NAROBS, you are confusing speed with acceleration. 55 m/s is speed. You seem to be assuming 55 m/s/s (=~5.5g). That would only be the case if the change in vertical speed all occurred in one second.

Up Gust

@Bloggs --



?? A severe enough updraft will cause pitchup simply from differential vertical wind speeds between wings/nose and tail.

(But excellent points on "forgetting to remember trim"...

@highflyer -- We'll have to agree to disagree as to "stable" as a requirement I think. I'm positing a possible last-minute achievement of "shallow" (enough). (And again, lack of a comm attempt is not...
