Yes, in that most laws in aviation are derived from engineering principles unique to aircraft:
One principle that determines the speed limits for these approach categories is the ability to make the gradual transition from instrument to visual flyng at a given contact height above the terrain:
1. the speed/height combinations are to chosen permit a safe flight path which allows visual correction for lateral and longitudinal deviations associated with the accuracy of the navaid upon which the approach is based.
2. And a height that allows for obstacle clearance and stabilized flight paths to the runway when considering the above correction
edited to add: to also allow a legal missed approach flight path
The detailed [FAA] stuff for diffent types of instrument approaches can be found in TERPS ---TERminal instrument APproach Standards.
