Tartare: I assume what you are saying is that RNP inbound south down the Hutt Valley for a Southerly landing is already operational?
But could a fully loaded wide body launching to the North from a runway extended to the north into the harbour, then having one engine out, clear the Newlands pylons, or would it have to turn right and divert along an RNP track up the Hutt Valley
I think Slamer is referring to the Single Engine departure procedure to the north up the Hutt Valley. It's has some similarities to the RUGDI SID and avoids going direct to WITBY and the gradient on that track. Hence my question.
