Perhaps not
To those recommending the use of the manual W & B charts/tables, they often just have a few of the 6 possible charts:
1. Flaps 5 or 15 and sometimes 20, each in turn has
2. 'high thrust' or 'low thrust', where low means more than 15% derate using Assumed Temp.
Depending on what Flt Ops policy incorporates on the printed forms and charts, the load sheeter may have limited choices. I've normally seen just the high thrust versions. It's assumed that typical ATOWs are well within the RTOWs and not limiting so the pilot may have to use one of the available combinations for T/O. In case they aren't, then it's a special case - if the AFM page cannot be found (it doesn't seem to be popular knowledge) it's time to wake up the Tech Boffins, at 2am with a call from BGSF!
