controllability is in their opinion better at a reduced flap setting for strong gusty crosswinds.
correct.
honestly, its so obvious for any real pilot with work experience that reducing flap settings to a minimum needed and approved on a gusty day with a strong crosswinds helps a lot and is a common procedure, that basicly in real life nobody from a flight deck would start a debate about it.
so this thread of course went after few postings stupid with no useful information.
the only thing which makes it worth reading is the fun about all the dreamers here who continue to debate in which direction ever and fail to see that seriously debating this obvious question by itself for several days proof them to be very fake and never had a crosswind landing on whatever aircraft.
for a real pilot , even a private one with some hours logged, its not a question if its a better idea to land a cessna 172 with flaps 40 or flaps 20 when a strong and gusty wind from the side blows.
cheers !
