Dartmoor Gilding News - Wednesday 4 December 2024

This morning dawned clear and dry.  The roads were dry too with no streams of running water throwing up spray which has been a continuous feature of late.  It was colder which  inevitably triggered snowflakes, on the dashboard, as the temperature dropped to 4C in the valleys.  There was a touch of radiation fog present but it was a very pleasant morning to drive to the club.

I arrived to see two souls returning from a pitch inspection, then testing the light airs for direction with a handkerchief, before taking a decision, getting the winch out, and setting it up at the west end.

The forecast was for the wind to fill in from the south and veer as it freshened before the expected rain mid afternoon.  The Wednesday Wavers had the site to themselves with the three Navy Fliers from HMS Audacious having to cancel at short notice as they were required onboard their submarine.  Such are the exigencies of the service.  So Phil's services as a Basic Instructor would not be required today.
 
So the early birds got the rest of kit out, but not the gliders, whilst waiting for the Duty Instructor, Mike Jardine, to arrive who too would also be under utilised today with no trainees present.

Mike's arrival allows the two instructors to discuss what to do today
Once we got the kit out inevitably the cloud filled in, as forecast.  The cloud base was definitely too low for flight operations.  Would we fly today?  Time for tea and a think.

Time for Operation T-21.  Move the T-21 to the east end to free up much needed space in the glider rack.  To be able to move the T-21 in its trailer the glider had to be first removed from the trailer.  This would allow access to bolt the replacement second axle to the trailer to make it fully mobile.
 
Door open.  The instructors lead from the front.
Once the trestles, tail plane, and ailerons (already detached) were removed the fuselage could see daylight
Peter checks the Daily Inspection book.  It was last prepared for flight on 22 May 2004 by erstwhile glider pilot Trevor Taylor.

Following my instrumentation lecture; a question for our juniors.  Which is the Pitot probe and which is the Total Energy probe, and how can you tell?  The first to answer correctly can pick the chocolate bar of their choice from the tea swindle!
Part one of the operation was successful.  However when the trailer was out of the rack it was obvious that there was a problem.  One side of the A-frame was no longer connected to the trailer.  Plan B was enacted.  The glider was returned to its trailer and the trailer was parked by the clubhouse to allow it to be worked on.

The pundits admire the simplicity of the instrument panel.  From right to left; altimeter, ASI, COSIM variometer and mechanical variometer, the latter is equipped with a MacCready ring (to indicate the speed to fly when in the cruise!)
The mighty COSIM Variometer.  Glider instrumentation at the pinnacle of excellence.
How the COSIM works.  Green ball up - Good.  Red Ball up - Bad!
Meanwhile, Mike admires
the delicate lattice work of the restored rudder.
Trailer assessment complete.  It's time for the fuselage to go back in its box.
When safely parked Colin then left the site to talk to his welder friend and procure some suitable steel to effect a repair.
Operation T-21 (partially) complete.  Thanks to the vintage glider crew (take that epithet as you see fit).
I had hoped that by shuffling some trailers there would be two empty slots freed up for members who need to park their glider trailers in the rack.  Unfortunately, despite much measuring by John, Dave, and I we couldn't make it work.  There is a longer-term possibility of clearing some gorse and flattening the bank to allow more space.

So Sean, after a long and patient wait, can move his Libelle into the slot that was occupied by the T-21. 

John Osmet with his new Standard Cirrus (congratulations!) will bring his trailer on site soon, so a further slot needs to be found.

Around the T-21 activity other work was progressing in the hangar and clubhouse.  But after the main event was complete the Wavers started to disappear.  When I left at 1430 the forecast rain was just starting So I left John and Dave to their in depth conversation.

In the clubhouse Gavin discovers the rattle in his aircrew instrument (which provides a display of Flarm and ASD-B tracks, a fluxgate compass, and a solid state artificial horizon); a loose heat sink.  It's now secured back in place (see top left).
An update: The Met Office named Storm Darragh on Thursday 5 December and its due to roll in at the weekend bringing much rain and strong winds.  So we can look forward to plenty of ground work and maintenance on Saturday and Sunday, with a very blowy committee meeting on Saturday afternoon.

Dartmoor Gliding News - Saturday 30th November 2024

The problem today was the weather once again. Cloudbase was 420ft above sea level. As the airfield is 820 ft above sea level we were in cloud ( fog ) all day. This only lifted occasionally to allow it to rain properly.

The clubhouse was busy once again. Today's work programme saw the Puchacz project continuing, The tractors washed and the Main Generator serviced. The backup generator started well and provided an slightly restricted electrical supply all day: we could only boil one kettle at a time; definitely a first world problem. I am sure that I missed lots of other work going on. Everyone seemed busy.

