FL40 1380 m actual landing distance.
Usable glide slope landing length, assuming they did not go below, is 4575ft. Flap 40 actual landing distance is 1380m=4527ft. A legal margin of 48 ft? I am not trying to split hairs here, I am simply saying that looking at total runway length and equating it to legal landing distance is not correct. You have to look at available runway distance. It's an easy mistake. I know because I have made the same mistake, just not with consequences! On a razor thin margin like what happened in BUR it could be the difference between taxiing to the gate or ending up in the EMAS..
