de facto - out of interest, what is your opinion on min assumed? Can you in fact interpolate the tables, making AGP 31degrees, or are we restricted to block figures as with other performance detail?
Not sure what you mean by AGP.
But if you mean interpolate to use 1 c above min ass temp then not worth it anyways..your take off thrust will be basically the same as with no ass temp.
If you can not use assume temp higher than the minimum assume temp due to your climb limit weight then do not use assume temp at all.
I check the runway limit weight for runway lengh available and climb limit weight ,if thats ok i use speeds for the actual weight at the actual temperature.
