Whilst I tend to agree about losing the data, I am a bit perplexed as to how the emergency services helicopters suddenly won't be able to find a hospital.
Let's take an example of YXPD. I know there is a helipad there, a VFR helicopter flies in there fairly regularly. I have driven to the helipad. It is not marked on any charts that I can see, nor can I find any lat/longs to it anywhere.
I will concede I have only looked in ERSA. The only place I can find any reference to it at all is in the Encode/Decode area.
I only looked at that one hospital as it is a local one to me, but I can't recall any of the Perth ones being on the Perth VTC (happy to be corrected on that). May be different over east?
Either way I don't think the data should just be "dumped" but I am not sure it is all about the Emergency services suddenly being unable to find a hospital.
