Not Flying with Others

Not Flying with Others

Other pilots are more valuable than cu's.

Most if not all of the pilots are up around 4,100' just before the start window opens.  The gaggles have been pretty unpleasant and it is good that we are ready to get away from each other quickly.

 I notice a few pilots start , tell Larry it's time to go, and when we look back the whole field is following as we head north toward the Florida Turnpike.

There are no nearby cumulus clouds so we are heading off into the blue and flying by feel (and using other pilots as markers).  Larry, staying away from other pilots, calls 250 fpm a little to our west and a few of us deviate over to get under him, then take off to the north northeast to join back with the main gaggle, but still not climbing back to 4,000'.  Larry stays heading north over highway 33 to avoid the gaggle which is to the east of the highway.

I head off when we get back to 3,900', which seems to be the top of the inversion as forecast, just a little to the west of John Simon and slightly below him.  Larry says that he's going right up highway 33 which would give him the least distance to the 3 km turnpoint.  John is on a heading (followed behind me by almost everyone else) to go a slightly longer distance to get the turnpoint, and he does his, as he tells me later, because he feels that he is on a good lift line.  I'm right near him and yes the line feels just fine.  I'm getting 12.3 to 1 going downwind.

I head a slight bit to the north northwest to get the turnpoint above the highway and Larry points out our first cu, just off to the southwest.  This means that we will leave the other pilots behind if they don't follow us, which is likely as they have been shading easterly and now we are heading southwest.  I think Larry is happy to leave the gaggle behind.

I find the thermal under the cu and climb at 270 fpm to 3,800' with Larry.  Meanwhile John and others are behind us finding 350 fpm.

I head south and we get down to 1,800' before I find the next thermal and climb first at 200 fpm average then 340 fpm to 5,700' while being pushed back by the 8 mph southeast wind.  Given this climb we feel that we are doing great especially as we don't see any cu's forming to our east where the other pilots would be (or so we think).  They actually start flying the cu's at Grass Roots airfield.

We are able to climb at 380 fpm north of the nursery and are heading south southeast to get more in line with the course line.  We are hitting cu after cu and finding strong lift up to an average of 450 fpm.

We go to cu's over the mine to the southeast north of highway 474.  We have zig zagged quite a bit.  Now we are aware that our strategy has failed to put us in the lead as we hear on the radio from people following the competition back at Wilotree Park.

Another run to the southwest to clouds and I find weak lift but Larry is able to climb out to 6,300'.  After a thousand foot gain I leave at 3,800' and head south southeast toward the 3 km turnpoint cylinder.  I'm soon low over the trees at 1,000' with a limited set of landing option.

Down to 1,000' I'm looking at a field to my east that seems big enough and allows for easy retrieval unlike the other bigger fields to my north.  I'm still searching for lift but it looks hopeless.  By luck I happen to hit the edge of the turnpoint cylinder just as I find some lift.  Since the wind would be pushing me at 10 mph to the north northwest I was very happy to have nicked the turnpoint just as I started to thermal.

I was not going to let go of this 240 fpm thermal and rode it to 5,900' as a cu formed over me.

I've got enough altitude to make it back to Wilotree Park, at 13:1 with a tail wind, but find even more lift as I head north.  I'm west of Seminole Glider Port when I leave from 5,000' and we usually assume that you can make it back if you leave from 4,000'.  With the tail wind it is easy to make it back.

The near landing scare made me cautious on the final leg, but it was great to get back in.

The Sky Wants Us to Return

The Sky Wants Us to Return

The forecast was an utter failure

We were confronted with a forecast that said we were going to get to only 3,000' and have really light lift.  None of that was true but it made life difficult for the task committee.  None the less with Larry Bunner's guidance we called a great task that took advantage of the superb conditions and got most of us back to Wilotree Park.

Now we have to be concerned about why the forecast was so wrong and how to deal with the fact that the forecast for Tuesday is similar.  Likely we'll just grab another forecast from our set of models and also go with whatever Skew-T brews up for us.

Given our great uncertainty about the forecast we called for an elapsed task with no leading or arrival points.  We were concerned that it would be difficult for pilots to hang around for an hour in poor conditions.  As it turned out there was no reason for that.

I was about the third pilot to get hauled up as a few pilots in front of me backed out and went to the end.  Phill Bloom was first off and I was hauled up right under him.  We climbed right to cloud base at 4,100' and then sampled nearby clouds wondering who would go first.  Raul left early.

