Title: SFO-HGK 777-LR with 9,990 nm range can't carry cargo?
Post by: LoganDCA on January 13, 2021, 02:21:26 AM
I have a KSFO - VHHH 777-LR with 9,990 nm range that cannot take cargo at any price. The return is 100% CLF with a rich rate. Am I doing something wrong?

The game takes into account prevailing winds so your flight is longer than advertised on one leg and shorter on the other. When creating a flight close to it's range limit, check the little question mark icon next to each leg and see how it works out.

I read somewhere that in the real world jumbo cargo planes fly in a constant eastward direction around the globe so they get tailwinds and not headwinds. Makes sense to me!

My plane is a 777-LR with 9,990 range. That segment is 6,847nm with headwind. I think the program thinks it's a 777-300. Here is pertinent info for the plane/info under "?":

Nominal still-air range: 9990 NM
Seating configuration   Y: 176, C: 30, F: 4

KSFO-VHHH
Total scheduled flight time: 14 h 28 min
6306 NM
-36 kts
6874 NM

Payload limitation (B777-300): 14 h 55 min
74 pax

It's also worth pointing out in this instance that cargo demand at HKG is very asymmetrical. Pretty much all cargo demand at HKG is on the flight out to another airport, not in to HKG.

As Mort mentioned: Did you check if there is actual demand. In my "modern times" game there in no demand between SFO and HKG, just a negligible 500KG!

Nope, it's asymmetrical cargo demand. Check demand both directions to HKG and you'll see. Potential demand on HKG-SFO is 422,890kg a day, return is 1820kg.

You are exactly right! That made all of the difference. Thank you.
