Bradley...look at what I bolded in the quote.I experienced somatogravic issues during my most recent missed approach in IMC in the 182RG. Everything felt and sounded fine while I was fiddling with the radio and when I resumed my scan I was leveled off and accelerating instead of climbing at Vy. Contributing factor was probably that this was the one one with the bigger STC'd engine and has 15% more power than I'm used to. Very real scary phenomenon but I don't think it was the cause of this accident.
More likely, especially with underslung engines, is that they had excessive pitch up due to skill/scan/distraction, and then overreacted.
You had a somatographic illusion...yeah, they are powerful...(I don't know this first hand, but the classic lean over and back and grab a map makes it into lots of "What I Learned from That" articles).
But you and you alone did not enter a 50 degree dive (with Gabriel Ardvark2zz) calculating that would result in -1G.
This is two professional guys and let me repeat- I find "a momentary level off" to be within the realm of plausible screw ups...But to 1) Execute an OK climb for 2000 feet and then nose over into a 50 degree dive??? without taking a peek at the attitude indicator???
