FFF,
Thanks for your input... i hold bot licenses and agree that when flying gliders in genral, this is not usually done in a straight line or track but when flying cross country, gliders or often on track maintaining heading and i have on numerous ocassions completed task with an average indicated airspeed of 120kts... bear in mind this is fasters than most c-152 cruise so i would expect Glider pilots to get as much info regarding other A/c that may affect thier flight. I do. thanks for your feedback any way.
