Poor judgment and launch technique : Sat27Feb High Rock

Post by markc »

I had a lousy/scary launch at High Rock on Saturday. The how-and-why
are pretty clear-cut; but the process might be of some interest to
others, so I thought I'd provide some details.

Conditions at High Rock (Sat28Feb) had picked up by about 1:00 due
to a frontal passage. Definitely rock-and-roll... the early wave of
pilots had landed because conditions were getting strong and the fun
factor was low. Up top, we (Spark, Carlos, myself) were seeing 15-20,
with gusts to 25+; clearly not flyable. I ran a shuttle with Carlos,
and then the waiting around began. An all-too-familar pattern lately,
eh? :roll:

Conditions were forecast to start backing off after 2:00. At 3:00,
I started to see some 12-15mph lulls that were tempting. Based on clouds
and birds, I figured that the flying itself would probably be pretty
fun, I just needed to get off safely.

(And this turned out to be true, at least on my U2. I got about 2 hours,
no penetration problems, 1300' over a few times, a great flight!)

But the strong cycles were still gusting to 20+ and the direction
was sometimes significantly cross-left: good judgement and
technique would be required. I watched a few more of the lulls, and
finally geared up around 3:30 with a definite picture of exactly what
I wanted: a lull on the pine trees to the left and right; no gusts
visible/audible; enough time to get out to the edge; enough time to
pick the glider up and get balanced.

But that's not what happened. I launched unbalanced with a lifted
left wing, and had one of those can't-believe-he-got-away-with-it
launches, with my right wingtip clearing the pillar and/or tree by maybe
a couple of feet.

Given that I knew the challenges I was facing, how did I let this come
to pass? *This* is the interesting part....

Two things come to mind:

- the inherent stress/anxiety of launching in those conditions
- a desire to fly that compromised my safety-conscious decisions
made minutes before

It was strong. The primary wire crew were roped in; they were
both backed up by someone holding onto them, and I had a keel assist.
We waited out gusts at the back of the cube. Then slid forward during
a likely lull; I would try to pick up, but no go; so back off and wait.
We did this twice. On the third try, even though the lull was not
the 12-15 I was looking for, I chose to go. And on that third trip
out, I did not have my right wing forward, as conditions demanded.

I think that I simply *forgot* to do this, given everything else
that was going on (watching/listening/wire-crew feedback/trying
to balance the glider/trying to get to the edge). That's just LAME!

Adding to this was my desire to "make something happen". I've been out
there a lot lately: cold crappy weather without much of a pay-off in
terms of airtime. So there I was, willing to launch in winds that were
not comparable to the halfway-decent cycles which had gotten me up
there in the first place! Geez, am I really that air-horny??? I guess so....

I'm not going to say that I will never try to launch in similar
conditions in the future. So, what change in behavior might help
prevent me from the failures of technique and judgement of this launch?

One idea (Spark's) is to set a limit on the amount of time that I'm
willing to hang out on launch. If I can't launch in 10/15/whatever
minutes, back off of the cube, unhook/climb-out, and "reset" for another
try after re-examining conditions.

Another idea (mine) is to try to 'break the ice' somehow. You've
gotten out there, had to pull back because things weren't working...

Ok, so come up with the mental equivalent of backing off of launch,
sort of a 'time-out' on the stresses of the situation. If you've got
a wire crew that's willing to hang out for a bit and continue giving
you a hand, well... tell 'em that you're just going to sit and watch
things for a while. Chill out! Tell a joke! I know it sounds trite, but...
RELAX!

Many thanks to Spark, Carlos, Danny, and Wesley (and whoever I'm
forgetting) for helping me launch. For all the new pilots who were
there : I hope this gives you some insight into my thought process,
but remember, your choices must always be your own. Think about what
the day was like, talk to other pilots, talk to your observer, think
of the types of conditions you've launched in... and let it all sink in!

