Mmmm ...
Agreed its not a 'busy' pad ... and its not for just anybody to use (ie not public use) ... prior permission is definitely required (as well a deep pockets for fees I understand ) BUT go see the boys at HeliDubai they seem to have the approvals required ...
I've flown on to it myself .. so i know it gets used (and yes I also fly in Dubai ..
and quite frankly .. am quite happy to avoid the place and its associated restricted area).
Cheers ....
