Tips to help a 77W survive CPT-SFO tonight needed (solved)

I have a very long and sketchy CPT-SFO route planned tonight, the distance is 8900NM, which I have flown successfully multiple times before with the 77W on 9000+NM trips from europe to the oceania. How harsh are the headwinds until you hit the east coast of the USA?

Have you tried windy.com? You can set the altitude and check the winds. They seem accurate from what I have seen.

Just ran a SimBrief on it and the flight time is showing 19:19. During my testing, I found out that at 90% pax load and 75% cargo load the 77W would do 20 hours and change (and this is including not using reserve fuel), you should be fine.

I’ll give that a try

Thanks for this! If its going to be 19:19 i’ll be fine. I’ve flown 19:43 with the airframe so this was very helpful as was the other comment.

Update, flight was completed and went perfectly


I’ll sort of be re-doing this flight backwards as UAL1126 SFO-CPT in the A359 or depending on whats online SFO-JNB as UAL1130… Just UAL 11XX to somewhere in africa 😂😂

Glad everything went well. Send me a PM if you ever want to do a flight together.

Bummer :( what for?

Right, windy.com or Windyapp is pretty accurate. But for Long haul flights, I would run a calculator like SimBrief parallel to it, to make sure things work.
