... thoughts ..
(a) the ops engineers do the sums in detail but there is a lot of variation in policy amongst airlines
(b) if AEO, the thrust is generally driven by maximising payload, while avoiding any overly high terrrain
(c) if OEI then the need is to get to a safe height and recover.
Two generic considerations ..
(i) basic calculation is V1 style failure and escape .. not really a problem if the track is the same as the AEO departure
(ii) often the more interesting is the post V1 failure .. if the V1 OEI case involves an escape turn .. and the real failure occurs after that OEI turn point.
For those airlines which consider this case, the pilot has only to follow the decision flowchart and the sums have all been done ...
For those airlines which don't worry about this case .. the crew is ON THEIR OWN beyond the planned OEI turn .. and best of British luck to you, good sir !!
It is germane for the captain to know which philosophy is adopted by his/her particular airline, I suggest ...
