This guy - Harry Lordings, an ex USAF test pilot
Harry Horlings, perhaps ? FTE rather than TP and RNAF rather than USAF but, no matter. He is very pointedly motivated by Vmc matters and has some good stuff to relate.
However, if I recall correctly, did not the ATSB report (without going through the thing again myself), suggest a significant causative problem related to a rather common and inappropriate technique for simulating OEI on turboprops ? One which sort of invalidates the OEM data ?
