I may be able to help re the 50 ft thing. Back in 1986, at the

tailplane from his glider, and was killed. Between us, the GFA (Mike

I've long accepted that the rule for obstacle clearance is 50'.
However, the GFA instructor handbook describes it as a wingspan,
and the B certificate oral exam calls 50' a recommended minimum,
so I'm trying to

Hi Mark,
As a general comment, making mandatory rules for obstacle clearance for
aircraft without a throttle lever seems a bit silly. If I'm faced with

Agreed! Nevertheless, my received training and my experiences at various
gliding operations
*So I *think* it's true that there's a widespread believe within GFA that
there's a rule which mandates a 50' obstacle clearance minimum, and I'm
trying to find out why :)*
If the rule called for somehting less than 50', say 5', there would be no
room left for pilots to break the rule!
