Dartmoor Gliding News-Saturday 10th April 2021

 Another high pressure day with the wind set firmly in the north and forecast to remain between 10 and 15 knots. RASP was suggesting some good thermal soaring starting somewhat later. So with this in mind rigging was a fairly leisurely affair end up with a Discus, ASW20, Open Cirrus, 2*Astir, Zugvogel 3B alongside the club SF27 and K8.

Clouds starting to appear
First launch at 11.21am was Rick flying his Astir who promptly fell out of the sky with a 5 minute circuit. A second launch saw Rick hook a thermal and climb away for a 1 hour 34minute flight only returning to let syndicate partner Mike Jardine have a go. Mike needed 2 launches before finally getting away for 1 hour 16.

Open Cirrus lifts off with some good clouds in view
From this you might gather that getting away was not as easy as you might expect. Thermals low down were very tight small bubbles and several of these were needed to climb from the less than 1000ft launches available today ( no headwind just the constant 10knots+ crosswind ) to 1500ft or so where the thermals were much more organised and therefore easier to use. Climbs from there were strong the best giving 4knots+ on the averager. Cloud bases rose quickly through the day to 3500 ft QFE.

Rick's view of Roadford Lake
Lots of good soaring was enjoyed with the longest flight being Steve in the Open Cirrus just 4 minutes short of 3 hours. Richard in the Discus and Phil in his Astir both recorded flights over 2 hours. 4 more pilots recorded flights well over 1 hour and 2 more around 3/4 hour.

Due to the strong northerly crosswind the stub runway saw plenty of action with pilots choosing this into wind option for their landing. 

Another good day.

Dartmoor Gliding News-Wednesday 7th April 2021

 With memories of wave flying over the Easter weekend, what if anything would today bring. The forecast gave a 10 knot northwesterly wind and rasp gave a very promising day with a 3 star rating. From the small group of assembled pilots three private aircraft were rigged. Rigging complete it was time to tow to the launch point, but the weather hadn’t read the forecast and a band of heavy drizzle had set in. Checking weather radars showed the rain would clear in about 30 minutes to be followed by a smaller band of rain. A socially distanced set of chairs was set up under cover to await for the rain to pass over.

Eventually the three rigged aircraft along with the club K8 were towed to the launch point.

Assembled aircraft at launch point.
Malcolm was volunteered to take the first launch in the K8 which lasted only 6 minutes. He then took a second launch for a flight of 28 minutes.

Andy Davey launched in the Zugvogel (HSH) for two flights. The second was for 22 minutes.

Steve Fletcher was next to  launch in the Open Cirrus (CGY).


Steve returned after 1 hour 13 minutes to claim flight of the day. He reported that once above 2000ft there was lift everywhere and no problem as log as you stayed high.

Steve climbing well at 3000ft
Phil Hardwick and I each had a flight in our Astir (FCJ). Phil managed a flight of 41 minutes. Gavin Short took the K8 for a couple of flights, the longest being 15 minutes. After working in the hangar with John Smith, Richard Roberts came to fly the K8 for a flight of 26 minutes.

Only eleven flights after the late start, but with the temperature falling and everybody feeling cold it was decided to end the days flying and de-rig and pack things away.

Thank you to everybody who were at the airfield today and contributed to a successful day.

Dartmoor Gliding News-Sunday 4th April 2021

Some readers may be pleased to discover that today was not another wave day..!  With the wind is west of north the airfield is no longer in the lee of Dartmoor and hence wave does not develop overhead.  That did not deter a small band of instructors/licenced pilots from gathering, however, to maintain currency – indeed the RASP forecast showed promise.  

A view of the hangar, clubhouse and MT building/workshops from 800ft
Agreeing to take two cables apiece, Gavin Short got the show on the road with a couple of short flights ( pun intended?).  Then Peter Howarth, fresh from the winch and with his eye ‘in’, took the K-8 to the north-west where he was rewarded by a thermal taking him to 1,600ft, at which point he was met by a strong inversion which firmly prevented him from getting any higher (this was confirmed by a pronounced haze line to the north).

Having been shown the way, Martin Cropper then attempted to emulate Peter by using the same geographic spot, but without much success, regaining launch height only once in a scrappy contest that severely increased the wear in the glider’s control linkages..!  Maybe RASP wasn’t so good after all.

Returning the K-8 to rest in the hangar, we reflected that, despite there being no wave (harumph!), at least we had been able to keep ourselves current, in preparation for the return to dual flying in a week or so’s time.  Special thanks go to trainee Ray Boundy who, in making the final member of our gang of four, made it possible for us to fly today.

