

Sometime back I had to get my spin endorsement to get my CFI. My CFI did
the first one. I was entirely unprepared for what happened. I had no idea
how quickly the nose fell, the nose down attitude during the spin, and how
fast it rotated. Based on what I had read about spins, I didn't think we
were spinning. I had no idea what was happening. The only thing that
crossed my mind was structural failure. Had it happened to me while solo, I
doubt I would have recovered.

So, here's my point. Get spin training. Several months ago a friend of a
friend accidentally spun and didn't recover.

A few weeks ago I went up in a great little Super Decathalon with a CFI and
decided to take along my camera to get video of a spin. Don't worry, my CFI
friend did all the flying while I worked the camera. Follow the link below
to see the videos. Note how quickly the nose drops. It takes less than
three seconds to go from nose high to very, very nose low. I don't think
the videos really demonstrate how abrupt it is. In the plane it seems to
happen in the blink of the eye.

Please right click and download them. Otherwise you'll have to replay them
because they'll stall (no pun intended). Replaying them will just use up
the allotted bandwidth on the site I manage.

Thanks for posting.
Looks like your friend forced the entry of each spin, though.
The nose shouldn't jump up above the horizon.

Try a right hand spin with full power in a Decathalon. That is FAST.

I've spun Blanik gliders on numerous occasions. If you look sideways
during the spin exit/recovery, you'll see that in a Blanik, once the
spin is stopped you are pointed *straight* at the ground.

I never noticed that in the B-13. Do you suppose it is somehow a
product of the negative sweep?

Whoa! I will be starting my PPl soon and doing something like that
would have made me have to clean my pants afterwards!

Just looking at the video, my initial (and un-trained) reaction would
be to lower the ailerons, and apply light rudder opposite of the spin.
Is this even close to being right or would the fire department be
scraping me off of the ground?

Ailerons neutral. Opposite rudder.

Opposite rudder is good.
Opposite aileron would make it worse. Ailerons are to stay neutral

The recipe is "Hands off. Power off. Full opposite rudder." If you
are confused and/or inverted, push on the rudder pedal that offers the
more resistance.

The first spin was very noticeable that the pilot pulled the nose up
into an accellerated stall instead of holding the back pressure
constant... The second one was better... Looks like a fun time though,
made me want to jump up and go and do some akro.. Unfortunately, my
current mount, an Apache, is not allowed to do those things...

Depends on the airplane.
Read the Mueller/Beggs articles. Only two or three airplanes have been
tested and reported.

PARE

Power off.

Ailerons neutral.

Opposite Rudder.

Elevator down (upright spin only).

Don't try that in a Decathlon! You'll never stop spinning with that
formula.

Same as with a Slingsby T31b
and a Rhonlerche did the same to me once

I did an inadvertent spin as a solo student. If you've had spin
awareness training, you probably would have remembered to apply
opposite rudder eventually. Assuming you started the stall at a decent
altitude, the descent rate isn't nearly as bad as it looks out the
window. There's time. I probably went through 3 turns in the 152
before I deduced that it must be a spin. By that point, I'd figured
out that my instictive control inputs on the elevator and ailerons were
having no effect.

Since then, I've practiced spins regularly in my plane. They're a
lot more fun when you're expecting them <g>.

Doesn't stall at all on a Mac, using the Quicktime plug-in. Must be a
Windows thing. :-)

Hmmm... weird. For me, they replay from the Quicktime plug-in's cache,
not from your server, so no need to hit your bandwidth allocation.

Thanks again for the link!

Works fine on my G4 iBook with OS 10.4.1 and QuickTime 7.0.1
I even downloaded it and saved it.

[Nobody]

They were coerced to get a good spin going, not forced. :-)

I think it's reasonably realistic in that most of the time people who
accidentally stall/spin do so with the nose high. This isn't based on any
study but just anecdotal information from other CFI's.
