Re: Vertical Speed
A 1000 fpm vertical speed up sounds like a lot, that is, if it lasts a minute or more. It didn't. The A/P handled it very well and within seconds it was back to neutral. It was like a bump experienced in moderate turbulence. However, approximately 12 seconds later, it increased dramatically, about the time the sidestick was in use by the PF, that's when it increased to 5200 fpm.