Dartmoor Gliding News-Saturday 2nd April 2021

The club has restarted limited flying for licenced ( and current ) pilots flying solo only. 2 seat flying will commence soon.

The forecast for today looked very encouraging with the wind from the NE 10-15 knots; no rain. Looking at the atmospheric sounding showed windspeed increasing with height and a sharp inversion at around 3500 ft QNH. This gave an excellent chance for "wave" conditions. 

Arriving at the airfield confirmed these predictions, The sky was full of interesting looking wave bars and the trailer park was a blur of activity as the pilots assembled their gliders ready for the day. The private grid ended up as Astir, Twin Astir, Discus, Open Cirrus, ASW20, and Zugvogel 3B. The club fielded K13 G-CHXP with the SF27 on standby. Sensibly the K8 was left in the hangar.

Rigging well underway. The first aircraft is the Zugvogel 3B

Mike Jardine was first to launch in his Astir and promptly disappeared for 1hour and 5 minutes coming back only to let syndicate partner, Rick Wiles, to have a flight ( 1hr 45 minutes ).

Mike climbing well ( 5knots?) just over 3000ft....
.... and landing again.
So what was the flying like? Well let's have a look at my own flight. After Roger, one of my syndicate partners, had a quick half hour and, thanks to Andy, my other syndicate partner, who let me fly next, I got the Zugvogel 3B on line.  For those who do not know the 3B is a vintage wooden glider dating back to the 1960's with 17metre wings and surprisingly good performance with delightful handling. 

The launch was low as I had probably launched in the down going part of the wave. With just about 850 ft I did not have much time to find some lift. Pushing forward through fairly light rotor turbulence there was some smooth air with 0 on the variometer. I turned south and managed a short run with the vario showing just 0.5 knots up ( 50 ft per minute ). Turning north along the same run took me to Mary Tavy still at 0.5 knots. This was going to need some patience. After a couple more short beats I flew through an area where the lift was much stronger at 2.5 knots. The area was very small ( possibly a wave enhanced thermal?). So I turned very steeply to stay centred in the best bit and I was off, climbing well. After reaching 1500ft I was able to track north and south along the wave bar now marked by the cloud above and slightly west of me. The lift varied but I was now seeing 2-3 knots + on the averager. Excellent.

Above the clouds ( the wings are VERY dirty already )
Approaching Meldon Reservoir.
Interesting that the clouds north of the moor are in lines east west.
Another wave system? Why didn't I go and test it?
In what seemed like no time I had reached 3500 ft and was now looking down on the cloudscape. To the east there were 2 more wave bars, so with enough height to arrive above the cloud I could not resist and headed east at 65 knots through sink and rotor arriving in front of the next wave bar cloud where the lift was once again easy to use allowing me much longer beats from just south of Tavistock to Sourton in the north. I used this wave bar to climb to 4500 ft QFE (above the airfield) and then set off easterly once more to the most forward wave bar. The lift here was good and took me to just over 5000ft QFE ( nearly 6000ft above sea level ) and allowed the beat to extend a bit further being overhead Meldon Reservoir in the north. To the south the bar had a large gap just south of Tavistock. In the distance I could see where the wave bar reappeared but decided that, as Andy had not yet flown, risking a landout if it did not work would not be very friendly. Time to return to the airfield. A full airbrake decent just east of Mary Tavy was surprisingly quick. This was followed by a lively but uneventful circuit through the rotor back to the runway. Total flight time 1 1/2 hours.  

Me on final approach
I later found out from Richard Roberts ( Discus ) that the gap in the wave was mostly zero all the way south and that the wave clouds in the distance did indeed work and allowed him to explore the Plymouth and South Hams areas during his 2 hour 5 minute flight which was the longest flight of the day. I will know for next time.

As the afternoon wore on, the wave clouds thinned and eventually disappeared leaving a mostly blue sky populated by some narrow thermals to entertain the later flyers.

What a day. 22 launches in total with 1 in excess of 2 hrs, 4 better than I1/2 hours, 4 more better than 1 hour, 2 around 3/4 hour, and 2 more around 1/2 hours. A lot of these flights were limited  deliberately to allow others to fly. Average flight time for all flights today was 3/4 hour. 

A good Dartmoor wave day enjoyed with friends.

Dartmoor Gliding News-Friday 2nd April 2021

The forecast was for easterly wind 10-15 knots, so would it be a wave day?  However the wind hadn’t read the forecast and was due north about 10 knots on the ground. As there were only six pilots at the airfield today, it was decided to use the K13 and K8 for the days flying.

