AOPA's account was a little unhelpful -- this affects turboprop twins.
Let me just clarify the terminology first. The regulation in question is Part-NCC, which applies to non-commercial operations of complex aircraft.
In EASA-speak, a complex aeroplane is one that is
* more than 5700 kg
* more than 19 seats
* a jet or multi-engine turboprop
or
* requires more than one pilot
In Part NCC, the troublesome bit is this:
NCC.POL.125 (b)
In the event of an engine failure during take-off, the pilot-in-command shall ensure that:
(1) for the aeroplane where a V1 is specified in the AFM, the aeroplane shall be able to discontinue the take-off and stop within the accelerate-stop distance available; and
(2) for the aeroplane where a net take-off flight path is specified in the AFM, the aeroplane shall be able to continue the take-off and clear all obstacles along the flight path by an adequate margin...
This has no equivalent requirement in Part-NCO, which is the part that applies to non-commercial operations of non-complex aircraft.
