Not Sure if there is any significant difference in weights / Distances, between the 190 & 195

Figures for E190 at 114,000 lbs (51,710kgs) (over MLW)

Unfactored Landing Distance for Flaps 5 = 3286 feet (1000 metres)
Normal Length Required dry (x1.67) = 5487 feet (1672 metres)
Normal Length Required Wet (x 1.917) = 6299 feet (1919 metres)


Unfactored Landing Distance for Flaps FULL = 2911 feet (887 metres)
Normal Length Required dry (x1.67) = 4861 feet (1481 metres)
Normal Length Required Wet (x 1.917) = 5580 feet (1700 metres)

SLAT/FLAP FAIL 0/0 - Vref = Vref Full + 60, Unfactored Landing Distance for flaps FULL: 2.41 dry / 2.84 wet

Slat/Flap Fail Length Required dry (x2.41) = 7015 feet (2138 metres)
Slat/Flap Fail Length Required wet (x2.84) = 8267 feet (2519 metres)

Vref at 115000 lbs Flap 5 145 KIAS, Flp FULL 136 KIAS
Vref Full + 60 = 196 KIAS

*note used max weight for worst case scenario

P-Air,
Good job on the figures, Max landing weight on the 195 is 45T so they are all slightly less than that but close enough for here.