I took the first launch to do weather check. I flew towards the SW corner of Blackdown and found some lift. Although it was hard work, I thought it was a mixture of thermal and weak wave. I looked down towards the airfield and saw the K8 launch, only managing a quick circuit. I landed after 23 minutes having climbed to 1500ft and then losing the lift.

Next into the K13 was Scratch for his first flights after lockdown.

Scratch settling into the K13
As the morning progressed, Scratch, Andy Davey, Steve Fletcher, Malcolm Wilton-Jones and Gavin Short took turns to fly. All only managed circuits until just after midday Gavin and Andy managed slightly longer flights.

K8 taking off.
Just before 2 o’clock, it was Malcom’s turn to fly the K8. After launching he could be seen climbing slowly east of the airfield. Steve jumped into the K13 to try and join him. Malcolm was turning quite tightly and climbing away. Steve could not quite match him and landed after 15 minutes. Malcolm was now climbing a lot quicker and was obviously in wave and soon out of sight.

Andy meanwhile took off in the K13 and was soon climbing away.

Climbing well towards 3000ft
Malcolm eventually landed after a flight of 1hour 18minutes. As nobody else wanted to fly, I jumped into the K8. I managed a 48 minute flight climbing to 5000ft.

A very successful day with 20 flights, and it was worth waiting. The wave developed mid afternoon and made the day for the pilots who were able to take advantage of it.

Thank you to everybody who were at the airfield today and contributed to a successful day and smooth running including Scratch and new winch driver Gavin who produced good launches in the testing conditions..

Dartmoor Gliding News-Wednesday 31st March 2021

With lockdown restrictions being eased this week, a small group of the most current solo pilots gathered for their first tentative steps back into the air. After various discussions it was decided to fly a K13 and the K8. The aircraft were given a thorough DI and towed to the east end. Due to the very light wind it was decided to remove the west end fence in case of any low level launch failures.

The first cables arriving at the launch point.
After a thorough briefing, I took the first launch in the K13. The conditions were very benign, so it was time for the other pilots to prepare to fly. Andy Davey got ready in the K8 and Malcolm got ready in the K13.

Each pilot had three flights, mainly to prevent re-sanitising the cockpit continually. Steve Fletcher, Gavin Short, Hugh Gasgoyne, Phil Hardwick and Steve Lewis all took their turn as the day progressed.

Hugh Gascoyne happy to be flying again.

Most of the pilots were keen to make the most of the calm conditions and elected to continue flying.

And arriving back.
A very successful day with 35 flights, and all pilots leaving the airfield with smiles, very happy to be back flying again. No soaring with the longest flight of 10 minutes, but the circuits were just what was needed to start blowing the cobwebs away.

Thank you to everybody who were at the airfield today and contributed to a successful day and smooth running. A special thank you to Heather who retrieved all day providing the steady supply of cables.

Dartmoor Gliding News-Saturday 26th March 2021 Condor Racing

 Mistakes were made.

Task for this Saturday’s Condor Race

Booker, Bath North, Weston-Super-Mare, Bridgewater, Sherborne, Northhill. Distance 265km.


Wind 10 knots from NNW, Cloud Base 4921, 

Thermals Strong, Variation Medium,

 Width Wide, variation Medium

Activity = Low, Turbulence = Moderate

 Streeting = Low.

Aircraft = Any of the free gliders. 

Launch = Aerotow to 4000ft. Helpers and penalties as before.

All airspace is active, Bristol is Class D and we don’t have ROTL.

This is my first attempt at writing a gliding blog and as a newbie to the sport I was kept busy trying to find and stay in the lift, I wasn’t always aware of what the others (who were often several miles ahead of me) were up to. So I asked some of the other pilots to contribute their experiences of the race.

Pilots could choose from any of the free gliders that come with Condor, which excluded the beloved by some K6. Rick’s favourite Blanik was an option but for some reason, no one went with that. So this was the starting line-up.

Ed Borlase          Diana2

Alan Carter         Antares 18S

Hugh Gascoyne  Diana 2

Matt Howard      Duo Discus

Rick Wiles            Diana 2

Simon Vallance   Antares 18S

With a 10 knot crosswind the aerotow launch proved a little tricky for the inexperienced and although most got away cleanly, I managed to break the tow rope. Fortunately, I was able to restart without penalty and got away at the second attempt.

Once aloft I found plenty of active clouds within the vicinity of the start gate and set off with 5,000+ ft QNH. It soon became clear though that there were some big blue holes in the sky and that not all the clouds had strong lift and some didn’t seem to have any at all! (at least, not that I could find).

