Friday 26th June - Le Mistral

Standard protocol whilst flying in the southern French Alps is to use the thermals generated by the sun facing slopes. The anabatic winds created by this rising air causes a valley breeze strong enough so that the south facing ridges also work dynamically. A light northerly gradient wind interferes with the valley breeze and can make conditions really tricky requiring a more analytical approach to choosing where to look for lift. If this north westerly gradient wind gets even stronger it is known as Le Mistral by the locals. When the Mistral blows it overpowers the valley breeze and chops the thermals to bits but it also opens up a variety of new ridges that can be flown dynamically and linked together to create XC ridge flights to the areas where the wave is best. 

The winch launch into the NW wind is lively and the winch driver invariably calls for ‘corrige route’ (correct towards the road!) and the pilots call for more or less speed as the glider climbs through the rotor. It sounds scary but it’s soon over and you head for the ‘ravine’ which is a large NW facing gully on the lower levels of Blachere, the mountain by the air strip that propels you skywards as you start a series of ‘eights’ to maximise the lift before switching to circles as the mountain top is reached.

1450m and you jump 3k to a west facing rock face of Jouerre that climbs from 1300 to 1890m in about 1km. You join the ridge just above the top and as you follow it you climb, faster than the ridge climbs, and at the top head west 3km to a pair of vertical west facing rock faces nicknamed the Camel because from the airfield it just looks like a couple of humps. Don’t stop here, just turn south and run the ridges to the Gache – a massive and very well known north facing, ochre coloured escarpment that just ‘goes like a train!’ You can stop there and climb high, just soaking up the views to the north in the crystal clear air before heading west over Sisteron town in search of the wave.
Getting into the wave usually involves tight turns in rotor thermals that are humongusly rough; Dave Rilley once described flying the rotor thermals in Cerdanya as like wrestling with an Alligator. Well the alpine Alligators are just as energetic as their Spanish cousins and just as reluctant to let you get into the wave without having a bit of sport with you on the way!! Although once established well worth the struggle, the air becomes silky smooth with off the clock climbs. During the week the team managed to climb to just beneath the airspace at FL195 the local ceiling at Pic de Burre from where they could glide into the higher mountains sightseeing and collecting OLC distance points before returning to La Motte. The views from that height are just breath taking, the Mistral brings with it crystal clear air and Mont Blanc and the Matterhorn dominate the distant skyline. Boring…. Time for tea.
