All excellent information on here, keep it coming.
Di Vosh, what else would you call 20 aircraft attempting to arrive in half an hour when the system is configured to handle 12 in that time
I'd call it a **** system.
20 aircraft arriving in 30 mins is a slow day for a lot of single runway airports the world over, even worse given Melbourne is actually a two runway airport.
While ATC debate 5 knots vs 6 knots downwind in light wind, CAVOK conditions, crews are madly crunching the numbers on fuel and diversions when they should be concentrating on arrival. The Melbourne procedures need to change.
Get Golf online, get runway 09 online especially for landings, prohibit QF exits onto echo when 09 being used for departures, seek an exemption from CASA which allows ATIS nomination of 27 with 5-10 tailwind.
Penalise ASA management every time an aircraft is required to hold beyond NOTAM holding for non weather related delays. Once some manager's KPI might get affected, watch the arrival rate magically increase.
Let's get serious and get YMML out of the 1980s.
Le Pingoin is correct in that we do not quote tailwind/crosswind conditions for a non duty runway on the ATIS. My example of wind 120-180 at 14 kts was poorly chosen for this purpose, as a wind varying by 60 degrees should be reported as varying between those figures on the ATIS, however below 60 degrees, eg 120-170 degrees, unless that wind results in significant crosswind or tailwind for the duty runway (Rwy 16 in this case), the wind is to be quoted as an average from a single direction (so probably 140 or 150 degrees at 14 kts).
Here's a completely bonkers idea, straight out of left field for 120-170/14 knots.... Runway 09!!!!
