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.<br><br><br></div><div class="gmail_extra">Cheers,<br></div><div class="gmail_extra">Martin<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">(1) FATO=Final approach and take-off area<br></div><div class="gmail_extra">TLOF= Touchdown and liftoff area<br><br></div><div class="gmail_extra">btw., I've just found these standards documentation for aerodromes which might be interesting for other mappers as well:<br><a href="https://drive.google.com/file/d/0B2u8czVndcm6ckVKZ1RsYUtoT1U/edit">https://drive.google.com/file/d/0B2u8czVndcm6ckVKZ1RsYUtoT1U/edit</a> (Vol 1, aerodromes)<br><br><a href="http://dcaa.trafikstyrelsen.dk:8000/icaodocs/Annex%2014%20-%20Aerodromes/Annex%2014%20Volume%202,%20Helipors%20-%20Edition%20no%203.PDF">http://dcaa.trafikstyrelsen.dk:8000/icaodocs/Annex%2014%20-%20Aerodromes/Annex%2014%20Volume%202,%20Helipors%20-%20Edition%20no%203.PDF</a> (Vol. 2, Helicopters, is from 2009 and might be old)<br><br><br><br>
