Hi A37575,
Try searching something like:
Go around, thrust reduction altitude oei [Archive] - PPRuNe Forums
PANS OPS 4 does NOT include an allowance for a level acceleration any more. It is up to the operator to ensure you can make the published GA gradient.
We can generally outperform the published gradients with all engines operating, so accelerate at our normal AA. (1,000' agl)
We have to do a calculation before each OEI approach to prove we can make the minimum gradient, and then only accelerate at MSA, or the first published stop ALT or at the acceleration Alt if published (eg. Grenoble).
