747 Yaw oscillation
After forty odd years of SLF flying I finally flew in a 747 last week, Vancouver/Tokyo by Japan Air Lines 747-400. I expected a smooth ride but was hugely disappointed. All the way, apart from a couple of ten minute spells the tail, (we were in row 62) oscillated in yaw, from almost nothing up to about an inch or two and about 100 cycles a minute, a jerky and tiring ride.
Is this typical of 747 of does someone need to have a serious word with the yaw damper? Would the pilot feel it at the front?
