Glider pilots in contest carry parachutes so in most cases I can think
of it would be better to have the ELT with the pilot. Is there a reason
this is not allowed in contest flying?


It's probably because the ELT that's carried in a parachute won't activate on
impact like the one mounted in the aircraft. If an aircraft crashes and the
pilot is incapacitated, can't reach to activate it or worse yet, dead, he might
as well not even have one. The ideal situation would be to have one mounted in
the glider and one carried in the parachute.
