I was picking random numbers to try and spell out that cruising speed isn’t a huge safety risk, but landing speed is. Notice that the slow speed (55 kts) I picked is legal under MOSAIC but the higher unsafe speed (80 kts) isn’t legal, and this illustrates that the FAA kept a fairly sane stall speed limit.

The fact that the stall speed limitation closely matches the existing limits for light singles shows where the FAA draws the safety lines. Although MOSAIC apparently allows twins, they keep the stall speed limitation at a sane number.

The only thing I don’t fully understand is them differentiating between 59 kts for a sport pilot, and 61 kts for a light sport aircraft. It feels a little arbitrary to draw those lines differently.
