Question on 3/4 engine take-off on ferrry flights
Greetings, I hope I have the right forum and please excuse any inaccuracies in terminology.
I am interested to know the procedure for take-off when ferrying a four-engine aircraft with one engine inoperable. I have read a little about one airlines procedure of applying max thrust to the two symmetric engines and derating the odd engine and manually bringing up that engines thrust to max during take off.
How does this work in practice? Is there any automated procedure for doing an asymmetric derate in such situations?
