You've may have covered this before, but when you get your roster, what does "perfect" look like vs "worst possible".

I'm sure the latter occurs more than the former, and it changes but if you had your pick over say a 1-3 month period, what would it look like?

I assume all Aus flights ex-MEL would be top of the list? But what "structure" would you want?
 
On one departure, I was about #87 in the queue, which Disney style, went all the way around the airport....

Ahhh... our Captain must have got there before-hand and got a fast-pass ticket... :lol: (which we used frequently when at Disneyland at the start of our trip)

When I was on the 747, I mostly flew to London via HK, as that trip started and ended in Melbourne. My number two choice was London via QF 9 and 10...again operating from Melbourne. NYC trips were good, especially when they were tied into the AKL-LA service, as that meant you had less time in LA.

Variety is very much lacking in the route structure these days, with the 380 only flying out of 6 airports (London, Dubai, Melbourne, Sydney, HK and LA). The London trips all either start or end in Sydney, so the only trips that avoid Sydney entirely are the 93/94....which I'm not otherwise keen on. So I guess my roster choice these days will really just be all London, taking the 9 on the first sector and the 2 on the last....and then I'll try to swap the last sector with whoever has it.
 
Hi JB,
I was on QF10 LHR-DXB last week and looking at the flight path I noticed that the flight avoided the Syrian airspace (continuing a bit further east of Turkey before entering Iraq) and I suddenly wondered how many countries are no-fly zone for commercial airlines? Do the Turks or Iraqi controllers remind you to stay away from Syrian airspace in case of emergency?

We've often flown in close proximity to various no go areas. Syrian airspace was used until a couple of years ago. The controllers don't say anything unless they need to.
 
JB, Sydney Airport report about future expansion.

Airport says the sky's the limit

What do you think about this from an international pilot's perspective?

Mostly gibberish. The letters cover some of the points.

Firstly, whilst I'm not a road designer, I've never seen a successful loop road where all traffic is directed past terminals that you don't want to use. The QF traffic shouldn't have to drive past Virgin, and vice versa. The first terminal invariably clogs up the entire road, as people (i.e. taxis) try to get from the far right lane to the left, at the last possible instant.

The curfew in Sydney is an issue. The airlines are rarely offered any relief from it, even when trying to recover from days of bad weather. Curfews can't just be considered in isolation. As flights travel around the world they have to fit in with curfews at both departure and arrival ends of the flight. That basically means there are large periods of the day, when flights can't depart (or arrive) from various destinations. For instance, you can't depart Sydney to London from about 8am to 3pm, because of the London curfew (which is a lot more relaxed than Sydney's). Going the other way, you can depart from about 9pm to 11pm, and then from 6am to about 2pm. Commercially some times are useless, and, you actually have to mesh the arrivals and departures together, otherwise you don't have an aircraft to use.

The upshot is that these empty periods at Sydney are empty for a reason.

But, if they were able to fill all the arrival and departure slots, which I'm sure is a Macquarie wet dream, the overall result would be chaos. Flights that were delayed would either be cancelled outright, or have to wait hours for slots to become available (this happens now in Europe...divert and the chances are that your crew will run out of hours waiting for a slot). So, have a thunderstorm in Melbourne, or fog in Sydney, and the ability to rebuild the schedules would simply disappear. And of course, those weather events never happen, do they?

The curfew should be relaxed for arrivals onto 34 and departures from 16. If the entails buying the entire suburb on the other side of Botany (whatever it's called), that would seem a small price. A second airport should be built, and not in some mythical far away land, connected by a fast train that nobody can afford to build/buy/use. There were reasonable options for a second Sydney airport, though the decades of procrastination have probably ruined them too.

Thanks Markis.

They looked like generic tending equipment to me...

Anyway, this prompts a question for JB or anyone else who may know - when an aircraft is at the gate why don't airports and aircraft manufacturers have provisions for the connection of external power supplies via cables, say, via the jetbridge?

An APU is a rather inefficient way of powering an aircraft, isn't it? Sort of like why our Melbourne metro trams and trains aren't diesel powered.
 
mjt57,

The APU is actually quite efficient. Between an APU and the ground handling generators the situation is pretty well covered.

What else were you thinking of as an alternate?
 
Wouldn't that be very non enviro friendly?
An electric train or tram derives it power from the grid which is a mixture of coal, gas, hydro and renewal energy sources.

Running them on diesel causes more local pollution, noisier and is a less efficient method of power production.

I ask the same about running what is essentially a simple cycle gas turbine (the APU). The ones that I've operated in the past had a max efficiency of around 30 percent.

I was wondering about airport provisioned external power sources, via cables connected when the jetbridge is set up (or some other method). Wouldn't that be better than having dozens of APUs operating in close proximity to each other?

Of course, there's the spectre of the privately owned airport corporations using this as a further method to gouge the airlines (and ergo, the travelling public).
 
According to JB747 Ground power is usually used, question being why use gensets if grid power is on offer, unless SACL are in the electricity market in which case we know the answer!

As already said, it's power supply switching. Prior to pushback, it will be from ground power to the APU, and after start from the APU to the engine driven generators.


Where possible, the aircraft are run on external power when at the gate. That allows the APU to be either shut down, or operated under a reduced load, which gives substantial overall fuel savings.

don't Macquarie Bank have a stake in SACL? I'm sure they also have a big fist-full of power generating station pie...
 
What about 9 and 10? How/Why are they SYD starts/finishes?

The patterns are built with a paxing sector from Sydney to do the 9, or they finish with a paxing sector after the 10. There aren't any patterns that start and finish in either Melbourne or Sydney. I expect they've looked at all the variations, and this is the cheapest crewing outcome.
