Emirates do not treat YPPH as an Isolated Airfield and do not recognise the term " Island Holding " or " Isolated Reserves". YPLM or YPAD are carried as alternates.
Not highlighted in EK is that YPPH WX can go tits up at short notice with unforcast fog and strong local winds .YPPH should not be treated as just another Airport, given the remote location, lack of close suitable alternates , variations in local weather with only Cat 1 Approach.......
Worth recalling July 2012 when Unforcast Fog YPLM and YPPH caused
CX A330 to divert to YPHD. (CX 137 HKG-PER)
