Dartmoor Gliding News - Wednesday 2 July 2025

As an instructor, flight planning should start when leaving the house in the morning.  A front went through during the night, and with the open bedroom windows, it was evidently windy and gusty.  Gustiness was the warning from the forecasts.  As I got into my car, the lime tree in the front garden was still, then the branches thrashed about, and then it was still again.  The hedges by Brentor church were doing the same.  So, although I waited for Mike Jardine, the Duty Instructor, to arrive and confirm my assessment, I was planning to cancel our visitors today.  Added to the concern was that in some of the models displayed in the "Windy" App that the north-westerly might veer to the north and provide a full cross and gusty wind across the runway.  That wouldn't be pleasant.

Reluctantly, following confirmation from the Duty Instructor, I cancelled the visitors (a One Day Course and three sets of trial flights) and told them how to rebook 

After a short morning brief, the flying commenced promptly at 1021.  We left the Puchacz but took the two K-13 and, in case the forecasts were overly pessimistic, the K-8 to the east end.

Mike Bennett drove the winch for the first launch until I had finished some Fleet Manager business in the clubhouse, and then I relieved him.  Laying off was the order of the day in the brisk north-westerly but remarkably, all the cables landed back on the field.

Praying for thermals perhaps? Mike Jardine and DB carry out their checks
before taking the first launch of the day.
Flying the K-13s "two-up" was the order of the day while the gusty conditions were assessed.  Yes, it was gusty.  The wind was quite strong at height, and circuits definitely needed to be upwind.  Delivering a One Day Course and the trial flights would have been a challenge.  So the Duty Instructor had made the right decision.

An already thermic sky promised much soaring as Connor soared with Mike on the second flight

The sky was looking good
With Mike soaring with Connor, Peter decided to take John Osment up, and they achieved the longest soaring flight so far, 20 minutes. 

Peter had plenty of time to photograph the airfield whilst John Osment soars CCY for 20 minutes
Alas Raymond only managed a circuit with Mike, which must have been frustrating to then see Steve Lesson soar with Peter for 27 minutes.  Then it was Freddie's turn with Mike to soar for 31 minutes.

But then Steve outclimbs Freddie when they meet in the next thermal

We welcomed our Chairman, Steve Lewis who had come to the club to watch all the fun; obviously, it was more enticing than teaching teenagers to drive (his day job). 

This is what we like to see; no gliders on the runway, all are in the air.
Freddie is now properly placed in the thermal
Steve wrings more lift out of the thermal while Freddie, below, leaves it.
The sky must have cycled because both Harvey and Mike Bennett only managed a circuit.  On a second flight, Harvey managed to soar.  Then John Smith managed a circuit.  The sky then cycled and we were back to soaring again.

Mike Bennett relieved me in the winch with Raymond as his trainee.  Raymond later remarked that perhaps it wasn't the best training day for a prospective winch driver, as the gliders were staying up and so the launch rate was quite low.  Then it was my turn to fly with Mike Jardine in FGR.

Later in the day, Alasdair and Peter admire the inviting looking cumulus clouds stretching out to Tavistock and almost to Plymouth during the longest flight of the day

The two K-13s jump across the streets while each heads for the other one!

With me flying from the back seat, Mike was able to relax and enjoy the view.  After centring in a thermal, Mike remarked that it seemed quite smooth from the front seat.  I said "look at the stick" as I was having to move it constantly and vigorously to maintain the correct pitch attitude and bank angle.  Then we hit a big gust that would have had us out of our seats if we weren't firmly strapped in.  Mike decided that not flying the trial flights was indeed the correct decision.  We enjoyed climbing to 3,000 feet and jumping between the cloud streets.  After 25 minutes, we agreed that we should limit the flight to 30 minutes and so headed away from the lift and "bang" into a 10 knotter.  I just had to take that for a few turns before starting our descent.

Gavin cranks FGR into an 8 knot thermal that briefly peaked at 10 knots.  Over the ecstatic screaming of the XK10 vario Mike remarked, "So this is the forecast four-star rating from RASP".
The cloud base eventually rose to around 4,000 feet AMSL
Mike and I landed after 35 minutes.  We had to air brake down from 3,000 feet, although at times we were climbing during our descent!  Peter and Alasdair managed 37 minutes despite Peter "locking" the airbrakes open on Alasdair in the circuit as a training exercise.  These instructors are sneaky!

The two K-13s under a booming sky.
However, the sky must have cycled again as David Archer managed a circuit and then Freddie took a hangar landing.  Despite the sky cycling, so that not all could enjoy the challenging soaring conditions, it was all good stuff.

