just an observation (maybe a rant...whatever)
but when I see a guy climb 2000' using VNAV after 2,3,5 hours of those GE's just purring along whilst we're somewhere remote, All I visualize in my chick-pea mind is that valve, duct junction, elbow bend in some far corner of the engine nacelle deciding Yup...this is when I'm gonna blow.
Why impose that roar in the crc, cabin, etc when a little VS climb keeps everything so tidy.....
Am I the only one?
