All that is usualy covered in the individual runway TO charts
provided by the Co (at least the ones Ive worked for).
So if rwy 28 dictates a much lower TOW than rwy 10
- check if rwy 10 gives a better weight with the present
dw comp (might only be a few kts). If it does then ask
ATC for rnw 10 due op requirement
- if its rnw 28 hands down then get the best TOW taking
into acount flap, HW comp, EO proc, etc.
With this rnw 28 weight
- if payload critical then calculate a diversion point (thru
Ops) from a suitable enroute airport. This will lower your
variable reserve and increase payload. This assumes you
havent finished refueling. If you have, then....
- If fuel critical (or is already onboard and no defueling)
calculate your new payload.
