Welcome back after a long break
Hi! Hello everyone.
Today we have for you analysis of a incident which took place on Zar.
Less than a week ago.
Wing - Cayenne
Pawel is the pilot. Greetings to him.
Well then, Pawel thrown a reserve.
Luckily there were some people
who rushed to help him
Bikers
Pawel didn't have a chance to thank them, therefore he asked us to thank them in this movie.
They were bikers who reacted very quickly to his bad fortune
As well as pilots who were at the take off, also rushed to him
Luckily nothing major happened to Pawel.
Everything is OK. It finished with happy end.
Yes that's nice that people run to help him.
because
In case of accident we often see
it takes a lot of time for someone to get to the pilot.
Which is really important
And Pawel said it several times that people were around him very quickly.
Therefore big applause for those who were helping there.
So great job Boys and Girls.
I'll rewind and we will move on to analysis.
I will pay it with sound on my side
and you can later edit it so it works.
So I'll just play it now, without narration, so everyone can see what happened.
And that's how the whole subject ends.
Nothing really happened.
I'll switch off the sound and rewind the film to about half way trough.
because the film is a bit longer.
-Jarek are you still there?
Yes Yes!
I think it's a skywalk wing.
Yes. It's Cayenne.
Cayenne is surly a sport wing.
It's not a school wing.
I don't remember what category wing is that.
But I bet its a EN C
We will check it later.
So I don't make complete idiot out of myself.
So we will try to analyse it a bit.
I'll divide it into two analysis.
The first one will be very general.
Where I will talk about what happened here
and later I'll try to go over it step by step
I hope I will succeed, cause its easier said than done.
I can hear the audio so I know the pilot is turning right in the thermic
I don't know the set up of his vario
But the bipps are quite intensive so I think the thermic is usable
the wing is braked
We can see the trailing edge being braked on the right side.
And I think the pilot is weight shifting a lot
because the horizon is tilted in the camera that is probably mounted centered on the cask .
So I would like to Notice that while turning in this thermic he weight shifts a lot.
Now is the moment...
I know we cant see the wing
but we have a air separation on right side of the wing
and in that moment
forces on brake lines change dramatically
but only on one of them
on the inside one
So the right one in this situation.
The force on this line decreases.
the wing will give us two warnings before a stall
First one: when we look at the wing
It starts to look like a hockey stick
where one of the sides falls backwards, and the whole wing starts to bend
That's the first warning - we should immediately rise the hands up
Second waning is often too late
for less experienced pilots
The control goes soft all the sudden
at first it's getting harder and harder, and at once the force on it disappears.
And that mean the air flow already separated from the wing
I believe without even looking on this wing
that if the pilot would immediately raised the right control up
The wing would gain the speed back
It would shoot forward slightly, which needs to be braked
proportionally to the amount of pitch
and he would fly normally
I don't know his altitude above those trees.
But I assume theatrically that he would regain the speed and fly over those trees
I'll play it again
Here you can see the wing being bent backwards.
We can see the airflow detached from the wing on the right side
the right control is pulled down
Pilot is still weight shifting to the right
The fame is tilted.
And we've got airflow separation on the right side.
The pilot eases on the brake, because he sensed something happened.
And it's the right reaction
If he would have stayed in this position, with his arms up
the glider would shoot forward, the wing would regain the speed. He, then, would have to brake it.
and he would continue to fly.
No biggie.
But that's not what happened.
Because here we have another pilot's input on the control.
Yet again the pilot pulled the brakes down
Why?
In my opinion
He is surprised with all that situation
and he is in a state of flight he have never experienced before
Its a strange sensation, he doesn't know what's going on with the wing - it's fully inflated
resembles snake
and it's a parachute faze
In this faze
The wing is inflated
However the forces on the controls are completely different
and even the slightest move on the brakes: 2-3-4cm has an impact on the wing's behavior
and only experienced pilots, who try to find the point of airflow separation
already completed 2-3 SIVs
play with the ACRO tricks
Are able to cope with such a state of flight
and get out of it very quickly
That's why I'm not surprised that pilot less experienced got surprised by the situation
Because to be able to handle this situation, he would have to practice such situations regularly.
