Roger Posted July 20, 2013 Author Report Share Posted July 20, 2013 Hi I operate a Pipstrell Virus (41 wingspan) out of Placerville, CA and Canby Oregon. Great motorglider plenty fast 120 kts. Question, when thermaling, the manul suggest 49 kts and one notch of flaps. My understanding is that may reduce the glide ratio but may improve the minimum sink rate, has anyone used flaps when thermaling, and what was the performance?Pipistrell Virus N282TT Quote Link to comment Share on other sites More sharing options...

Rand Posted June 30, 2015 Report Share Posted June 30, 2015 Roger - sorry for the late response - hard to measure best glide and min sink, but I think the rationale for flaps in thermal is to reduce stall speed enabling tighter turns in the narrow column thermals. rand Quote Link to comment Share on other sites More sharing options...
