Dartmoor Gliding News - Saturday 11th November 2023

Today was the lull before the storm and allowed us to get some very gentle flying in. The temperatures overnight dipped to about 6°C in the city and as low as 3°C in the Dartmoor valleys. This left the day feeling decidedly chilly. RASP was again hopelessly optimistic.

The forecast suggested a light SE breeze. Launching from the west end early flights found low level orographic cloud laying in the valleys ( above the streams and rivers? ) in absolutely smooth air.

Most flights were slightly extended circuits but late in the afternoon a "feathery" was spotted under a particularly dark cloud and this allowed Gavin to record 13 minutes with his passenger in a K13 only to be followed by John Allan in the K8 who recorded 19 minutes.

Late afternoon "interesting clouds
We had four air experience visitors today, Terry Pullen, Kekelomo Somore, Ibukun Ajai and James Parmenter each of whom was flown by a different BI / IFP as we shared out the duties to keep our collective hands in.

Dartmoor Gliding News - Tuesday 14 November 2023 - The Puchacz arrives

What, a blog on a Tuesday?  Alas, we didn't go flying but I went on a very special aviation roadtrip to LTB Glider and Motor Glider Services, better known as Les Clark's, which is at Ogbourne St. George, near Swindon, to pick up a Royal Navy two-seat glider that has been loaned to Dartmoor Gliding Society.

Heron Gliding Club which operated at RNAS Yeovilton was put into hibernation in 2020 for a number of defence reorganisational and other reasons.  However, the need for naval personnel to fly gliders, which is a recognised Adventurous Training activity has not diminished.  Andy Farr the former Chief Flying Instructor at HGC has been appointed as the Chief Flying Instructor at the Park (which is the home of the Bath, Wiltshire, and North Dorset Gliding Club).  He is encouraging naval personnel who would have flown at Yeovilton to fly at the Park.

This triggered an idea to encourage naval flying by personnel serving in the Plymouth/Devonport area at Dartmoor Gliding Society and build on the navy flying we have been conducting with courses from HMS Raleigh this year.  The quid pro quo is that we operate a navy glider at DGS.  I am pleased to report that after almost four months of negotiations and preparations I went on a road trip today to collect G-EHCC which is a Puchacz two-seat training aircraft.  HCC was built in 1992 for those who like these details:

My log book recorded: 13 September 2002.  Flight No. 46.  Puchacz SZD-50-3.  G-EHCC. Aero tow. P1.  15 minutes.  First solo.  2,000 ft aerotow.  Thermalled 100' in weak lift.  Circuit modified to turn inside another glider in circuit.  Good approach/control. Landed close to other glider.

And here is HCC in its previous natural habitat at RNAS Yeovilton, flown by our very own Martin Cropper.

Now that HCC is at DGS. The plan is to take one of the K-13s off line, rig HCC, and put it in the hangar. We can't keep the trailer it arrived in so we will take measurements and photos and kit out our refurbished AMF twin-axle trailer to accommodate the Puchacz.   For future developments the committee is exploring the option of building a T-hangar to accommodate the Puchacz.

The journey to Brentor:

So a long day on the road for me, mostly in torrential rain (hence no photos at Les Clark's), but an exciting day for DGS as we "dip our toes" into the world of glass.  What will Wednesday bring?

Dartmoor Gliding News - Wednesday 25 October 2023

The forecasts, and the actual weather en route, looked quite nice this morning but as I approached Brentor the moors were cloud bound and at the club bands of rain were sweeping the site.  Time to light the wood burner (Ed: It is autumn you know?) and put the kettle on.

So a slow start to proceedings. The stalwarts set about sorting some of the electrical problems on our machinery while Andy Davey conducted some "dodgy" deals with secondhand Flam units (Ed: As Fleet Manager you can't object to further fitting of Flarm to club and private gliders).

Returning junior Toby Irons arrived smartly with his mum, Sarah and his younger sister Charlotte.  The latter made good use of the wood burner and the clubhouse WiFi.  Following the progress that Toby and I made on the effects of the controls on Sunday, I delivered the ground lecture on the "effects of the rudder", ready for either I or the Duty Instructor to conduct the airborne demonstration and exercise.

Steve Fletcher was scheduled to be the Duty Introductory Flight Pilot today.  He had a busy schedule with four visitors most of whom phoned in to check that we were flying today.

Eventually the drifting rain stopped and the sun came out.  Action DGS members! With a number of club members wanting to fly solo we readied two K-13s and two K-8s.  The third K-13, CCY, currently offline for an annual inspection was worked upon by Colin later in the day ably assisted by David Bourchier in between his hangar maintenance duties and running a taxi service for the many visitors.  Thanks both.

The rain stopped, the sun came out; Daily inspections were conducted under a low cloudbase

 At the east end the cloud base still looked low so we had to send a glider aloft to check.

So we waited a while and prepared the launch point for action later.  We waited until the Duty Instructor gave us the nod.  After consideration of the trainees on the flying list Mike Jardine shook it up and flew Toby Irons first leaving David Moorley until later in the day.

Cloud base rising; cloud definition improving

Our first visitor, Neil Black arrived with his wife, Sam, who had given Neil a two-flight voucher for his 60th Birthday.  It was reassuring to hear that despite the poor soaring weather we have experienced this summer he hadn't had to wait long to enjoy his flights with Steve Fletcher.