Larry and I left a gaggle of about half a dozen of the top pilots to go to the next cloud just outside the start cylinder and got up back to cloud base.  When they came to join us in the lift we headed back and got a later start time by about three minutes.  We then caught back up with them.

The task was a bit complex:

There were cu's around and we just hopped from cu to cu, which is why we didn't follow straight along the course lines:

There was plenty of lift under most of the cu's and at one point it averaged 500 fpm for 3,500'.

We have crushed the drought

It's hard to believe that it will only be from one to two inches of rain today (Sunday).

We have not had anything like this in the five months that Belinda and I have been here:

Those folks staying in tents will be most unhappy.  Looks like a warm day tomorrow, sunny, with a north wind.

A Spanner in the Works

A Spanner in the Works

There to tighten the nut on the Blade's arm.

I was waiting for the tug to come back and pull me up after it took up Larry Bunner and decided to pull out the little 10 mm wrench that I had stowed away in my harness attached to an older thin bridle line.  I started to pull it out and it just wouldn't move.  I took off my harness and followed the line around in the harness to see where the wrench was.

I was pretty amazed to find that it had traveled on a rather long circuitous journey and was now up and through the slot in my slider on the back plate.  It was difficult to even dislodge it so it was hard to imagine how it got half way through the slot to begin with.  I took the wrench and its lanyard out of the harness and put them away in a safe spot so that that wouldn't happen again.

As I thought about it something occurred to me.  Recently I've been having difficulty grabbing the right down tube.  I then realized that I've not been rocked up as usual and was reaching for the downtube too low.  I began to see that the wrench would have kept me from rocking all the way up and I just hadn't noticed.  I've taken out two down tubes because I had trouble getting my hand on and up the right down tube.

Since that discovery I've had two landings without this being an issue.  I've rocked up earlier and went back to my old favorite "monkey bar" landings.

Under the shade and over the shadow

Under the shade and over the shadow

Still the upper level clouds that came in on Thursday

We watched the satellite and the sky to see what the upper level clouds to our north would do.

https://www.star.nesdis.noaa.gov/GOES/conus_band.php?sat=G16&band=GEOCOLOR&length=24

And the band of clouds just to our north continued all day and then some.  They also slowly crept south until half the sky at Wilotree was covered with upper level clouds and half was blue with lots of cu's.

But, there were plenty of cu's under the high level clouds to our north and Larry and I decided to give the task to the north a try.

Quest 3 km
Panoak 3 km
Barron 3 km
Quest 400 m

80 km

There were plenty of cu's to head for despite the shading on the ground and we just followed our plan of heading for the nearest cu that was sort of in the direction of the first turnpoint at Lake Panosoffkee.  We would get near cloud base under cu's that were barely there and then leave when the lift slowed down.  We were getting over 5,000' easily.

We left a cu together just south of the prisons at 5,300' and headed northwest more toward the turnpoint as we were quite a bit north of the course line and the turnpoint was west northwest of us.  Larry headed further north for a fire but I held back thinking that it looked too weak to me.  I should have radioed Larry that I wasn't convinced that heading for the fire was a good idea and had slowed down and shaded to the west a bit.

Heading west I found I was sinking at about 200 fpm and later saw that I was getting an L/D of 22:1.  Larry was sinking quickly to my north as he turned west after not finding any lift at the fire.

I found some light lift when I got over highway 301 and radioed Larry.  After a while he was able to find 200+ fpm in that area.  I headed west from 4,800' when the lift gave out and didn't find anything until I was down to 2,400' and at the edge of the turnpoint cylinder.

That thermal turned into almost 300 fpm and I was drifting north in a 9 mph south wind.  Larry had climbed to 5,300' back near 301 and then came to the turnpoint cylinder edge at 4,000'.  I was well inside the cylinder and he chased after my thermal but never found it and had to head south to find more lift.

I left the thermal at 5,500' and started heading east but there were no cu's ahead so I turned south.  Larry soon landed as I searched for lift and found little.  It wasn't long before I was down to 1,500' and looking at landing options.

I found 70 fpm and stayed in the area near I75 for twenty minutes climbing a thousand feet going up and down a few times.  There was some blue sky to the south and some cu's ahead and I finally left to get under them.  They didn't work and I was soon on the ground next to I75 on the west side of Bushnell.