Mark,
Sure glad you made it. I was trying to think what other things I could have done to ease the launch, the one that comes to mind is better coordination with the other wing. I have seen you launch in challenging
conditions many times so at no time I thought this was pushing anything,
but I agree all of us had to be aware when we are in launch mode too long.
I had seen wings drop in lighter conditions earlier. In one case
the pilot clear and the wings were neutral, but as soon as got the wing in the air, on the last step off the rock it was unbalanced.
After all you got a well deserved good flight (We forgot to put in your harness the brick you earned) . I saw you doing 360s with ease, leading me to believe the conditions aloft were pleasant.
I waited some more thinking launch conditions had calm down, after all the excitment I wanted a brain dead launch. I got to the bottom of the rock and heard more wind action, decided to check the rock. It wasn't the brain death condition that I was looking for, so I backed off packed up and went home.

Guess I'm pretty far removed from all this and my opinion's not worth much anymore but I've got a big mouth so what the heck.

Seems to me the dividing line for whether or not to fly might be how difficult it is to get launched and how much time it takes. Granted, there are times when a thermal is coming through and you'll need to wait for it to go back to the "launchable air"that was there before but if you're getting thrashed around up there for quite a while and can't launch, maybe you should break down before you just think "What the Hell" and yell clear anyway.

Sounds like your launch was similar to but not quite as screwed as Ellis' a couple years back. I was there and she is VERY lucky to still be with us. You can talk about technique all you want but the bottom line is that the strong conditions can ALWAYS kick your ass no matter how good you are.

Reward vs Cost guys!

There was never any "what the hell" mindset on my part.
And I hope there never will be.

What there *was* was : a) erosion of my initial decision about what
velocity I was willing to launch in; and b) poor launch technique during
the resulting too-strong cycle that I ended up taking .

On strong days, sometimes you *do* have to wait out conditions
for an acceptable launch window. And it can be way longer
than just sitting through some thermal cycles. I've been in that position
many a time at both the Pulpit and High Rock. Early on, some of my
resulting flights were more interesting than fun. But I've gained some
experience since then, and when I choose to fly on a strong day I
don't usually regret it.

To my mind, what's interesting is the process by which one can end
up compromising on a decision about 'acceptable' launch conditions
(whatever those conditions may be, given your level of experience).

That process can happen in lots of ways; I mentioned the two that I
think were most relevant for my launch in my initial post.

A little more patience, a more relaxed attitude, less craving for airtime,
and (hopefully) improved launch technique as a result.... and I suspect I
would have had a much better launch.

Or, I would have eventually backed off after getting bored :wink:

Hey Mark

I didn?t think the wind was too strong at the point of your launch. While it wasn?t the lightest cycle, it wasn?t too bad. I think the majority of the problem stemmed from the left wing being high when you launched. That immediately rolled you to the right with an ensuing slip. It was a little scary, but I?ve seen worse. I think it?s imperative to launch with wings level; a yaw is acceptable but level wings are really important. It is also imperative that we clear the pillars of spectators. What happened to you could happen to anyone in any condition, not only gusty and strong.

I don?t remember seeing a streamer on your flying wire. In gusty conditions, that streamer sure provides insight as to what the air just in front of the glider is doing. It?s a very reassuring piece of thread (at least for me.)

Introspection and analysis is very important and the hallmark of a safety-oriented pilot. You should be applauded for sharing your insights for this experience. Too many people are delusional about such events and simply blame their mishaps on conditions. Don?t kick yourself too much. You got spanked a little? chalk it up to experience.

You sure looked good up there plastered against that impossibly blue sky!

I think a lot of the launch incidents in moderate to strong winds can be avoided by getting your butt out there. On the edge. If you have a lot of pressure on one wing, move the other one out until you have pressure there also. I see a lot of people move the lifting wing back to balance the wing. That appears to work. The wing is balanced. But when you take a step forward one of the wings will inevitably hit the airflow first and -- instant wingover. If you are all the way out there with both wings in the airflow and lifting I think it is tough to have a really bad launch.

I think there's a tendency to become acclimated to conditions when sitting
in strong winds for a long time, then misjudge them. windmeters help keep
the calibration from drifting.

No worries there! I may be analyzing it into the ground... but actually,
I'd kinda like to have another 15-20 day up at the Rock ASAP,
to see what effect some attitude changes on my part might have.
Bring it on!! :)

On nose streamers: I don't have one because I figure I should be able
to determine what the air's doing in the immediate area just by the feel
of the wing, and streamers out in front/off to the side should tell
me what's going on further off. But maybe I'll reconsider that...