A usual, there were a couple of lectures today. Winch launching with Rick Wiles and the Instrumentation with Gavin Short. If you add to this some simulator flying, tea and lunch breaks it was a busy, busy day.

Thank you everyone for your efforts and good humour.

Storm Bert is with us giving torrential rain and a howling wind. The water is running off the airfield in torrents. So, the airfield was quiet was it? Well no. the clubhouse was busy.

Rick's gang ( trainees) were here. They undertook a series of lectures and simulator sessions as well as getting the mower down from the field, removing the mower decks, cleaning and storing them in the hangar for the winter. 

And the next lecture ... Spinning and Spiral Dives
Rick with Zak. Ready to launch

Several other members were here. Gavin was deep into the Puchacz paperwork as well as collating all the details for the upcoming works and CofA. Adam was working around the aircraft. John worked on the simulator controls. David and I made a new lead seat cushion for the K8 preparing for when the juniors are ready to fly it. Scratch was in MT hangar keeping vehicles and winches on line. I am sure there are other tasks that I have missed but you get the idea. DGS was busy.

The track and apron became a river
By the time we left it was dark again and if anything the storm was even more severe. Those balmy, summer soaring days seem so long ago

It's getting colder at DGS.  The polar air has arrived on a north westerly air flow.  Frozen sleet had fallen overnight.  Time to adopt winter gliding garb.  The hangar apron's resplendent golden brown covering of beech leaves had been damped down by the sleet, its hues subdued.  New yard brooms arrived the club ready to clear the apron.

No visitors were booked to fly with the Wednesday Wavers today so we had the club to ourselves.  With the juniors at school there would be no more first solos today either.  So the Duty Instructor, Mike Jardine and I, as the Duty BI, felt a little redundant at the start of the day.  But there was flying to be done and, some slightly older, trainees to fly.

Val arrived at the club which was bathed in bright sunshine but then things started to change.

We headed to the East end with a single K-13 and K-8, mindful of the soft ground.  We then headed back to the clubhouse, and the wood burner, ready for the morning brief.

What of the weather for the day?  To paraphrase our late Queen "Forecasts may vary".  So the Wednesday Wavers would have to make he most of what mother nature presented us.

However, this shows the reality, and the wetness of the ground, at the east end
I had long thought that the Icelandic and Inuit languages had the most words for snow but having heard Alasdair describe the onset of the drizzle on Saturday afternoon in Scottish (Gaelic for the pedants) I wondered.

Apparently there 421 Scottish words for, or related to snow. I am sure that Alasdair can enlighten us with some more when he is next at the club but in the meantime I have worked some into the blog.

K-8, GDK is ready to go.  What are the Wednesday Wavers waiting for?
The skies darken heralding the sneesl (to begin to rain or snow)
We experienced a flindrikin (a slight snow shower) at the launch point
The view towards Mary Tavy became distinctly dreich
(weather that makes outside look grey, dull, gloomy and very uninviting)
The snawie (snowy) launch point.
With that the launch point crew decided to head back to the clubhouse as the snow started to feefle (to swirl) whilst we were driving down the centre track.  To stop us misting up Geoff drove with the window open so we received some skovins (large snowflakes) inside the cab.  From the passenger seat I switched on the fans, heater, and the heated seats on instead!

Radioing the winch produced no response.  Robin had already abandoned his cab and had wisely headed back to the club house.

Just as the Wavers were getting comfortable and warm the Duty Instructor cleared the clubhouse as the flukra (snow falling in large flakes) had abruptly ceased.  It was time to go flying.

Heading back to the launch point the Duty Instructor encounters
 two deer crossing the runway.  Can you spot them?

We welcomed Steve Raine, our previous long-serving treasurer, to the launch point who was happy to observe the proceedings.

Then came the unbrak (the beginning of a thaw)
The flying started with Geoff experiencing an aborted take off (the winch engine was cold!) and then on the next flight the effects of the controls near the stall which he found to be quite enlightening.

The snaw (snow) cleared at the launch point.

The same routine was carried out with the K-8 with flights by Mike Bennett, Hugh, Gavin, Andy, John Allan, Dave Archer, Peter, Phil, and Scratch before staring the cycle again.  There were some snippets of lift on the ridge but several of us concentrated on spot landing on the stub.  Dave successfully made his first landing on the stub in the K-8. Congratulations.

In the early afternoon is was quite warm in the sun.  I had to take off my woolly had whilst in the tower!

There was glush (melting snow) on the south-facing slopes to the north during the afternoon
Andy readies himself for the final flight of the day in GDK
After Andy's hangar landing the toys were packed away very smartly.  It was pleasant doing so in daylight.  We must thank DB for his efforts who emerged from the hangar, as we returned the gliders, after working there all day.

After the flight log had been produced (24 flights) we headed home after an unexpected almost full day of flying.
