The FAI rules will also clarify flight recorder etc. requirements. It

usually easier to fly with an IGC recorder but it is for example it is
entirely possible to do a straight out silver distance with no

of any type (the tow pilot attests to the release altitude and the
finish altitude is the landing elevation).

Geez which twit wrote this? What I should have said is it's possible to
do the silver distance without a flight or position recorder - but that
still needs a barograph for proving flight continuity. The duration
flight can be done with just OO observation. Maybe to my point that
trying to simplify/explain these rule scan be dangerous and you really
need to study the actual rules.
