Very informative discussion
Interesting to read about this latency issue on the visuals, as I have always perceived it.
I always feel sick taxiing if it's prolonged. And I am sure this is why sims are harder to land, because the visuals don't give all the clues as the real aircraft does. I now forget about flaring nicely in the sim, because I see it as wasted effort with only partially invalid information.
Sim instructors, and engineers etc, get enough exposure to these differences, that they don't notice it, as much as those of us who only visit twice yearly.
As far as crosswind landings go, I have always ignored Airbuses advice for landing or takeoff. Following turboprop or Boeing procedures gives a much nicer, more controlled arrival/departure. Why is it Airbus don't seem to like crossed controls?
