helicopters, by principle, can land on an awful lot of places, shall we tag
all of them as helipads? I must admit I find it strange that a hospital
with frequent landings of helicopters doesn't have a dedicated signed
helipad (neither FATO nor TLOF, nor safety areas(1), right? No floodlights
or signal lights for night operation either?), but if this is typical in
some places (or exceptionally occuring) we might consider to tag such
places as helipads anyway. I've researched this a bit (but am not an expert
in the field), and according to ICAO, Annex 14 Vol 2, 3.1.1, "a surface
level heliport shall be provided with at least one final approach and
take-off area (FATO)." and 3.1.13 "At least one TLOF shall be provided at a
heliport." As this is a document about aerodromes, it focuses on heliports
and doesn't provide a definition for helipad, unfortunately. I believe we
can agree that areas like the one you described, should not be mapped as
heliports. If someone can come up with an official definition for a helipad
that would be appreciated.


Cheers,
Martin

(1) FATO=Final approach and take-off area
TLOF= Touchdown and liftoff area

btw., I've just found these standards documentation for aerodromes which
might be interesting for other mappers as well:
