Dartmoor Gliding News - Saturday 21st September 2024

As always the weather would be key to today. There were dire warnings of potential thunderstorms and torrential rain. Initially there was a lot of low cloud. In fact for the first couple of hours Brentor Church was not visible from the West end launchpoint. The wind was easterly as forecast; forecast to be anywhere between 6 and 15 knots, The soundings did not look great for wave. The wind strength was not really increasing with height and the inversion was weak. However, at DGS we have learned that if the wind has some east in it then there is always a possibility of wave. Today was no exception

Looking towards the east. Wave cloud at the top of the photo.

As the cloudbase started to rise. Rick and I took the opportunity for a couple of practice cable breaks for my BI revalidation while there was not enough height for a full launch. Shortly after this, it was apparent that there was a wave slot out over the valley and it was game on. Andy Dave and Sean Westrope launched in a brace of Libelles and promptly disappeared.

"We launched K13 G-CFSD through very mild turbulence ( probably rotor ). Releasing at 1350 ft we pushed forward to the east in lively rotor. Just before the edge of the cloud, the lift smoothed out as we entered the wave. Once in front of the cloud the lift increased to a smooth 4 to 6 knots knots which we used to surf north and south up through a long(ish) gap in the cloud eventually popping out over the top at 4600 ft, where we were treated to a fabulous vista with a bright blue sky above with a shining white cloudscape. From this vantage point it was obvious that we had climbed up using a secondary wave bar; the primary was still well to the east of us. but it's cloud top seemed to be about the same height. Had I been flying solo I would have pushed forward to the primary but as this was a lesson, the gap we were in provided a great chance to delivery the controls lesson. After half and hour or so the gap started closing, initially with bridges forming between the upwind  and downwind cloud banks. Time to go. A high speed, full airbrake decent brought us down into the dark grey gloomy world below the cloudbase for an uneventful circuit and landing.".

Gavin Short also got to the wave in his Standard Cirrus. Here are some of his photos.

As the day warmed up the wave system broke down with most flights scratching around for little bits of thermals. However, when the afternoon cooled the wave reset and after 5pm there were several more extended wave flights.

The wave reformed in the early evening
We had a couple of visiting pilots today. Michelle Strickland and James Fowkes where in the area from their homebase at Rattlesden Gliding Club, an ex bomber command airfield near Bury St Edmonds to explore what flying in hilly terrain would be like. Their home site is surrounded by absolutely flat countyside. They had a couple of check flights each before flying the Astir on and off throughout the day.

As always, club training continued at pace. Highlight of the day for me was the Zack Smith's first flight controlling all of the launch and landing. Well done.

Zack looking laid back after his sucess.
A busy day with some great wave. And the dire warnings for torrential rain and thunderstorms - we didn't see any of that at all.

Dartmoor Gliding News - Wednesday 18th September 2024

 With recent excitement regarding the possibility of wave today on the forum and chats the early activity at the club when I arrived indicated the optimism. The forecast easterly was in practice more north easterly, but there were signs around that there might be wave present.

Andy Davey was keen to get in the air, so after a morning brief he took a launch. His account follows:-

Wednesday wave. I was meant to be at Portmoak in Scotland for the wave but with easterly wind forecast there was no chance. So was it worth the 588 mile drive home for the wave at Brentor? There was evidence of wave when I arrived at the club so with the glider on line I took a launch to 1650ft (thanks Richard). I now needed to make a decision go straight out towards the moor or turn left and head for some wave looking cloud I made the wrong one when I arrived at what I thought would be a wave bar I found nothing but sink and at 750ft had to scuttle home. Luckily the second cable was still there so I took a second launch at the top turn left towards a good looking wave bar. Just over 2km north of the field contacted the lift and started to climb away slowly at first then the lift improved. Once above 4500ft was able to use the wave over the danger area and eventually managed a clime to just over 7800ft. The lift then started to fade so I decide to see if there was a wave bar down wind of the airfield and there was one running from Gunnislake to Roadford but this was also fading so it was time to land. Was it worth the drive yes. Moral of the story the early bird catches the wave.

