And the term SLF must stay, otherwise all the network palnner have a serious problem. And then, there are no customers = passengers = self loading freight left to fill the planes, so we cant let that happen, as the main principle in ntwork planning is:
SLF = (X*SLF)/SC whereas X*SLF = PAX!
Puzzeled? You're definietly no network planner then!
Here's the solution:
Seat Load Factor = Number of Self Loading Freight Divided by Seat Capacity whereas Number of Self Loading freight = passengers!
And we don't want to ruin the oh so beautiful symetry of the equation, do we?
