Something that I’ve noticed about the A350 on approach is that the VLS in clean configuration is too high. The top of the amber strip on the speed tape is above the S-speed, which shouldn’t be possible since the S-speed is the minimum speed in clean configuration; in clean configuration the VLS should be equal to this speed.
This means that there is a high risk of A.FLOOR triggering if the plane is slightly below green dot speed with no flaps extended.