Andy established in the wave.
Climbing well at 5500ft.
I took a quick launch in the K13 to check conditions before training began. With little turbulence on the launch and approach it was deemed suitable for both training and visitor flying to take place. I would gradually work through the list of trainees today. John Osment, David Osment, Geoff Cooper, Viktor Skochko and Loraine Kindley. All made progress in their individual ways.

Viktor keeping a good lookout.
Hazy view to the south.
Duty IFP today would also have a busy schedule today with four visitors. Hugh's first visitor was Ollie George. A 2nd year student from South Molton. An 18th birthday present from his parents, he enjoyed two flights thrilled with the launches and aspires to be a pilot.

Ollie ready with Hugh.
Returning visitor Clare Matthews had a flight with Hugh before the next arranged visitor Peter Northmore arrived. Peter is a retired probation service employee from Launceston. He had three flights the third of which was an extended flight in weak thermals.

Jim Bishop was next to fly with Hugh. Jim is a drone pilot so was at ease when Hugh side slipped on the approach of the second flight.

Jim ready to go,
The last visitor today was Richard Follett. A retired CAD and 3D rendering specialist was bought the voucher as a birthday present. He arrive with friend Jim Bishop to share the experience with.

Richard with a happy Hugh.
Clare who flew earlier had another two flights with BI Scratch and her partner Paul Mitchell had two flights with BI Gavin to end a good day flying. 42 flights achieved flying from the west end is always a great day. Only one wave flight, but all had a good day flying. Thank you all for your help today.

Dartmoor Gliding News - Saturday 14th September 2024

The day started with mostly blue skies with just a few cumulus over the top of Dartmoor. The wind was light from the south, So we would be launching from the east end. We fielded 2*K-13s, Puchacz, Astir and a K-8 from the club which were joined by Dave Archer's K-6 later.

Right from the start there were a few thermals about, enough to keep the K13 soaring which topped out at a dizzying 1300ft in the blue. The cloudbase rose fairly quickly, and eventually some cumulus clouds formed making the task of finding thermals a bit easier. The light southerly strengthened somewhat and veered gradually finishing as SW by the end of the day. 

Light crosswind on a very blue day
The solo pilots obviously decided that today was a K-8 day and mostly ignored the Astir to record flights of 24 min, 24 min, 18 min, 1:02 hr ( longest flight of the day by Alasdair Barclay ), 54 min ( you had Alasdair worried Malcolm ), and finally 10 min for the hangar flight at the end of the day.

The 2 seaters were not left out though recording lots of flights in the 15 to 25 minute range. Considering that the accompanying instructors were delivering their chosen lessons at the same time this was a good result. Spotting an opportunity, CFI Rick Wiles took the Puchacz and trainee Jamie Young up for 34 mins during which they gained enough altitude to begin Jamie's spin training. The sight of the Puchacz spinning is quite impressive from the ground.

K-13 ready to go
An off they go
Our visitors today were Graham Stearman - One Day Course, Dan O'Sullivan and Philip Judge - Air Experience flights and Jason Davies who was returning after his One Day Course a couple of weeks ago.

Dartmoor Gliding News - Sunday 15th September 2024

Forecast for some light south westerly wind, overcast day with some possible soaring and a smaller turn out due to some members being away at Duxford for the air display it was going to be easier day for all.

David Moorley was first into the hot seat. David continues progress growing in confidence with general flying and improving with approaches and landings.

David flying well (you can just see the yaw string in the middle).
After David, next was Darren Clark. Darren is a new member and is getting acquainted with coordinated turns. Julia Old, who has now signed up as a full member was next to fly with me. Julia is growing in confidence after her break from gliding and progressing well with her flying.

Julia keeping a good look out.
Duty IFP Steve Fletcher had three visitors today. First to arrive was 78 year old Robert Frost. Robert and family. He enjoyed two flights, the second of which was one of the rare occasions today when they got to cloudbase of 1500ft.

