Turn coordinator? How dare they!

Short answer, big sky, little (and very few) bullets in cloud.

PCAS can also be used.

So can radio to ATC when appropriate.

I have read that UK and USA airspace is different, so please excuse me if I tell you what you already know.

Most glider cloud climbing is on good thermal days with isolated cu, typically cloud base 4000’ or more, and in class G which covers most of the country. On such days, in class G, almost all GA (power) keeps well below cloud. Those that go as high as the cu tend to go round them, to avoid turbulence (i.e. our lift). Some go above the clouds, where we can’t get.

One area I use for cloud climbing is near a military complex. I often call them to see if they have traffic at cloud levels near me (never have yet) before switching to glider cloud flying frequency. And I have PCAS (as well as Flarm).

There have been only 5 UK collisions between gliders and unrelated power since 1970. 3 were in gliding circuit areas, the other 2 well below cloud base in good VMC. (Both the latter were power flying into the glider – one from behind, the other from below when aerobatting.) Airprox data also show all glider/power incidents in VMC and usually well away from clouds.

There have been far more glider/glider collisions – and we all take that risk, albeit mitigating as best we can. But that is another story.
