what is different about washington, landing to the south, is that final approach lasts about three seconds. a very low altitude turn to line up with the runway is required after following the Potomac river for about 6 miles.
if you can obtain a copy of the river visual approach to runway 19 or view someone's video, you might understand.
all the best
CASE ONE
if you use the upwind power technique,/ assymetric/differential thrust, you are making the engine do the work of the rudder...and that gives you more rudder for the instantaneous corrections sometimes required. does that make sense?
