Thermal Task Setting

This page is based on the task setting tutorials prepared by Liz Sparrow and Mark Davenport for the Apprentice Tasksetters for WWGC 2022, which is being held at Husbands Bosworth.

The various files are zipped up as they are quite large.

Planning a Task

Overview of Task Setting

As always, the slides for the initial presentation are not as instructive as listening to it was. However the task setting 'method' comes down to:

  1. Decide how fast one will fly, given the weather, glider and past performance;
  2. Look at the weather to determine when soaring will start and finish;
  3. From the two items above, work out how far one can fly. If, for example, it works out at 320km, setting a 300kmm task gives a little wriggle room;
  4. Check notams, also see if the weather indicates that one area will die early - if it does, go there first;
  5. Other points to consider:
    1. Remember that up & down-wind legs fly better than cross wind legs;
    2. Geology can have a bearing. Around Moreton-in-Marsh thermals won't work as well as Stow-on-the-Wold. The Cotswolds, Downs, Chilterns & Lincolnshire & Yorkshire Wolds are all free-draining, so they dry quickly and warm faster than low flat ground that holds water. Warmth = thermals. :)
    3. As well as the bedrock, the Cotswold Edge and similar ridges can generate hill lift;
    4. Towns, car parks, warehouses & so on are good thermal generators;
    5. We are advised to avoid VRPs;
  6. Plan a task taking all the above into account!
