It is sometimes difficult to interpret whether helipads can in fact meet ICAO standards.Take a look at the current disasterous proposals to site a new helipad in the main public area next to patients (65 ft from a ward) outside Frimley Park hospital outside...
Tell me what you think?
Would you land at first floor level on a narrow pad,next to the main ward (waking them all up three times a night )to a busy hospital at 3am in the morning,mid winter,with wind sheer, rain, close to heavy concentrations of people with no lighting?
