But.... Also look at the number of topics. the microlight design standards are not including passages dealing with pressurization, hydraulics, autoflight etc., etc. etc. You should have seen the 11 month regulatory fuss when I tried to merge part 23 oxygen systems to approve an oxygen system into a part 27 helicopters - which standard has no reference to oxygen systems.
Look at the emergency exit design requirements for a microlight, then compare them to a part 25 jet. Lots of part 25 words that are not the least needed nor applicable to the microlight.
Interesting though project though, yes, how many people in the headlines....
