Initiating the go-around at minimums (about 250ft aal) still gives you 15 seconds before ground contact at 1000 fpm rate of descent....plenty of time for the engines to reach full power !
Agree under normal conditions with no buildings, tall trees, power pylons, etc., that may be under the flight path on approach. But by the time full power is on, you are well below 250ft, right? Factor in reaction time and I am sure we can agree on the rest.
The point I was trying to make is that in cases of loss of power the approx. 5 seconds AirBus manual at minimums may not be enough, more slack needs to be allowed to avoid breaching minimums.
