The extract you took from my post is more correctly summarised with a longer quote:
more likely is a somatogravic effect? This is a very powerful, and widely understood phenomenon which would have seen him push the nose down more than required. The only protection against this in IMC is rock solid instrument flying skills.
Somatogravic illusion kills even when the associated manouvre has been practiced countless times. Far more frequent in FW accidents, it is a depressingly frequent contributor to CFIT. Which is precisely what this accident would appear to have been?
Only robust instrument flying techniques offer any protection when electing to fly manually.
