Dartmoor Gliding News - Christmas Eve - Sunday 24 December 2023

Another gloomy and wet forecast, with a low cloud base, caused the Duty Instructor to cancel flying at Brentor today.  But there has been activity at the club recently in anticipation of the big day by the DGS Maintenance Team.  Here is their latest fleet update:

As spotted last year (Ed: By the number of reindeer fog must have been forecast)

DGS Fleet update - Sunday 24 December 2023

Santa Sleigh - G-HOHO - Serviceable

Annual inspection completed, ARC issued, BGA and CAA informed.

Reindeer droppings and stray Bourbon biscuits vacuumed out of the the cockpit.

Repairs have been effected to the existing landing damage to the LH side of the cockpit with fresh 1.5mm aviation grade plywood using Aerodux glue. Repainted with Cirrus Red paint (RAL 3000).  New CAA registration letters applied as required.

Damage to the left skid has been repaired by fitting a new skid.  The pilot was informed to attempt landings on grass in preference to landing on concrete or rough terrain.

The TOST Aero tow hook was exchanged to cure the reported tardy release on demand.

The ASI and Altimeter have been checked against Colin's electronic manometer.

 

PowerFLARM Fusion Firmware version 7.22 has been installed and checked against the club's Atom base station so members can monitor the flights on Glide and Seek or Flight Radar 24.  Accordingly, the Stealth/competition mode has not been selected.

Ventilation holes were drilled in the front screen and a vent deflector was fitted following the misting problems reported last year.  This was another good vent deflector installation by John Smith.

Traces and reins inspected and assessed as serviceable for another year following DB's servicing of the eight reindeer tow ropes and checking of their weak links.  A ninth has been produced for Rudolf as a contingency if fog is forecast on the flight plan.  The fifth strap on the safety harness has been removed as aerobatics are no longer permitted due to the CFI's local ruling.

Mrs Bennett has made new safety cushion covers incorporating Navboy's latest air foam safety cushions (Ed:  These retain their energy absorption characteristics even in extreme cold unlike Confor or Dynafoam.)  A new, large cockpit pocket has been fitted for in-flight essentials and has a low-noise USB charging port.

The tatty yaw string has been replaced by an MK IV “high tech” Yaw String courtesy of John Allan.  It was procured from Navboys before their move "Up north" from their previous base at Lasham.

Hugh Gascoyne worked on the air brake caps, fettling, and touching up the paint to ensure no air brake cap "chatter" at high speed.  Air brake over-centre-lock pull-off force checked correct.

Weight and Balance calculations were reviewed by the Chairman and the Fleet Manager.  The British Gliding  Association 3% all-up weight concession was correctly applied which has increased the luggage payload by a useful 21.2 Kg. The placard has been reissued accordingly

Operation of the 8.33 kHz spacing radio checked correct. David Archer has also checked the antenna with the Voltage Standing Wave Ratio meter and it's within tolerance. Oxygen equipment was removed to reduce weight as no wave flying is expected this year.

The glider log book has been updated and the sleigh released to service.  Adam has added a new aircraft type to his Personal Experience Record which should help him on his path to get his BGA Inspector's ticket.

Merry Christmas and Happy New Year,

from the DGS Maintenance Team

Dartmoor Gliding News - Wednesday 6 December 2023

Due to no visitors today, caused by a cancellation by naval personnel due to the exigencies of the service, and no other visitors, no trainees either, the Wednesday Wavers had the club to ourselves.

Mike Jardine gave the weather and morning brief; fairly calm, overcast with the wind from the south east building gently during the day followed rain by the time it was dark.  After a few admin notices Peter, prophetically, mentioned that the Puchacz flight manual listed crosswind limits which might curtail flying during the afternoon if the wind strengthened.

Before its daily inspection the placard in the Astir CS77 was treated to Dynotape labels with the min and max pilot loads in Kgs and the dual-knotted yaw string reduced to a more manageable (Ed: And sensitive) single length of red wool.

The Astir CS77 after its Daily Inspection (Ed: Note shiny red tail dolly)

Daily inspections completed a K-13, FGR, and the Puchacz were taken to the west end.  The field was still "moist" but flyable (Ed: To be honest it was boggy in many parts).  If the conditions were OK for solo flying the K-8 and Astir CS 77 were to follow up to the launch point.

Trailer park fettling (Ed: And boy do these K-6s need a lot of fettling!)

Up on the field the wind was freshening remarkably quickly from the south east ahead of the forecast.  Mike and Peter took the first launch of what was planned to be a series of flights to convert Mike to the Puchacz.  Inevitably these would include a practice launch failure.  The launch was surprisingly turbulent and continued up to two-thirds of launch height when our first red link broke with the Puchacz (Ed: As its designed to do) in what seemed like rotor, but may have been caused by extended curl over from the trees on the south side and an extreme wind gradient.  As Mike turned the glider the upper wind was surprisingly strong and caused significant drift downwind before the intrepid duo landed after a modified circuit (Ed: So type conversion and launch failure practice all in a single two minute flight.  How economical is that?)

