Santiago for the 787 if they can get 330 mins ETOPS/EDTO and RNP AP. |
Was told to maximise payload on departure . |
Fair enough. Not sure which obstacles in Syd that'll fix but sur
Edit. Doh, ex scl obviously |
I think the RNP AR refers to the SCL-SYD sector ! |

Sydney based cabin crew have just been officially told that they will be endorsed on the 787 later this year as the incoming aircraft will be based there, so I’d say SYD-SFO is a given now with Santiago and Tokyo also in the running. |
Sydney-Dallas Brisbane-SFO Sydney-Santiago Sydney-YVR A380 onto Sydney-SFO to replace the 747. Don’t know how they will solve the JNB issue. my $0.02 |
Is there another engine bump on top of the one they’ve already got available ? I have heard they will struggle out of JNB back to SYD with anything over 25 ℃︎ or RWY 21 departures ? |
I believe that the main issue for the B787 is the "Return to Land" function in the OTP. The certification requires the aircraft to be able to land back at the departure airport after reducing fuel load to below MLW. In JNB, the obstacle clearance in the missed approach is the main issue that results in restricting the the allowed MBRW to be marginal to fly to SYD, can make PER with no problems.

I never was good with my north and Souths - .... We are a long way from a landing spot when we fly past Santa and that limitation has never been brought up before. Put it another way, 3000nm from Santa Land is the Mediteranean or Central US or the "Stans". That is a really long way with nothing in between. And finally, cargo fire suppression is one of the fundamentals of EDTO (ETOPS) along with separate maintenance for critical systems etc. |

FAR25.1001 states the aircraft must be capable of performing a one engine inop go-around with a minimum of 2.1% at the same airfield it has taken off from considering 15 minutes fuel burn plus 15 minutes of fuel jettison. No requirement to land below MLW as you state. |
Well kids stop arguing. FAOR is in the onboard performance tool and running rough numbers it can do the job with perhaps some restrictions on days above 32* which automatically calculates return to land function. Fire suppression 345 minutes. Polar approval tick. Join the dots ....? |
I’d add that provided the issues with Perth Airport get ironed out (and I’m sure they will), I would hazard a guess that capacity issues can be addressed by adding services through Perth. That would also be a far better service for those customers from Melbourne/Adelaide etc, to connect with, who don’t live in Sydney, or to the North/South Pacific/across the ditch. Additionally it would give the option to bump a few pax onto when the weather isn’t playing ball for the direct Sydney to take all of its booked load. |

Full pax, Easy! As a rough comparison...
BNE-LAX (6283nm) is 320nm further than JNB-SYD (5963nm). Todays BNE-LAX 789 flight left with all seats occupied, 7 tons of FR8 on top of pax bags and was planned to land in LAX with 2 hours EOD. Transpose the same AC and payload to the current conditions at JNB (17* and calm) and it can do it with a couple of tons to spare. If is was actually 30* in JNB, adjust for the fact that JNB SYD is 320 shorter than BNE-LAX, dont need 2 hours FOD, and lose the 7 ton of FR8. Still fits in OPT. |

? The 787 can't get joburg-syd vv with a full 236 load? Surely
|
Does the JNB-SYD and v.v route provide a lot of freight business? - if so then the company will not want to lose that revenue surely...

Latest BITRE data is for January 2019. During that month QF carried 157 tonnes inbound from SA and took 13 tones outbound. Add another tonne or two for PO mail. Not a lot for a daily 747 service!
157 tonnes pm is around roughly AVG 5 tonnes a flight |
In summer we are lucky if we can carry that, a lot of it is flowers. |
