The aircrafts glide way too far on 0 power

I both cases the approach speed is 1.3 x 1g stallspeed so the margin is percentage wise the same. In absolute values (kts) its higher obviously.

Also threshold speed may not be below Vmcl and not below 1.1 x Vmca if I’m not mistaken but I think this is more relevant for turboprops and only at low landing weights.
