[Tagging] informal helipads for emergency use

[Richard Welty]

i'm talking to a volunteer firefighter about various emergency issues. 
one he brought up that
i'd not thought about before is what they call landing zones.

in rural areas, these are predetermined locations for helicopters to set 
down to airlift out
urgent medical cases. they are not generally "official helipads", just 
level grassy areas where
they have arrangements with the landowner.  generally they also have 
agreed upon names.

i'm thinking both areas and nodes, with tagging that looks something 
like this:

aeroway=helipad
name=Fred's LZ
access=no
emergency=yes
surface=grass

does this seem reasonable?

thanks,