The Curl in the Weather for Thursday

The Curl in the weather for Thursday

The forecast didn't prepare us for the cu's

Here was the morning update of the weather forecast for Wilotree Park on Thursday:

HRRR 3:

11 AM:

South surface wind at 11 AM: 4 mph

TOL at 11 AM: 4,600'

Updraft Velocity at 11 AM: 540 fpm

CB at 11 AM: 0' Skew-T says cu's at 11 AM.

B/S at 11 AM: 10

Cloud cover at 11 AM: 1%

1 PM:

South surface wind at 1 PM: 5 mph, 2000' 5 mph, 4000' 6 mph

TOL at 1 PM: 6,400'

Updraft Velocity at 1 pm: 660 fpm

CB at 1 PM: 0' (Skew-T still shows a thin layer of cu's)

B/S at 1 PM: 10.0

Cloud cover at 1 PM:1%

Temperature at TOL: again 51 degrees

6 PM: (RAP)

TOL: 6,900'

Updraft velocity: 580 fpm

CB: 0'

B/S: 5.1

First of all the cu's started at 11 AM and they soon filled the sky.  It looked completely soarable and taskable, but a few of us were taking a recovery day.  As we know the models are very poor at predicting cu's.

As the afternoon progressed this happened:

All the cu's under the higher clouds finally disappeared.  That put those on the ground going west on the ground at 2:30 PM.

Lake Wales Both Ways

Lake Wales Both Ways

This would usually be a one way task in a competition

Larry and I do it together again without any one else coming with us.

Here's the weather and the task:

Unlike the forecast there were plenty of cu's, they just started 45 minutes later (11:15 AM) on Tuesday compared to Monday.  Also it continued to be a great day all day.

NWS:

Wednesday

Sunny, with a high near 86.  Calm wind becoming south around 5 mph.

Hourly in the afternoon: South southeast surface wind 2 - 3 mph, 11% cloud cover

HRRR 3:

11 AM:

South southwest surface wind at 11 AM: 2 mph

TOL at 11 AM: 5,200'

Updraft Velocity at 11 AM: 480 fpm

CB at 11 AM: 0' Skew-T says cu's at 11 AM.

B/S at 11 AM: 10.0

Cloud cover at 11 AM: 10 0% (not likely)

1 PM:

South southeast surface wind at 1 PM: 3 mph, 2000' 5 mph, 4000' 5 mph, 6000' 4 mph

TOL at 1 PM: 7,900'

Updraft Velocity at 1 pm: 660 fpm

CB at 1 PM: 0' (dry layer above)

B/S at 1 PM: 10.0

Cloud cover at 1 PM:7%

Temperature at TOL: again 45 degrees (dress warmly)

6 PM: (RAP)

TOL: 8,500'

Updraft velocity: 660 fpm

CB: 7,380'

B/S: 10.0

Convergence right up the middle of the state at 6 PM. Started at 3 PM.

Early launch task:

Quest 3 km
Lake Wales 3 km
Grass Roots 3 km
Quest 400 m

161.4 km

Land at Quest on the way north if desired.  Subtract 19 km.

Shorter version:

Lake Wales 20 km

118 km

Skew-T and HRRR both indicate that there won't be any clouds.  But RAP shows them and it did the same on Tuesday so I go with RAP. It looks like they would be just at the TOL.

At 11:15 the cu's show up, just a few, of course, at first but a few more later, although not filling the sky.  We get ready to launch about noon, but then have to get pulled down to the south as the wind, light as it is, is still out of the north.  The wind will be switching all day at Wilotree Park.

At 12:20 AM when I launch just behind Larry the cu's have almost all disappeared.  There are none nearby.  The ones in the distance that we can see are very thin,.  There is a dry layer of air above the inversion.  I'm concerned that we have bitten off more than we can chew.

I get pulled up and over Larry who is turning in light to no lift southwest of the park.  I join him in the weak lift as that is all there is in the neighborhood.  We continue to work it as it improves and after a while we are averaging 340 fpm and climb to 6,500'.  Not a bad start for the day that didn't look promising.

While it is nothing like the previous three days there are a few cu's around and we just start working them like we have the previous ones when they filled the sky and were as thick as you would like.  We jump from one to the next heading south (and southwest and southeast) toward theLake Wales airfield.

I'm down to 3,600' west of Wallaby but working a little lift.  Larry finds better lift a bit further south.  I come in under him and start climbing when I notice a sailplane circling a short distance away to the southeast.  I shout out to Larry and head for the plane.  The lift averages 550 fpm to 6,800'.  I'll have to be careful going south as the airspace east of highway 27 has a 6,000' bottom.

