Dartmoor Gliding News-Wednesday 20th January 2016

A change in the weather today was bound to generate plenty of excitement at the airfield. It was dry, cold and the wind was forecast to be from the SE. Regular readers will know that, at Dartmoor Gliding, any wind with east in it brings with it the chance of lee wave.

Arriving at the airfield, there was already plenty of activity. Unfortunately in their hurry, K13 G-CHXP had it’s main wheel tyre valve torn out, making the aircraft un-serviceable. Jorg and Dave set about changing out the damaged inner tube. Normally this would take about half an hour. Yes, I know that an F! car gets 4 new wheels in under 3 seconds. But due to a comedy of errors / unfortunate coincidences, which would have served well as the basis of a script for Charlie Chaplin, it was nearly 2 hours before the aircraft was ready to fly.

Meanwhile, flying continued with a mixture of check flights, Instructor and pre-solo training. Was there wave? Well no. There were all the signs, lots of rotor turbulence, cloud appearing and disappearing, areas of heavy sinking air and a few challenging approaches, but no smooth wave lift. Looking at the temperature profiles this could have been predicted. The wind speed was not increasing with height. The inversion was a bit higher than would be best but other wise the airmass looked stable. The wind direction above the inversion reversed 180 degrees to become westerly!! Better luck next time chaps, but the practice in the rotors will stand you in good stead.
Wednesday's 12pm sounding
We welcomed visitors Eric Underwood and his wife. They had arrived just to find out where we were but as conditions were flyable and Eric had brought his voucher with him he enjoyed a couple of flights with instructor Ged Nevisky.

Eric is ready for his air experience flight picture here with his wife.
It remained cold all day with every one wrapped up in their own brand of cold weather clothing. By early evening we had completed 31 flights, not a bad total but lowered a bit by the late arrival of HXP.

Thanks today to all who helped out as ground crew and to Jorg and Dave for the marathon wheel change.
