(4) about the "90 Kg"
Working forward using avge pax = 88 kg avge baggage = 17 kg so avge pax+bag = 105 Kg
so payload for freight+mail = payload -[nbr pax * 105]
on some routes for some carriers results in negative payload for freight+mail
That's when calculated the avge pax wgt backwards to the 90Kg.
I have route, payload, freight+mail, nbr pax
deconstructing this where total_weight_pax = [payload -{freight+mail}] and dividing result by nbr pax gives 90 Kg
All route data from transtats at the US DOT.
Curiously there seems to be no particular data on the average number of checked bags per pax. I found a couple of references that suggest 1.8 bag/pax and the EASA study suggests that avge baggage weight/pax 17Kg
(trying to calculate baggage containers used to estimate the potential containers for freight+mail)
I'll try re-running the numbers with vatiations derived from your info.
Thanks and any other helpful remarks are appreciated