Robert looking forward to his flights.
Next to arrive was Mary McArdle who had two extended circuit flights with Steve.

The last visitor today was 14 year old Riley Dunn who enjoyed his two short flights with us.

Last to fly with me was Freddie Purkiss. Freddie is progressing well and today experienced his first go around launch failure.

With time progressing and all having flown it was time to organise some hangar flights. After flying George Purkiss as a reward for helping around the field today, Freddie stepped into the front seat of the Puchacz to be flown by Steve. Meanwhile after a sterling effort on the winch I took over from Phil Hardwick so he could fly soon to be returning member Ray Boundy in the K13 for a hangar flight. After Ray was beaming realising what he has missed whilst away on his travels recently.

A small crew today that made the most of things.

Dartmoor Gliding News - Wednesday 11th September 2024

Monday this week brought a distinctly autumnal feel with cooler North Westerly winds which set the scene for today.  With our many juniors back at school the Wednesday Wavers would have the airfield to themselves. So the day was bound to have a different feel too.

Summer's gone!  The croquet pitch at Cotehele stands empty in the autumn sunshine
I was late on parade as I had to take my son for a doctor's appointment.  At 28yro he should have learnt to drive by now!  When I arrived flying had just started.  The two K-13s were busy at the east end.  The Puchacz had not been taken to the launch point but the K-8 had.  The Astir CS77 however, was ranged in the hangar for its annual inspection.

Peter Howarth was standing in as the Duty Instructor as the Wednesday Waver's normal instructor, Mike Jardine, was on holiday.  Hugh was the duty Introductory Flight Pilot with four visitors to fly. 

Peter and Hugh took a weather check flight to confirm that the conditions were "lively, but flyable".  David Moorley had some training flights with Peter in some challenging conditions that challenged his final approach skills.  Normal conditions will feel like a walk in the park next time.  Later David admitted they the conditions were too lively for him but he learnt a lot from the experience.

In the hangar the inspection of the CS77 was underway.  While the glider was rigged its control surface deflections were measured by Colin and Phil.  Then it was derigged (de-armed as the German's term it) to allow a complete inspection of the fuselage, the wings, and the tail plane.

The resplendent Puchacz belly dolly, constructed by Andy Davey has better wheels and a lifting mechanism, handily also fits the Astir CS77.
Use of the Puchacz's belly dolly in the hangar meant that at Mike Bennett didn't have to bring the Astir's trailer down from the east end, which he was preparing to do.

Andy and Phil examine the wing fittings in the fuselage
Raising the tail made for a much better working height to check the innards of the fuselage.
After their early afternoon flights Peter reported that "Loraine and Geoff made good progress with their coordinated turns and their general flying skills in the testing conditions". 

It was a difficult decision today whether to fly our visitors, as the rain showers gave way to brighter, but gustier conditions which perhaps were borderline for trial flights.  We took care to warn our visitors, and that there was the opportunity to postpone, but all rose to the occasion.

Kevin Duncan, an electrician from Langport, was Hugh's 1100 visitor. His voucher was a gift from his partner.  Hugh reported that Kevin was "a very jolly chap" who thoroughly enjoyed the soaring, which Hugh managed for 14 minutes after an initial very short flight.  Kevin had some prior experience of hang gliding, and seemed quite happy to experience the exciting conditions.

Kevin and Hugh after their soaring flight
Hugh's 1200 visitor was Trish Doyne-Ditmas, a foot care specialist from Ivybridge.  Her voucher was a birthday gift from her family.  On her first flight she experienced an extended soaring flight before Hugh had to push back into wind from Mary Tavy to land at the airfield.  She clearly enjoyed the experience and snapped away with her smartphone.  Wisely, she deferred her second flight to a later date, hoping for calmer conditions.  We look forward to seeing you again Trish.

