More interesting than the decision to commence approaches is the fact that lots of narrow bodies landed on 16L in heavy rain and the ATIS reporting that a taxiway was closed due flooding, I assume most/all the Boeing’s used flap 30 due to the crosswind and wind shear. All the while notams that we’ve all come to expect ( and maybe ignore) state;
H253/20 A) YSSY B)
2001152333 C)
2002292000
E) RWY 16L LOW FRICTION VALUE
AVERAGE VALUE 0.24, 0.29 AND 0.31 BLW MINIMUM VALUE 0.43
LOCATED 3M EITHER SIDE OF RUNWAY CENTRELINE
BTN 500M-700M FM RWY 16L START OF TAKEOFF
H255/20 A) YSSY B)

E) RWY 34R LOW FRICTION VALUE
AVERAGE VALUE 0.23, 0.36 AND 0.41
0.41 BLW MINIMUM VALUE 0.43 LOCATED 3M WESTERN SIDE

Thats 20% of your ground roll notam’d as below minimum required friction levels due rubber build up if you land on the 1000’ markers. Or a quarter of your landing roll notam’d as below minimum required friction levels due rubber build up if you touch down at 1500’ ( in heavy rain, with less than full flap, maybe carrying extra knots for gusts).
Things are starting to stack up.
I might buy shares in Sydney Airport Holdings.
