Dartmoor Gliding News - Wednesday 28th August 2024

"Honey, Dartmoor Gliding broke the internet!", well all the the meteorological supercomputers at least, was one view.  It would not be an understatement to say that  the forecasts were "all over the place", was another view.  Whichever was right, it was still a mess. Last night RASP was "flat lining" with low cloud and rain, but this morning it forecast no rain, cloud base raising especially later afternoon.  Skysight predicted mediocre flying with regular rain showers.

Having checked yr.no the night before, and in the morning, for the local weather I expected to wake up to fog followed by heavy rain on the way to the airfield.  Not a bit of it it, and it was remarkably fine when I arrived.

The morning view at the club. What rain?

Preparations to fly were underway.  Club gliders were out.  Andy had fitted the repaired undercarriage door for the club Astir CS77 and had improved the fit of the other door.  Scratch had prepared two black strops ready for the expedition from Devon and Somerset Gliding club on Friday.  They are bringing a K-21 two-seater trainer with them which needs black links for the strops vice the brown links that we use for our K-13s.

Following an early brief, which promised no rain, the gliders were taken up to the east end.  The K-8 was again forlornly left on the apron.  More of that anon.

Today I had to sit the Bronze C exam again as preparation for my Assistant Category Instructor training.  This was to see how much I had forgotten since I took the exam back in 2003.  So I was left back in the club house with hopefully not too many interruptions to attempt the paper.

The start of the day

The first flights saw the approach of low cloud and rain. First in the air was Geoff who continued his training with a set of three flights.  Meanwhile Hugh, our duty Introductory Flight Pilot, took John Allan up in the Puchacz for a warm up before flying his visitors.

Geoff concentrates hard on his pre-flight checks

Of the five visitors on Hugh's dance card today, two were no-shows, probably on account of the weather which only got going at 3pm!  More of that later.  Hugh's first visitor was Gary Hughes, but his two flights were short and under leaden skies. Gary had a Royal Navy career spanning 37 years.  Previous aviation activities were with microlights at Solent Flying Club however, he wanted to tick the 'Gliding' box.  It was frustrating that conditions did not allow Hugh to give him a soaring flight.  His voucher was a birthday gift from wife Julia.  Now retired, he keeps himself busy working for the armed forces charity SSAFA.

Gary studies the instruments.  It's certainly different to a microlight!

Matthew, one of our juniors from last year, re-joined the club today.  Mike took Matthew for a set of three training flights and he was soon coordinating the controls.

Low cloud soon covered the airfield

Colin's arrival at the club heralded a heavy downpour.  I was dragged away from my exam, the Bronze Confuser as it is known, to help him move the K-8 back into the hangar and the dry.

Colin arrived and the heavens opened

And with that low cloud soon covered the whole airfield.

How low is low (cloud base that is not Peter's jokes)

The horizon starts to disappear

The rain radar trace on Glide and Seek shows us "what we are about to receive".

Whilst waiting for the rain to hit Andy, after mending the Astir CS77 undercarriage doors earlier and winching all morning, had to return home for the mundane task of dog sitting.  But, as he found out it was glorious in Barnstaple and just had to tease us with this photo.

Andy's view of the riverfront at Barnstaple

Around 1215 we ceased flying as more rain and low cloud came. Members patiently waited for the skies to clear.  After a frustrating wait of two hours, whilst regularly consulting weather apps, flying finally recommenced.
 
Meanwhile I was dragged away from my paper by Colin to review some paint issues with the recovering of K-13, CCY.  After lengthy discussions I could get back to my exam.  Later Mike turned up and marked the paper.  83.3% (the pass mark is 70%) (Postscript; the pass mark for instructors is 80%!) with a couple of areas where I need to revise.  Earlier, trainees Neal and Geoff took an interest in what I was doing and what, in due course, they needed to know. So here is an example.

"There are three radio masts at Rugby. What is the height of the tallest mast above the ground?"
And yes, it has become a trick question because presumably there were radio masts on the 2013 chart when the paper was set but not in the 2024 chart which has wind turbines instead.  I told you it was confusing!

