How about engine failures at other points during the take-off profile, eg during rotate, V2, thrust reduction? Missed approaches from somewhere other than the minima, eg on the runway (rejected landing), from an altitude above the missed approach altitude?
With tailored procedures, we do look at balked landing, but other than for the validation in the sim, I have not seen it practised. While we do validate EO procedures in the ac, we do not validate balked.
What I will say is balked performance is typically dismal, especially in the conditions that were at Dubai. You had very hot temperatures, with the ac bleeds on, max flaps, landing thrust, all with windshear conditions.
Forget all of the rubbish on the certified climb gradients, the conditions at Dubai were far different, and if you look at BCOP, you would probably see double digit climb grades under those conditions.
