We have no any RWY limited.We get the load sheet and OAT is lets say 23C and we get the 22K 37C assume refer to the current load.Again in the same conditions and the same weight we get 26K 56C assume value...We get less N1 than 22K and this means more protection of the engines.
According to our company procedures; we get the load sheet,first 22K assume considered,if it's not possible than 24K assume,still not finally we goes for 26K assume...
Could you please let me know why do we both do 22 derate and assume?Is it your procedure too?