Later in the afternoon as the cloud started to clear. Neal took a launch to practice his circuit, three times. Then it was Loraine's turn for her set of three circuits.

Neal looks down on some clouds too
Loraine brings Mike back to the ground.

Dark clouds gradually moved away

John Smith tried his hand in the Astir CS77 for a couple of circuits. Then Peter showed him how it should be done and stayed up for 12 minutes, impressive considering the mediocre conditions.  Mike, having worked through the list of trainees, took Geoff up for a further flight.

Low cloud still hanging about

With a no show from the 1200 visitor, Luke Whattler was Hugh's second 2-flight visitor. Luke is a facilities engineer at Plessey in Roborough. His family saw the 'Learn to fly a Glider' sign on the Tavistock road and found us from there! Once again the conditions, although improving, still thwarted any soaring, but Luke enjoyed his flights with a little taste of soaring on his last flight. Being a local living in Gulworthy he may be back again.

The sun is out.  Hugh and Luke are ready to fly.

The sun is still out after their flights.  Conditions are slowly improving.

Although brightening up on the ground it was still gloomy in some directions as seen from the K-13 cranking out the circuits with Mike

By the time Hugh flew with James Paxman, the last visitor of the day for his single flight voucher, conditions were picking up with the transit of the cold front from the west.  Hugh managed an extended soaring flight (or should that be a scratching flight), with most of it at around 900 feet. James thoroughly enjoyed the thermal turns and is enthused to take up some training, so perhaps we'll see him again soon!

With the visitors' flights complete Scratch took the Puchacz.  He co-opted Matthew's Dad and took him aloft for two flights, including some soaring, to show him what all the fuss was about.  Mike took Matthew for another training flight in which they soared for 12 minutes.

Meanwhile John Allan took the club Astir CS77 for a second flight now that the cold front had passed, and he soared for 47 minutes. He took the "Man of the Match" albeit in vastly different conditions that were experienced by the rest of today's pilots.  I am not sure if that is the longest flight to date in the Astir CS77 but it's clear that its a very competent machine and it can soar; even better now that it's got both undercarriage doors fitted!

John Allan returns from the soaring flight of the day for a hangar landing
Late arrival David Archer took a couple of training flights with Mike at the end of the day and finished up with a hangar landing.

Considering the weather, rain and more rain, I think the Wednesday Wavers did very well cracking out 30 flights with a smidgen of soaring thrown in as well.

Roll on Friday which is the first day of the three-day expedition to Dartmoor by members of Devon and Somerset Gliding Club.

Dartmoor Gliding News - Monday 26th August 2024

Another bank holiday. I had offered to open the field to enable solo pilots to fly and the usual group of self-authorising pilots. A forecast for a moderate south-westerly wind, possible soaring although thermal height would only be 2500ft AGL. Scratch had offered to fly with a few trainees to offer some thermalling advice with upper air work.

A club K13 and Astir 77 were joined by private gliders DG300 (HME), Libelle (JEU), Kestrel 19 (DBK), Libelle (CLM) and Twin Astir (DSL). The first flight with Scratch and Freddie Purkiss saw them managing to climb created a line of single seaters to form ready to launch.

The sleek DG300 ready to launch.
Returning member Josh Wehner arrived with friend Toby Robinson. Both flew with Scratch and each enjoyed soaring flights.

Josh and Toby with Scratch.
The solo pilots were enjoying various amounts of success. Steve Lesson (Astir 77), Malcolm W-J (Twin Astir) and Sean Westrope (Libelle) unfortunately drew the short straws. Mark Elliott (Astir 77) managed 43 minutes, myself (Kestel 19) with 1 hour 17 minutes, Phil Hardwick (DG300) with 1 hour 41 minutes only topped by Andy Davey (Libelle) with 2 hour 8 minutes to claim flight of the day. All flights were completed below 3000ft AGL.

The wind again today remained with a more southerly component and was starting to increase in speed. Scratch took a last couple of flights in the K13 with Val Kiely and I then took to the back seat to fly with Alasdair Barclay and finally Freddie Purkiss. This enabled them to both practice cross-wind approaches. Freddie's was combined with a hangar landing. All were well flown by the trainees.

