Dartmoor Gliding News-Sunday 10th April 2016

There's discretion, valour, and downright foolhardiness. And, with the Met Office issuing strong wind warnings for Sunday from Thursday on, and MeteoGroup suggesting 20 kts gusting 35, today feel into the latter category.

The scene outside the clubhouse just before this year’s AGM – 6:30 pm Sat 9 April 2016.
But just how strong was the wind at Brentor? A determined team of Sunday Soarers decided to brave the elements as far as the launchpoint at the east end to discover what our recently installed weather station was actually reading. 11.9kts. There are times when you glance down at the instrument panel and think, 'that's not right' – but you carry on flying with your eyes out of the window.

But as the launchpoint rocked on it's chassis as another gust went through, none of us could tolerate 11.9kts as a reflection of the truth. There followed a frenzy of action as Dave Downton attempted to retrieve the manufacturer's manual from the internet, whilst others adopted the 'prod first, ask questions later' approach (see photo) that comes from close acquaintance with the IT age. Eventually, via a circuitous route no-one can remember, we got the display to read in knots, and update frequently, whereupon it did, indeed, vindicate the decision not to fly, with a gust reading of 31.9kts!

And so we returned to the clubhouse, where we were treated to a presentation by Peter Howarth on (the temporarily forgotten art of) thermalling: entering, sharing and leaving of same precious commodities. Which provoked an interesting discussion, ranging from sharing thermals between gliders of different construction and Rules of the Air, to how to centre and maintain a good lookout whilst doing so. That said, it was difficult to hear Peter's presentation at times due to the wind drawing a partial vacuum through the white hot logs in the wood burner, as the wind strength continued to increase (as predicted).

In the afternoon, we continued to fettle and brief for next week's exped to the Long Mynd – hashtag #excited!
