Dartmoor Gliding News - Wednesday 13th September 2023

Forecast: Sunny, warm, light airs, some thermal activity.

Duty Instructor: Peter Howarth initially while waiting for Mike Jardine to return from his holidays (Ed: Mike, now that you are retired you are on a permanent holiday, surely?)

Duty Basic Instructor: Phil Hardwick.

 

Phil had a heavy schedule programmed with four visitors. Phil's first visitor was returning One Day Course candidate David Miles who started his One Day Course with Richard on Sunday 23 April.  After four subsequent failed attempts to complete his course due to adverse weather conditions David was back with us (Ed: That's determination for you!).

 

Peter Howarth started trainee instruction with David Moult whom I hadn't seen in a while  (Ed: Congratulations on your appointment as the DGS Membership Secretary).   In amongst David's set of three flights Phil took David Miles for a pair of flights, the second extended one indicated that the day was starting to be thermic.

After carefully observing the initial flights, none of which were soaring by then, Andy Davey took an early launch (Ed: For a privateer that is) and managed to climb and found a band of lift that appeared to be convergence.  Andy flew for two hours 1 minute before coming down to let his syndicate partner (Martin Broadway) have a go. What a perfectly balanced arrangement it was with Martin also soaring for 2 hours exactly.

When in the band of convergence Andy was climbing in a thermal when he noticed a bird of prey flying up and down the convergence line and maintaining the same rate of climb.  Andy acknowledged the expert and ran up and down the convergence line too.  Amusingly, Andy also reported that when he was at 3,000 ft he was joined by a pheasant (Ed: I know that they can be a bit dim but letting the updraughts take you to 3,000 feet is a bit more than a lapse of attention. On consulting t'interweb I found the following "Pheasant wings have a low aspect ratio (the ratio of wing area divided by wing breadth) of around 3.0 to 6.0 which allows them to explode into flight suddenly and are quite adequate for relatively slow powered flight, but not good for gliding").

The hat is back!  Peter watches David Moult climb during his fourth flight of the day.

Husband and wife team Crispin and Juliet Manners travelled from Kingsbridge for two trial flights apiece. After a short spousal discussion Crispin flew first but it was Juliet who got the longer flight!  Later in the morning both enjoyed soaring with Phil on their second flights.

Hot on Crispin's heels to fly was his wife, Juliet Manners, again with Phil (Ed:  Juliet, I think I found your pristine soaring hat. Its in the "lost and found" box in the club house.  A good reason to come back and use your three months temporary membership!)

Later in the morning Peter and David Moult observe Phil Hardwick and Crispin Manners flying in CCY far below them

While Andy was away in the Libelle Martin Broadway went for a quick warm up of 10 minutes in the K-8 while Richard took a pair of launches.

Richard launches his Discus ready for a cross-country flight

Once established aloft Richard decided to make the best use of the conditions by flying a 65 km cross country route: Brentor, Launceston, Liskeard, Yelverton, and then home to Brentor.  Here are some of the photos from his trip.

The Cornish village of Harrowbarrow with the railway viaduct over the River Tamar at Calstock in the far centre distance (Ed: The Calstock viaduct was built between 1904 and 1907.  It is the largest concrete bridge in the world and comprises 11,148 pre-cast concrete blocks.  Later concrete construction universally used steel rebar to make reinforced concrete).

Calstock viaduct (Ed: No! Richard wasn't this low)

Richard reports that the height of the cloud base was not good; varying from 1,800-2,400 feet for most of the day.  Odd bits were higher.  Alternatively one could go cloud flying like Andy up to 4,000 feet (Ed:  Don't try this at home folks! You have to be especially trained, qualified and the glider has to be fitted with additional instrumentation to go cloud flying).

St. Mellion Estate; A golf and spa resort (Ed: Having looked at their website Richard could have made today's flight several times in a club aircraft and it would still be cheaper than a round of golf on the Jack Nicklaus course!)

Richard's experience with the quarry at Hingston Down is that, providing its sunny, it provides a reliable thermal source.

Dave Bouchier climbing to cloud base at 2,600 feet with 8 knots of climb (800 feet a minute) on the vario (Ed: I see that Dave has marked his hat!)

Juliet Manners after her two soaring flights with Phil (Ed: I don't know how to break it to you Juliet but the glider pilots are all looking at the sky behind you as we are wont to do!)

Peter Howarth, having handed over the Duty Instructor responsibilities, to Mike Jardine set off in his Kestrel 19 and flew for 2 hours 30 minutes.

The never-ending wing of Peter's Kestrel 19 frames Roadford Reservoir (Ed: Is it full enough so we can start using water again?)

John Allan made the longest flight of the day in his Mini Nimbus (3 hours 16 minutes) and enjoyed the local scenery (Ed: John congratulations on achieving the final part of your Cross-Country Endorsement - you will be able to venture further afield soon).

While all this aviation was taking place Mike Bennett and Colin working on Mike's 205 Club Libelle. Just three simple jobs to do which inevitably didn't turn out to be simple at all.  Later a very "hot and bothered" Colin  flew in the K-8 for a quarter of an hour.

Hilary Anthony had travelled from Newton Abbot with her partner for a pair of trial flights.  Our new IFP, Steve Fletcher, stepped in to fly her while Phil headed to the hangar to help the team working on his syndicate's Twin Astir.

John Smith after a massive stint on the winch came up and took a pair of launches in the K-8.  Despite a little extension of one of his flights it was clear that the sea breeze had arrived from the south.  If you were already airborne you could continue to soar but the chances of getting away from just 1,000 ft launches in the southerly cross wind became remote (Ed: So Steve ate all the thermal pies then?).

Mike Jardine flew a set of three with David Archer allowing him to concentrate on the precision of his circuits and landing before clearing him to take a flight in K-8.  With Phil not back from the hangar I flew with David Miles for two flights to finish of his One Day Course.  The expectation of an extended flight was not to be with a 5 minute circuit followed by a 2 minute circuit as I launched into massive sink thereby awarding myself the "wooden spoon of the day".  As we opened the canopy after landing I could feel drops of rain from under the dark clouds above.  It was time to draw David Miles' course to a close.  Back at the launch point I presented David with his flight record/temporary membership card and we look forward to seeing him again and having the chance to make some soaring flights.

While the final flights were taking place we had  some walk-in visitors; Tom and Jasmine, who had walked up from Mary Tavy.  Tom had observed our glider flying for many years from his viewpoint at home and came for a look and a "trial fitting" as he is 6 foot 3 1/2 inches tall.  As expected, when strapped in closing the canopy squashed his hat flat. So no good for flying.  Ever the optimist I tried seating Tom in the back seat as he has long legs and a shorter body.  Unfortunately he couldn't fit there either.  Nevertheless I gave Tom and Jasmine a good introduction to our site and sport.  Tom was furnished with the details of our sister club; Devon and Somerset Gliding Club at North Hill.  One of their fleet of two seaters;  K-21, Puchacz, or DG500 may be able to accommodate him otherwise he needs to talk nicely to the T-21 syndicate (Ed:  A T-21 is an open cockpit side -by-side two seater).

A blast from a past blog.  The T-21 fuselage in the hangar on 17 August 2019 (Ed: That should provide Tom with sufficient headroom to be comfortable)

In summary; the day proved to be better than forecast with some good soaring to be had if you managed to connect with the lift.  It was enough for some to go cross country.  31 flights of which 15 were soaring flights which isn't too bad at all.

A final thought for those who were working on the new 205 Club Libelle, the Twin Astir, work in the hangar, and general administration.  Your work is appreciated.