After considering the conditions, which were going to be challenging for a K-13 too, Mike decided to stop flying operations.  Meanwhile the wind strength was increasing further.  So the launch point was packed up and the two two-seaters, and the winch brought were back to the clubhouse.

The Puchacz suitably chocked after its short flight

The early cessation of flying meant that we were able derig FGR ready for its annual inspection.  Once suitably mounted on the "dead man" frame the canopy was removed, the tail plane disconnected, the seats unscrewed, and  the wings removed relatively easily using the "Allan" main pin retractor.  A few modifications in size and shape and the "Allan" retractor will be suitable for both lower and upper main pins for our K-13s.  The wings were placed on trestles on the right side of the hangar and CCY's other wing laid ready for inspection.  The fuselage was initially place on the left side of the hangar.

A committee of taste (Ed: That's a highfalutin name for you and Peter contemplating life on the hangar apron) considered that the Puchacz wouldn't fit and that FGR's fuselage needed to be placed along the back wall behind FSD in hangar position one. Positioning the various components parts and location of the gliders when we packed the hangar required some in depth thought.  So with the tea made all retired to the clubhouse for lunch and some sinking thinking (Ed: "This is the German Coastguard what are you thinking about?").

FGR being derigged for its annual inspection

Suitably refreshed after tea and lunch the hangar was packed in double quick time. Some minor projects were progressed and the Astir CS77's documentation was weeded and filed.

After lunch Jamie Steel came up to fly (Ed: But yet again we weren't due to the weather) so he discussed with me the arrangements for our navy flying package in the New Year.

Andy Davey brought two belly dollies to the club today and we trial fitted to the Puchacz The better fitting will be loaned to the club and will be used for fitting out our AMF trailer (Ed: Thank's Andy).

Andy's long term loan to the club (Ed: I can see the need for some red paint on the horizon)

As the afternoon drew to a close  (Ed: Sunset at Brentor was at 1613 today) and we started locking up Jamie was presented with a raspberry-jam filled doughnut as compensation (Ed: That's one way of ensuring that we don't attract any mice into the clubhouse) for not being able to fly with this autumn.

Today the Wednesday Wavers were thwarted but not downbeat.  "We will get to fly. We will get to fly." Repeat after me. "We will get to fly."

Dartmoor Gliding News - Saturday 2nd December 2023

Luck seems to be on our side with a weak ridge of high pressure giving a "quiet" spell weather. The forecast was for light variable winds with a southerly drift initially, gradually strengthening and backing to the SE. The blue sky was gradually obscured by high cirrus until late afternoon when the next  made an appearance with solid cloud cover. It was cold all day.

We had 2 visitors today. David Baker flew with me and Katherine Steer flew with Phill Hardwick.

The Puchacz was kept busy with instructor familiarisation flights. This and some check flights meant that it was a day with a lot of practice launch failures. The southerly breeze turned this into a day with a lot of cables landing over the northerly fence. A special mention and thanks must be due to the winch drivers who took this all in their stride. This and the change of ends early afternoon somewhat suppressed the launch rate.

The Puchacz was kept busy

The view south was somewhat ethereal with the sun shining on the sea

The Astir CS77 was kept busy as the solo pilots were trying out this "new to us" glider.

A bonus flying day.

Dartmoor Gliding News - Sunday 3rd December 2023

The Sunday rain, low cloud and wind was due to continue according to the forecast. The small turn out settled in the clubhouse with teas and coffees with the log burner lit for chats and putting the world to rights. Usually ever optimistic Richard arrived and presented us with bacon and bread, so we set about making butties for a late breakfast. Saffron loaf and butter was provided by Sean. Junior member Toby Irons arrived with dad Howard so we gave Toby his joining pack and started working through some ground schooling.

Richard came back into the clubhouse and said to me that I should look outside as the weather was not acting like the forecast. Having looked at the sky and the surrounding area, I decided we should at least try to fly. The airfield was quickly set up and one K13 was taken to the east end launch point.

First launch was Sean Westrope who hadn't flown for seven weeks due to the continuous string of bad weather on Sundays.

Sean happy to be flying again.

At the top of the launch we could see a band of rain down in Cornwall. After landing and doing checks ready for a second flight, the rain arrived so we headed to the bus and waited. A break for an hour saw a clearance finally arrive, so Toby Irons was given the next chance to fly.

Toby ready to go flying.

We managed three flights practicing turns and learning about trimming and stall warnings.

Off we go into an overcast sky.

Toby watched by Dad Howard getting ready again.

Next into the K13 was Ed Borlase who also hadn't flown for seven weeks. At the top of the launch we saw another heavier band of rain heading our way. A radio call to the launch notified them we would hangar land and be packing up for the day.

A day that started with a forecast of no flying, ended with a junior member happy with his flying and two other members just glad to have flown after a long spell of no flying. Thank you to those who were at the airfield including Gavin and Richard who did not manage to fly. Never say never.
