yes, those are travel-related.
in other words, they will evacuate you or a family member by air due to any
medical emergency IF you are at least 50 miles from home.
what i mean is, where does it say that they won't pay for a helicopter lift from
a dive accident to a hospital if less than 50 miles from home?
that, by the way, is part of the DAN membership benefits. you don't have to
purchase the DAN insurance to receive it.
the DAN insurance is different. that provides for coverage for a diving
accident. I don't see anywhere that the coverage for a diving accident
is limited to over 50 miles from home.
check out page 25-26 of the insurance guide:

3. Ambulance charges for transportation by a professional air, ground,
or marine ambulance to the nearest hospital or hyperbaric chamber where
appropriate care or treatment can be given.
and it doesn't give a minimum distance.
it does make two provisions:
a. Doesn't cover charges covered by the Travel-Plan (the one with the
50 mile minimum); and
b. Transportation by air or sea ambulance has to be pre-arranged
by DAN Travel Assist.