Thank you to all at the airfield today. All flew and we managed 15 flights with an average flight time of 33 minutes.

Dartmoor Gliding News - Sunday 25th August 2024

The forecast was for a moderate south-westerly wind increasing as the day progressed with the possibility of light rain late afternoon. However the wind had a more southerly component, so a crosswind and plenty of lay-off on the launch. With a number of trainees at the club today it was going to be a busy day.

First up, Julia Old who is progressing well and coped well with the cross-wind launch and approaches.

Julia thinking about the flight.
Returning member Darren Clark flew with BI Scratch to continue improving his basic skills.

Duty IFP Steve Fletcher had two visitors today. Due to the forecast they were asked to attend earlier than their booking time to hopefully be able to get their flights in. First to arrive was Paula Robinson who enjoyed two flights including an extended circuit.

Paula receiving her certificate.
Next to fly with Steve was Finn Clark who experienced two circuits.

Finn and Steve ready to fly.
Trainee Jamie Young was next to fly with me. Jamie is progressing well with his training and needs to start finessing his general flying and making his own decisions.

Happy Jamie ready to fly.
The Twin Astir made an appearance. Phil Hardwick flew with syndicate partner Robin Wilson.

Robin and Phil in the Twin.
The rain forecast to arrive late afternoon made an early entrance at 1 o'clock and forced a stand down for 40 minutes. A clearance allowed new member David Osment to have a flight before another band of rain arrived.

David discussing the flight with me.
A further wait of 20 minutes passed before what ended up as the last two flights of the day. Val Kiely flew with Scratch and Frddie Purkiss flew with me. The strengthening crosswind was proving too much and it was decided to put the toys safely back in the hangar. As we finished packing away more rain appeared vindicating the decision.

Val with Scratch.
Thanks to all at the club today, particularly those who were unable to fly.

Peter Howarth.

Dartmoor Gliding News - Wednesday 21st August 2024

The Forecast: Met Office Yellow warning for heavy rain, gales, difficult driving conditions. Up to 100 mm of rain on the slopes of west facing hills as a plume of humid air, the tail end of a hurricane hits....in Scotland

On the way to the site above the club, I spotted some Kelvin Helmholtz clouds (an extremely rare phenomenon, where a cloud produces a billowing wave pattern. They occur when there is a strong vertical shear between two air streams, where winds to blow faster at the upper level than at the lower levels.).  However, that didn't match the Met Office's 214 forecast on wind strengths during the morning briefing.  Strange.
Are these Kelvin-Helmholtz clouds over the site?
Meanwhile on Dartmoor, the Wednesday Wavers were preparing for a day's flying. Mike Jardine as the Duty instructor and Richard Roberts as the duty Basic Instructor: A One Day Course and two two-trial flights.  Richard was delayed as he had to collect his glider trailer and bring it back to DGS, so I gave the brief for the ODC and was ready to spell Richard on flying today's visitors if required.
Mike watches Gavin's brief to our One Day Course candidate and some visitors.  Should have gone to Specsavers!
The day turned out to be a grey one, with sprinkles of rain from time to time.  The cloud base rose enough for flying operations, and occasionally there were tantalising bits of blue sky and sunlight peeping through the clouds.  Let's not get excited. It wasn't much as evidenced by the flight log; only two of 36 flights could be classed as soaring with visitor Peter Brown and me, and trainee Geoff Cooper and Mike Jardine managing to get the "Men of the Match" award with a heady 12 minutes apiece.  Yes, it was a day or circuits, but a lot got done nevertheless.
Overcast skies settled in for the day
Loraine managed a set of early flights and progressed her training with an emphasis on pre-flight checks, then junior Jamie, and previously mentioned Geoff, made their sets of training flights with Mike.  Mike commented that it was "good to see Loraine and Geoff progressing with the coordination of the controls". 
 
Navy instructor Jamie Steel called in at DGS later for a short visit and took some of the load from the Duty Instructor by flying Viktor focusing on his round out and landings. Jamie remarked that "Viktor's landings are improving".