So there's brake input.
The wing is in parachuting
and become to dance above his head
Notice that the wing is inflated
It's not collapsed anywhere
It's a clear evidence of parachuting.
It's not even a spin
because he doesn't change direction by 360 or even 180 degrees
Why am I saying that?
Because the glider is fully inflated
and during a spin it takes slightly different shape
One side starts to pull back
and the side which is pulling back
Has an ear at the front
in this way.
and the opposite side starts to move positively forward, and in most cases
it's not deformed.
So yet again after pulling on the brakes, he lifts his arms up
So again. It's OK. If he would keep it that way
the wing would gain speed and shoot forward
but gain here, he starts to pull down
Notice, those are not massive inputs
And now due to wing oscillation commenced earlier
that causes twist
which means pilot is spinning slower than the wing
That's why he gets 180 degree twist
and in this faze here
because he pulls on the left brake
as well as on the right
being twisted he goes into a faze of flight which calls backwards flying
and I can clearly recognise that
because the whole wing is inflated
and only the tips of the wing
are tucked in
there's still way out from this position
by smoothly easing up on the brakes
but we have to be prepared for the wing shooting forward
and to be able to stop it
The pilot doesn't pull the brakes deeper
but if he would, he would go deeper in this stall
and in a half stall he would reach those trees in no time
But that's not what happens
because he's flying backwards
and sink rate is not as large as in deep stall
when the brakes are buried under a harness
so now here he's doing the right thing trying to untwist himself
He reacts accordingly
and all this time he 's pulling on the brakes
That's why everything is stalled.
And now because he's low, he takes a decision to
He stops to deal with all that
and begins to look for the reserve handle
Maybe it's a right decision
And I think Jarek will agree with me
Yes.
If in doubt, and the situation is too much
throw the reserve
especially if we are in such a critical situation
Would you agree with me Jarek??
Yes, Yes of course, considering he was really low
We could see he tried 3 times to solve the situation
We could see they weren.t the right reactions, for the most part
beside we have to keep in mind it all happens in split of second
It's a quick brain storm
And I think he was so low he decided to throw the reserve
and I suspect that after those 3 attempts
it was the smartest solution
He could have make a few more mistakes
and run out of altitude
Exactly. I would like to emphasize
that it's easy for me to comment
"here he pulled 3,5mm to much.."
"and here he didn't pull enough..."
"And there he could have pull his legs around his neck"
"that would improve everything"
But that's not the idea of this program
I would like to tell you what I see here trough my experience
Because everyone can see different things
I'm only saying what I can see
in given moment
and I can recognize those states quite well
here he stopped dealing with it
and look here! can you see that?!
Haw far forward does the wing shoot!
Why? Because he let go off the brakes.
Yes, Yes.
He let go off the brakes.
and this is dangerous situation
If we are in to moment of airflow separating from the wing
On the one side of the wing, or both
and we have arms up
we should be prepared for the wing shooting forward
and we have to brake that
because that oscillation induced earlier,
after a few failed attempts to solve it,
will be that large
we can find ourselves in a situation where the wing shoots forward so much we end up falling into it
and in this case, with this height above the trees
wrapping yourself in a wing, means the end.
So pay attention
if someone tells you - hands up
and the wing is certificated
in its class
and it wont shoot forward so much, cause it was certificated
This is not true.
Because, some situations took place earlier, which have never been tested
We have to really pay attention
Because that forward shooting,
after a spin
Could be really large
we might not have even enough time to throw the reserve.
because we are already wrapped up in the wing
but luckily that's not the case here
The wing shoots quite a bit, at least that's how it looks like
Now we cant see what happened to the wing
but I bet, that in 99% he got large front stall
Here he throws the reserve
excuse me
and what can we see?
looks like he's throwing it up
I think he did throw it up after all
and I think he should have throw it as far backwards as possible
So I think that's also a mistake
But I don't know how would i act in this situation
cause there was some adrenaline rush, he needed to quickly use that reserve
above those trees, and that's what he has done.
can you see how far up is this reserve going?
