Problem is sometimes jumps are done impromptu and no NOTAMS filed. In

ok, but DZ are published, right? at least on the charts, even
if the time of activity might not be NOTAMed? I still don't think
that just listening to the radio might be a sufficient substitute to
a good pre-flight planning... (I mean, you have to know what to look
for)
