Recent flying at Talgarth
Sunday 14 May 2017
The forecast was for an unstable SW airstream with possible showers, drying out as the day progressed. There were only a dozen or so intrepid aviators at briefing with a few people away elsewhere. The SW ridges were working well with dynamic lift and thermal to a base of about 4000' QNH initially.

Unexpected wave to 7200
RASP indicated that wave was unlikely: No inversion (actually quite a high lapse rate) and wind veering markedly with height. However after morning tea (how civilised!) our eagle-eyed tug pilot Tony Crowden spotted an edge in the clouds in the lee of the Black Mountains overhead the Wye Valley. So off we went in search of it. After a lively tow through the rotor we eventually found 4 knots of the smooth stuff. All the way up to 7,200 feet. Running from Hay , past site and all the way down the Cwmdu Valley. A nice surprise for a trial lesson and Ray Smith who also joined me in K13. What a fabulous site we fly from.

Another great day out!
Lovely warm weather with little wind - now that doesn't sound like Tal does it? Heavy inversion at first meant very poor viz and weak thermals to about 3500 amsl with only small haze caps. We'd set a task to New town, Llandeilo and back for 200km but it soon became clear this was maybe a little ambitious. Nevertheless yours truly decided to give it a go and was soon regretting this as I scrabbled around too low for comfort near Hundred House where landing options were limited!

A great day out...
I'll have to give this report from my perspective because I was in the air for nearly 6 hrs and so don't really know what else was going on.
We set ourselves one of the club tasks (see the ladder for the whole list) of Llandeilo -Mynd and back for a 224 km triangle.
Oh nearly forgot to say congrats to Dave Hope as he was the only one to get around the original task.
Yes it was a lovely day - summer is here!
I went quite high and slow all day - it probably paid off.
I'm sure we don't use the local convergence patterns enough. It was predicted by RASP - just click on the 'BL Max. Up/Down (convergence)' button for about 2pm on any sunny day with light winds.

NE wave 9000 ft
The forecast brisk NE wind made conditions on the field a bit sporting!!! During the morning, Cu bubbled up nicely with no sign of the cursed wave - Hoorah! The forecast also predicted cloud increase by Midday. I took the second launch onto Troed in my recently returned, refinished and fettled Nimbus. The ridge was working well and the thermal climbs were vigorous. My plan was to push up wind to Hay Bluff and to use the Pandy ridge, but that wasn't possible on the first attempt so I dropped back on to Troed. And lo, the sky changed, the Cu disappeared and the wave set up, curses.
A broken climb to 6000ft and the sky changed again with a sudden build up of cloud, I spiralled down through a closing gap - no drama - just being cautious. Once below cloud base I had enough height to reach Hay Bluff, the Cats Back was working well but I felt that the wind needed to be more Easterly for the Pandy ridge to work - no problem to reach Hatterall Hill, but getting back might be an issue. On the other hand, reaching the Blorenge would be a breeze (down wind) then the Llangattock ridge would get me back to the Cwm Du or onto the Beacons.
And so it came to pass, on returning to the Cwm Du, the sky had opened up again, the wave was better organised and I climbed to 9000ft. The wind decreased above 8000ft and so did the climb rate, there were good looking wave bars to the North but nothing went as high as in the Cwm Du.

ice and stuff ...!
A fun day at the club with 10kt northerly and lots of big clouds some of which were dumping ice and stuff down to ground level. Crystal clear visibility with 6/7 knot climbs tempted a few to attempt the Mynd but in the end it was too showery up there. Mike Codd was clearly an aiming point for the USAF when a couple of heavy jets came far too close on the main ridge... an airprox is being filed by Mike. Quite a few out playing today,,,,
Monday 24 April 2017
Turning up in the morning with the cloud halfway down the hill, drizzle in the air and a cold front on the way -- didn't look very promising we would be getting airborne. The tug pilot decided to go home after a couple of hours of watching cloud base descending.
Come 15:00 the conditions started to improve, I wanted to rig but no tug pilot! a quick call to TC solved that problem. 16:00 I had a launch followed by Mike Codd in his Ventus. The main ridge was working nicely and it was relatively easy to find an energy line and go exploring. As the airmass dried out and became a lot more stable there were definitely signs of wave. I was surprised when I contacted wave over Y-das, though unfortunately the sun was sinking faster than I was rising, so couldn't get a ladder flight and had to break off whilst climbing at 2 kts, landing at 20:00 (at least I could derig in the light).
A really enjoyable evening flight and both of us getting some wave. Thanks to Tony who came up to give us a launch.

First good day of the year - wave to 7000ft
Ground is a bit soft but drying out fast. First good day of the year and nearly 4hrs cruising up and down the ridges with some lovely mellow thermals and then a wee bit of wave to 7000ft - the season has started so get up there and get some in ! :)
Those out incl Tony B, Tony C, Tony P, Anne C, Mike R, Andy Sutton and a visitor from Usk. Mike Codd did the briefing and instructional flights whilst Keith and Tony C shared the tugging. John and Edna Horley made a welcome visit.
Meanwhile the bore hole is pumping water out at a substantial rate whilst the plumber completes the installations.