It should have gone backwards
but it's going up above the pilot
Oh and now you can see I was talking bout front stall
and here we can see this front collapse
Now it's re-inflating
Front tuck is opening, so does the reserve
and the Pilot
here we can see he still tries, he has good intentions
he tries to roll up the wing
but quickly realises he's so low it doesn't make sense to even bother
and he should rather try to catch some branches
he tries to brace during the impact. And I think he landed quite soft. I think so - I'm not sure.
You still there?
Yes Yes
I will rewind it, and we will make quick review
yes I would like to add something
Go On.
I just would like to add that the pilot
did everything by the book
because
Ok maybe he didn't do everything right regarding getting out of this mess
but he tried to fight
it went tits up
he analysed the height
and he decided to throw the reserve
I think those 3 factors that he performed are school example
we can see he is experienced pilot
because as I said, we have the attempt to fight,
we have the quick altitude analysis
and thrown reserve
I think if he would be 400-500m higher
He would carry on fighting
Exactly
The question is
Is it worth to fight till the bitter end?
because sometimes we might run out of height.
We can see when the reserve opened.
And we can see it was the last moment
Yes, That's why I always emphasize
that in the situation where we don't know what to do, we should try to use that reserve.
and that's what happened here
Luckily nothing bad happened
Glider doesn't dive too much after the separation of the air flow
so he only gets a frontal
then he opened the reserve
and landed on the trees
Just a quick recap
So at this point the air flow separates from the wing
the pilot should have lift his arms up
So the wing would dive, but it wouldn't be a dramatic one
Because the airflow didn't separate entirely form the wing yet
In my opinion it would be sufficient to just, at his moment
maybe not now...
And now it starts to go back, because the wing disappeared from the view
At that point, when the brake line goes soft
and the wing starts to looks like a hockey stick
One should lift arms up, and wait for the wing to dive
then brake, asymmetrically, or metrically
and he would continue to fly
The air flow separates from the wing.
the wing is in parachuting
the inputs on the brakes are unfortunately incorrect.
They are not applied accordingly to the situation
because its all happening very fast
Now the pilot decides to use the reserve
Reserve out
and the reserve inflates. It actually inflated very quickly
Almost instantly. Shame we cant see that.
I estimate it inflated in about 1,5s.
Because he threw it upwards.
I'm not so sure abut that..
The rule of thumb is that we try to throw the reserve, as far, outside the layout - Pilot - wing, as possible
It normally takes place in rotation
It's more important there.
As far as possible away from yourself
It was ok. I'm not gonna be nosy here.
It's all good.
and that would be all from me.
I was trying to explain what i see here.
Maybe others will see something else
But I think I got quite deep into states of flight we could observe here
So that would be all from me. I don't know if Jarek want's to add something
No way, I have nothing to say here.
I just wanted to point out...
It's worth to mention and appreciate that he did throw the reserve in just the right moment
and that was the very last moment to do so
After 3 mistakes he could have made more of them
Which could have cost him life
So I think the response of the pilot
to unsuccessful try of regaining the control of the flight
He made a decision to throw the reserve
I think it was a good decision
And when I was reading the comments like "he still could have get out of it"
Yes he could have...
but look how close those trees are
He was really low. It's also worth to mention
Zar is a very moody mountain
and there are some places
where it might bite you in the @#?
And that's it folks.
I just remembered something.
This kind of thing
...air flow separating on one side of the wing
You can practise during SIV, over the water
and practising that during SIV
enables you to
get to know the feeling of it, in controlled, safe conditions
and allows to learn the reactions, which it thermic wont be random anymore
but they will be the right ones
In my opinion
the theory of physics
Why is it flying, why is it not flying
when does the air flow separate from the wing etc.
It's completely different from the practise...
If we wont practise it, the theory wont help us a bit.
This theoretical knowledge that this air flow might separate from the wing
That's my opinion. That's why I encourage you to
practicing all of those weird states of flight
during some cool SIV training
That's all from me.
Thank you all very much for sticking with us till the very end
Soon we will release another episode
We will try to make it ASAP
Maybe one day we will be bale to make
episodes systematically
If not...
hey, what can we do...;)
Thank you all very much
all the best.
C ya! Bye
