Rules for JOINING IN with others in a thermal.
- The glider already circling in the thermal has the right to continue circling.
- Turn in the same direction as the other glider.
- If there is only one other glider present you may offset your circle, but you must turn "in phase" with the other glider.
- When there is more than one other wing, you MUST be concentric with the other wings.
- Time the entry so as not to interfere with the other wing(s).