Which way are you going to go Freddie?
Steve clocks up flight hours whilst the K-8 is walked back to the hangar.  It was that windy that we needed some weight in the K-8 for safety.  Steve, revel in being useful!

At last a meaningful use for the CFI's tyre trailer.  Bringing the broken chairs from the launch point back to the clubhouse for disposal.

Gliders parked by the fence awaiting hangar packing.  "Cracking, sky Gromit!"
This was the delay.  How many glider pilots does it take to rig a "concrete swan", sorry, I mean a Twin Astir?  Answer: Long enough to make a cup of tea in the clubhouse and drink it outside while observing the fun.

 Finally DSL heads towards the east end and back to its T-hangar after completing its Airworthiness Review Check

We finished relatively early after 14 flights; however, the 12 visitor flights weren't flown, so it wasn't a bad flight total for the Wednesday Wavers.  No visitors helped to make it a relaxing day, but it was quite hard work up there, and most had had their fill.  Although gusty, the majority of pilots managed to soar in some challenging conditions. 

"All's well that ends well."  "And not a sheep to worry us."

STOP PRESS:  On Thursday, 3 July 2025, erstwhile member and DGS Basic Instructor Richard Roberts made his third attempt at a 500km out and return flight.  The task he set was a remote start west of North Hill at Cullompton (CUL) to Sackville Flying Club (SAC) (2 NM north of Bedford) and return to Cullompton.  He was flying his Discus glider, G-CHLS, tail number V5. 

This was Skysight's forecast for the potential flight distance.  The hotter the colour, the better the conditions.

Richard's 500 km flight
The statistics:  507.9 km.  6 hours 28 minutes.  Average speed 78.5 km/h.  The flight qualifies for a FAI Diamond distance leg.

Congratulations Richard.

Dartmoor Gliding News - Monday 30 June 2025

Yes, it's a Monday, and we're blogging.  So, a word or two of explanation.  With the kind cooperation of Devon and Somerset Gliding Club (DSGC), their Eurofox, G-GNHL, will visit Brentor once a month, on a Friday, to provide aerotow services.  This will also allow DSGC members the opportunity to fly from a different hilltop site and to fly the gliders in our fleet.  DGS members can remain current on aerotow launches, receive training on aerotow launches, or utilise the opportunity to go high and conduct spin training in our Puchacz.  So, to start us off, the CFIs of the two clubs (Rick Wiles and Mark Courtney) arranged for the first Friday aerotow day to happen on a Monday.  Confusing, isn't it?

Monday dawned foggy on what was to be the hottest day of the year.  DGS members arrived and set about getting the kit out and welcoming DSGC members: David Perriman, Steve Westlake, Ashley Thomas, and Martin Woolner.  Tea and coffee were consumed.  All had previously flown at DGS.  Unfortunately, the Astir CS77 was unserviceable whilst it awaits a replacement release cable to be fitted.

A foggy start at Brentor (it was even worse at North Hill)

The Puchacz, two K-13s, and the K-8 were ranged and inspected.  Then there was some waiting.  I could see from the webcam at North Hill that the airfield was socked in with fog too, so the Eurofox wouldn't be departing anytime soon.  More tea and coffee were consumed (it's a good thing that they are free at DGS)!  This generated a relaxed atmosphere as was there was no rush.  When the weather gods allow us, we could get started quickly as we are going to operate from the west end.  The wind was forecast southerly to south westerly, but light and variable all day.

The Duty Instructor, Peter Howarth, briefs a packed clubhouse
After the morning brief, the fog started to lift.  By choosing to fly from the west end, we would christen Zack's Shack.  All seemed to work well, but the launch point to winch communications needs improvement.  With the tug unlikely to arrive soon, winch launching commenced.

Three amigos from North Hill (and Steve Lesson!)

First up was Martin Woolner, who is a Flight Instructor Coach (FIC), but he needed a site acquaint and refresher session in a K-13 with the Duty Instructor before he could start to instruct.  Viktor then took his place for a check flight in CCY before being cleared to fly CCY solo. 

Victor concentrating on checking the air brakes before taking a solo flight in CCY.  Slava Ukrani!
We welcomed back Ged Nevisky to the club.  Ged retired from gliding a while back but confessed to Scratch that he was bored at home.  So Scratch brought him up to the club to fly.  They took a winch launch in the Puchacz as a warm-up before the tug arrived.  
  
Who knew that Scratch could tell jokes?
After the dynamic duo, it was time for the only ab initio trainee, Connor, to take a pair of flights with Peter.

