If you are there ---you should have a TPAS or TCAS or a transponder.

And I believe ATC won't allow him to fly at FL185 if that is only 500 feet
above 18,000 msl. Isn't the minimum clearance to 18,000'msl at least 1000
feet?

I think youy are right, but it depends on the sea level barometric
pressure---might be more than 1000'. But that was the altitude proposed in
the discussion.
Just to add to the discussion---some years ago, while prospecting for the
diamond at Minden, I flew several ships--6 wave flights in five
days---finally got it right! One of the ships had a 57mm Winter ALT. On the
face was the inscription "20,000 ft". The hands stopped at 24,000 ! The
vario still showed "up" so I continued. The Replogle eventually recorded
27,000 ft. The hands started moving again on the way down, after a while. I
guess the movement runs out of excursion.