The weather was turning out to be quite pleasant.  The launch point bus provided a lee from the light northerly wind and it was warmer than we might have expected at the end of October. Later the site was becalmed and then the wind backed and filled in from the south (Ed; This might have been the sea breeze but fortunately it didn't seem to affect the limited soaring to be had above the site).

The promising skies encouraged the club solo pilots to take both the K-8s to the sky; Martin Broadway, David Archer (Ed:  Increasing his tally of solo flights - great to see, Dave), Malcolm Wilton-Jones, Peter Howarth, John Allan, and me for a hangar flight at the end of of the day (Ed: Well, they were running out of pilots and so had to scrape the barrel).

Promising skies to the south of the airfield
Obviously spurred on by the weather and that it was half term three-month temporary member, Elaine Morgan twisted the arm of her daughter to bring her to the club so that she could enjoy another set of wonderful views of the Devon countryside.  I had flown Elaine in August on her two trial flights but I was trumped by the Duty Instructor who flew Elaine this afternoon.

86 year-old Elaine Morgan returned to the club to benefit from her three-month's temporary membership to have some more fun and fly with the Duty Instructor (Ed: I suspect that Mike was aiming to have the widest range of ages of student in his log book 14 - 86).
The Duty Instructor thinks "Ahh!  So what are we going to do with David Moorley today?"

Moving on to our next trial flight. Terry and Kerry Neild came to the airfield from their new home in Lamerton to celebrate Terry's birthday present - a two flight voucher.   After discussion Terry magnanimously let his wife, Kerry, enjoy his Birthday present.  Enjoy it, she certainly did!
Kerry Neild all smiles while about to enjoy her unexpected flights.

Our final visitor was Trelawny Williams accompanied by his wife. In this case his better half wasn't interested in going aloft but was keen that Trelawny continued to work down his bucket list; last year a flight in a Tiger Moth, this year a flight in a glider, and next year a hot air balloon flight (Ed: What a busy man!).

What of the fourth visitor.  It turns out that due to car problems he had to cancel as he couldn't make the journey from Bristol today.  We hope that the car is repaired and he can rebook soon.

Trelawny Williams ticks another one off his bucket list" with IFP Steve
We wrapped up the day with a series of hangar landings; David Moorey and Mike following a practice low level launch failure, Peter Howarth flew the other K-13 solo with a go around practice launch failure (Ed: Following the CFI's edict for all instructors to remain current on launch failures themselves), John Allan and and I in the K-8s.

"Man of the Match" was looking like Peter Howarth with 13 minutes for most of the day, but canny Malcolm managed 16 minutes later, but on the penultimate flight of the day John Allan enjoyed some thermaling to the northwest of the airfield in an interesting meteorological feature (Ed: I was not sure if it was the edge of a front or some convergence).  When I took the last launch frustratingly I hadn't got the height to safely join him and so made use of the lift coming off the valleys to the south of the airfield in the southerly wind.  John and I landed at the same time; He 17 minutes and me a paltry 7 minutes. That notwithstanding, it was a good end of the day as we compared notes whilst dragging our K-8s in turn down the cross track to the hangar.

So today we made 30 flights.  Three visitors, three trainees/three-month members, six club members flying making solo flights in the K-8, and a ground school lecture.  Thanks to the winch drivers, especially Phil Hardwick and Andy Davey who didn't get to fly today.

Soaring at the end of October.  Who'd a thought it?

Dartmoor Gliding News - Sunday 22nd October 2023

When I arrived at the airfield there was already activity getting the ground equipment ready. A forecast for a light southerly breeze would hopefully allow a full day flying to take place.

Early morning at DGS
First to fly with me was Freddie Varley. Four flights including Freddie experiencing his first launch failure sees him progressing through his training, getting to grips with trimming, the top of the launch and stall symptoms.

Our visitor today was Sam Harrison who was with us for a one day course. Her introductory flight was flown by Steve Fletcher and further flights with Richard Roberts,
Sam and Richard ready to fly.

We also welcomed back from the high seas, Jamie Steel who was put to work and flew with Val Kiely who is making steady improvements with her general flying.

Val and Jamie all smiles.
Two previous trial flight visitors returned to make use of their three month membership. Toby Irons flew with Gavin Short getting to grips with the controls during his three flights. Robyn Golding-Piper flew with Phil Hardwick for two flights including a hangar flight.

Toby with Gavin.
Robyn with Phil.
The K8 was used by our solo pilots. Steve Fletcher, Malcolm W-J, Phil Hardwick and Jamie Steel. The longest flight was 23 minutes claimed by Steve.

Our treasurer brought a friend up to the club for a trial flight. Zhida Wang was flown around by IFP Steve Fletcher.
Zhida and Steve all smiles.
With the day getting near the end Val and Freddie enjoyed another couple of flights each. Freddie had a 22 minute flight to 1800 feet. His longest and highest flight in a glider so far. His last flight was a hangar flight where I flew the approach and landing to deliver the wing tip of the K13 into the waiting hand of Richard Roberts.

We escaped the passing showers today, but were treated to some rainbows seen from the airfield.
Rainbow over Brentor.
Plenty of Instructors, BI's and IFP to ease the load for each other today made for a good day flying and all leaving happy today. Thank you all.

Peter Howarth.
