Every airport has their own idiosyncrasies. So SYD 16R with the prevailing wind means that turbulence generated by the buildings at Sydenham and notably IKEA, will affect the aircraft at around 200ft. Once we're clear of them and the land flattens out (ie Qantas Drive and the clearway before the threshold of 16R) the land heats up (and cools) at different rates to the buildings. This generates a ‘dip’ where the aircraft feels like its at the top of a roller coaster and is starting the drop so more thrust is required to arrest the sink and then it’ll need to come off again before touchdown.
I can’t actually remember the 777 ever being affected as much as the 737 most likely due to the amount of inertia that is carried. It just cuts through the air nicely.