Fortunately, the west edges of the cu's going south are just over the western edge of the airspace so I can climb above 6,000'.  Larry is quite a bit lower so he can go under the airspace.

We head off to the west to a nice looking cu and get over the eastern edge of Winter Haven.  I find a little bit of lift over a housing development and then move further southwest feeling stronger lift in that direction and tell Larry who is low to come over with me.  We find super strong lift with Larry hitting 1,100 fpm.  I'm averaging 800 to 900 fpm and really disliking the lift with a couple of wire slaps.  Larry says that there is a fire beneath, but I can't see it.  That would explain why the lift is rough.  I leave at 6,700'.

I glide for 9 km coming in next to a rail yard.  at 3,500' northwest of the Lake Wales airfield.  Larry finds some lift back a ways and I join him and we eventually climb to 7000' under a nearby cu.

We quickly glide to the turnpoint at Lake Wales.  It has taken us 3:20 to get there.  A bit of headwind played a part in that.

It's very fast as we head north up highway 27 (south of the airspace) and Larry finds another super strong thermal where he sees 1,100 fpm.  It averages 600+ fpm and I see lots of 800+ fpm on the 20 second averager.  We leave at 7,300'.

There are a scattering of cu's ahead to the north northwest and we average between 300 and 400 fpm under them.  We have to search around under each cu and not settle for 150 fpm when we first encounter the lift.  We know that there is better lift somewhere else.

We climb to 5,600' at 474 and it's 9 to 1 to goal.  I head out and then find weak lift 7 KM for a few extra turns.  Larry is planning to land with me but as we get into goal he finds a flock of birds rising up from the south end of the field and goes up with them so that he can fly the extra bit to make it 100 miles.

It takes an hour and forty minutes to come back after requiring three hours and twenty minutes to get down to Lake Wales, a five hour flight.  Larry has completed four 100 mile flights in four days.

Early launch task:

Quest 3 km
Suzane 1 km
Quest 400 m

136.4 km

Larry will add a little bit at the end to extend it to 100 miles (160 km).

The cu's begin to show up at 11:15 AM, forty five minutes later than on Monday.  I launch at 12:03 right after Larry.  Larry gets towed a lot higher while I pin off in lift.  It takes a few minutes to catch up with him and at 12:17 AM we are together at cloud base, 5,600', after an average rate of climb at 600 fpm.

There are plenty of cu's ahead to the south and we just go southeast or southwest to the darkest looking cu going half way between highway 33 and highway 27.  I don't get below 3,500'.  Our approach is that we can go a lot faster if we find the strongest lift, so we go to the cu's that look like they will produce the strongest lift.  We glide only when we get near or at cloud base if the lift continues up to cloud base.

Larry gets low west of Davenport and we split up as he heads west to get under another cu and I head east for other cu's.  Communicating on the radio we hook up again west of Haines City.

We have a good view of the possible LZ'a down below as we are often over 5,000' and up to 5,900' just below the airspace at 6,000'.  There are plenty of LZ's, so this is a safe route.

After nabbing the turnpoint at Chalet Suzanne we head west to a monster looking cu.  It produces and we climb at an average of 700 fpm with bits of 900 fpm on the 20 second averager to 6,500' west of airspace.

We head north just on the east side of Winter Haven again choosing the route based on where the best looking cu's are.  I pass just east of a small one feeling a little bit of lift but looking ahead to the next cu.  Larry reports 400 fpm half a kilometer behind me and I turn around to join him under the cloud I was by passing.

We hit one thermal after another and then I lose track of Larry north of I4.  This time he got higher but again the radio helps and we get back together around Dean Still west of Wallaby.

We are side by side heading for highway 474 and a good look cu when I find 360 fpm at 5,000' and Larry is just a few feet to my west but misses it.  I radio him that it's 200 fpm (he hears 100 fpm) I then radio 300, 400 and 500 fpm.  He has already dropped a couple of thousand feet below me.  He says later that he should have turned immediately when I reported lift.

I climb to 6,900' and with Wilotree Park to the north at a 9:1 glide ratio and Larry still way below I head out ready to report any lift I find.  Larry has a plan to not stop at Wilotree but to go north far enough to make his third 100 mile flight in three days.  I'm more then happy to stop.

Larry makes his goal after going to the north and coming back to Wilotree.  For me a little bit over a 4 hour task.  Over 13 hours in three days.

Other pilots flew a similar task but with a 15 km cylinder around Chalet Suzanne instead of a 1 kilometer..
