It's VEIM. The landing distance is not a problem. Difference between Full and Flap3 is about 150mtrs. I was presented with data of some landings about the ground speed and ROD. invariably in all landings the GS was 150 to 160 kts and.ROD was greater than 1000ft/mt. and unstable approach. Even for 3.5 Glideslope unless the Ground speed is in excess of 170kt the ROD shouldn't be that high. Except landing in tailwind what other reason could be there? And why would anyone land with Flap3 with that Ground speed?