After a well-earned break, Mike continued club training with a set of three flights with Neal.

Neal, there is a secret to Go-Pro cameras.  They don't improve your flying but do attract lots of critiques from your fellow members when they view the footage. Beware the two-edged sword!
Neal mastering straight flight
Solo pilots, Steve Fletcher and Malcolm, made use of our single-seater Astir CS77 which is proving to be popular with club members.  Meanwhile, having worked through the flying list Mike took each trainee up for a fourth flight of the day.

Richard flew candidate Alan Wilkinson on his One Day Course.  Alan hails from Westward Ho!  Although the visibility allowed sight of the north coast of Devon from time to time he couldn't see his home town.  Although Richard and Alan only had short flights in the Puchacz Richard covered the effects of the primary controls.  His instruction was evidently very successful as Alan was on "Cloud Nine" when I saw him after his visit to the winch. Alan said that he aims to come back and fly some more with DGS.

Alan takes control!
So, Alan, were you happy with your course?
After Richard had finished with the Puchacz the kids got to play, with Steve and Hugh taking a refresher flight in our Polish beauty.

A thing of beauty.  The glider that is, not the occupants!
 
A pair of yahoos somewhere over Dartmoor!
Before their flight in the Puchacz Hugh and Steve made a warm-up flight in K-13, FSD
Our first visitor of the day was Peter Brown from South Brent who was accompanied by his wife.  A former Royal Navy officer, it was appropriate that he flew with me in the Puchacz whilst Richard and Alan were having a break. Indeed, it transpired that we had both flown Chipmunks out of Roborough, Plymouth, as part of our naval training many decades previously, and had shared the same dare-devil ex-Battle of Britain instructor.  What a small world.

Peter Brown ready for his first flight, while a pensive Gavin considers his pre-flight checks
Peter experienced some soaring on the first flight; thermaling and gaining height by just pushing into wind.  On his second flight, he tried the controls and saw the effects of the elevator and ailerons.  Peter was fascinated with the power and speed of the winch launch and that we managed to climb a hundred feet or so, a number of times, whilst the cloud cover was total and not a speck of sunshine was falling on the ground.

Peter Brown receives his certificate from Gavin whilst Alan Wilkinson is strapped in ready to continue his One Day Course with Richard.  It's all go at DGS!
Our second visitor was Sally Altman with her sister and their children.  Sally's brother-in-law, Chris Taviner, had bought a two flight voucher but sadly was working on shift and couldn't be there to witness her flights with Peter in K-13, FSD.  Sally had never been in a small aircraft before.  She works in HR for Emirates (airlines) and is based in Dubai.  Disappointingly, Peter was unable to provide trolley service during her flights, but that didn't stop Sally having a great time.  Sally, we wish you a safe journey back to Dubai tomorrow.

Sally's second flight was a hangar landing. After parking the glider ready to enter the hangar, Peter hands a delighted Sally her Certificate
So a day of nothing weather wise but a lot of training, visitors flown for trial flights, and a One Day Course delivered.  As ever the Wednesday Wavers rose to the challenge.  Special mention must go to the drivers of the manual winch today, especially those who didn't get to fly; Andy and Phil.  Thank you.  I am sure that you will get the favour returned... on a soaring day.

Is the K-8 getting jealous of the club Astir CS77 receiving all our solo pilots' attention?
The end of the day.  Gliders queuing to enter the hangar.
A final word from the duty instructor: "Thanks to all for making a good day out of the poor conditions". 
 
Postscript: We have received news from former DGS junior Freddie Colton who went solo with us before he headed off to Aberystwyth University, to read Electrical Engineering: 

"Unfortunately, life has proven too busy for me to get any gliding in this year, though you will definitely see me again at DGS, hopefully next season. Also thank you and everyone else at the club for your help as I have just completed my first powered solo at the Universities of Wales Air Squadron (UWAS)."

Congratulations Freddie. We hope to see you again soon.  We promise not to make you wear a life jacket6!

Freddies's instructor congratulates him on going solo in a Grob Tutor Mk 1. (known to the rest of the world as a Grob G115e)
