Whilst the low speed RTO with an outboard engine failure would arguably be one of the most difficult manoeuvres in the -400, the other being an outer engine failure on the upwind side in a strong crosswind just as the gear is lifting off, nevertheless as long as the appropriate thrust for the weight and not some macho thrust has been set, it is easily done (with correct training) at just 30 or 40 kts and in RVRs where you can only count a few centerline lights. There may be a bigger issue here I suspect. They were not very succesful at completing an ILS with a servicable aircraft at Bishkek in January.
