I'm a very experienced power pilot CFI & have soloed hundreds of airplane student pilots over the years. That said, I'm not as experienced as a CFIG.

I soloed a new student this weekend. He flew three solo flights & did a spectacular job. He has no former flying experience so he wasn't the typical add-on pilot that I'm usually teaching.

On line it appears in several places that the average time to solo a glider is around 40 flights. Is they information accurate? My student doesn't have nearly that many flights.

Opinions?
I soloed on my 20th flight with zero previous flying experience. Credit this to having 3 to 4 flights a day for 6 flying days over a 5 week period.
