Strong Easterlies are a fact of Summer life at PER. In the 727
yonks ago we used a howgozit "PNR-ish" chart for the routes
MEL-PER and SYD-PER using KGI as enroute alternate. Only
once we did pull in there for PER x/winds as 06 was closed
due WIP.
BTW why wasn't bloody 06 offered to begin with?
VC9 true words. A good example was Kai Tak IGS13 on a bad
day. Nowadays its Chek Lap Kok with an approaching typhoon
and a strong Southerly.
