Winged Shadow Systems Thermal Scout

摘要

This tiny device uses a novel method to indicate thermals. When a glider is rising in lifting air, the Thermal Scout will wave the rudder from side to side. This produces a distinctive movement that is easily seen from the ground. The pilot then switches the unit off and circles in the thermal. At any time, the pilot can briefly switch the unit back on to test if the plane is still in lift (as indicated by immediate rudder movement). A series of such tests can be used to scout out the boundaries of a thermal.
