Combining two of my favorite things (flying and computer technology) I
took my new iPhone with me into wave and shot some video with it:



It was an amazing day. I topped out at 10,000ft and could have gone
higher, although my climb was very slow at the end. I only came back
because it looked like the clouds looked to be closing up underneath me,
and I didn't want to be trapped on top. These conditions are *extremely*
unusual for June around here. I would be pleased to get up to 10,000ft
in wave in February, but I was *astounded* to get that high in wave in
June. (For those of you not familiar with soaring weather phenomena,
wave is usually a winter thing.)

Flying in wave is really a neat thing. You can't tell from the video
because my hand isn't all that steady, but it's *perfectly* smooth.
There's literally no vibration or bumpiness, and just a little wind
noise. It's incredibly peaceful even by soaring standards. Would have
been more peaceful today if I hadn't had to worry about my hole closing
up underneath me, but so it goes.

Since this is a student group, here's a list of things I learned, or
learned better, from this flight:

- Wave strength can depend greatly on where you are, not just
forward/back (in the direction of the wind) but also side to side. My
first spot was really crappy, giving me about 25fpm average down, and I
only got into the good stuff after moving about five miles perpendicular
to the wind.

- When you're bumping against a ceiling, search for holes by looking at
the shadows on the ground, not by looking at the sky.

- If the forecast calls for wave, believe it, even if it's completely
out of season.

- When your partner says he's going to return your plane to the airport
on day X, and you plan to fly it on day X+1, you should communicate this
fact to him so that when his plans go completely wrong and he has to
keep it an extra day or two, he can tell you not to expect it to be
there.

Awesome video. Looking forward to soaring in a wave some day. Is this
the newest iPhone or an earlier JB version?

Thanks

It was a great experience, and a rare one for me. I just realized today
that in 3 years of flying gliders, this was the first time I had *ever*
flown in wave alone. All the previous times were either with an
instructor or, on one occasion, with a fellow pilot as a passenger. As
opposed to thermals or ridge, where I have long since lost count.

I took the video with a new 3GS, delivered to my door a mere two days
before that flight. I'm really impressed at the quality of the camera in
the thing. It's not all that great compared to a real camera, but for
something that's basically just a little dot on the corner of my phone,
it's really good.

Is it the angle of the camera that makes it look like the yaw string shows
some side slip? Or did you have your foot a bit heavy on the right pedal?
:-)

I assume you were tapping on the altimeter to make sure it wouldn't stick
so you'd know immediately when you hit 10k? I found myself tapping the
altimeter on our SGS 2-33 trainer when I discovered it would jump
occasionally. I did it mostly when I was trying to train myself on what
different altitudes looked like during landing and wanted an accurate
reference. Otherwise the sticky altimeter wasn't a big deal.

Funny you should ask....

Yes, the string was off to the side. However, I want to point out that
the camera exaggerates angles, so it was not as dramatic as it looks. :)

However, my feet were perfectly centered. I did some experimenting on
the way up, since the air was so unbelievably smooth and I had time to
screw around. For some reason, this particular glider actually requires
slightly off-center controls to have the string be perfectly centered.
Small but significant pressure on the left pedal, and a slight offset of
the stick to the right, was what was required to keep the string
centered and bank steady. Subtle enough that I couldn't remember to do
it consistently on the way up.

Yes, that's exactly right. Typically I'll tap the altimeter in a really
weak thermal when I want to know whether I'm getting a net climb or not,
and it's too inconsistent for the vario alone to tell me. Make a couple
of circles, tap, watch it jump 20ft. If it jumps up, I'm in good shape.
If it jumps down, need to work harder. Not strictly necessary on this
flight, but the closing gap below was looking worrisome so I wanted to
tag my goal and then hot-foot it home.

Quite a difference! That looks a lot more like the video from my old
RAZR did. It's cool that you were able to hack it, and certainly isn't
the worst cell phone camera I've seen, but the new ones really are a lot
better.
