Any word what the perimeter is for a useful load? Embraer's official data for the standard E190 is:
Take Off Field Length, ISA, SL, MTOW 6,745ft 2,056m
Take Off Field Length, ISA, SL, TOW for 500nm 4,157ft 1,267m
Does the "SR" do anything about it or is it just the steep approach modification? From the paper, 500nm would be the max. range with a full load. Places like Nice or Milan would be a stretch, and Madrid, Barcelona, Warszawa, Vienna out of reach.
Is this possibly the reason for a number of E170's as well?
If I remember correctly this is why a few RJ85's appeared as the 100 couldn't make it somewhere (MAD I think) full.
