Cargo is usually carried on pallets, and not LD3. I wonder what are the normal loads for these aircraft, pre-covid I mean.


For passenger carriers, a considerable amount of cargo is shipped in cans.

Re: A350-1000 versus B777-300ER

Pretty much dominates all trunk routes from 8 hrs - 15 hrs. For example, HKG-JFK. My shortest 777-300ER flight (excluding KLM flights that continue to another destination, like KL-Jakarta) was 5 hours, but the vast majority have been around 12-13 hours. It is pretty well suited for the Europe to As...

Re: 747-200/300 with GE engines...Why the lower fuel capacity?

At that point in time the GE CF6 claimed to be 5% more fuel efficient than the JT9D-7, the later certified RR engine had a lower TSFC , but was far heavier, thus reducing the max payload. Did the lower fuel capacity on CF6 747s reduce the range much? Not to totally derail the thread, but were the l...

Not factually correct. AS I mentioned So you ask a question which you dont know the answer to, and then argue the answer? PD may divert to YHM because its cheaper, easier to restart, etc. YYZ is ten feet away from YTZ so its probably not a good idea to attempt to land there if you cant land at YTZ....