The first leg, Booker to Bath is long, over 100 kms and although others were steaming ahead I was flying at my own pace and was getting reasonable lift (average 5 up) form most of the thermals. As I neared Bath however, I hit a big blue hole and by the time I reached a reasonable looking cloud I was down to 1300 ft QNH and very close to the ground. I couldn’t find any lift so had to resort to pressing the thermal helpers key and eventually managed to claw my way up to about 4000 ft and was off again.

I managed to negotiate the Bristol airspace and made it to Weston but not before another couple of presses of the H key and a few more penalty points. By this time, I was way behind the front runners and continued to struggle to centre in the lift.

I eventually arrived at the finish twenty minutes after the leaders, feeling tired after three hours of concentration in a VR headset, and ready for a lie down.

By this time, Hugh had already landed out and Rick was still struggling to come to terms with accidental penalty points – see their notes below.

Rick’s blog.

I think the idea is for all of us to write something about this week’s task. I have decided to write about my worst part of the task, and why you shouldn’t let a teenager get inside your head!!

Part of the day’s task involved flying around some airspace. On our map Bristol Airport has markings drawn in for show it is class D airspace and needing a radio telephony operator license. This was mentioned in the morning’s briefing and also that no one has a RTOL. However, one of our members forgot to load the correct map. 

As I am sure you have read before there is a bit of banter that goes on when flying. Saturday was no different. As I was going around the class D airspace approaching the turn point at Weston-Super-Mare, I could see on the map that Matt was very close to the airspace. Not knowing that he couldn’t see the airspace Matt turn towards the coast, at this point I think Matt realized he couldn’t see it and so being clever he typed a message as a radio message asking for permission to transit the airspace. I couldn’t remember the correct key to press allowing me to type a response to deny him permission and started pressing some different keys to find it. 

Mistake 1. In my desperation in not finding it I started pressing more keys and ended up pressing the worst one. THE Q BUTTON. I shoot up 1000ft in height and in my horror looked at my points and had gained 150 penalty points. I dropped from top of the stack to 5th. 

Mistake 2. Not very happy with myself and the friendly banter coming over the headphones, I thought, it’s OK, not all lost. I have a good lead and if all goes well I could make up the difference. Time to covert the height I had to speed to gain some of the points back. I lowered the noise of the glider. Then something happened over the group chat, Can’t remember what now, but I took my eye off the ASI. When you are close to VNE this isn’t a good idea. The next thing I knew the flutter stated. Not wanting to pull back on the stick to hard I started to ease it back but too slowly. The next moment I was looking at the glider from outside spinning with only 1 wing attached.

Mistake 3. I needed to get this sorted quickly and started pressing F1 to get back in the cockpit. Losing so much height wasn’t good. I then corrected my mistake and pressed q which repaired my glider and gave me another 1000ft of height and then pressed F1 to get back in the cockpit, BUT AT A COST. Another 350 penalty points. And to top it all I was lower than I was when I first pressed Q.

One thing I take from this is thank god it was only on Condor and not for real and how easy it is to allow yourself to be distracted and never try to match wits with a teenager!!!




Hugh’s Blog

After previous tasks I had set out to fly a little more aggressively this time around, so I staunchly topped up the water to the brim and pushed on at 120kts plus on most of the glides. This worked to some degree - as in Rick was still within 10 miles of my position on the first Leg! The downside to this strategy was that I got really low (780ft QNH) but managed to scrape away. Ed and Alan had similar issues early on but both managed to escape field landings (or use of the magic Q button).

Buoyed up with the euphoria of avoiding a land-out, I set about staying with Matt, and for a time I actually held the lead position on the scoreboard. I tiptoed around the Bristol Class D zone, watching my PDA carefully with the display zoomed. I thought I saw a glider icon inside the blue lines, but it may have been a glitch with the system.

Rounding the first TP Matt and I headed for the restricted airspace around Weston Zor - requiring a maximum 2000ft QNH transit. We both managed to clear the airspace but had a battle to climb back up having exited the airspace very low. It was around this point that Rick fell victim to some penalty points - but doubtless that will be recounted herein by our esteemed Condor2 host!

I made the mistake of trying to bag the final turnpoint while still low, rather than going off track before to top up. Surely I would be able to find some lift? I made it to a good looking cloud but it simply wasn't working so I committed to making a safe landing. Turn back into wind, dump the water, wheel down, check the flaps and approach speed. As I rolled to a halt I screenshotted the scoreboard but knew I would be bumped further down the table when the others finished.

As it turned out, Ed won the day with Matt a close second. It was a really fun task and the perfect distance (265km) for a Saturday morning task. Good sky, Rick - Well done!
