Stepclimbing KJFK-YSSY

Ok, I’m currently about to take off and i was wondering what’s the best way to step climb in terms of fuel consumption?i know simbrief plans stepclimbs but it seems to be a little too fast, especially for a 19 hour flight…

Are you using a Qantas 789?

Yes i am…

It wont work. I’ve done a 15 hour flight in a United 789 from KSFO-WSSS I had around 10 minutes of fuel left when I landed

So can you explain this? They made it safely. So you should make it if you put passengers at 0 and same with cargo but full fuel. When you fly it fly the route they chose as they spent months planning the most fuel efficient route.

oh really, welll.

You need to plan your weight and balance, along with speed properly. And that’s false, because I got KLAX to FACT nonstop, full throttle full flight past MTOW, and still had fuel


What I would do is Climb to FL100, then FL200 10 Minutes after, and so and so on. Try to use a low V/S of around 1200-1500

Just also note that ATC gave them some shortcuts throughout the flight to arrive quicker.

What was your flight time?

Around 15 Hours. With Full Throttle, you’d usually get 13 hours

If able, climb at 100 FPM to the next even flight level every 4 hours or so. Deer did that and we were fine.


Oh nice, what plane did you use?

ok cool :)

787-9 Virgin

I flew on this route yesterday without any problems with 190 PAX and 4,500 kg of freight. On these kinds of routes, you have to manage the steps to climb. I didn’t manage them well, so I arrived with only 9 minutes of fuel remaining.
I Will advice to start at FL280 or FL300 (depends fuel and cargo) and climbing every 3-4 hours

thats crazy you did it with cargo and that many passengers. i just took off like 30ish mins ago and i just reached fl300…