Peter using the opportunity to check the aerotow launch failure options when launching to the east (we are looking to the west): 1) The L-shaped field just forward of the wing tip and along the leading edge; 2) The stub runway; and in extremis 3) the south field next to the runway which lies beyond the L-shaped field.

So, where was the tug? The fog was worse at North Hill.  The pilots launched but had to land again as the fog was still solid from the M5 westwards.  Eventually, they were on their way and were spotted on Flightradar 24.
 
Hurrah! The tug arrives.  It's on the downwind leg to land on runway 290.

Mike Bennett was the first to aerotow launch with Martin in CCY so that Mike could build up his aerotow experience before being cleared for aerotow launches, probably at North Hill (or maybe another session at Dartmoor Gliding).

Then it was time for Scratch and Ged to aerotow in the Puchacz, Scratch being aerotow current from the rear seat.

Not bored now, Ged?
"All out, All out!"
Ground roll. The Puchacz is balanced on its main wheel.
"This brings back memories".  Ged enjoys the view towards Tavistock and Plymouth.
David Perriman took a solo launch in K-13, FGR, as his favourite, the Astir CS77 was unavailable.  CCY was in use by Steve Fletcher to become aerotow current flying with Steve Westlake and later with Martin.  Apparently if there had been better communication between Steve and his two instructors, he could have been signed off for aerotowing.  It's good to talk Steve!

"CCY Brentor Base. Who is P1?" "Steve." "Who is P2?" "Steve." "I thought you said Steve was P1?"

CCY and the Eurofox turn away from Mary Tavy for noise abatement reasons (although the Eurofox is very quiet with its four-bladed propeller)

Another antipodean moment, Dartmoor style.  The two Steves in CCY enjoying their flight.
Steve Lesson was next up in FGR with Martin for some aerotow experience.  But before that Andy was the first single-seater pilot to launch and claim the longest flight of 27 minutes, albeit from a 3,000-foot aerotow.

The Eurofox returns after taking Andy to 3,000 feet 
Then it was Phil's turn, and being a canny farmer, he made the compromise of being towed to 2,500 feet.

I was next in the list for an aerotow currency flight in the Puchacz.  Connor had brought his camera gear and was hankering after a flight in the Eurofox, which would normally be possible when the tug is towing a single seater.  But it was hot today.  The tug pilots (Mark Courtney and Stuart Procter) were only making two flights apiece before handing over and taking a break.  But all was not lost.  I offered the front seat of the Puchacz to Connor, and he enjoyed his first aerotow.  He had a great view of the tug and also later of Viktor taking off with Peter in CCY.

After Connor and I returned with the Puchacz Steve Westlake took Ashley Thomas up for an aerotow.

Ashley Thomas and Steve Westlake try out the Puchacz.  How does it compare with North Hill's Perkoz (both gliders are from the same Polish manufacturer)?

Another aerotow for Steve Fletcher.  This time, under the watchful eye of Martin Woolner, not Steve Westlake, but rest assured, we have a Steve running the wing!

In the heat and the very stable air, the demand for further aerotows was dwindling, but Scratch took Ged up for a second aerotow.

Andy, as ever had been looking at the weather and the Skysight forecast and booked the last launch.  The Eurofox would be "two up" with the tug pilots for their return to North Hill.  The plan was for them to tow Andy to the convergence visible well north of the airfield and up to 4,000 feet.  We bid farewell to the tug but not Andy, as we hoped to see him again!

The tail end of the convergence was Andy's target, visible in the distance.  More interesting are the Kelvin-Helmholtz clouds closer to the airfield (the undulating ones).  This is caused by different speed and direction air masses passing over each other, which might explain why we saw some "wave over cumulus" earlier in the afternoon, even though the wind speed was not enough to set up the normal Dartmoor wave.
With all having had their fill, in the heat, we started packing up.  DSGC members bade their farewells and headed for home.  Andy landed at 1700, not having found any lift under the tempting clouds that should have marked some nice convergence.  He derigged his Libelle and then headed to the east end to pick up another trailer.  I left him to it and headed home.  BBQ tonight.  The weather was certainly suitable, with the air temperature on the way back was 27C at Gulworthy.  Plenty warm enough to sit outside at home.

So our first aerotow Friday of the year.  Thirty-one flights; seven winch launches, and 12 aerotow combinations. Mark Courtney (our previous CFI)  commented, "A great day".  The great day included aerotow experience, aerotow currency, aerotow training, and aerial photography.  Was there a "Man of the Match"?  Yes, but not in terms of flight duration or escapades.  It was awarded to Ged, who came out of gliding retirement to fly with us.  Ged, we hope to see you again soon.

So let's have some more Fridays like this.