Trish and Hugh after their soaring flight
Hugh's 1400 visitor was Clare Matthews, a GP practising in Cullompton, living in Silverton.  Some friends had bought her the voucher.  She had three short flights in the choppy conditions.  She managed to enthuse her partner to take a flight, such was her excitement!  Steve Fletcher did the honours later in the day but before then he took a pair of refresher flights with Hugh to get acquainted with the conditions.

Elizabeth and Hugh after their flights
Keeping our pilots and the visitors in the air was Malcolm on the winch and John on the retrieve.  As solo pilots they would have looked forward to flying the K-8, as the Astir CS77 was offline for its inspection.  The lively conditions precluded use of the K-8 and so they flew with the Duty Instructor in a K-13.  Both enjoyed soaring flights of 26 minutes and 36 minutes respectively.  Towards the end of the day David Archer also took a flight with Peter.

Liz Kennerley was Hugh's last visitor of the day. She was, at her own admission, very apprehensive so he kept the turns very gentle on her first flight where they managed to soar to 2,000 feet above the airfield.  She appeared to have overcome her concerns and took a second launch and enjoyed another soaring flight.  Afterwards admitted she doubted if she would do it, but was very glad that she had done so!

Elizabeth and Hugh leave the thermal to the north whilst Malcolm heads to pastures anew, to the west, with Peter along for the ride.
A jubilant Elizabeth at having overcome her initial fears and sampled soaring flight
But that was not all.  You will recall that Clare Matthews had twisted her partner's arm to try a flight.  Paul Mitchell bought a voucher and strapped in with our other Introductory Flight Pilot, Steve Fletcher.  They made the best use of the improving conditions with a fantastic soaring flight that topped out at 2,700 feet AGL as a result of 6-8 knot thermals. It was booming! Sorry Clare, maybe you will be able to soar next time.

Steve Fletcher looks on as the happy couple (Paul and Clare) are reunited after their flying experiences today
Back in the hangar, the annual inspection was wrapping up.  There were no problems just routine maintenance and some TLC needed.  The glider was reigged, Duplicate Inspections made of the critical connections, and Positive Checks of the controls were conducted.  Tape residue cleaned up and the tail plane and wings were carefully taped, as were the undercarriage doors.  A new tyre pressure label was fitted to Andy's recently repaired undercarriage door.  Canopy on and final checks made before putting it back on a dolly for hangar packing.  Colin would work on the paperwork the next day and we should have and Airworthiness Renewal Certificate, to be put in the glider, on Saturday prior to its test flight flight (all club aircraft rigged after disassembly require a test flight).

Hugh took the penultimate flight of the day, at 1713, with John Allan (as ballast!) and they shot up to 2,000 feet straight off the wire.  This gave John a chance to look at the view and take some photos.

Looking to the north; Devon's green and pleasant lands.  The evening light always makes the grass glow greener.

After finishing the work on the Astir CS77 I headed to the winch and co-opted Phil, who had an extended stint on the winch for much of the day after working in the hangar with me, to take a mutual flight.

Ready for the final flight of the day. Is that Gavin having a nap or squinting into the afternoon sun?
Alas, a repetition of the flight Hugh and John had just realised was not to be.  A 1,250 foot launch followed by some scratching in zero sink to the north of the airfield had us on the ground in seven minutes.  Anticipating the wind shear the approach speed of 65 knots produced an almost zero air brake hangar landing to stop safely by the cross track.  Fascinating conditions.

Gavin and Phil end the day with a hangar landing
The launch point team then had to walk the K-8 back to the hangar after its outing to the east end for some fresh air, because sadly was too windy for it to fly today.

Gavin toes the "Bourchier line" whilst bringing the K-8 back to the hangar

Today we made twenty-six flights in testing conditions for both our trainees and our visitors.  The passage of the cold front made for a pleasant, if gusty, afternoon and evening.  Thanks to all for making a challenging day enjoyable.  Further thanks to those who were working in the hangar, or running the field, and didn't get a chance to fly.
